Some of the temporal concepts stolen from geography that we'll have to deal with: event extents, event resolution/density, temporal scale (especially with respect to animation),... I think the eventual solution will be JavaScript-based, maybe nearly the size of OpenLayers effort.

I have a little reporting project that I’m thinking about related to GPS tracking. Bouncing the idea off of folks here in the hopes that someone may have tried this somewhere else or maybe has a better way. I need to generate a slider control for handling sorting through the GPS data for individual vehicles on a daily basis. The idea is to build a rapid, visually oriented, lookup system for the data. To begin with, I would like to start the process by querying for the data for a single GPS ID for a 24 hour period, generate a time based slider control that can be used to pick a point in time, and then have a slippy map (OpenLayers) auto zoom to that location, once a location has been decided on. I found an example on the Openlayers site for the slippy map part, I have a service (yet to build) that can grab the location data by time increments of 24 hours, but the slider part is looking like it might be a bit intensive if built in a standard way. The data for the GPS devices can come in all sorts of time resolutions, some are based on 15 – 20 sec updating, while others are using 3 sec update increments. The resulting 24hr dataset can be somewhat sizeable as a result. Here is my weird idea. Make the Slider into a MapServer map call that is aggregated at certain time increments (Map tile pyramid levels, only in a single direction, left/right) if the slider is zoomed more resolution of time appears for picking the location in the slippy map. The slider becomes a real wide but not very tall map but only for displaying, and picking by the user a new time increment. This approach should therefore compensate for browser view size as well as density of time data, by making an appropriately sized, scaled tile on demand. It should also be adaptable in the future to starting out with larger time increments to show where GPS activity was, and then to zoom in on that time increment for detailed analysis. Ok, I’m ready, tell me it’s a stupid way to go . . .

Your understanding of geometry is a bit off here. In a query result set, each
row is a feature, and a line feature would be made up of two or points; a
curved line feature, of course, would be made up of three or more points.
What you are getting in the result set above is a bunch of features, each of
which are a point repeated twice. I think what you really want is to create a
single line feature from all these points. So, you would probably do some kind
of an aggregate on these points. I don't know the functions available in SQL
Server, but there must be an analog for Postgres's aggregate functions. You
want to collect all the points and make a line feature from them, and then pass
that to MapServer to draw. You could make a view that does all this, and then
call the view from MapServer.
Hope this helps.

Hi,
The question, if I understand is correctly, is relevant. In EPSG:4326
shortest distance between two points is better expressed as a curve than as a

Interesting spin; didn't think of that. However, note that, as Brent pointed
out, the OP is SELECTing the same coords twice, so, in effect, they are two
coincident points of line length zero.
You may find some workaround from GDAL. Ogr2ogr is having a segmentize
option for this purpose. It does not support real curves either, but it
creates intermediate points so that linestrings are shorter and thus follow
the curve better. See http://gdal.org/ogr2ogr.html

Any ideas on how to make it faster. Simplify the data for the that zoom level. If you are all the way zoomed out and drawing all the data, then the shapefile will be fastest. An index does not help if you are drawing all the data as you need to do a full table scan anyway to get all the records. It is simply faster to read 200MB from disk than from the database because the database has to fetch the same data and may have to jump through some hoops to get it out of extended storage, then it has to encode the data and send it over the connection and the client has to decode the data. Do you really need all the resolution of the data at this scale? If not create another column and simplify the geometry into that column and set up your mapfile to query the simplified data at this zoom and to query the detailed data as you zoom in. All of the above is great advice. Additionally, implement a tilecache server; why redraw an image if it has already been drawn. That said, while a db is going to be slower than the file system in many cases, there are many reasons why your db is performing so slowly. Thirty times slow is too much, and 30s for a query, no matter what query, is wrong. Benchmark your entire stack to find bottlenecks... Is the query itself taking that long?

Thanks in advance for any suggestions, Hi Puneet, I have done this in the past and there are a bunch of moving parts. Here is what I did. 1. got a copy of NED2 data for the US. 2. create a gdal .vrt file to pull all the files into a single virtual file 3. wrote a simple C fcgi program to take an x,y and get the elevation from the the NED2 data. http://imaptools.com:8080/cgi-bin/getElevation.fcgi?lat=32.6628646lon=-86.8800962 4. I used pgRouting to compute a route and then took the route geometry and added sample point along the edges where needed, and hit the fcgi service to convert the points to elevations and then plotted the elevations against the their length along the line that the x,y represented. I also think I may have wrote an app where you could pass the route polyline to it an it would generate an image of the elevation plot. 5. Then wired it into the web page as an ajax call of as a image url that gets updated. Thanks for the details, Steve. All this is way more complicated that I was envisioning.

It is my expert opinion that, with documentation and all, tilecache will take 35 mins. Any more and either the person doesn't know what he is doing, or is hoping to take the client for a ride.

I'd prefer MapProxy, or Mapcache, over Tilecache, to be able to support GetFeature requests, but in this instance that will not be needed anyway. That's about my take on it, maybe a couple of hours, but I've just been quoted 3 days by a support team to do this, at NZ$170/hr. (current exch rate is around .77, so maybe $2600US??? for the job) I'm not a professional at this, but do such things as a prototyping playing exercise at home... a formal installation will need documenting, etc, to a production server standard, so perhaps a few more hours, but that cost seems excessive. Hence my question here, to get an expert opinion of what such a setup should cost. Ideally a few such opinions to give me a robust sample size to go back with :-) I've also asked another provider for a cost. My guess is they will be considerably cheaper. --- On Sat, 3/3/12, Puneet Kishor punk.k...@gmail.com wrote: From: Puneet Kishor punk.k...@gmail.com Subject: Re: [mapserver-users] Setup advice please?

Never, never touch the stuff that comes with the system if for no other reason than you just don't have to. 2.

The apache docs at http://httpd.apache.org is pretty good. But, since you are using Mac OS X, you can simply use apache that comes with it. Just make sure the ScriptAlias directory is set to the cgi-bin directory you are hoping to serve mapserv from. However, if you want to use your own installed apache (it seems that is what you are using because you provided /usr/local/apache2 to your mapserv config), configure it properly. Its config file is at /usr/local/apache2/conf/httpd.conf Just make sure that your Mac's built in apache is not also running (go to System Preferences... Sharing... Web Sharing). You can't have two apaches running at the same time, well, at least not glommed on the same default port 80. Hope this helps.

Re: [mapserver-users] time enabled WMS with video/ elements instead of img/ elements
Tim, (top posting because I have a more generic response) I have tackled this very much like you did with multiple images and opacity, etc. I too considered a movie, but the problem with a movie is that you can't zoom in. The images are geo-referenced, so you can zoom in and out and pan and drag. I was using OpenLayers, so I created a scrubber (a jQuery slider) and tied it to layer loading and unloading. I would query for an image and draw it only if the user moved slider to request a specific image. It was not very smooth, but it did work. You can decrease the weight of the images by using GIFs, at least, that is what I did. I remember I had 100 images (one for each year for a century's worth of model run) and the performance was quite good. I did pre-calculate the images at different zoom levels -- I believe there were 12 zoom levels, so I generated 1200 images and then used OL's layer image type. Wish it were possible to zoom, pan, drag a movie as if it were a map. On Jan 11, 2012, at 8:10 PM, Tim-Hinnerk Heuer wrote: Hi, Interested in HTML5 + MapServer and visualisation, read on. Happy new year to you all! I'm working on a rather interesting project at the moment where we need to map data over time. We tried experimenting with having one layer for each time unit and essentially overlaying them, manipulating their opacity to have a mini movie, but we noticed that the downloads of all the images become quite significant (61MB for a test extent!). I then implemented a proof of concept page (HTML5) where I took an extent's images and concatenated them in a webm video over time and then played all the videos at the same time, giving me a nice visualisation of that area at a relatively low cost (2.3MB per that extent) and the advantage of streaming. I have already written a script that generates all the videos, so I have invested considerable amounts of time into this. It would be great now if I could use the Apache module mapcache to serve up these videos listening and responding to WMS requests. So, all I need to change about mapcache is to serve a .webm file with MIME type video/webm instead of a .png file at the given extent. I guess I could write something in PHP or even with MapScript to serve up those files, but A) I don't know how mapcache finds the right image for an extent and B) Although I know C, my knowledge of it is a bit rusty and I don't know the interface(s) for writing Apache modules in C, let alone a plugin for mapcache I'm keen on learning, but if someone knows where in the code I would have to look for this change/feature enhancement it would be really helpful. Has something like that been done already or is in experiment/planning? If you could give me some hints of how to approach this in the quickest way possible I would be very grateful. Of course this is a project which needs to be done quickly but I want to do it anyway, because it's fun. Thanks for reading and hopefully you have an answer!

Works quite well, which makes me want to do the following -- 1. Have gdallocationinfo be aware of the NODATA value in the data set so it returns something predictable such as NO DATA or or whatver. 2. Currently gdallocationinfo queries only a point.

Use something like jQuery (my Js weapon of choice) to construct an ajax query. A JSONP query requires just one additional letter P. 2. Use a proxy. Remember, a few days ago I was asking about how to specify different classes in the browser address bar (in the URI) and use that to specify which classes are rendered by MapServer? I solved that by using a proxy... just a couple of lines of Perl, and that was solved. A bonus hint -- if your data are in Pg, don't even bother with getFeatureInfo.

David, On Oct 27, 2011, at 11:19 AM, Fawcett, David (MPCA) wrote: Two hackish thoughts: 1. Utilize a pair of mapfiles. The first one has all of the classes on by default. The second one has all of the class with STATUS OFF. On the client side, you determine if you have any class args and route the request to the appropriate mapfile. If the client has a request with class args, you append one of these for each class 'map.layer[0].class[3]=status on' (specifying the correct layer and class index values) The mapserver request is being made in a number of ways. If there is control on the client side, then, yes, different map files can be requested. http://server/mapall returns all the classes, and http://server/mapfew?class=Foo,Bar returns only Foo and Bar However, the same URI is to be reused in other client apps as well (such as OL), so the ability to choose which map file to request is limited. In any case, for a number of external reasons, the URI is supposed to be unique, so http://server/mapall and http://server/mapfew violate that principle, however, http://server/mapthem (defaulting to 'class=All') and http://server/mapthem?class=Foo,Bar do not violate that uniqueness principle. Alright, moving on ... If you only had a few classes, you could easily manage this with one mapfile (without running up against the character limits on GET requests) I said earlier that I have 100s of classes. I was wrong. Turns out I have 49 classes in this map file. However, in another map file I do have almost 700 classes. The use case is either the user gets all, or is able to specify one or two to filter and show only those. 2. What are you really trying to do? It seem like classes are for selecting and symbolizing/formatting data for output. Do you really want to filter out the data using a filter at the layer level. If you can avoid running all of your data through the expressions for each class, it should perform better too. Dunno how else to explain but with the following text -- the table (aka a layer) has a column called classes and these classes map to specific colors stored in another column.

So the dummy condition is passed when no filter is specified.
Believe it or not, I thought up of the above solution myself but discarded it
because I understood the text in the documents to mean the following --
FILTER class = '%class%'
will be applied if a class is provided. However, if no class is provided, and
if the following is provided

Then the filter will become class = '1=1', which is, of course not correct.

Re: [mapserver-users] default values if not provided in the URL

I guess I get around that by passing class=1 as my filter so I can pass

Hmmm... I didn't understand the above at all, but...
If you want to set a default that gets all, perhaps you could use a like
filter
FILTER Class like %class%
And a default of %
The suggestion above works quite well. Here is what I did
FILTER class LIKE '%%class%%'
METADATA
'class_validation_pattern' '^[a-zA-Z ]+$'
'default_class' '%'
END
So, now I can do http://server/app and get everything. Or, request
http://server/app?class=Foo and get a map with just Foo.
Now, the next problem to solve is to allow giving multiple class(es) as in
http://server/app?class=Foo,Bar,Baz
The only way I can think is to modify the filter like so
FILTER class IN (%class%)
which will allow me to pass values via
http://server/app?class='Foo','Bar'
but then I won't be able to get all the class(es). Besides, gosh, that URI
looks super ugly.
Thoughts? Maybe the cgi interface is malleable only to a degree. After that I
have to start thinking of other ways of solving this.
So, here is what I am thinking -- insert a proxy in between. That would allow
me to let the user formulate queries any which way I want, and then reformat
those queries to the way mapserver expect them. Of course, this proxy would
have to sit between mapserver and the rest of the apps, which in my world
includes OpenLayers.
Would love any directions and suggestions to tackle this.

Punnet,

So the dummy condition is passed when no filter is specified.
Believe it or not, I thought up of the above solution myself but
discarded it because I understood the text in the documents to mean the
following --
FILTER class = '%class%'
will be applied if a class is provided. However, if no class is provided,
and if the following is provided
METADATA
default_class 1=1

Then the filter will become class = '1=1', which is, of course not
correct. And, I just checked the logs with the above mods, and my
suspicion was proven correct. My log file shows ms croaking with the
following
select class,encode(ST_AsBinary(ST_Force_2D(the_geoms),'NDR'),'hex')
as geom,gid from table where the_geoms

the fine manual says http://mapserver.org/cgi/runsub.html
Since version 5.6, you can provide a default value for any
substitution
parameter, that will be applied if the parameter was not found in the
url.
You do this by providing special entries inside the layer metadata :
METADATA
'default_sound' 'yes'
'default_nseats' '5'
'default_multimedia' 'yes'
END
In this example, the mapfile will be created as if the url contained
³sound=yesnseats=5multimedia=yes²
Right then. Except, I want *all* my classes to be drawn if no class has
been provided. And, if one or more classes have been provided, then I
want only those to be drawn. So,
http://server/mapfile?mode=map
should return a map with all the 100+ classes in a layer. And
http://server/mapfile?mode=mapclasses=Foo,Bar
(or some other variation of the above) should return a map with only
the
requested classes in the layer. I can't think of anyway of doing the
above without resorting to scripting, and I still have had no luck with
WMS returned from Perl MapScripting.
Suggestions.

Re: [mapserver-users] arrow head doesn't draw at the end
Hi luis, Thanks for helping out. I will try OVERLAYSYMBOL, but from the docs it seems it is no different that using two stacked symbols. I did try GAP, but that doesn't help at all. As I mentioned below, I am drawing these points, not unlike the recent thread started by Brent on drawing wind barbs. Except, in my case, these are GPS sensor readings. The reading values are always 0 or more (actually, they are close to 0, but let's say, the really tiny ones are identifiable). The readings have two values... rate and azimuth. The length of the arrows has to be drawn proportional to the rate, and arrows have to be pointed toward the azimuth. First, I don't want arrows on the 0 (or, close to 0) readings but I still want to show them. So, I've decided I will just select them out and draw them as a separate layer with just dots. Easy. Now, the ones that are to be drawn with an arrow: the problem I am facing is that I want the arrow head at the end of the arrow stem that is of a non-predictable length.

Now it makes crystal clear sense. Nevertheless, consider that until as of this moment, I did take the docs to imply that the geometry in this case was the geometry of the symbol. When I say imply, I am not accusing anyone of misleading. I am asserting that the way a truth has been stated in the document can and has appeared as another truth to someone else. Just changing the docs to what you explained above would be fantastic. Additionally, per Havard, GEOMTRANSFORM apparently doesn't even apply to POINTs. Which now makes sense, since a point geometry's start, middle and end are exactly the same. However, again, stating this in the docs would be super helpful. Seems to me the *only* reasonable way to achieve this would be to have a GEOMTRANSFORM kind of capability for POINT layers as well, so that the last (or first or whatever... the specified) point of the symbol geometry could be decorated with another symbol. again, geomtransform applies to the underlying feature, not the symbol you are rendering on top of the feature. geomtransform will not help in your case. as paul suggested, you need to classify your data with a different symbol depending on your [rate], and use the azimuth for the orientation. Hmmm I am trying to figure out which Paul suggested where in this thread. Perhaps you are referring to the wind barb thread. In any case, I am not sure what you mean by classify your data with a different symbol depending on your [rate]. The way I am understanding that sentence is that I should have an actual different symbol for every different rate. Well, that will not only not work for me, it would defeat the purpose of all this automation. I have ~3000 points, each with a different rate. I can't possibly have 3000 symbols. Not just that, these rates change on a daily basis. Background -- these are readings from almost 3000 stations around the world reporting the rates daily. I get new values on a daily basis, so every day I would have a different map. (actually, it is a lot more complicated than that, but that is a good depiction of the problem). Many thanks again for your assistance, but I hope the above clarifies the issues. I am open to all kinds of suggestions at this point.

Maybe I should concentrate on trying to get WMS via MapScript working again so I can work within the more familiar and comfy environs of the Perl DBI. MapServer is fast as heck and basically joy to the world, but its Pg interface is a foreign world to me. This should help from the mapserver side of things. In the OpenLayers side of things you will need to propagate the parameter values into the base URL for the WMS request and get OpenLayers to propagate that change into the layer object. I see. Thanks for answering this, because this too had me stumped. The so called optional JS object that was supposed to pass arbitrary parameters to the OL layer constructor wasn't bringing any success. So, essentially, I should construct the base URL and then make my WMS layer as usual. If you expect the existing map to change when you change the values, then you will need to force OpenLayers to redraw the layer to request a new image or tiles based on the updated parameters. Yeah, of course. The idea is that the user clicks on the map, and based on the location of the click, a new map layer is generated. Hopefully I will have this all working soon and be able to show it to the world. Many thanks Steve (and you too Jukka).

If I call my template template.html I get the output, but I get mime type
warning and a syntax error in parsing the output.
The above is now partially solved. I still get the mime type incorrectly set,
but the syntax error was my mistake. However, it is something worthy of being
documented. I was making a JSONP (cross-domain) call. Hence, the response
coming back should have been wrapped in the callback as an argument. Since I am
stuck using CGI for now, I don't know if I can get MapServer to recognize the
callback param that is randomly generated by jQuery, and use that in the
template. So, I prescribed a custom callback, and used that in the template.
Before (doesn't work with JSONP)
-
$.ajax({
url : url,
type: GET,
data: ,
dataType: jsonp,
error : function() { alert(Error loading html document); },
success : function(r) { .. }
});
// mapserver template
{gid:[gid],unit:[unit_abbre],rock

msQueryByPoint(): Search returned no results. No matching record(s) found.
/BODY/HTML
Well, that gums up the works. I really want MapServer to just send an empty
JSON structure, something like foo({}). Suggestions on how I can prevent this
HTML message from MapServer, and force it to use the template instead?
If I rename the template template.json MapServer complains that the name is
malformed.
This one is interesting. Per Steve Lime's email earlier today, Issue 1: only
certain extensions can be used for templates. I believe .js is legal but .json
is not. We could change that in future releases. Could you file a ticket? Yet,
the docs at [http://mapserver.org/output/template_output.html] very clearly
mention the use of .json as a file extension. I quote
OUTPUTFORMAT
NAME geojson
DRIVER TEMPLATE
FORMATOPTION FILE=myTemplate.json
END
Fwiw, I using `NAME geojson` as above in my `OUTPUTFORMAT` block, but I am
returning just plain vanilla JSON. If I change the NAME to json, I get back
an unprocessed template.
If I rename the template template.js MapServer complains that it is Unable
to access file
.js being legal notwithstanding, the fact is, if I change my template.html to
template.js, MapServer errors with the above complaint Unable to access file,
whatever that means. Exactly the same file, same file mode, everything
identical, just the name change.
If I add `qformat=geojson` to my query (as shown in the link above), the
output contains the template with the place holders, no substitutions with
the values.
This is even more bizarre -- per the email thread at
[[http://osgeo-org.1803224.n2.nabble.com/GeoJSON-output-from-MapServer-td3188987.html],
it seems from Steve's comment that `qformat=geojson` is a valid query param
(although I don't see it documented anywhere). Yet, if I add that, I get an
unprocessed template.
What gives?

Puneet,
I'm doing pretty much that here:

I'm using jQuery in this example and putting the info into a jQuery
dialog, however I have used a standard browser window in the past.
Only thing is that I don't thinnk you really need step 0, simply
replace the contents of the container with the new info.
Yup, I don't have to worry about #0. Howerver, #1 above is problematic, and I
don't have a resolution for it yet. Seems like in Google Maps API v3 I can't
addListener to an ImageMapType overlay. See, I am adding a MapServer layer as
ImageMapType overlay like so
mapserverLayer : new google.maps.ImageMapType({ .. })
map.overlayMapTypes.insertAt(0, mapserverLayer);
If I do the following --
google.maps.event.addListener(map, click, function (event) { }
it works, however, the following doesn't work at all
google.maps.event.addListener(mapserverLayer, click, function (event) { }
Which is silly, isn't it? I don't want the entire map to be listening to the
click events. I just want the MapServer layer to be doing so. Haven't yet
found a resolution to this.
Also, if your data is in PostGIS you can skip mapserver for attribute
queries and do an info query against the PostGIS db via PHP or other

Ok, I am very interested in the above, but I am not sure I understand you. For
the most part, I want to click on the map, and find out more about what I
clicked on. In order to do that query via Perl MapScript (I don't know PHP) and
Pg, I would need to create the $mapObj. I am able to do that fine, but I don't
know how to run MapServer in `mode=tile` via MapScript. This is the question I
have asked a couple of times -- if I have a pure MapScript app (no map files
involved at all, which is what I want), how no earth do I tell the app to use
`mode=tile`?

[mapserver-users] bad query result crashes Perl
I query Pg to grab the data with which I construct LAYER CLASSes like so (nothing fancy).

Re: [mapserver-users] layer data sources more than one

I want a map showing the whole country's suburb boundaries. That's can be done by defining several layers (one layer reads one shapefile) in one mapfile. But actually there are not conflicts between these shapefiles. So I want to know is there any way to define only one layer and read the data from all these shapefiles. I am pretty sure (but not 100%) that you can have only one data source per layer. That said, you could either combine all the shapefiles into a single countrywide shapefile, or you could create separate layers, and then create a layer group (I am pretty sure you can group the layers into one... its been a long time, and I am just coming back to MapServer, so check the docs). That way, all the different layers for different states will behave as if they are a single layer. From the docs -- GROUP [name] Name of a group that this layer belongs to. The group name can then be reference as a regular layer name in the template files, allowing to do things like turning on and off a group of layers at once.

Puneet,
I'm doing pretty much that here:
http://records.sublettewyo.com/mapserver/map.html
I'm using jQuery in this example and putting the info into a jQuery
dialog, however I have used a standard browser window in the past.
Only thing is that I don't thinnk you really need step 0, simply
replace the contents of the container with the new info.
Yup, I don't have to worry about #0. Howerver, #1 above is problematic, and
I don't have a resolution for it yet. Seems like in Google Maps API v3 I
can't addListener to an ImageMapType overlay. See, I am adding a MapServer
layer as ImageMapType overlay like so
mapserverLayer : new google.maps.ImageMapType({ .. })
map.overlayMapTypes.insertAt(0, mapserverLayer);
If I do the following --
google.maps.event.addListener(map, click, function (event) { }
it works, however, the following doesn't work at all
google.maps.event.addListener(mapserverLayer, click, function (event) { }
Which is silly, isn't it? I don't want the entire map to be listening to the
click events. I just want the MapServer layer to be doing so. Haven't yet
found a resolution to this.
Also, if your data is in PostGIS you can skip mapserver for attribute
queries and do an info query against the PostGIS db via PHP or other
server-side tool.

Puneet,
I do not know how to bind an infowindow.open() to a click event
listener on the MapServer layer (#1 above) because I do not use the
Google API. But using Perl, PHP or whatever it is easy to query a
PostGIS database, and even get GeoJSON back should you want to
highlight the selected object on the map.
I am using OpenLayers so I can easily convert the mouse click (or box)
to a real-world coordinate(s). I pass the point or box to a PHP page
which connects to a PostGIS db, does the query, and returns JSON. Does
that help? I'm not sure that I understand everything that you're doing
and maybe my approach is not appropriate in your case.
I am assuming you are using OL with MapServer WMS. If I could get MapServer WMS
(via MapScript) working, it would have been good, but after screwing around for
a day and a half unsuccessfully, I gave up (for now).
Then I tried `mode=tile` and it just worked. However, even that is not fully
satisfactory as it is not via MapScript. Without MapScript I am severely
hampered -- the complexity of the datasets makes for beastly map files. My map
file with just one data source is already almost 9000 lines long. In fact, I
generate the map file via MapScript, and then further tweak it by hand.
Even with WMS or tile mode, I will have to implement some kind of tile caching
either with tilecache or map proxy or some such to improve the performance.
However, since I am not using MapScript (even though I would prefer to), I
would have to implement both CGI and MapScript to do what you are suggesting
above -- CGI to display the map and MapScript to do the query.
For now, I have been able to get this clicky thing working -- I click on the
map, do a `mode=query` and display the result in an infowindow. That part is
working.
Ideally, I would like to have a single technology -- MapScript to generate the
maps that can be displayed via multiple front-ends -- OL, Gmaps, perhaps
Leaflet, and MapScript to query the attributes via clicks and selects on the
map. For now, I am

But my point was that you can do the query without mapserver at all if the data is in postgis. Use a server-side language such as Perl or PHP to pass the request to postgis, which can do a spatial query, and then Perl or PHP can format the result as JSON and return it to the page (via AJAX). On second reading, I now get what you are saying. Strange that it never occurred to me. Sounds very sensible, and I will implement it tomorrow. That way I can get away from CGI `mode=query` and its TEMPLATE-ing vagaries. Yes, my data are in Pg, so I can do all my querying with Perl. Wish I could do away with `mode=tile` and also get tiles back via MapScript. Then my solution would be complete. Thanks for this really useful hint (more like making me see the obvious that I was missing for some reason).

Might be able to avoid the pains of WMS completely.
However, it works great with MapServer CGI. What if I want to use MapScript?
In other words, instead of
var urlTemplate = 'http://localhost/cgi-bin/myapp?';
urlTemplate += 'layers=layer1 layer2';
urlTemplate += 'mode=tile';
urlTemplate += 'tilemode=gmap';
urlTemplate += 'tile={X}+{Y}+{Z}';
I have
var urlTemplate = 'http://localhost/myapp.cgi?';
urlTemplate += 'tile={X}+{Y}+{Z}';
and I add mode=tile and tilemode=gmap on the server side. My question is --
one, will the above work? and, how do I pass mode=tile and tilemode=gmap and
the tile={X}+{Y}+{Z} parameters to the program? I didn't see any MapScript
documentation for these parameters. I need to translate a call such as
[http://localhost/cgi-bin/myapp?layers=layer1mode=tiletilemode=gmaptile=30+46+7]
into a MapScript request.
