Re: [mapserver-users] Problem with attribute query, multiple attributes
Since OGR accesses the GDB via ESRI's API/Library, it may (should) take
advantage of attribute indexes built on the data with ArcMap.
You should make sure that the feature classes in the GDB have attribute indexes
on any column that you want to use as query criteria and that they have good
spatial indexes as well.
If you don't have access to ESRI tools, you will likely want to pre-process the
data by dumping it from the GDB to shapefiles or PostGIS, where you can create
all of the indexes that you need.
David.

Thanks Jeff. That link shows how to build an index on a shapefile. Is there
an equivalent for File GDB? I'm looking at the GDAL document for GDB now, not
seeing an index description.

I am trying to set up an attribute query for a large parcel dataset

exceeding the 30 second limit.
I am trying to query on the map_bk_lot and town attributes. I can
query on either one separately and get results, but I need to query on
both at the same time.
Here is my query expression:
$queryExp = ('[TOWN]' == '007-042') AND ('[TOWN]' == 'Acton'));
---Hardcoded for testing now, will eventually use variables
$pLayer-queryByAttributes(MAP_BK_LOT,$queryExp,MS_SINGLE);
Query statement
The data is in an ESRI File GDB. I am using MS4w 3.0.4m MapServer
6.0.2, MapScript 6.1 for PHP
One other thing worth mentioning- if I use a small subset of features
(such as a town), the query will work without timing out. But I'm no
longer convinced that dataset size is the problem since it will query
on one attribute.
Any ideas what's going wrong here?
A tip that might come in handy someday, if not in this case, could be to create
an attribute index on your vector field (see example in
http://www.gdal.org/ogr/drv_shapefile.html); I've done this before and it's
improved attribute queries in MapServer significantly. You can generate one
through an ogrinfo command with the sql switch.
Sorry I cannot provide exact FileGDB examples at the moment.

Re: [mapserver-users] SDE Connection
With earlier versions like 9.2, ESRI put the SDK install files out on their Web site. With some of the later versions, you need to have the install CDs. You didn't say what service pack version you are running with 9.2, but here is a page with the SDK for 9.2 sp2: http://support.esri.com/en/downloads/patches-servicepacks/view/productid/66/metaid/1269 If you are on a different version, Google found this page in about 5 seconds. You may also have an issue with supported platforms, they usually have a page listing supported Linux disros and versions. In the past, they have listed Red Hat, but not CentOS. That doesn't mean that it won't work, I just don't know. If this doesn't work, or doesn't perform well, you might want to think about a simple ESRI Python script that pulls the data out of the production SDE database and push it into a PostGIS database or even shapefiles for use by MapServer. You could script it to run on some set time period. David.

Re: [mapserver-users] retrieve map coordinates with different EPSG
I looked at the documentation because I haven't used in a while. The docs aren't clear, but seem to imply that MAPXY should return coordinates in the same spatial reference system as the layer that you are querying. I kind of think that they should be in the spatial reference system of the map. Either way, try setting the map projection to the SRS that you want to get the coordinates back in. You will also have to change the extent values.

Typically the SQL syntax is column in (a,b,c,d)
So based on this

would be problematic I think because your syntax is:
column in 'string'
Which is not valid. Also what is your validation for %ID_BASSIN%?
Is something like this? ^\([0-9]+(,[0-9]+)*\)$
where ID_BASSIN=(123,234,345)

RE: [mapserver-users] Aligning labels within a polygon
Several years ago, I wrote some Python code to roughly georeference air photos. As part of that, I needed to come up with the best approximation of the heading of the airplane. What worked pretty well was to do a really simple line fitting based on the points. My samples were points from an airplane that was attempting to fly in a straight line, with vertices generated by a camera taking pictures at regular intervals, so that helped. I simply split the vertices of the line into three groups by dividing the total number of points by 3. I averaged the x and y values in each group and then created a line from the average coord from group1 to the average coord from group3. Street data will likely be more variable (curved), but you may want to explore something like this. Of course, you would likely want to calculate these label angles using pre-processing to speed up rendering time. David.

I don't think there's any more significant speed gain to expect now (at least on OGR side). Actually, I found a new improvement (committed in http://trac.osgeo.org/gdal/changeset/23946) that make the query time go down to 0.07 sec (*) ! There was a slowness when opening the layer due to the presence of an ORDER BY clause in the DATA string, that was evaluated before setting the spatial filter. (*) For comparison, I translated your database to Postgis, and set-up the connection mapfile to use that Postgis database (still through OGR, not the MapServer Postgis backend). The same request with OGR PG is run in 0.18 sec. Awesome! About 25 times faster in the evening than it was in the morning. My opinion is that because Spatialite seems to be, at least in this case, more that two times faster backend for Mapserver than PostGIS it should lead to some intensive and controlled testing now. I updated the cgi-bin directory of my MS4W 3.0.4beta1 with the mapserv.exe and dll files taken from the brand new binaries from http://www.gisinternals.com/sdk/ (contains Mapserver and GDAL revisions r13144, r23972, respectively). As a result Mapserver is really serving me 10, or 25 or even 40 times faster than it did before the update measured as WMS throughput (images/minute). The times include rendering times and all the lags in the system so the difference tells exactly how the end user feels it. Greatest enhancement is with close zooms because then the apatial index bites hardest. And at least with my computer Spatialite backend is clearly faster than PostGIS with the same data and it may be even faster than shapefiles but it is too early to say that really. But this is absolutely something worth more testing. My test database is moderately sized and contains 10 points, 9 lines and 149000 polygons from OpenStreetMap data. I will myself do next trials with ten times bigger Spatialite database with something like million points, lines, and polygons. We do not have much bigger tables in our production. However, I do not believe we are changing from Oracle to SQLite/Spatialite very rapidly in our core business :) -Jukka Rahkonen- ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

RE: [mapserver-users] Shapefiles not rendered
Juan, The projection block at the map level specifies 4326 as the spatial reference system, but the units of your extent look like they are in meters, not decimal degrees. This may be involved in the issue, or maybe not, but it would screw up a regular MapServer CGI request if you don't specify a bbox. The use of a '.' Character in a layer name may be valid in MapServer and the OGC WMS spec, but it looks funky to me. Again, probably not the problem. I would simplify your map file by commenting out the MINSCALE, MAXSCALE, and TRANSPARENCY lines. I am guessing that one of these is causing your problem. David.

RE: [mapserver-users] ticket for 'trimlast'?
Steve Lime has narrowed this bug down to the parsing of single quotes in
template tags.
The trimlast functionality will work if you use double quotes on the character
to be trimmed.
e.g.
This works: [feature trimlast=,]
This doesn't: [feature trimlast=',']
I will file a ticket for a change in the documentation at:

RE: [mapserver-users] default values if not provided in the URL
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) 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) 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.

RE: [mapserver-users] MapScript WMS request
Puneet,
Using MapServer CGI and layer.MapServer would not set you up well for other
client libraries, so I see your point. It can be viable though.
In this app (just an imagemap, not OL), there are no attribute values
associated with the spatial data. The classes are generated on-the-fly and the
county id's for each class are passed in as URL vars. Same thing for the
legend. This allows flexibility for compounds who's emissions may vary from
tens of pounds to millions of pounds.
This approach may not work for your case, but it is another way to slice it...

Possibly. See, it is crucially important for me to be able to generate classes
on the fly, and with a lot of flexibility. Not just that, the criteria for
generating the classes can change. So, what I am doing actually is setting up a
separate application that does nothing but respond with class information. The
mapping application (and, any other application, for that matter), would query
this class generating application and make the classes as per the latest
information. Hence, my need for MapScripting. Well, there are other reasons as
well, but this is an important one.

Now I see that although my map file specifies a map size of 640 x 480 pixels, if in single tile mode the map image being produced is actually 1110 x 660 pixels. Alternatively with multiple tiles I get 12 tiles of 250 x 250 pixels which is 1024 x 768 pixels.

Hi Ian,
In postgis there is an aggregrate function makeline() that you can feed
points to. I think there may be an equivalent function in SpatiaLite.
In sqlite, you might be able to use a group_concat() something like:
select 'LINESTRING('|| group_concat(lat||' '||long, ',') ||')'
from points;
But I think the issue will be that this is not a format that mapserver
understands. You might be able to access this via GDAL/OGR but I'm not
sure on that.

Because your data is not in the same projection, you will need to define a projection block in each layer section. Those projection blocks define the 'input' projection.

RE: [mapserver-users] capability to reproject to 2 different projections within the map object of the map file
I believe that in CGI mode, you can only have one output projection, so your approach won't work. You can support multiple SRS/projection in WMS mode. To do this, you put multiple SRS codes in the wms_srs metadata for a layer.

RE: [mapserver-users] DATA and SUBSET keywords
Stephan, This might be some newer syntax that I haven’t seen before, but I would try it a different way: DATA “'locaux_etj6_poly” FILTER (“[unite]” == “SCTA” AND “[dur_occ]” == “permanent”) Note: This is no longer using LIKE, but because you didn’t have any wildcards in your original expression, I am guessing that you just wanted the exact values. I am not aware of a ‘LIKE’ comparison in MapServer logical expressions, but you could definitely cook up a regular expression if you needed one. You don’t want to use the ‘smart quotes’ like my email client inserted. Just use plain double quotes. Case sensitivity may apply to the column names, it will definitely apply to the values. David.

RE: [mapserver-users] Mapserver Google Maps
Rashad, The short answer is, you can't do it. (That might be the long answer too.) From a technical standpoint MapServer can't consume tiles directly from Google and from a legal standpoint, when you accept Google's terms of service, you agree to not do something like this. If you want to display your own personal data with Google's data, do it on the client side. Most people do it using OpenLayers. David.

RE: [mapserver-users] OGR data layer type - points and lines
It took 4 whole days, but thanks to Sandro, Spatialite now has a MakeLine()
function.
http://groups.google.com/group/spatialite-users/browse_thread/thread/20f8e907ae9226
The feature is in SVN, I am not sure if it will make it into the pending 2.4.0
release. I am also not sure how the OGR driver works and if it can accept
geometries created on-the-fly, or if they need to come from a geometry column.

Ian,
I thought that there was a pretty simple answer to this, but it seems as though
I have imagined some non-existing functionality.
Assuming that you have a Spatialite db containing a point data set, and you
have a MapServer layer that draws this, I think that I have a solution for you.
(This also assumes that OGR supports reading linestrings from Spatialite).
PostGIS has the ST_MakeLine() function that allows you to create linestrings
out of point geometries. The current version of Spatialite doesn't have
anything like this (although since I have mentioned it on the Spatialite list,
it could be there soon...)
So, this SQL employs some workarounds, but may work:
SELECT LineFromText('LINESTRING(' || group_concat(X(geometry) || ' ' ||
Y(geometry), ',') || ')') FROM datapoints ORDER BY fix_date;
If performance is a problem, I would build a Spatialite line dataset and
rebuild it every time your point dataset changes.

I do not believe that this is possible.
If you want to draw lines you have to create a data source the returns
lines not points.
The problem is that mapserver draws features and each point is a
feature. It does not have a mechanism that can read a data source and
aggregate the point features into a single line feature.
I have seen posts on the PostGIS list for SQL that can do this. You
might ask on the GDAL list if there is a way to do this. Or if you can
use PostGIS, then you can find the SQL in the archives or ask again.

RE: [mapserver-users] OGR data layer type - points and lines
I guess I spoke a little too soon...
When I attempted to test this data definition, I got a mapserv.exe crash. I am
using a recent version of MSW4.
Also, in looking a little bit at the OGR driver page for sqlite:
http://www.gdal.org/ogr/drv_sqlite.html,
I am guessing that the driver can't use spatialite's native binary geometry
storage format when it is used to build a geom on the fly. Based on that, I
think that creating a wkt geom may be the way to go. Something like this
(which still crashes mapserv.exe).
DATA select 'LINESTRING(' || group_concat(X(geometry) || ' ' || Y(geometry),
',') || ')' AS wkt_geometry from turtle_points
This sample is also very simple in that the line vertices aren't being ordered
and the assumption is that you want one line from all of the points in your
dataset.

Steve, I need to do some more testing before I can report a bug. I have both OSGEO4W and MS4W installed on this machine and I was actually using the MapServer (5.4) from MS4W. I want to get a clean install and test before reporting this as a bug. I have a Spatialite point layer (turtle_points) that that draws using an OGR connection. In an attempt to simplify the problem of drawing a line layer that is generated on the fly, I tried to flop my point data to WKB and draw that. When I use this SQL for my data statement, I get a MapServer crash too. select AsBinary(geometry) from turtle_points I have playing with Spatialite for some time now, but hadn't yet combined my interests in MapServer and Spatialite.

RE: [mapserver-users] RE: Real life sample of a Mapfile for shp files on WMS
Matt, It looks like Steve Lime's regular expression example will get you what you are looking for. One strategy to think about with MapServer (and any other Web map server) is that when you are looking for the best performance, you want to pre-process your data as much as possible. This means pre-classifying your data if complicated expressions are necessary, projecting your data to get it all in the same spatial reference system, etc. MapServer can do on-the-fly projection, complicated expressions, etc. pretty efficiently. But, if you can do these tasks once in pre-processing, they won't have to be done every time someone makes a map request. In your case, if performance matters, I would consider creating a new column in your data source and splitting out the two 'tags'. An expression that is an exact string match will be faster than a more complicated expression.

RE: [mapserver-users] Real life sample of a Mapfile for shp files on WMS
Matt, It sounds like you have several different line layers and they are all currently being displayed in the default style (and that looks kind of crappy)... To make your data look better, you can use classes and styles within your layers. If you want all of the features within a layer to look the same, you just define one class within that layer. If you want to use different symbology based on an attribute of the data, you use multiple classes in the same layer. Individual classes have expressions that determine which features 'fall into' that class. Here is an example of a line layer with only one class. If you uncomment the first style, you 'stack' the styles and you get a colored line with an outline of a different color: LAYER NAME simple line TYPE LINE STATUS DEFAULT DATA 'rail_linesln3' CLASS #STYLE #WIDTH 6 #COLOR 120 120 120 #END STYLE WIDTH 4 COLOR 242 191 36 END END END In this case, if you had a column in your shapefile called ROAD_TYPE, you will get different symbology depending on the value of that column for that feature: LAYER NAME my roads TYPE LINE STATUS DEFAULT DATA 'roads' CLASSITEM ROAD_TYPE CLASS NAME 'Asphalt' EXPRESSION 'asphalt' STYLE WIDTH 6 COLOR 212 212 212 END END CLASS NAME 'Gravel' EXPRESSION 'gravel' STYLE WIDTH 4 COLOR 242 191 34 END END CLASS NAME 'Other' #any feature that doesn't match the above expressions gets caught by this class STYLE COLOR 255 51 51 WIDTH 3 END END Does this get you started?

We have got mapserver up and running, and the WMS is working fine. I have read through the documentation, but I am lost without an more detailed example of a mapfile. I have about 6 shp files. Each file has different features that I want to make into different WMS layers. The data is for a topographical map. For example a file contains roads, power-lines and walking tracks. Each type of road, power-line etc have different tags (some also have the name of the road after a comma). I am assuming this is fairly normal so far. What I want to be able to do is apply a different class (not sure this is the right term) to the roads, the power-lines and the walking tracks. Looks like I need to do some kind of query in the map file. At this stage we have only each file acting as layer. Does anyone have an example mapfile (that splits a SHP file into different layers) that they would be happy to send? I am fairly confident the penny will drop for me if I can see a working example.

RE: [mapserver-users] Tiger line file and mapserver
Adam,
There was a TIGER import into OSM, but many of the ways have been edited since
the original import.
From the display standpoint, the spatial reference system (SRS) of the input
data set is not very important. It is the output SRS that is important. I
think that you will want to set your output projection to world Mercator
(epsg:900913 or epsg:3785) http://spatialreference.org/ref/epsg/3785/
If you use 900913, make sure that there is an entry in your epsg database for
it, you may need to add it.
With MapServer, you can re-project on the fly, so your data doesn't need to be
in the output SRS, but you can make your map rendering more efficient by
pre-projecting the data to the output SRS.
David.

Subject: [mapserver-users] Tiger line file and mapserver
Hello everyone.
I'm having a problem with the Tiger line file in mapserver that I can't seem to
work out. I am using mapserver as my backend and openlayers as my frontend.
I'm not sure if my configuration is off, but I put on the layer in openlayers,
and the angle of the lines seems to be a bit off. If you look at, for
instance, openstreetmaps.orghttp://openstreetmaps.org (who also uses the
tiger file) in the area of new york city, all the blocks are perfect
rectangles. However, in my map, these same boxes seem to represent more of a
shape similar to a parallelogram with acute and obtuse angles at the corners.
I inspected the code of openstreetmaps.orghttp://openstreetmaps.org, and
looked at their openlayers code. They have something similar to this for their
map declaration:
map = new OpenLayers.Map('map', {
controls: [
new OpenLayers.Control.PanZoomBar()
],
units: m,
maxResolution: 156543.0339,
numZoomLevels: 20,
displayProjection: new OpenLayers.Projection(EPSG:4326)
});
I tried using this on my map (which also uses the tiger file), but I cannot get
it to scale properly. On the most zoomed in level, new york city is just a
tiny dot, and if I zoom out I can't see anything. Here is my mapfile code:
MAP

Does anyone see anything that might be the reason why I cannot get my map to

openstreetmap.orghttp://openstreetmap.org?

I looks like with gdal 1.7, spatialite support has improved. If you need to support layers based on queries that link geometry tables with attribute tables, spatialite could still potentially work. I haven't tested out a spatialite layer yet though. http://www.gdal.org/ogr/drv_sqlite.html there is also a new QGIS plugin that allows you to check data out of a PostGIS db and put it into a spatialite db.

Hi List,
I have several polygons in a postgis table. Some bigger polygons cover the
smaller ones.
How can I prevent bigger polygons drawn on smaller ones? On this case
smaller ones cant be seen only labels are drawn.
I don't know the problem is about drawing order but I think so.
As you can see on the screenshots, the small polygons can be seen but when I
zoom in some of them can't be drawn.
The images are purple because a bigger one covers all...
Thanks in advance..

RE: [mapserver-users] WMS Request for a single point?
Robert, This is an example of changing mapfile parameters via the request URL. It is documented on this page: http://mapserver.org/cgi/controls.html If Steve's example using 'mapsize' doesn't work, I would try 'map_size'. You are just setting/changing the values for the SIZE and EXTENT properties in the MapFile. See the documentation here: http://mapserver.org/mapfile/map.html Also, I haven't tested it, but you could try specifying the map extent, which it sounds like you want to set to the same extent (bbox) as your image. I would try something like map_extent=-97+43+-92+49 where the coords in the snippet match the bbox of your image. Note, you will want to make sure that the aspect ratio of your map_size matches the aspect ratio of your extent. If not, MapServer will adjust the extent to fill the image.

According to the docs, starting with MapServer 5.0, there is no limit to the number of layers in a mapfile. http://mapserver.org/introduction.html#layer-object I am guessing that you are running into a different issue. Have you captured the post request string and examined it to make sure that it is valid? Are you running into a string length limit for your post request? The URL for your post request would be limited to ~2k char for IE, but this only includes the URL to the server, not the key:value pairs. There could be a size limit for post requests set on your Web server to help prevent DOS attacks. I don't know where this would be set in IIS.

RE: [mapserver-users] Could not read data from MySQL database
I don't know if this applies to your case at all. In other cases where people have had mysql connections fail, it has sometimes been due to the lack of mysql support in ogr. One question to figure out is whether the ogr being used by MapServer is the same ogr that you are hitting when you run ogrinfo.

You can put the symbol definition in your map file, or in a symbols file (e.g. symbols.sym) and then set SYMBOLSET at the MAP level to point to your symbols.sym file.

RE: [mapserver-users] Dynamically draw different sized ellipses on map
It sounds like you really want to define polygons in an orthogonal projection and then re-project them to geographic to show the distortion. Unless you calculate the appropriate distortion for a particular coordinate and then can pass in the x and y radii for an ellipse symbol, I think that you will need to use polygon features instead of points. You have probably already seen the symbol construction page, but here it is: http://mapserver.org/mapfile/symbology/construction.html#sym-construction Matt Perry wrote kind of a cool example Python script that creates the kind of polygons that you are looking for. This won't work with the way that you are doing things, but it might give you some concepts and ideas. http://www.perrygeo.net/wordpress/?p=4 David. -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of stoli Sent: Tuesday, September 07, 2010 5:00 PM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] Dynamically draw different sized ellipses on map Was hoping on some guidance as to the best way to attack this... My app uses the cgi interface. I have been succesful at drawing lines, squares and small circles on the fly by sending mods to the .map file via the URL. I have been doing this by dynamically adding points to various POINT layers with the afforementioned symbols. Up to this point, the squares and circles have been uniform in size and aspect. Now I find myself needing to add multiple ellipses of varying sizes at different locations on the map. Technically they would be circles of area, but the aspect will change as the location approaches the poles. (almost a true circle at the equator and verly long ellipse toward the poles due to map projection). Ideally the ellipses will be filled with either a hatch pattern or a transparent solid color. Any suggestions as to the best way to accomplish this?

RE: [mapserver-users] RE: Dynamically draw different sized ellipses on map
I think that others will be able to answer this far better than I can. There are likely many ways to do this, it might help if you gave us a little bit more info about what you are doing. It sounds like the coordinates and area of the polys are determined on the client side and then need to be passed to the server for rendering? I do see an example in the comments to Matt's post where someone uses MapServer MapScript (in place of a CGI call) to build the data and add it to a dynamic map. It looks like they are writing out a shapefile and then using the shapefile as the source for a layer. I wonder if this might lead to unexpected results unless you can guarantee unique shapefile names for each map request. I believe that if you went the mapscript route, you could just build the poly features dynamically and use them in your layer without writing the features out to disk. I think that optimization will depend on your requirements. If a user starts a session, a data set is built, and then the client requests thousands of tiles based on those same features, there will likely be value in writing the features out to a shapefile or database. On the other hand, if the user hits a page and only one static map will be drawn based on the new unique features, there is likely no need to serialize the features.

Those are excellent references. I hadn't seen Matt Perry's site before. The Tissot Indicatrix certainly shows the distortion that I need to deal with due to map projection. I think I can work out the geometry of the ellipses. Assuming that the application needs to be capable of rendering up to 100 of these ellipses at varying locations at any given time, would you say the most efficient way to do this is to program the app to dynamically build a shape file and add it as a map layer each time a user requests the page, or create them as symbols (in which case I think I would need a different layer for each ellipse). I suppose I might run into URL length limits with the latter. Is there another possibility that I am missing? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Dynamically-draw-different-sized-ellipses-on-map-tp5508425p5511294.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
