Unrelated to the original question, but: If by 'XML declaration', you mean 'XML prolog', it is not required to be included in XML. If you do not include one, the encoding typically defaults to UTF-8, however, which is likely a problem if you have iso-8859-1 encoded attribute data -- but since I don't think MapServer has any way of knowing the encoding of your data, including one probably doesn't help much anyway.

"An AJAX Tool for MapServer" is probably best solved by OpenLayers. http://openlayers.org/ The closest thing I can think of to 'flowing' in our examples is: http://openlayers.org/dev/examples/rotate-features.html But I know that others have done things like flight tracking with OpenLayers as well.

I've always just done this with TileCache:
http://crschmidt.net/blog/311/using-tilecache-with-google-maps-and-virtual-earth/
Do you really need WMS? It's possible, but I'd have to write some code,
and I'm very lazy :)

Open any modern OpenLayers page.
Open Firebug. (Or just open
http://openlayers.org/dev/examples/debug.html , which has firebug lite.)
Type the following:
new OpenLayers.LonLat(-71,42).transform(new
OpenLayers.Projection("EPSG:4326"), new
OpenLayers.Projection("EPSG:900913"));
Get result:
lon=-7903683.84523,lat=5160979.443331368

I don't mind you saying that, but the user should realize that when you
say "Should Be" you're not not instructing what he should actually be
doing in his current code, since the OpenLayers Library uses
OpenLayers.Projection, not OpenLayers.CS. (It also calls XYs "LonLat"s,
and many other similar mistaken naming choices.)
I'd recommend if you care about this issue, you should bring it up with
the OpenLayers development list, but I wouldn't bother; getting people
to undestand "Projection" is hard enough. (ANd why should it be CS
instead of CRS? or SRS? Or any number of other names that it could be
related to?)

You sound like you're using TileCache with metaTiling. TileCache sets
this property internally when using metaTiling.
I'm surprised you're seeing this though. The code says:
try:
# if the metadata is already set, don't override.
wms.getMetaData("labelcache_map_edge_buffer")
except mapscript._mapscript.MapServerError:
Perhaps turning debug off as suggested will get rid of this...
I don't know. But this is definitely directly related to TileCache.

Is it possible the difference is 'projections'? The Layer.MapServer in OpenLayers does not include any projection information, so if you have your OpenLayers Map configured in a way that would (via WMS) cause MapServer to reproject on the fly, it will have significantly different performance. (There are other side effects if your projections are actually different, but they might not be noticable at a first pass.) I agree with Steve that it probably makes sense to generate: * A WMS-served URL * A MapServer-served URL * Your mapfile configuration Those three things will probably help point towards the misconfiguration in your current setup.

There is a very obvious speed difference between the two. The reason the MapServer image has its colors wrong, for the record, is because it is using 8bit pngs instead of 24 bit pngs. My first impression was that was the reason for the difference, but unfortunately, 8bit gifs don't seem to fare any better.

Extend the MapServer documentation with a section for 'client development applications' or something similar. This section would be ideal for describing a number of suppoting applications to MapServer, such as TileCache, OpenLayers, GeoMose, and a small demo for each of those wouldn't be inappropriate if it can be done within a dozen or so lines of HTML in an ReST doc. 2. Add a general section with descriptions + pointers to other tools. This would be a less complete solutin than above, pointing to the GeoMoose site rather than documenting strongly its use within MapServer. 3. Work towards getting a MapServer gallery, similar to the existing OpenLayers Gallery, set up for MapServer/OSGeo. This i a task that Howard and I have discussed, but no serious work has been done on yet. This would allow you to share the GeoMoose demonstrations with more people. (Though I will note that every GeoMoose demo I've gone to in the past 6 months has been a pain for me, because I have to accept an expired security certificate... that might be worth fixing.) You seem to think that the curent demo on the MapServer homepage is a demonstration of OpenLayers, which I would disagree with strongly. It's entirely designed to be a demonstration of MapServer -- there is practically no UI or features of OpenLayers used, just a set of pretty Map tiles. If GeoMoose really creates a more compelling demonstration of *MapServer* functionality -- as opposed to GeoMoose functionality -- that a 'normal' user -- one without GIS experience, for example -- can appreciate, it might make more sense to have that be the case. Does GeoMoose use advanced features of MapServer that non-GIS users would be interested in? I haven't seen that thus far, personally, but would be glad to be wrong.

The MapServer homepage should be a quick, simple, easy to use demonstration of MapServer capabilties -- in this case, a pretty map. I can see an argument that the MapSerer homepage should use a static image instead, but I think that is a less effective demonstration of the pretty rendering.

This is a violation of the terms of use of Virtual Earth. If you have access to these tiles, the best way to access them would probably be to write a "WMS MiniDriver" in GDAL, Similar to the WorldWind and TileService plugins, that could access the VE tiles. The tiling scheme is relatively simple, and writing this code in GDAL would allow it to be used as a Layer within MapServer. I'm not aware of anyone having done this, because most people do not have legal access to the tiles. If you simply wish to combine MapServer data with VE data, you might look into OpenLayers.

This is incorrect.
Instead, what happens, is that when you request, A, B, or C, the 3x3
grid centered around B is rendered. when you request tile D, E, or F, the
3x3 grid around E is rendered.
In each case, a metaBuffer sized pixel boundary on all sides is created.
So, a 3x3 metaTile is actually 768 (3*256) + 20 (2 * 10) -> 788 pixels
big. This way, things near the edges of tiles are still included, and
you get fewer missed labels becasue the labels that san across the edges
of A and B are included, where they wouldn't have been before.

Binay, Generally speaking, OpenLayers talks to a URL to fetch 'tiles': images with data. This data can be provided by anything, so, for example, you can use PHP mapscript to accept image parameters and deliver this data. However, generally speaking, there isn't need to use MapScript for this type of application. Instead, you can use the MapServer CGI directly to serve requests, via WMS or some other mechanism. Whether you can use OpenLayers with your particular usage of MapScript depends entirely on how you're using it. Are you building an application in C# and want to use MapScript? Do you want to integrate OpenLayers in something that requests a dynamic image generated? Something else? All these possibilities have different sorts of answers. For a more detailed response than "Yes, but I don't know if you can", you'd need to share more details.

Both, but WMS is highly recommended, because using MapServer as CGI is prone to hide errors due to misconfiguration. (Setting up WMS requires only adding: metadata web wms_srs "EPSG:4326" end end to your mapfile to work minimally; everything else is optional.) The recovery map example has a significant amount of code, but it is using the trunk version of OpenLayers with no additional features. The UI, some of the popups, the layer addition/removal are all additional pieces added to that UI, but there are other toolkits (Like GeoExt) that provide these in open source software as well.

Many clients *can't* do this, and it does cause a problem for those clients. For example, it's difficult for qgis to consume Google Maps tiles, last I looked, but it can consume a WMS easily, so you can imagine using MapServer as the integration point. Web-based clients aren't the only types of clients that MapServer WMSes have, and are the only clients that can consume Google Maps. -- Christopher Schmidt MetaCarta ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

I guess I don't understand something... I thought GeoMoose was a web-based client. Most web-based clients should be able to consume Google Maps (as I said); But non-web based clients (generally) can't. (There are exceptions to this, even without violating the ToS, but they're the exception, rather than the rule.) Is GeoMoose a contradiction to that? Or is it instead just another web client that can consume Google Maps without violating the ToS?

This isn't strictly true. Desktop clients which are capable of embedding a browser can use the browser, render a scene, take the resulting image, and display that to the client. There are a number of clients which do exactly that in OpenStreetMap editors, for example. However, this is obviousl significantly more complex than just fetching the tiles, which is the way most people discuss doing it. Anything is possible, but that doesn't mean it will be easy.

The Google Maps static API doesn't let you pass in a bounding box, it lets you pas in a 'center and zoom'. The resulting tile will not always be centered exactly on that point such that it can be tiled, based on what I understand: Requests are still based around a grid, it's just not one that's obvious, iiuc. That said, I have no idea if this is within the Terms of Use. It also has other side effects; Google logo on each tile, etc. so it's not a great solution even if it does work, but would probably be better for desktop solutions which have a single view that they want to display data over, as I understand it.

His *mapfile* has 120 layers -- 40 of which are 'within range', 80 of which are not, and he's putting those 40 layers into one tile.

Yes. Typically you would have two "layers": One for your vectors, one for your satellite imagery. You would then turn them both on -- with the satellite being on the bottom -- and get 'hybrid' imagery. If you care about them actually being seperate images, you could serve them up on top of each other in a web interace: see http://openaerialmap.org/map/?zoom=4&lat=35.85938&lon=-87.53906&layers=BT for an example in OpenLayers.

I would say that the answer to this is "MapServer", in the same way tha the answer would similarly be "GDAL/OGR", "OpenLayers", and "KaMap" for those projects. (The last is the one in which I'd be most tempted to refer to it as "DM Solutions' KaMap", but I'd probably avoid it given the number of non-DM contributors.)

What is the form of "WHERE BBOX>"? How can I log this level of detail? You'll likely need to modify OGR to log this level of detail. In general, this type of logging is done by the 'server' in DB environments: Since SQLIte doesn't *have* a server, I don't think there's any way to do this external to OGR, and I don't believe that it's an existing feature of the OGR sqlite driver. In any case, MapServer is the wrong list for this: gdal-dev is probably the right place to go.

Re: [mapserver-users] MapServier and OpenLayers - with PHP?

1. '/wms/vmap0' doesn't use Mapscript, it uses MapServer as a CGI.
2. That path is a minimal CGI: it looks like:
{{{
#!/bin/sh
export MS_MAPFILE=/www/labs/map/vmap0.map
exec /usr/lib/cgi-bin/mapserv
}}}
There's nothing hidden here, it just makes the URL prettier. You can
equally do:
http://localhost/cgi-bin/mapserv?map=/www/labs/map/vmap0.map
instead.
> How would I get this to work with PHP, considering I can't get CGI to work?
I would suggest that getting CGI to work is likely to be a better path
than trying to write a WMS request handler in PHP. Perhaps you should
expand on why it doesn't work: you mentioned not being able to restart
Apache: is that something that a web host could help you resolve? Does
your web host allow you to run CGI executables?
