Re: [mapserver-users] WMS layer swapping according to scale
Hello Rahkonen, Thanks for answering so quickly. I had already proved that, but I had obtained a warning in the GetCapabilities request and I didn't have realized that it was working. Do you know how I can solve the warning?: Layer Namegroup/Name !-- WARNING: Mandatory metadata '..._GROUP_TITLE' was missing in this context. -- ... Layer queryable=1 opaque=0 cascaded=0 Namelayer1/Name ... /Layer Layer queryable=0 opaque=0 cascaded=0 Namelayer2/Name /Layer /Layer Also, I have read in http://www.mail-archive.com/mapserver-us...@lists.umn.edu/msg02321.html that there can be problems with the GetFeatureInfo query. ¿Does anyone know what these problems are? Thank you again for your help. -- Regards Gracia El día 9 de noviembre de 2010 10:39, Rahkonen Jukka jukka.rahko...@mmmtike.fi escribió: Hi, Layers cannot have a same name in WMS.

To do that, I have defined two layers in Mapserver to represent the same objects: one of them is a Polygon, and the other one is a Point (centroid), and I want to swap one for the other depending on the scale. With the Mapserver queries, I had defined the same name for both layers and it worked well. Now I need to do the same with WMS queries, but neither I can assign the same name to the layers (if I do that they are changed automatically), nor use the GROUP option (I obtain a warning with GetCapabilities). I also tried using the parameter wms_group_layer, but it puts a common title but not a common name, so I can not query the group in the LAYERS param. Do anyone knows how to solve this issue in Mapserver? Or do I have to do that in the viewer side?

Re: [mapserver-users] draw polygons ordered by field ? (from File System)
Hi, Sortshp can order data only by one attribute. If that is not enough you can sort shapefile by two or more attributes with ogr2ogr by giving ORDER BY inside the -sql parameter. Of course it is possible to split the shapefile into several layers by using FILTER. In that case the drawing order can be controlled by ordering the layers in the mapfile but perhaps you do not want many layers. However, if the result is to be used through WMS the layers can be combined back with GROUP. -Jukka Rahkonen- Bart van den Eijnden wrote: The only way I know of is to use the sortshp utility. http://mapserver.org/utilities/sortshp.html Best regards, Bart Hi All, Reading a shapefile (ESRI/MapInfo) from FS with polygons overlapping.

RE: [mapserver-users] RE: Real life sample of a Mapfile for shp files on WMS
Actually EXPRESSIONs can handle regex too: CLASSITEM ‘tag’ CLASS EXPRESSION /^TVOP2/ … END This catches all tag’s that begin with the pattern TVOP2. You might want to do a FILTER instead if this is the ONLY filter you need to apply. You’d see a small performance boost if that were the case.

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.

Wow Thanks guys, these where great examples, I got there straight away. Thanks for the advice on performance. This may become an issue, and sounds like it is better to deal with it early. This is a very powerful tool, with a great community base, I am very impressed Now of the fun part, making the maps look pretty :) Thanks again Matt :) -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Real-life-sample-of-a-Mapfile-for-shp-files-on-WMS-tp5718787p5722388.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
Re: [mapserver-users] WMS 1.3.0 questions
Hi, Have a try with EPSG:4326 and you should see a difference. Despite of axes flipping with some projections there should really not be any difference in the GetMap output - image is an image. Do GetCapabilities and you should see difference. I am remembering also that VERSION is a compulsory parameter in WMS GetMap so there is no need to play with the defaults, just give the version and you will get what you want. -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Yves Moisan Lähetetty: ti 9.11.2010 23:58 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] WMS 1.3.0 questions Hi All, I tried to look for an answer to the question what do I have to do to get MapServer to serve a 1.3.0 WMS by default and I haven't found yet. Is there anything to do in the mapfile per se or is it just by the virtue of having a version = 5.4 ?

Both images were the same, so I thought everything was fine until I tried an unexisting version number (e.g. 1.1.122) and still got back an image ! The only error message that made me think MS was indeed looking at the version number is when I submitted VERSION=abc. then MS complained it wanted x.y or x.y.z. So how can I tell I get a real WMS with my specified version number instead of what appears to be a default one ? Doc pointers appreciated.
