I haven't done something similar to what you are trying to do, but at first glance i see a space standing between vector’ and END. Did you try replacing the space with %20? Just a thought :).

[mapserver-users] MyGIS problem after upgrading 5.2.1 - 5.6.5
Hello! I have read about MyGIS being deprecated, but I'm hoping for a quick fix for this particular problem, which wouldn't involve rewriting a lot of queries. We have a MyGIS layer which stopped working after upgrading Mapserver from 5.2.1 to 5.6.5. The data definition is: DATA 'geometry from (select * from koht where omavalitsus_id=-1) feature, koht_bin geometry' When this layer is accessed from PHP/Mapscript, the following errors are logged by PHP: [MapServer Error]: msQueryByPoint(): No matching record(s) found. in source_file.php on line 35 [MapServer Error]: msMYGISLayerGetShapeRandom(): GetShape called on MYGIS layer with invalid DB query results. in source_file.php on line 35 [MapServer Error]: SELECT feature.id, feature.vertices,geometry.WKB_GEOMETRY , fe: mysql query failed in source_file.php on line 35 [MapServer Error]: describe (select: mysql query failed in source_file.php on line 35 I turned on query logging in MySQL, and the log shows that the query being sent to MySQL is: describe (select which certainly *should* fail. It seems that if I use a subquery in data definition, DESCRIBE is being done only on first word of the subquery. If I replace the subquery with a table name, things do not break, but this way I can't get the result that I actually need. Can anyone suggest a workaround? -- Toomas Aas ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] problems with relative path in mapfile

[mapserver-users] Re: ‘mode=map’ with WMC of dynamic Layer failing with getString() error
That error usually occurs when there is a problem with the syntax of your CGI query string. That is consistent with the post I found at: http://osgeo-org.1803224.n2.nabble.com/Clarification-on-RFC-44-changes-td2585073.html which suggests that there may be a problem with the syntax of “map.layer[line]=DATA ‘id3/vector’ END” in my URL but I don’t know what an alternative correct way to send this information would be that would work for both the WMS GetMap requests and the “mode=map” method. I haven’t been able to get either the WMS GetMap request or the “mode=map” request to work trying to guess. Is there anyone out there who can provide any help with this? I have reviewed the URL Jeff provided and tried using an underscore rather than the dot notation but continue to receive the getString() error. Is there some alternative syntax to try for specifying the DATA parameter that would work for both a getMap request and using “mode=map”? I don't see anything else in my URL that could be wrong...but maybe I've been looking at it too long. Also, to respond to Ophidian, I have tried inserting %20 and '+' in the blanks and tried replacing the single quotes as shown below. All to no effect.

[mapserver-users] Re: ‘mode=map’ with WMC of dynamic Layer - Solved!
After preparing my last post, I noticed the strange numbers (really the fact that I got two different ones) for the single quotes when I encoded the URL (%91 and %92) that was failing: http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apps/testing/dynamic.mapmap.layer[line]=DATA%20%91id3/vector%92%20ENDlayers=linemode=map And, after looking closer, I realized there were smart rather than regular (as in %27) single quotes. Once I changed them the following URL worked fine in the browser after all: http://localhost/cgi-bin/mapserv.exe?map=/ms4w/apps/testing/dynamic.mapmap.layer[line]=DATA 'id3/vector' ENDlayers=linemode=map So, I thought, my attempts at trying to figure out what the bigger problem I was having had failed to this point. I did not have smart quotes in the WMC for that Layer definition (as shown in the original post) but I was unable to create an output image with it. Then, I thought of Obsidian's suggestion and changed the LayerListLayer definition as follows (see the blanks replaced with %20 in the OnlineResource values): Layer queryable=0 hidden=0 clid=id3vector Server service=OGC:WMS version=1.1.1 title=Id3 Vector OnlineResource xlink:type=simple xlink:href=http://domain/ogc/printVecWms_en?map.layer[line]=DATA%20'id3/vector'%20END/ /Server Nameline/Name Titleid3 vector/Title SRSEPSG:42304/SRS FormatList Format current=1image/png/Format /FormatList StyleList Style current=1 Namedefault/Name Titledefault/Title LegendURL format=image/png width=47 height=294 OnlineResource xlink:type=simple xlink:href=http://domain/ogc/printVecWms_en?version=1.1.1service=WMSrequest=GetLegendGraphicmap.layer[line]=DATA%20'id3/vector'%20ENDlayer=lineformat=image/pngSTYLE=default/ /LegendURL /Style /StyleList Extension ol:maxExtent minx=-2903297 miny=-789911 maxx=3431059 maxy=3959683/ ol:transparenttrue/ol:transparent ol:isBaseLayerfalse/ol:isBaseLayer ol:displayInLayerSwitchertrue/ol:displayInLayerSwitcher /Extension /Layer And, low and behold, I have an image with the dynamic shapefile's contents included.

[mapserver-users] Boundary overlay shift
Hello, I have been using Mapserver with Tilecache and Google maps to display polygon boundary overlays for some time now. However, the users complain that the overlay is not accurate if they zoom in to the map (zoom level 14 onwards). Is this a problem with the projection scheme being used? I think my data is in epsg 4326 format. What projection scheme does google maps use? Its strange that everything looks fine at the higher levels but when I zoom in beyond level 13, the boundary gets misaligned though the shape of the boundaries is accurate. Has anyone solved this problem? If yes, it would be great if you can point me in the correct direction. BTW, I use ms4w for windows and the GtileOverlay method with tilecache to render the boundary overlays.

Suggestion? You can use classes in your map file's layer declaration, where values within a certain range are given a color range, as in below: == ...

Using COLORRANGE will cut down significantly on the number of CLASS objects declared for your LAYER. Does this help? I hope I understand your problem correctly...

RE: [mapserver-users] get the closest feature in a point query
For mode=query (e.g. a standard point query) the closet feature is found. A layer's tolerance is used to select candidate features and then distances are computed for each candidate feature. If no feature is found in one layer then the process moves to the next layer. The computed distance doesn't persist across layers... Does this make sense or are you seeing something different?
