[mapserver-users] Raster parameter PROCESSING BANDS=... and ECW files
Hi all I noticed a strange behaviour of MapServer (5.6.7 and 6.0.1) when defining for a raster layer based on an ECW file a processing parameter for the bands order like PROCESSING BANDS=3,2,1 The order of the bands does not have any effect. The image is always displayed in the original band order 1,2,3, whatever I define for the BANDS value. If I just define a single band, like BANDS=3 or BANDS=1 then it's displaying it correctly using the right band. This problem seems just to appear for ECW files, not e.g. for Tiff files. If I wrap a VRT image around the ECW and use this VRT in the DATA tag of the map file then the BANDS order is taken into account, just not when defining the DATA using the pure ECW file. Any ideas what's going wrong? Thanks for any hints Armin ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Any ideas what's going wrong? Armin, I suspect that the special interleaved read method in the GDAL ECW driver is not properly honouring the list of bands passed in to it. If this is the problem then it might not have come up with earlier mapserver versions that didn't do such reads in one interleaved request. If this is the issue then please test with GDAL trunk and if the problem persists file a ticket against GDAL.

[mapserver-users] Coloring vectordata by features/infos
Hello, I am rendering vectordata from a PostGIS database which works like a charm. My layer definition looks like this: LAYER NAME vector METADATA wms_include_items all wms_title dortmund_basic END TEMPLATE gfi.html TYPE POLYGON ## Should be inherited from MAP level, but is good practice to have here, too: ##(or not? .) #PROJECTION # init=epsg:900913 #END DUMP true CONNECTIONTYPE postgis CONNECTION host=x dbname=x user=x password=x port=5432 DATA the_geom FROM x CLASS STYLE COLOR 200 50 50 OUTLINECOLOR 60 60 60 #SYMBOL 0 ANTIALIAS true OPACITY 80 # in percent END END END Right now, I have not fully grasped how features/information is saved along with the vector data in the PostGIS database, but I am also not maintaining it. Supposingly we will have a float-value saved along with every vector. Can someone explain or give me hints, how I could map such a value which is saved along into a color? Like a brighter shade of red the higher the value is? Sincerely Michael Gajda ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

I tested the same configuration using the GDAL trunk from today and the problem persists. I filed a ticket for it on GDAL Trac (#4234).

Thank you for your reply. But I still don't know how to get extra information by using templates. Could you give me an example? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/WMS-getFeatureInfo-WFS-getFeature-tp6752411p6759479.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] google map
Is it possible that we can use google maps as a base map (for personal use - not for commercial applications). If we can, I need a sample of map file which shows configuration of google map layer in the map file. Appreciate your input Thanks -- Qazi M.
