Multiple GetFeatureInfo for Raster Data only returning results for one layer

Reported by: mdoyle Owned by: warmerdam
Priority: normal Milestone:
Component: WMS Server Version: 5.0
Severity: normal Keywords: getfeatureinfo raster data multiple

Description

When attempting to query more than one Raster data layer using GetFeatureInfo, the results only ever return information on the first layer in the list, never for the subsequent layers given in the LAYERS or QUERY_LAYERS parameter. FEATURE_COUNT is set to > 1.

Please find attached:
a streamlined map file: latest.map
two raster data files: rain_ann_tas.asc, rain_jan_tas.asc
two projection files: rain_ann_tas.prj, rain_jan_tas.prj

The data is a subset of Tasmania Australia only, to save on file size.

The URL used to reproduce this is as follows:
latest?&SERVICE=wms&VERSION=1.1.1&REQUEST=getfeatureinfo&LAYERS=rain_ann,rain_jan&QUERY_LAYERS=rain_ann,rain_jan&X=200&Y=150&INFO_FORMAT=text/plain&SRS=EPSG:4283&BBOX=144,-43,149,-40&FORMAT=image/png&WIDTH=400&HEIGHT=300&STYLES&FEATURE_COUNT=2

Example results are as follows:

GetFeatureInfo results:

Layer 'rain_ann'
  Feature 0: 
    x = '146.4625'
    y = '-41.4625'
    value_0 = '1116'
    value_list = '1116'
    class = '1000-1200 mm'
    red = '142'
    green = '206'
    blue = '165'
  Feature 1: 
    x = '146.4875'
    y = '-41.4625'
    value_0 = '1078'
    value_list = '1078'
    class = '1000-1200 mm'
    red = '142'
    green = '206'
    blue = '165'

I have modified the map (commenting out some unneeded stuff like fontsets, and symbol files), and I have run mapserv like this (note a few changes removing semi-colons from the reported url): 

mapserv QUERY_STRING='map=latest.map&SERVICE=wms&VERSION=1.1.1&REQUEST=getfeatureinfo&LAYERS=rain_ann,rain_jan&QUERY_LAYERS=rain_ann,rain_jan&X=200&Y=150&INFO_FORMAT=text/plain&SRS=EPSG:4283&BBOX=144,-43,149,-40&FORMAT=image/png&WIDTH=400&HEIGHT=300&STYLES&FEATURE_COUNT=2'

The result was as follows (in brief I got 15 responses for each of the two layers). This was done with a debug build of MapServer trunk on linux. I don't see any problem. I will attach the modified .map file and the supporting data as a zip (bug3586.zip) so that you can try them again at your end to see if you get the same results as I do.

Update: I installed MapServer 5.0.2 and the trunk version to test the bug with GetFeatureInfo on raster layers.

MapServer 5.0.2 produced the same result as our current version 5.0.0 erroneously producing results for only one layer.

The trunk correctly produced results for more than one layer, as seen above, but there were more records displayed than the feature count (a bug of which i have opened a separate ticket for at ​http://trac.osgeo.org/mapserver/ticket/2603).
