[mapserver-users] How to use msQueryByPoint with RASTER

[darenas]

Hi Steve,

I tested GetFeatureInfo directly with the folowing sentence:

http://localhost/cgi-bin/prueba_grid?REQUEST=GetFeatureInfo&VERSION=1.1.0&SERVICE=WMS&QUERY_LAYERS=mapa_apicola&FEATURE_COUNT=1&X=521&Y=426&SRS=EPSG:25830&BBOX=462204.1344,4460380.45879,463515.19339,4461472.57092&WIDTH=1000&HEIGHT=833&LAYERS=mapa_apicola&STYLES=default&FORMAT=image/jpeg

and the response is the same: GetFeatureInfo results:  Search returned no
results.

TIFF file has an attribute table. I made a shot:

http://n2.nabble.com/file/n3188765/tiff.jpg 


That´s the layer code; maybe could be useful to guess the problem:


LAYER					 						# Comienzo del objeto LAYER
  NAME "mapa_apicola"        						# Nombre corto para la capa
  TYPE RASTER                  						#
[point/line/polygon/circle/annotation/raster/query] especifica como los
datos podrán ser dibujados
  STATUS ON                   						# [on/off/default] Establece el estado
de la capa
  #PROCESSING "SCALE_1=1,255" 
  #PROCESSING "SCALE_2=1,255" 
  #PROCESSING "SCALE_3=1,255"
  #PROCESSING "SCALE=AUTO"      						# Pasa un directorio de proceso que se
utilizará con esta capa 
  PROCESSING "DITHER=YES"    							# Pasa un directorio de proceso que se
utilizará con esta capa 
  #OFFSITE 0 0 0
  DEBUG OFF
  DUMP TRUE				 						# [true/false] Permite que Mapserver genere la
descarga en formato GML 
  
  
DATA "D:\TIFF\mapa_apicola.tif"

TEMPLATE "D:\ms4w\maps\etc\template.html"

Thanks a lot again
