[mapserver-users] Get Pixel value of RASTER data using input geographic coordinate via WMS or WCS

[Sarawut Ninsawat]

Hi list,

I would like to get a raster pixel value using WMS or WCS connection. For
example, 1 pixel value from 10 Modis image band. The value may be returned
as xml or gml if possible.
I know we can use GetFeatureInfo via WMS to get a value of pixel (of vector
or raster). But the input x and y or is an image oriented not exactly
geographic coordinate value.
In case of WCS, GetCoverage allow to request data with a geographic
coordinate. But I used to familiar with outputformat as Image file. Is there
possible to use it and return as GML or text based?
Please advise me for some hint,
Sarawut
