Description
Returns the pixel value of an image at a given x,y coordinate location for the specified layer.
Restrictions
- Valid with Image and ArcMap Server only.
- GeoTIFF is not valid with Image Services with this request. However, this format is valid with ArcMap Image Services.
- The following formats do not work on ArcMap Image Services on Solaris and UNIX: CADRG, CIB, Erdas Imagine, GeoTIFF, MrSID and TIFF (multiband). This is not a restriction on Windows.
- This request is not valid on feature layers.
Notes
- See RASTER_INFO for response.
- If COORDSYS is not included as a child element, it is assumed that the coordinates used for GET_RASTER_INFO x and y are in the same coordinate system as the raster image. If COORDSYS is used in the request, the attributes are in the coordinate system defined by COORDSYS.
- If an x,y coordinate is out of range, an ERROR message is returned instead of RASTER_INFO.
