<GET_RASTER_INFO	Attribute Description Table
When using ArcMap Server:      (r)layerid="string"      (r)x="double"      (r)y="double"      dataframe="string"      When using Image Server:      (r)layerid="string"      (r)x="double"      (r)y="double" >      <COORDSYS... /> </GET_RASTER_INFO >
(r): Attribute or child element is required.

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.

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.
