Description
The info resource returns information about the associated raster such as its width, height, number of bands, and pixel type.
The raster info resource supports ICS To Pixel. child resource. It returns geometric transformation coefficients that can be used to perform image coordinate system [sensor: Frame] to pixel (column, row) transformation.
The raster info resource supports the following child resources:
- Metadata Resource—Returns metadata for a raster catalog item.
- Raster Thumbnail—Returns a thumbnail for the associated raster.
- Raster Key Properties—Returns key properties for the associated raster.
- Raster ICS—Returns the image coordinate system for the associated raster.
