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 IC
. 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.
