Raster class final

Represents raster data that can be rendered using a RasterLayer.

A raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps.

A Raster can be created from a raster file on the device or from a RasterFunction.

Supported Raster formats include:

  • ASRP/USRP
  • CRF
  • DTED0, 1, 2
  • GeoTIFF
  • HFA
  • HRE
  • IMG
  • JPEG
  • JPEG 2000
  • MrSID, generations 2, 3, and 4
  • NITF
  • PNG
  • PDF
  • RPF (CIB)
  • RPF (CADRG)
  • SRTM1, 2
  • Mobile mosaic datasets
