|raster object||A regular grid that represents a defined space. Each cell in a raster object is assigned an attribute value to represent a data model of an entity. A raster object can be a satellite image, a digital elevation model (DEM), or a picture.|
|cell or pixel||The unit of measure of a raster object. A cell is also called a pixel. Each cell can have different data types, such as BYTE, SHORT, INTEGER, or DOUBLE.|
|band||The measure of a single characteristic of a raster object. A band is represented by a single matrix of cell values. A raster object can have one or more bands.|
|chunk||The portion of a raster object. The size of a chunk can be customized, such as 256 × 256 × 3.|
|pyramid||The downsampled version of a raster object. A pyramid can contain one or more downsampled layers. Consecutive pyramid layers are downsampled at a scale of 2:1. Layer 0 stores the raw data.|
|pyramid level||The layer in a pyramid.|
|mosaic||The operation to integrate one or more raster objects into an existing raster dataset.|
|interleaving||The arrangement of pixels in a raster object. The interleaving types include band sequential (BSQ), band interleaved by pixel (BIP), and band interleaved by line (BIL).|
|world space||The geographic coordinates of a raster object.|
|raster space||The pixel coordinates of a raster object. The top-left corner of the raster object is used as the starting point.|
|metadata||The metadata of a raster object, including the spatial range, projection type, and pixel type. The metadata of the remote sensing platform is not included.|
