raster object |
The regular grid that represents a 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/pixel |
The cell in a raster object, which is also called a pixel. The data type of cells
can vary with the raster object, 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, which includes the spatial range, projection type,
and pixel type. The metadata of the remote sensing platform is not included.
