Module Documentation: eml-spatialRaster
Back to EML Contents
The eml-spatialRaster module allows for the description of entities composed of rectangular grids of data values that are usually georeferenced to a portion of the earth's surface. Specific attributes of a spatial raster can be documented here including the spatial organization of the raster cells, the cell data values, and if derived via imaging sensors, characteristics about the image and its individual bands.

Element Definitions:

spatialRaster
Content of this field: Description of this field:
Type: SpatialRasterType
Attributes: Required?: Default Value:

Description:
Description of a gis layer composed of raster pixels comprising a regular-pattern grid. Generally, a raster object may be thought of as a pattern of closely spaced rows of dots that collectively form an image. Raster spatial objects are used to locate zero-, two-, or three-dimensional locations in the dataset
Example:
An interpolated grid of irregularly spaced data is an example of this element.
