Raster Data Summary
Raster Data is stored in Image objects
Raster Data content (i.e., pixel values) is accessed using specific Image-related functions in the Read and Write APIs
All Image objects in a transmittal are contained in the Image Library
Images may be geospecific or generic
- An Image can be mapped to a specific location to provide geospecific texture
- A Image can be reused many times to provide generic texture information
Image Mapping Functions are used to register Images to specific locations
Images can be associated with Features, Geometry, and Data Tables through Image Mapping Functions
Each Image object can have a complete set of supporting metadata
