RasterCatalog Class (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
A collection of raster datasets in a Geodatabase table.
The RasterCatalog was added at ArcGIS 9.0 and is only supported within Personal, File and ArcSDE Geodatabases. Similar to raster catalogs in previous releases, a RasterCatalog manages a set of related raster datasets; their footprints, names, metadata, and any other user defined attributes. Specifically, a RasterCatalog is a custom feature class containing a field of type Raster, and a predefined Shape field of type Geometry. Each raster dataset within a raster catalog corresponds to a feature.
The Raster field can have a spatial reference that is applied to all raster values if the raster itself have an unknown spatial reference, and it is defined using RasterDef. The Shape field stores the footprint of a raster value in a given target spatial reference (equal to the spatial reference of the Shape field). The footprint is automatically managed, populated and spatially indexed by the geodatabase.
The row objects handed out by a raster catalog support the IRow, IObject, IFeature and IRasterCatalogItem interfaces.
