00005 <p>The Feature Data Objects (FDO) API provides access to data in a
00006 data store. A provider is a specific implementation of the FDO API
00007 that provides access to data in a particular data store. The Autodesk FDO Provider for Raster
00008 is a stand-alone file format that supports GIS data.
00009 </p>
00010
00011 <p>The FDO Provider for Raster has the following characteristics:
00012 </p>
00013 <ul>
00014 <li> The FDO Provider for Raster supports georeferenced file-based raster images and
00015 file-based grid coverages. Raster images are pixel-based images, such as digital
00016 photographs (satellite images, for example). Raster images
00017 are very useful as background images underneath your vector
00018 data, for example, an aerial photograph of a city with a
00019 layer of streets overlaying it.
00020 <li> The FDO Provider for Raster can run in a multi-platform
00021 environment, including Windows and Linux.
00022 </ul>
00023 <p>The following list shows the raster image file formats
00024 that are supported, along with their acronyms and file extensions:
00025 </p>
00026 <ul>
00027 <li> JPEG (.jpg, .jpeg) - Joint Photographic Experts Group
00028 <li> JPG2K (.jp2, .j2k) - Joint Photographic Experts Group
00029 <li> MrSID (.sid) - Multi-Resolution Seamless Image Database
00030 <li> PNG (.png) - Portable Network Graphic
00031 <li> TIFF (.tif, .tiff) - Tagged Image File Format
00032 <li> DEM (.dem) - USGS Format Digital Elevation Model
00033 <li> ECW (.ecw) - Enhanced Compressed Wavelet
00034 <li> DTED (.dt0, .dt1, dt2) - Digital Terrain Elevation Data
00035 <li> ESRI ASCII GRID (.asc) - ESRI Surface
00036 <li> ESRI Binary GRID (.adf) - ESRI Surface
00037 </ul>
00038 <p>The following data models are supported:

00130 <li> Only DEM, TIFF, and ECW images support the Data
00131 ModelType.
00132 <li> All 2- and 4-BitsPerPixel images are promoted to 8
00133 BitsPerPixel as per the underlying ATIL behavior.
