  1. Raster Data Management/Image Server

  2. 9.2 Additions/Changes to Raster Data Management • It is now possible to do orthorectification in ArcMap, image/raster must have RPC (rational polynomial coefficients) and you need a DEM • You can now generate a hillshade on the fly, without the need for the spatial analyst extension (check box in symbology tab) • Creation of Terrain dataset, used to store massive amounts of surface data. • TIN based • Must be stored in a Geodatabase dataset (personal, file, SDE) • 3D analyst is used to create a Terrain • You can generate a DEM from a Terrain and use it to perform different raster analysis functions

  3. Quick Facts on ArcGIS Image Server • Provides fast access to imagery • Sensor to server • Server to screen • Can read variety of different types • Reduces storage, by cutting down on redundancy • Imagery can be resampled on the fly, with Image Server there is no need to store grayscale and color imagery, or varrying levels of compression. • Compression for storage is independent from compression for transmission, client can control compression level to balance performance with image quality • Orthorectification, enhancement, and mosaicking can be performed with Image Server on the fly • Could mean quicker delivery of imagery to data partners • Seamlessly integrate rectified imagery with service once it is available

  4. Viewpoints, potential Oblique Imagery layers with Image Server • Image Server handles overlapping images with what they call viewpoints. • Viewpoints allow different views of the same location when overlapping imagery is present.
