  1. ESRI User Conference 2004 Rasters

  2. Raster Loading • Loading options • Mosaic images into a raster dataset • cannot have overlap – it is eliminated • All must be of same properties and interpolation method. • Multiple raster datasets • One for each tile • Raster catalogs • overlap is kept • this is a collection of raster datasets • The SDE raster command line creates an 8.3 raster not a 9, therefore it has no geometry column. It must be registered

  3. Raster Loading (cont’d) • Steps to loading a large amount of raster data: • Configure your system • Create the DBMS storage space • Prepare the source data • Create a raster object • Load image data into the raster • Build statistics (DBMS) • Build statistics (Raster) • View (repeat above steps until it is right) • Transferring the data (if needed) • Do this thru detached files or SDEexport.

  4. Tips • Use Direct Connect if client is faster than server • Use Fillfactor of 95 to 100 if read only • Increase size of rasterbuffsize during load process (to 10 MB) • sdeconfig –o alter –v rasterbufsize = 1024000 … • Calculate stats • Pyramid reference point • important, because pyramids will be recreated if you are outside this • Load the upper left image first – it uses the min x, max y • Applying pyramids will increase storage space by about 33% • Pyramids are not used for analysis, but are used for printing

  5. Some New Stuff • Personal Geodatabases • Can have raster datasets now (sort of) • Only outlines are stored in the PGDB • Images are copied to an .img format file • Can have raster catalogs now • Managed • Image is stored locally as .img • If you delete the outline the image is deleted • Unmanaged • Image is not stored locally • Image is not deleted if you delete the outline

  6. More New Stuff • Raster Column • Feature classes can have one raster column defined now • The column definition will say Raster • The image must be loaded in an ArcMap session • Looks like it is only a link to the image • Attribute Column • Raster catalogs can now have attribute columns
