Data/Sample, Pixel/Image and Compression Types

  • often needed for ['RL2_CreateRasterCoverage'] (RL2_CreateRasterCoverage)

[--> 'List of Sql-Commands'] (Home#commands)

[<-- 'Index Page for RasterLite2 - Commands'] (RasterLite2-Index#commands)

Tip:

When in doubt about:

  • under what conditions
    • who belongs to what
      • to be used where

Look into the sql-text of the

  • raster_coverages
    • BEFORE INSERT triggers

That is where all of these conditions are being inforced.

**Data/Sample Types**:
