    v12 v13  
    3030'''ST_Accum(raster set|geometry set, ‘raster’|’geometry’) -> raster/geometry'''
    3131
    32 ----
    33 == '''Objective B02e - Being able to create on the fly and get data from registered (out-db) raster.''' ==
    34  
    3532
    36 '''Mostly change to Core API functions rt_band_get_data using GDAL to read from external raster.'''[[BR]]
    37 '''Add a ST_AddBand() SQL function '''[[BR]]
    38 Allow then to create, in SQL, a new out-db raster and to load it into the database:
    3933
    40 CREATE TABLE newIndbRastTable AS SELECT ST_AddBand(ST_NewRasterFromFile("c:/temp/myraster.tif"), "c:/temp/myraster.tif");
    41 
    42 and to tile it in a new table using a new easy to implement pl/PgSQL function using ST_Clip. No more need of gdal2wktraster.py to load a raster.
