Ticket #1318 (new enhancement)
[raster] Provide some predefined common usage userfunc for ST_MapAlgebraFctNgb
|Reported by:||pracine||Owned by:||pracine|
Now that we have ST_MapAlgebraFctNgb we might want to provide some predefined user functions like ST_Max, ST_Min, ST_Sum, ST_Distinct, ST_Mean, ST_StdDev, ST_Range, ST_Quantile, ST_Median, ST_Majority, ST_Minority, ST_Slope, ST_Aspect...
We might want to systematically change the prefix or add a suffix (I would suggest '4MA' i.e. 'for MapAlgebra?') to the function names so we know were written to be used with ST_MapAlgebraFctNgb. e.g. ST_Slope4MA()
