Differentiate CRS:1 and IndexND in WCPS 1.5
|Reported by:||bphamhuu||Owned by:||bphamhuu|
In current WCPS 1.5, there was a misunderstand between CRS:1 and IndexND (e.g: rgb is a grid coverage with i and j axis and the grid CRS for the i and j is Index2D). This is not correct as the CRS:Index2D is consider as a geo-domain for i and j, meanwhile the CRS:1 is the CRS for every axis which want to query directly in the grid-domain of Rasql.
Another example is a coverage with an irregular axis (named: height is index1D) with value (0, 100, 300, 500, 700). Then i(100) is totally different with i:"CRS:1"(100), the former is valid, the latter is out of Rasql bound.
