current, according to Vlad, wcst_import only can create GML for 2 types of coverage (RectifiedGrid? and RefererenceableGrid?). The problem is with non-georeferenced coverage like: mr, rgb or float_4d it will create GML for a coverage in RectifiedGrid?, which is not correct with the type of coverage's definitions:
+ GridCoverage: a regular, equispaced grid which is not spatially referenced (like a raster image which has no geo coordinates associated) + RectifiedGridCoverage: a regular, equispaced grid which is spatially referenced (like a satellite image which does have geo coordinates associated) + ReferenceableGridCoverage: a grid which is not necessarily equispaced (like satellite image time series where images do not arrive at regular time intervals, or curvilinear grids following river estuaries)
here is the compare between the RectifiedGrid? (mr) using by wcst_import and Grid (double_1d) using rasimport.
Vlad also proposed to have an option in ingredient file ("grid_coverage": true/false) then in wcst_import it can know where a coverage is GridCoverage? to generate correctly GML file.
