int Header::categ

If not zero the map represents a categorical variable. This way it cannot be interpolated. Obs: it is not saved in files! (there is no room :( ).

Referenced by operator=(), and printHeader().

int Header::grid

"grid" (not zero) or "pixel" (zero) cell alignment

Definition at line 86 of file Header.hh.

Referenced by GdalRaster::open(), operator=(), and printHeader().

Coord Header::gt[6]

The actual gdal geotransform

Definition at line 80 of file Header.hh.

Referenced by convertLonLat2XY(), convertXY2LonLat(), GdalRaster::create(), Header(), GdalRaster::open(), operator=(), and printHeader().

int Header::minmax

If not zero 'min' and 'max' are valid values.
