Function Details

getExtentFromRectifiedDS(ds, eps=1e-06)

Calculates the extent tuple of the given gdal.Dataset. The dataset must be rectified, i.e. projected to a recognized CRS, and the geocoding must be encoded by the GDAL's Geo-Transformation matrix. The ``eps`` parameter is the relative threshold for non-zero values of non-diagonal terms of the GDAL's Geo-Transformation matrix.

getExtentFromReferenceableDS(ds)

Calculates the extent tuple of the given gdal.Dataset. The dataset must be encoded using the tie-points.
