The envelope (bounding box) contains two pairs of coordinates, one for the lower left coordinate and one for the upper right coordinate: +----------o Upper right; (max_x, max_y) | | | | | | Lower left (min_x, min_y) o----------+ iÿÿÿÿ(t Structuretc_double(t GDALExceptiont OGREnvelopecBs8eZdZdefdefdefdefgZRS(s'Represents the OGREnvelope C Structure.tMinXtMaxXtMinYtMaxY(t__name__t __module__t__doc__Rt_fields_(((sn/var/www/html/phendo-backend/phendo_python/env/lib/python2.7/site-packages/django/contrib/gis/gdal/envelope.pyRs    tEnvelopecBs³eZdZd„Zd„Zd„Zd„Zd„Zed„ƒZ ed„ƒZ ed„ƒZ ed „ƒZ ed „ƒZ ed „ƒZed „ƒZed „ƒZRS(s× The Envelope object is a C structure that contains the minimum and maximum X, Y coordinates for a rectangle bounding box.
