compare projections

Parameters

proj_info1
proj_units1
proj_info2
proj_units2

Returns

-1 if not the same projection, -2 if linear unit translation to meters fails, -4 if not the same ellipsoid, -5 if UTM zone differs, -6 if UTM hemisphere differs, -7 if false easting differs, -8 if false northing differs, else TRUE if projections match.

create a new location

This function creates a new location in the current database, initializes the projection, default window and current window.

Parameters

location_name	The name of the new location. Should not include the full path, the location will be created within the current database.
wind	Contains the default window setting for the new location. All fields should be set in this structure, and care should be taken to ensure that the proj/zone fields match the definition in the proj_info parameter (see G_set_cellhd_from_projinfo()).
proj_info	Projection definition suitable to write to the PROJ_INFO file, or NULL for PROJECTION_XY.
proj_units	Projection units suitable to write to the PROJ_UNITS file, or NULL.
report_file	File to which creation information should be written (can be stdout). Currently not used.

Returns

Returns 0 on success, or generates a fatal error on failure. The G__make_location() function operates the same, but returns a non-zero error code on failure, instead of terminating.
