- database name for PostGIS format (GV_FORMAT_POSTGIS)
- Parameters
-
Map pointer to Map_info structure

◆ Vect_get_finfo_format_info()
| const char* Vect_get_finfo_format_info | ( | struct Map_info * | Map | ) |
Get format info as string (relevant only for non-native formats)
- Parameters
-
Map pointer to Map_info structure
- Returns
- string containing name of OGR format
- "PostgreSQL" for PostGIS format (GV_FORMAT_POSTGIS)
- NULL on error (or on missing OGR/PostgreSQL support)

◆ Vect_get_finfo_geometry_type()
| const char* Vect_get_finfo_geometry_type | ( | struct Map_info * | Map | ) |
Get geometry type as string (relevant only for non-native formats)
Note: All inner spaces are removed, function returns feature type in lowercase.
- Parameters
-
Map pointer to Map_info structure
- Returns
- allocated string containing geometry type info (point, linestring, polygon, ...)
