Description Usage Arguments Details Value Author(s) Examples

Generic function to import vector data of various formats into the GRASS environment.

1	import_vector_data(data, name, layer = NULL, proj_ref_obj = NULL, snap = -1)

`data`	character string or object; path to data vector file (shape), postgis data source name (dsn; see details), or sp or sf data object.
`name`	string giving the base name of the vector data within the GRASS environment (i.e. output)
`layer`	character string; default 1, particularly needed if data is a dsn for importing postgis data (see details)
`proj_ref_obj`	character; path to a georeferenced data file to be used as reference; only used if `data` is an sf of sp object, then, the two projections are compared to check if on-the-fly reprojection is needed for importing; typically the dem raster file used in this project.
`snap`	float; snapping threshold in map units. If != -1 (default) vertices are snapped to other vertices in this snapping distance during import. If used, the features are automatically cleaned afterwards (see GRASS tools v.import and v.clean )

For importing data from Postgis, all data base credentials must be supplied in data and the correct layer and, if the table containing the polygons are in a specific schema also that one (see example)

Nothing.
