DESCRIPTION

v.in.csv imports rows from a CSV (Comma Separated Value) file into a vector map as points with attributes. The separator for CSV is comma (,) by default, but it can be set to any single character such as semicolon (;), pipe (|), or tabulator.

NOTES

The module requires the "pyproj" Python package to work.

EXAMPLES

The following imports CSV file called latest_sites.csv in the current directory into the current mapset as point vector map named sampling_sites using the default coordinate transformation from WGS84. Latitude and longitude are in columns Site_Lat and Site_Long.

v.in.csv input=latest_sites.csv output=sampling_sites latitude=Site_Lat longitude=Site_Long
