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 calledlatest_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
SEE ALSO
- v.in.ascii for the underlying module with finer control (but not coordinate transformation),
- v.in.ogr for an alternative CSV import using GDAL/OGR.
