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