Dear All
I thank for some useful advices.
So, I tried to use the 'v.distance' command.
Coordinate system of shoreline (300 lines) and the investigation spot (259
points) is wgs84.
# calc distance
v.distance from=investigation_points to=shoreline upload=dist column=distance
# view table
v.report map=investigation_points option=length
cat|distance|length
1|0.008047|0
2|0.007871|0
....
258|0.001226|0
259|0.001249|0
Column of distance includes decimal point...I don't understand why is it that
value of the distance becomes the decimal point.
I want to genereate distances in a kilometer and a meter.
Give me some more advice...
