Hello,
I have a series of coordinates
(latitudes and longitudes) each one/several associated to a code
(from 1 to 28). I used function points (latitude, longitudes) to
transfer them to a per-prepared map.
1- I wonder how I might be able to
automatically add codes (1-28) to the map too?
2-Moreover, mostly there are a few
codes from the identical coordinates. What is the function to avoid
overlapping of codes on the map?
3- I want to draw closed line around
some geographical areas to define the habitats.
Your help in any way (introducing
manuals, codes, etc) is appreciated.
All the best,
Mehdi
