First, I summarized of some earthquake data, for example lat, lon, depth and m agnitude. --------------------------------- lon lat depth Magnitude --------------------------------- 139.9, 37.7, 10, 3.1 141.0, 35.8, 10, 2.6 142.7, 40.8, 20, 4.4 ... --------------------------------- Second, this text data was imported to grass data by using v.in.ascii, as foll ows; cat data.txt | v.in.ascii fs=',' cat=0 x=1 y=2 out=quake columns='x double pre cision, y double precision, depth integer, mag double precision' So, I typed to 'v.vect quake' These points where the earthquake were displayed by cross (x) . Next, I tried to display new map as circle size of earthquake-magnitude. You probably want here: d.vect.thematic map=quake col=mag type=point themetype=graduated_points icon=basic/circle There are more options for coloring, etc. v.vect quake size=magnitude However, unsuccessful....What should I do?
