converting .SIT grass vector files

Kevin_Kingdon · February 10, 1995, 5:23am

Hi,
We are using a GPS system to make UTM co-ordinate measurements of a site.
The software which comes with the GPS system is able to output it's data
in what it calls a grass vector format. These files have a .SIT extension
on them. How can this format be imported into grass? (the software is now
2 or 3 years old). If this data could be imported directly into grass it
would be extremely helpful to our project.

I have also had problems setting up a new geographic region. I am using
xgrass and I tried the modify default region command from the pulldown
menu but was not able to save changes to the region that i created. I
also tried using the g.region command within the grass shell but was also
unsuccessful with this command. Any suggestions would be appreciated.

Thanks in advance,
Kevin

Got no idea how they look like. Try if they are ascii format. If yes try
to give an example. Probably you can load tham with v.in.ascii or
s.in.ascii. Try also just to convert an existing vector to ascii and try
to see how such a file looks like. It should be even straight forward to
create a header for it!

I have also had problems setting up a new geographic region. I am using
xgrass and I tried the modify default region command from the pulldown

also tried using the g.region command within the grass shell but was also

Just open with "vi" the file called DEFAULT_WIND (or something like that)
in you PERMANENT MAPSET. I remember I did it once like this!
