[GRASSLIST:5636] Importing Data.

GRASS GRASS user
1

I am new to GIS and I like to borrow a data set from a person who uses
_ARC_GIS_8.3.

I have installed GRASS 5.7 on Linux. Data in which format I should seek
from ARC user, so that I can easily use it in GRASS 5.7.

  1. Save the ARC-INFO files as SHAPE files
  2. Open a NEW location in the 1st menu, just take XY coordinate system, accept what ever prompts are give, for region.
  3. U will find this file as a vector added to Ur dataset.
    IMPORT it with ‘-o’ in the command.
  4. Go to the GIS menu and set this vector as a region.

There U have a nice GRASS5.7 vector from ARC-INFO.

1. Save the ARC-INFO files as SHAPE files

(ie for vector data; for raster data you can load an Arc binary grid
into GRASS with r.in.gdal)

2. Open a NEW location in the 1st menu, just take XY coordinate
system, accept what ever prompts are give, for region.

3. U will find this file as a vector added to Ur dataset. IMPORT it
with '-o' in the command.

(with v.in.ogr)

I think it might be better to either create a new location of the
correct projection (if known) or use v.in.ogr or r.in.gdal with the
location= option to create a new location with the correct projection
parameters automatically (make sure shape files generate .prj!) rather
than leavcing it unset and overriding the projection check with -o.

You only have to do this once, best to get it correct at the beginning I
think.

4. Go to the GIS menu and set this vector as a region.

g.region vect=your_map

etc

Thank you Ravi and Hamish for your help.

Sub : Single user mode booting under grub LOST #266

To enter single user mode under grub, press "e" [edit] at the
grub boot menu and edit the boot parameters "kernel /vmlinuz
root=/dev/hdN single" (where N = your root partition)... Then
reboot using "b" [boot]... Easy ?
