Creating a Working Directory
The system enables you to access files anywhere but it is a good strategy to carefully
organize your data (project information and files) before carrying out any processing.
To start this tutorial, please create a working directory called
D:\Tutorial
. A general rule
to follow in working with Geosoft applications is to avoid working in the directory where
Oasis montaj
was installed. In this tutorial, we will follow this rule by keeping all the
working data files in
D:\Tutorial.
Before you Begin
This tutorial uses sample data (
casaber.gdb
,
casaber.grd
,
casaber.grd.gi
,
Oasis
montaj.map
,
oasismontaj.map.gm
, and
xyz_format.xyz
) which is available on the
Geosoft website
http://www.geosoft.com/pinfo/oasismontaj/free/montajviewer.asp
.
Before you begin the tutorial, download and copy the data files to your working directory
D:\Tutorial.
