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, xyz_format.xyz, and Oasis
montaj v61.map) which is available on the Geosoft website
http://www.geosoft.com/free/downloadfree.html. Before you begin the tutorial, download
and copy the data files to your working directory D:\Tutorial.
Creating a Project
To work in Oasis montaj requires an open Project. An Oasis montaj "Project"
encompasses every item in your working project; from the data files in your project
(databases, maps, and grids), to the tools used (including 3D tool and the Project
Explorer), to the project setup including the menus you have displayed and whether you
are working on a map or profile and the state in which you left it the last time you used it.
The project also controls your working directory. Projects are saved as (*.gpf) files. If you
open an existing project from a directory, the system assumes that all your project files are
located in the same directory. To streamline your work, as well as keep it organized, you
may wish to make sure that your project file is in the same directory as the other files you
want to use. We recommend that each project you work on have its own project (*.gpf)
file.
The Project Explorer tool enables you to browse as well as open any project item. The
Project Explorer has two windows, the Data window that includes all data files included
in the project and the Tools window that organizes and maintains the project tools. To
