Introduction

After a long time having announced this tutorial I have decided to build this IDRISI guide piece by piece now. Putting it together like modules makes it somewhat similar to the IDRISI package, which consists of approximately 120 single programs, called 'modules'.

IDRISI is a rasterbased GIS & image processing software serving a broad range of tasks. Its filestructure is rather simple and transparent such making it easy to cope with.

The tutorial will try to give you an overview to IDRISI's capabilities, and show you some ways how to solve spatial problems. It cannot replace the shipped manual(s) or the online helpsystem for the technical reference, and by no means this tutorial claims completeness!

It offers you two ways to discover: the pages are arranged in a somewhat linear sequence. You will find four direction-links at the top/bottom of each page. The left one guides you back to a previous page (not always strictly the last one) and the right lets you go on. Clicking the 'Index'-link points you to a page with the tutorial contents plus short descriptions of all issues, and finally the 'A-Z'-link puts you to a summary of all IDRISI modules, either alphabetically or thematically.

Each page shows the last-modified-date and a mail link for sending comments to the author.

This guide does not intend to teach you GIS-principles, so I presuppose a basic knowledge of GIS-terminology. Having access to an IDRISI license will be very helpful but not necessary. With a view to avoid heavy net-loads, I try to spare with graphics, and resize them to just legible. The ftp-downloadable tutorial version is likely to operate more prodigal (higher resolution graphics, animation sequences) - not released yet.
