GRASS GIS version 6.4 is fully operational and stable version that can be used for production use. This tutorial will familiarize you with the improved functionality and will focus on raster and vector data management as well some basic spatial data analysis.

This tutorial is intended for GRASS GIS users who want to migrate from a previous release to the new GRASS Version. If you are a beginner, please also consider additional books or tutorials as well as consulting the Introductory Material.


Disclaimer: In case the examples described here do not work properly, you are kindly invited to send us further examples and/or code bugfixes/enhancements. Enjoy the WIKI!

NOTE: This tutorial is under construction and is incorporating sections of the previous GRASS 5.7 tutorial.

Introduction

New developments in GRASS GIS have made major improvements to the vector architecture. The most significant change includes a new 2- and 3-dimensional vector library that manages vector attributes in standard database management systems (DBMS), providing a fully relational database for vector attribute management, while preserving the flexibility of traditional GRASS topological tools. GRASS now also incorporates true 3-dimensional voxels in the NVIZ visualization environment as well as numerous enhancements to virtually every tool in the GRASS library.

If you are new to GRASS GIS and plan to use the command line inteface and/or Linux, it is recommended that you read the Introductory Material for Linux.

Getting started - how to migrate to the new GRASS version

If you have already installed GRASS GIS on your system, you can continue to the next section. Otherwise, please consult the [Installation Guide], which covers all of the main operating systems. If you want to compile GRASS GIS from source, you should follow these [Instructions].


To launch GRASS GIS, simply type 'grass64' on the command line.

Raster data management

Tutorials and books written for GRASS 4 and 5 should for the most part still work.

Vector data management
