GRASS 6 Tutorial

From GRASS-Wiki
Jump to navigation Jump to search

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, especially in the vector engine and attribute management. For further reading, see the references below.

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!

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.

NOTE: This tutorial here still awaits the merge 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.
