GRASS 6 Tutorial/de

Das Freie Software/Open Source GIS GRASS 6 ist voll funktionsfähig und stabil für den produktiven Einsatz. Dieses Tutorial bietet Ihnen Hilfe an, um sich mit der verbesserten Funktionalität, vor allem in der Vektorverarbeitung und Attribut-Management vertraut zu machen. Für weitere Informationen, siehe die Hinweise unten.

Haftungsausschluss: Sollten die hier beschriebenen Beispiele nicht richtig funktionieren, Sie sind herzlich eingeladen, uns weitere Beispiele und/oder Code Bugfixes/Erweiterungen mitzuteilen bzw. hier einzutragen. Viel Spass mit diesem Wiki!

Dieses Tutorial richtet sich an GRASS Anwender, die von einer früheren Version auf die aktuelle Version von GRASS migrieren wollen. Wenn Sie Anfänger sind, beachten Sie bitte auch die weiteren Bücher und Tutorials.

NOTE: This tutorial here still awaits the merge of the previous GRASS 5.7 tutorial.

Introduction

New GRASS development has 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). This system provides the power of true relational databases 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.

Getting started in general
