The new edition of Open Source GIS: A GRASS GIS Approach is now available! With this third edition, we enter the new era of GRASS 6, the first release that includes substantial new code developed by the International GRASS Development Team. The dramatic growth in open source software libraries has made GRASS 6 development more efficient, and has enhanced GRASS interoperability with a wide range of open source and proprietary geospatial tools. The book is based on GRASS 6.3.

Thoroughly updated with material related to GRASS6, the third edition includes new sections on attribute database management and SQL support, vector networks analysis, lidar data processing and new graphical user interfaces. All chapters are updated with numerous practical examples using the first release of a comprehensive, state-of-the-art geospatial data set.
