Preface

In the past, professional spatial analysis in the business sector was equivalent to buying an ArcGIS license, storing the data in some kind of Esri database, and publishing results with the ArcGIS Server. These trends seem to be changing in the favor of open source software. As FOSS (free and open source software) products are gaining more and more power due to the hard work of the enthusiastic open source GIS community, they pique the curiosity of the business sector at a growing rate. With the increasing number of FOSS GIS experts and consulting companies, both training and documentation--the two determining factors that open source GIS products traditionally lacked--are becoming more available.
