Everyone loves power tools. The GDAL and OGR utilities are the power tools of the GIS world, and best of all, they're free.

The Geospatial Data Abstraction Library (GDAL), including its subproject OGR, is the preeminent open source data access library that provides GIS commands and tools. It is used behind most of the open source geospatial applications and also sits behind many of the leading proprietary GIS applications on the market today. Along with the programming libraries come several powerful command line utilities, intended to be run by being typed into a terminal or command prompt window.

The utilities include tools for examining, converting, transforming, building and analysing data. This book is a collection of the GDAL and OGR documentation, but also includes substantial new content designed to help guide you in using the utilities to solve your current data problems.

Inside you'll find a quick reference for looking up the ... Lire la suite

What is pgRouting? It's a PostgreSQL extension for developing network routing applications and doing graph analysis.

Interested in pgRouting? If so, chances are you already use PostGIS, the spatial extender for the PostgreSQL database management system. So when you've got PostGIS, why do you need pgRouting? PostGIS is a great tool for molding geometries and doing proximity analysis, however it falls short when your proximity analysis involves constrained paths such as driving along a road or biking along defined paths.

PostGIS alone can't help you apply costs and resource constraints to your travels, such as traffic congestion, mileage restrictions, or allocating resources like vehicles. pgRouting is a complement to PostGIS that allows you to incorporate costs and path restrictions to your proximity analysis.

pgRouting is well suited to building travel navigation systems and computing driving distance polygons for places of interest. While ... Lire la suite
