One of my client’s requirements was to create and open source geospatial DBMS to hold utilities and city shape files. As looking through the internet, I found PostGIS is an open source software program that adds support for geographic objects to the PostgreSQL object-relational database. As project reference, I choose PostGIS in Action, as project accomplished successfully I realized my judgment was excellent.
PostGIS in Action is a very comprehensive introduction to PostGIS for developers of all levels of experience. Basically it is split into 3 parts:
Part 1- Nice and slow startup with PostGIS. You can skip this section if you have prior knowledge about any kinds of spatial databases and geometry data types.
Part 2- Put PostGIS in work. It contains technical details on proximity analysis, geocoding addresses, manipulating polygons and lines, and scaling and rotating geometries as well as efficient queries and how to tune your database and
selection of appropriate indexes and keys for your data.
Part 3- Use of PostGIS with other tools and frameworks. It describes manage raster datasets in PostGIS with PostGIS raster module, development of Web applications using PostGIS.
The Book will provide the much needed skills in building a spatial database, Application Server, Desktop GIS and Cartographic map renderer, Map tile server and Web map component using the following software: PostGIS/PostgreSQL, GeoServer, Apache/Tomcat, uDIG, Openjump, QGIS, GRASS GIS and Openlayers.
