With the help of the internet & accompanying tools, creating & publishing online maps has become easier & rich with options. Many web sites now have map components, & interactive maps are particularly useful in allowing the user to select particular layers or elements of interest in the information presented. Developers who want to publish maps on the web often discover that commercial tools cost too much & hunting down the free tools scattered across Internet can use up too much of your time & resources. This isn`t a book about web design skills, & it doesn`t teach cartographic theory
- although it does introduce you to the important but sometimes intimidating subject of map projections & coordinate systems. Rather, it shows you how to create maps, even interactive maps, with open source tools, including Map Server, Open EV, GDAL/OGR, & Post GIS. It also explains how to gather free map data, & how to underst&, store, use, & share it both over the traditional Web & using OGC-standard services like WFS & WMS.
