In this part . . .

The most advanced functions of GIS lie in the systems’ capacity to measure geographic features, including distances, areas, networks, surfaces, and all their related characteristics. In this part, you find out how GIS performs individual tasks, such as finding shortest or fastest routes, analyzing visibility, assessing fluid accumulation and flood zones, and many others. Also, you discover how to combine these individual operations to create complex, real-world models, which are (in my opinion) the most rewarding pinnacle of the GIS analyst’s art and science.
