Abstract
In the previous chapters, you have learnt about remote-sensing technology which is one of the reliable sources of the spatial database. In this chapter, you will learn about the Global Positioning System (GPS). As the name denotes, it provides an exact position on the Earth. This is one of the most reliable sources for providing positional information for the GIS environment. After reading this chapter you should be able to understand the following:
-
The background to the US, Russian and Indian Global Positioning Systems
