Chapter 8 Getting There Quicker with Geospatial Technology
Chapter Wrapup
Networks, geocoding, and routing are all powerful tools for use in geospatial
technology. With GIS, these concepts are used in a variety of applications and
businesses today. Today 911 operators can geocode the address of a call and
emergency services can determine the shortest route to a destination. Delivery services can use geocoding and routing applications to quickly determine
locations and reduce travel time to shortest paths. Also, the use and development of these types of techniques in vehicle navigation systems represents a
rapidly changing technology that keeps getting better.
Geospatial Lab Applications 8.1 and 8.2 will use online geocoding applications, as well as Google Earth and GIS software for investigating shortest
paths and TIGER/Line mapping uses. In the next chapter, we’re going to start
looking at a whole different aspect of geospatial technology—remote sensing. All of these overhead images that you can see on applications like Google
Maps or MapQuest have to come from somewhere to get incorporated into the
program, and we’ll start looking at the methods behind remote sensing in the
next chapter.
