This chapter’s lab will introduce you to the concepts of calculating a shortest
path between stops along a network as well as generating directions for the path
using Google Earth and Google Maps. You’ll also be performing geocoding using a Web service, examining the geocoding results, then performing some basic
spatial analysis of the results and a TIGER file using Google Earth and ArcGIS.
The previous version of this lab (8.1 Geospatial Lab Application: Geocoding and Shortest Path Analysis: AEJEE Version) uses the free ArcExplorer Java
Edition for Educators (AEJEE). However, this lab provides the same activities
for use with ArcGIS 10.
Objectives
The goals for you to take away from this lab are:
a Familiarizing yourself with the shortest path and directions functions of
Google Earth.
a Using Google Maps to alter the shortest path to account for route changes.
a Utilizing an online geocoding service to geocode a series of addresses,
then examining the results.
a Using ArcGIS to plot the results of a geocoding operation.
a Examining some basic spatial analysis of locations and their relation to a
road network (TIGER file) in ArcGIS.
Obtaining Software
a The current version of Google Earth (6.0) is available for free download
at http://earth.google.com.
a The current version of ArcGIS (10) is not freely available for use. However,
instructors affiliated with schools that have a campus-wide software license
may request a 1-year student version of the software online at http://
www.esri.com/industries/apps/education/offers/promo/index.cfm.
Important note: Software and online resources sometimes change fast.
This lab was designed with the most recently available version of the software
at the time of writing. However, if the software or Websites have significantly
changed between then and now, an updated version of this lab (using the newest versions) is available online at: http://www.whfreeman.com/shellito1e.
