Introducing Geographic Information Systems with ArcGIS: A Workbook Approach to Learning GIS, 3rd Edition

Address Geocoding

STEP-BY-STEP

Exercise 9-3 (Project)

Experimenting with Addresses and Coordinates

____ 1. Using the operating system of your computer, use Notepad to open the text file

[___] IGIS-Arc\Address_Geocoding

\Clinton_County_OH_Type1_1994_TIGER_Records.txt

Clinton_County_OH_Type1_1994_TIGER_Records.txt is a raw TIGER file. Notice it is composed of only letters and digits—228 of them in each record. I show you this so you can understand that the basic TIGER files are simply character files. They contain geographic information, but to plot this information, you must convert the files into GIS files (e.g., geodatabase feature classes, shapefiles).

____ 2. Locate the sixth record from the top of the file. Verify that it describes the 4000 block of state highway 729. Verify that the longitude of the FROM node of that block is 83.613958 WEST. What is the latitude of the TO node of that block? ________________.

____ 3. Looking at that same record you can discover that the zip code on the left of the highway is the same as the zip code on the right. In what zip code does this block of highway lie? ________.

____ 4. Start ArcCatalog. Copy the folder

[___] IGIS-Arc\Address_Geocoding

into

Make a folder connection to the new folder.

____ 5. Start ArcMap. Add as data
