Skill Drill: Geocoding an Address and Creating a CSV Table to Import As XY Data

In this scenario, you will predict the overland movement of the wolpertinger during the fall migration from their den locations to the town of Orick. As a point of reference, the U.S. Post Office will serve as a point location representing the relative center of town.

US Post Office

121147 US-101, Orick, CA 95555

Use Google Maps or another online service to geocode the address of the U.S. Post Office in Orick and obtain the latitude and longitude values in decimal degrees. Many websites will geocode a single address for free. Be sure to find out which spatial reference system the website uses to generate the decimal degree values. The most common spatial reference on the web is WGS 1984. In Microsoft Excel, create a CSV table with the following field headers: name, latitude, longitude. You may use the name provided in the table above as the name attribute for the town of Orick. Enter the latitude and longitude values in the appropriate fields. Save as a CSV table and close Excel.

NameLatitudeLongitude
Orick 41.xxxx -124.xxxxx

In ArcMap, add the CSV table as XY data using the same workflow as for the den locations. Use the Project tool if necessary. In the end, you should have a shapefile representing the town of Orick using the NAD 83 UTM Zone 10 spatial reference system.
