Geographic access analysis is a method used to assess the proximity of various resources, services, or facilities in relation to specific geographic locations. It is an essential report needed by business, the medical industry, government, and other fields. One common use is to understand which stores or offices are closest to a list of customers.

This application allows you to upload a set of location postal codes along with a list of target postal codes in an excel or csv file. Two formats of input are allowed. The first format is two columns of postal codes with the first column being locations and the second column being targets. An example of this file can be downloaded here. Labels can also be associated with the locations and targets as shown in this example file.

The user can set a radius distance along with the maximum number of targets to be returned before starting. Only targets within the radius specified up to the maximum number will be shown. Both US Zip Codes and Canadian Postal Codes are supported. The tool can analyze up to 300 locations and 2,000 targets.

After the input file is uploaded a preview of the output report will be shown. This shows the closest locations by distance in ascending order for the first few targets in the file. A count will be shown with each target showing the number of locations within the radius.

Once the preview screen is approved an option to purchase the complete report will be presented. The cost of the report is $0.02 or 2 CDXStreamer requests per target with a minimum charge of $9.95. An example output report can be reviewed here.
