We are continuing to add to our product line of CDXStreamer browser-based tools. A new application for Geographic Access Analysis has just been released.
Geographic Access Analysis (also known as closest store 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.
This tool allows you to upload a set of location postal codes along with a list of target postal codes in a spreadsheet in an excel or .csv file. The user can set a radius distance along with the maximum number of targets to be returned before starting. A report will then be produced which orders the locations by distance in ascending order for each target. Only targets within the radius specified up to the maximum number will be shown. Both US Zip Codes and Canadian Postal Codes are supported.
For a tutorial on using the new app please see the following video.
If you would like to see how this all works you can try CDXStreamer for free for 7 days for up to 1000 total requests by signing up for our free trial.

Recently we have received reports that users were experiencing problems accessing Bing Maps when using the CDXRouteBing and CDXLocateBing functions. Microsoft has made a security change involving https: secure connections being made to the Bing Maps servers. CDXZipStream uses https: to protect the location data being sent to Bing against unauthorized third parties. The security standard TLS 1.2 is now required for any transactions with the Bing Maps server. Any older standards such as TLS 1.1 are now rejected.
If your system is not configured to use the new standard by default you will see errors messages such as "Location Not Found or Bing Maps Did Not Respond" returned consistently for all formulas. You can also try entering a known good location or route such as "=CDXLocateBing(0,"90210").
If you are experience this problem on your system please download and and install our most recent installation file available at the following link.
