BatchGeo
BatchGeo is a web-based tool that allows users to quickly and easily create maps from location data. With BatchGeo, users can take a list of addresses or coordinates and turn them into a customized map that can be shared with others. The service is often used for business purposes, such as creating a map of customer locations or sales territories, but it can also be used for personal purposes, such as mapping out a road trip or vacation itinerary.
To use BatchGeo, users simply upload a spreadsheet of location data or copy and paste it into the tool. BatchGeo then geocodes the data, meaning it translates the addresses into latitude and longitude coordinates that can be plotted on a map. Users can customize the map by adding labels, markers, and other features, and can then share the map via a link or embed code. BatchGeo also offers features such as the ability to search for locations and calculate distances between points on the map.

CDXGeoData
While our other software programs require a Windows-based version of Microsoft Excel, CDXGeoData provides access to location analytics from Windows, Linux, MAC OS and other platforms. Functions available include address correction, zip code lookup by address, geocoding, routing, radius analysis and many others. Use our free Excel add-in and pre-developed spreadsheet apps or roll your own application. CDXGeoData functions can also be accessed through a powerful Excel add-in that works in both Windows and MAC OS environments. No additional software needs to be installed - you just need an internet connection. Custom templates can also be developed in Excel and other platforms without worrying about licensing for additional users. You just manage the requests made to the service, not the number of users.
