I'm working on a new open-source project to make it easy for anyone to show their data in an interactive map on the web, and I need volunteers to test it. I'm looking for people who have spreadsheets they'd like to turn into maps, and part of what I'm looking to test is that I'm covering the most popular ways of specifying locations, so I'm interested in everything from zip codes, to street addresses, latitude and longitude to country names. If this sounds like you, please drop me an email via [email protected] and I'll get you started making maps right away.
