One of our new favorite tools is batchgeo which allows you to take geographic information you have in a spreadsheet or from a table on a webpage and turn it into an interactive map. Not only can you map out your locations, you can also color code them to group like items on the map. Once you've got your map set up the way you like, batchgeo will give the map its own link to share with whomever you like. They also provide the HTML code in case you want to embed it to a webpage. It's a wonderful time saver and all at the low, low price of free. They have a professional service available as well if you need more features, but I was able to produce some pretty handy maps using their free version. Check out the video below for a quick tutorial on batchgeo.
