I was having a tough time finding a tool to map lat / long coordinates for a project. I needed to just copy and paste a bunch of coordinates and have points show up on a map, but I couldn't find a tool to do that, so I put a simple lat/long point mapping tool together.
Simply paste your geo-coded coordinates into the text box and hit submit. The page will reload and your points will be mapped. However, you must be sure to provide the latitude and longitude coordinates in the right format (this was just for internal use so I didn't bother with formatting or error checking). The right format is to use ONE combination lat,long per line. Separate the lat/long with a comma and there should be no spaces.
