Mercatalog helps you geotag your pictures and find them on a map.

Find photos right where you took them. Mercatalog hides sophisticated geotagging algorithms behind a completely visual interface, helping you easily match your photos up with your GPS tracklogs. When you're done geotagging (it doesn't take long!), export as a KMZ file for viewing in Google Earth, or drag out copies containing EXIF location metadata.
