Area of Interest


Is there a certain area you are interested in editing? Maybe the town you grew up in, or the city where you currently live?

Pick an area and look for authoritative lists of features in that area. For example, if you are editing in a specific county, look for a list from an authoritative source of all of the fire departments or police stations in that county.

2. Use the same process described in the personal knowledge example to determine if a point already exists for the feature. If a point does not exist, add a point in the correct location and fill out the name as well as the address, city, state, and zip code if available.
