This sounds like a very interesting volunteer project. Just wish I had more time

The USGS is currently testing procedures for volunteers to collect and update USGS geographic data. Similar to how OpenStreetMap allows anyone to collect, edit, and use geographic data through an online map editor, the USGS has developed a prototype online editor customized to our data to allow volunteers to contribute data to The National Map and The National Structures Dataset .
We are looking for people like you to work with us to collect structures for the USGS. The data you will collect during this project will be loaded into The National Map . If you have access to the Internet and are willing to dedicate some time editing map data we hope you will consider participating!
For the past year volunteers have been updating data in Colorado with great results. As we get close to finishing Colorado we are opening up editing in 18 more states! Volunteers can now contribute data for Arkansas, Alaska, Colorado, Delaware
, Georgia, Idaho, Maryland
, Michigan, Montana, North Dakota, New Jersey, New Mexico, Ohio, Oregon, South Carolina, Utah, Washington, and West Virginia. You do not need to live in available states to participate. Our editing guidelines explain how you can contribute data from anywhere.
