History of VGI at the USGSNational Geospatial Program
USGS The National Map Corps The National Map Corps allows ordinary citizens to
contribute their location information to the map. Recently expanded to:
Continue expanding the project to more states. Add new features
Such as the Trails editor Keep up with current technologies
Keep the “Navigator” framework and Potlatch2 up to date
Seek solutions for migrating and merging Public Domain information back to OpenStreetMap.
Merging Volunteered Geographic Information Systems
Objective
Determine the technical and social issues involved with allowing information to be transferred from The National Map Corps project to the OpenStreetMap project.
Information added to The National Map Corps is only stored in The National Map Corps database. OpenStreetMap users do not have easy access to this
information in a familiar way. OpenStreetMap contains old information from USGS datasets,
but this information is no longer up to date.
Goals
There are many Volunteered Geographic Information Systems available.
We want users to be confident that adding information to our system will not require duplication of effort.
Users of OpenStreetMap will not have easy access to the information stored in Navigator without creating processes to merge and migrate information.
Technical Issues
The OpenStreetMap community offers several tools for manipulating their database. Osmosis: Java tool for programmable access to the OpenStreetMap
database. MapRoulette: A system to distribute data errors to a large group of
people for manual interpretation.
Errors to look for Omission Commission Some errors can be fixed programmatically, but others will need to
be put into a queue for a human to manually decide
Social Issues
OpenStreetMap currently has a large community following. This community is weary of data imports, and wants to
ensure that their standards for their areas are met. Determining the key people in each area is important to
ensuring that the data import will be successful.
