History of VGI at the USGSNational Geospatial Program 4. USGS The National Map Corps The National Map Corps allows ordinary citizensto contribute their location information to the map. Recently expanded to: AR, AK, CO, DE, GA, ID, MD, MI, MT, ND, NJ, NM, OH, OR, PA, SC, UT, WA, & WV Further expansion coming June 18 AL, AZ, CA, CT, FL, IL, LA, MA, MS, NE, NV, NH, RI, SD, VT & WY Similar to OpenStreetMap, built on the sameplatform. Only allows users to modify point data types. http://navigator.er.usgs.gov 5. Current Extent of The National Map Corps Project 6. What kinds of points are being added tothe map? Education School College / University Emergency Response and Law Enforcement Fire Station / EMS Station Law Enforcement Hospital Ambulance Service Correctional Facility Government & Military State Capitol Mail & Shipping Post Office Public Attractions & Landmark Buildings Cemetery 7. OpenStreetMap Technologies The OpenStreetMap website uses Ruby on Railsfor its user management platform. The backend database is PostgreSQL. The database is not PostGIS The database uses key : value relations which areindexed by a version number. The default mapping system is called Potlatch2 Written in ActionScript 8. Backend Services Running on a Linux server: Production: http://navigator.er.usgs.gov Staging Development: Local Machines Consists of four projects: Navigator The website itself, user management Potlatch editors The editing interfaces Tiles A custom tile caching service that makes editing easierfor users. Webhelp The help system for the systems users. 9. Potlatch Editors There are four Potlatch Editors Standard Adopt-A-Quad (AAQ) Quality Assurance (QA) Trails It is based off of the OpenStreetMap projectsPotlatch2 editor. Written in ActionScript 3 using the open-source Flexframework Uses OAuth for user identification 10. Editing Interface 11.

Add new features Such as the Trails editor Keep up with current technologies Keep the Navigator framework and Potlatch2 up todate Seek solutions for migrating and merging PublicDomain information back to OpenStreetMap. 17. Merging Volunteered GeographicInformation Systems 18. Objective Determine the technical and social issues involvedwith allowing information to be transferred fromThe National Map Corps project to theOpenStreetMap project. Information added to The National Map Corps is onlystored in The National Map Corps database. OpenStreetMap users do not have easy access to thisinformation in a familiar way. OpenStreetMap contains old information from USGS datasets,but this information is no longer up to date. 19. Goals There are many Volunteered GeographicInformation Systems available. We want users to be confident that adding informationto our system will not require duplication of effort. Users of OpenStreetMap will not have easy access tothe information stored in Navigator without creatingprocesses to merge and migrate information. 20. Technical Issues The OpenStreetMap community offers several tools formanipulating their database. Osmosis: Java tool for programmable access to the OpenStreetMapdatabase. MapRoulette: A system to distribute data errors to a large group ofpeople for manual interpretation. Errors to look for Omission Commission Some errors can be fixed programmatically, but others will need tobe put into a queue for a human to manually decide 21. Social Issues OpenStreetMap currently has a large communityfollowing. This community is weary of data imports, and wants toensure that their standards for their areas are met. Determining the key people in each area is important toensuring that the data import will be successful. 22.
