done in FY10/11 USGS VGI Workshop in January 2010 OSMCP Phase 1
OSMCP Phase 2 Showing the results What we propose for FY12 2

OSM.gov OSM The National Map License change QC OSM.gov is a
separate instance of OSM software, populated with public domain
Official Govt Data data. OSM is the original OpenStreetMap. 5
6. OpenStreetMap Collaborative PrototypeOSMCP Phase 1 Goals:
Establish an OSM instance in a .gov environment. Organize input
through a well- defined set of features determined by TNM Best
Practices schema and standards. Determine if a non-USGS entity can
successfully edit features through the OSM interface. 6

18. Preliminary Findings of Internal Review General
Observations The data were greatly improved with the addition of
many new points, the identification of obsolete points to be
removed, and the update and addition of correct attribute
information. Observation 1 Directions were followed very well.
Observation 2 Many issues with the data were related to
non-critical attributes. 18
19. LEVEL OF EFFORT COMPARISON 19
20. Recommended Next Steps Improve cost/benefit with an
expanded project which takes advantage of the crowd in
crowd-sourcing . Include an adopt-a-quad approach for data
evaluation. Per FY12 Guidance: Move OSMCP platform to a cloud
computing environment. Work with partners on outreach for the
projects recommended. Strengthen web information/create public
interface. Work on Structures and Trails in the State of Colorado.
Include an Americas Great Outdoors theme for Trails collection in
cooperation with NPS; possibly include an adopt-a-quad approach.

21. Phase 3 Structures Collaboration and Volunteers Not
currently in FY 12 budget. Requesting project support at the same
levels as FY11 ($205,545). Reduce unit cost. State of Colorado.
Data - Seed from GAZ + volunteers + possibly State data facilitated
through the State Liaison Program Carol Giffin. 17 priority
Structures. Improve usability of software interface. Improve
automated processing of data validation and checks. Demonstrate an
Adopt A Quad system for quality control. Demonstrate a Rewards
System. Ease of use make collection process possible for Fifth
Graders to contribute. 21
22. Trails VGI Investigation FY 12 Transportation Initiative
Current Planned FY 12 Budget: $86,646 Demonstrate authoritative
dataset of federal trails over AOI Collaborate with other federal
agency (NPS) AOI in portion of Colorado (possibly one or more
national parks) Target outdoor groups as volunteer pool Web
interface for editing trails and uploading GPS tracks QC by
individual land management jurisdictions Coordinate with other
NGTOC FY12 projects to evaluate federal trails data Supports the
Presidents Americas Great Outdoors initiative to connect Americans
to the outdoors. 22
