- Building on the foundation laid by the OSMCP, The VGI group will be
starting a new project to collect structures data in the City and County
of Denver. We will be soliciting volunteers from GIS Clubs in Denver for
this project and work with them to collect 28 different Community
Anchor Points. The data from this project will end up in The National
Map and therefore provide a real world learning opportunity for local
students to collaborate with the USGS.
The Structures VGI project will employ the same OSM Stack used for the
OSMCP and collect data to specifications necessary for use in The National
Map. This project will focus on a quality process to ensure the data is
certified to our standards. We will track costs and benefits by comparing
traditional collection methods to a VGI method. and provide meaningful
data to TNM that has been directly contributed by volunteers.
-
Goals
- Create a high impact project to display benefits of VGI/Crowdsourcing to the Leadership Team
- Provide udable strucutues data to TNM
- Work with Volunteers
- Document costs and rewards
- Create an alternative work flow that could potentially be operalizationized in the future
- Create project report that's publishable (OFR)
- Create project presentation and use it for outreach and education
- Once software and data are in place, the project timeline with be 3 months

Cost-Benefit Analysis
-
Staff

-
Tasks
-
Determine relevant costs associated with VGI Structures compared to USGS historic costs
- COSTS - will be primarily based on labor hours (edit, QC, training) and overhead costs (travel, hardware, training materials). Depending on the availibility of historic information, the following 3 "cases" could be quantified:
- Case 1 - USGS Collection AND QC (Base Case - USGS w/o partner); if available. Otherwise extrapolate estimates for Denver quads from existing data for other states.
- Case 2 - USGS Partner Collection AND USGS QC (Base Case - USGS w/partner); if available. Otherwise extrapolate estimates for Denver quads from existing data for other states.
- Case 3 - USGS Volunteer (student) Collection/QC AND USGS QC (VGI Case). Costs (labor hours) self reported by student volunteers and USGS. Potentially tracked in an excel spreadsheet.
- BENEFITS - are quantified as the difference between the "VGI Case" and the "Base Case" (USGS historic costs, with or without partner data, whatever are available).
- Net Costs/Net Benefits will be estimated by taking the total VGI Costs (labor and overhead) and subtracting the total "Base Case" (historic) costs.
- A positive value indicates a net benefit, or cost savings, to the USGS for implementing the VGI approach over the "Base Case" or historical USGS approach.
- A negative value indicates a net cost, or additional costs to the USGS for implementing the VGI approach compared to the Base Case" or historical USGS approach
- SCALE -
- Geographic Scale: 4 quads in Denver
- Temporal Scale: To Be Determined. Either a 1 time event (the 4 quads in denver) OR 5 year projection based on estimates derived for the 4 quads in Denver.
- Rationale for using a 5 year time frame is that it provides a longer period over which to absorb the overhead costs and provides a more realistic estimate of long-term benefits/costs to the USGS.
- DATA COLLECTION METHOD - Field (hand-held GPS) vs Office (review of aerial photography)? Need to be consistent in the methods used for each of the "cases", so analysis compares "apples to apples"
-
Create metric of data quality so that costs and benefits can be compared to a quantitative measure of the quality of the data produced.
- Exploring the feasibility of an "error frequency" statistic. For example, % of all records changed during QC (spatial changes, attribute changes or both), quantified using FME change detection tool. Results can be exported into excel and pasted into cost-benefit analysis quantification spreadsheet.
- Matthews suggested adding a field called "Status" attribute to the database that is populated for each structure during edit/QC. This would allow for the data to be queried by the FME tool, based on the stage in the workflow (collected, QC'd by volunteers, QC'd by USGS).
-
Create a meaningful baseline of data that can be added to by ongoing VGI projects
- This does not belong in cost/benefit analysis? (it is the end product of the exercise . . )

Outreach and Facilitation
-
Staff
- *Erin Korris
- Jennifer Walter
- Greg Matthews
-
Tasks
- Develop basic training materials
-
Process Documentation
- Track by census tract in an excel spreadsheet. Editors/QC'ers manually record own estimate of time (hrs). Hours information will be used in the cost-benefit analysis.
- Site Visits
- Progress Tracking
- Develop Certificate of Participation
-
Create certificate of participation
- Depending on types of volunteer opportunities created, this could be specific to each type
-
Develop internship/in-office volunteer opportunities
- Obstacle: Federal security clearance
- Internships could be developed with local universities
- Example: Experiential Learning Center at UC Denver; set up 1-3 credit hour unpaid internships
- In-office student volunteers
- Could receive certificate for completing a specified number of volunteer hours
- Independent Study credit
- Example: The UC Denver GIS certificate requires a 1 credit hour independent study
-
Develop progress tracking procedures
- Include which features have been completed, # of features completed, and hours
- Document should be filled out by volunteers
-
Contact local schools, clubs, and GIS organizations
- Research current GIS related organizations in Denver area
- Create presentation materials about project
- Site visits to inform groups about the project and to train volunteers
- Possibly create group events (point collection?) similar to OSM, with local GIS clubs and student groups
-
Develop Training Materials
- Build off of process documentation and the Guidelines for Contributing Structures Data to the National Map
- Include introductory material to OSM model and crowdsourcing
- Potential Training Needs:
- VGI Project and NSD presentation
