Fly Dane

Fly Dane is a regional partnership that allows local agencies to pool their resources for periodic updates of orthophotography, elevation, and planimetric data.

Case Study

Dane County participated in a federal GIS demonstration project (OrthoFinder) with the Wisconsin State Cartographer’s Office, University of Wisconsin-Madison, Wisconsin Dept. of Natural Resources, the City of Madison, and Ayres Associates. The project investigated issues related to the discovery, access, and use of digital orthophotography acquired by different agencies, at different times, over the same geography.

Imagery Review Process

The importance of robust quality assurance and quality control for orthophotography and related deliverables cannot be overstated. An important aspect of the Fly Dane project is the close working relationship between the contractor and the County on quality control. Because of the huge dollar investment, the project represents and because the work is accountable to so many partners, the County conducts a second level of review on the project deliverables.

As imagery comes in from the contractor, Dane County staff, using an ArcView application, reviews the imagery for large dust spots or scratches, ghosting, and warping. An ArcView Shapefile is generated noting the location and type of problem found. This process allows the contractor staff to quickly review the Shapefile and correct any problems with the imagery. Generally, imagery is reviewed, returned, corrected, and sent back to the County within five business days, causing no delay to the project schedule.

In 2000, the terrain data was also reviewed as part of the County’s in-house development of the countywide 4 ft contours. Data was checked and compared to other county field engineering records. Where problems were found, the contractor corrected the underlying terrain data.

The review process is beneficial to all parties, provided additional quality assurance and automated processes that assure fast, efficient, and consistent review. For Fly Dane 2005, the County will migrate the Ortho QA/QC Tool to the ArcGIS platform.
