The National Aeronautics and Space Administration (NASA) has funded the three-year Kentucky Landscape Census (KLC) project to develop a web portal providing access to GIS data and remote sensing derived change detection functionality for user groups in selected counties within the Commonwealth of Kentucky. This project is designed to improve access to data and GIS functionality in a web-based or web-enabled environment according to agreed upon, open standards for data exchange and integration. The larger KLC mapping portal is being implemented within the DotNetNuke portal framework, which includes username/password based site security and user profile management features. User access to tools, data, and other system features is provided at run-time based upon which security group(s) the user is a member of. GIS layers are brought into the portal from diverse sources, significantly at the county level and from the Kentucky Geonet (http://kygeonet.ky.gov). With respect to the change detection tools, two epochs in Kentucky were selected, for which statewide Landsat and change detection data exist: early 90’s and early 2000’s. Other imagery, such as IKONOS will be made available for display. The user interface will allow: viewing of imagery and image products, querying and reporting change statistics. This novel tool is a significant step toward bringing remote sensing tools and data to a plethora of potential users: Kentucky's citizens, private sector planners, modelers and local and state government decision makers in particular.
