Monitoring Trail Use with Imagery at Joshua Tree National Park
Track: Parks and Natural Reserves
Author(s): Jennifer Lee
This project implemented a geospatial tool that allows park staff at Joshua Tree National Park to monitor and assess current and future impacts of recreational use along both official and social trail networks. The toolset allows a single user to assess disturbance impacts through the analysis of imagery and vector data. Image processing included rectification, mosaicing, as well as multi-spectral analysis to assess vegetation disturbance. A raster to vector process was also used to capture all designated and social trails within the scene. Analysis was performed using a series of image dates to integrate a temporal context to the product for a predictive component. All work was performed using ArcGIS 9.3 and the resulting tool extensions were created using ModelBuilder and VBA scripting. This toolset will allow for a more standardized method of monitoring and managing the landscape while minimizing cost.
