GPS-based video mapping for natural resource management

摘要

The new technologies involving Global Positioning Systems (GPS) and Geographic Information Systems (GIS) have revolutionized the data collection, storage, manipulation and display of features useful for natural resource management. Recently georeferenced images have allowed visual information to accompany the digital geographic information embedded in the GIS. This project involves the data collection procedure of georeferenced video for natural resource management. Satellite-based differential GPS information is collected on the audio track of a digital camcorder using the Red Hen VMS Professional. Georeferenced still images and video clips are captured and incorporated into the GIS to develop a database of natural resource management and recreation features. Applications involving Colorado State Parks, Rocky Mountain National Park, off-road vehicle tracking and underwater video mapping have been explored. Captured features are determined for each application, but for trail mapping include erosion control structures, campsite, signs, bridges, water sources and scenic views.
