The landscape changes continually as a result of human and natural forces. Change detection can be accomplished using satellite imagery or aerial photography, advanced image processing techniques, and GIS analysis to map the spatial location and magnitude of land cover change.
Sanborn has pioneered the development of remotely sensed change detection methods to provide the necessary information for good decision-making. We have conducted hundreds of projects that utilize image classification and multispectral satellite imagery to analyze land cover and its changes over time. The members of our team have successfully completed change detection projects covering millions of acres throughout the world, and continue to apply these methods to address our client’s forestry, fire and ecosystem management, urban planning, and emergency response requirements.
Change detection techniques applied in the natural resource management arena are used to identify changes in vegetation cover over time through natural or man-made events. The main deliverables include:
- GIS layers of change data for a given time period
- Cause database that explains the nature of the changes
