Vegetation and Change Detection Imager
Introduction
Vegetation and Change Detection imager
The Vegetation and Change Detection imager, VCDi, is the first Taiwan-developed airborne multi-spectral imager. With the help of Agricultural and Forestry Aerial Survey Institute (AFASI), VCDi has successfully demonstrated the capabilities of taking images. These images can be applied to vegetation investigation, land change monitoring, precise agriculture and mudflow investigation.
