    Abstract: This paper provides a systematic description to the accuracy of airborne laser-ranging multispectral-imaging mapping system (ALRIMS). This integrated system driven by the availability of global positioning system (GPS), compact ruggedized solid state lasers, high-precision airborne inertial navigation systems and rugged precise high speed multispectral scanner is developed for capturing topographic and multispectral information of the earth surface in the form of georeferenced multispectral image with digital elevation model (DEM). The DEM and georeferenced multispectral imagery has matched accurately when they are captured. This is essential for many remote sensing purposes, such as geometric and radiometric rectification of the multispectral image, the utilization of auxiliary information for multispectral image classification, etc. This is reached by using laser-ranging multispectral-imaging coupled scanner (LRMICS) developed by our team in IRSA.
