Performance Evaluation of Optech's ALTM 3100: Study on Geo-referencing Accuracy

R.V. Ussyshkin, B. Smith, and A. Fidera

Abstract: Airborne laser scanning is used to generate topographic maps with accuracies on the decimeter level. Recent studies of the Optech ALTM 3100 Airborne Laser Terrain Mapper system demonstrate that this instrument is capable of relative accuracies on the sub-decimeter level. The limiting factors in obtaining absolute sub-decimeter accuracies are the GPS and INS systems that are required to provide absolute position and orientation during flight. This paper presents a summary of the vertical accuracy assessment results for the ALTM 3100, a discussion of the contributions to overall error in this instrument, and presents a new study on the geo-positioning system accuracy to be performed in the coming months.
