Paper Abstract
Very accurate geo-location (geo-coding) of imagery taken at long range is a very large challenge.
Whereas GPS can supply a very accurate sensor position, the hardware for the required precision pointing
can have a very large cost. Roth, et al (2005) showed that because of the accuracy of lidar range-data, a
tri-lateration method (called Multi-Look Lidar or Multi-Look Geo-Coding) can achieve very accurate geocoding
at very long ranges and very low cost by using data-driven processing. This paper presents
extensive flight-testing results using commercial airborne lidar. Because the tri-lateration method produces
a large number of control points, the resulting accuracy of the geo-coded lidar data is somewhat better than
that predicted for a single control point due to control-point averaging.
