The multispectral data from the Landsat 5 (L5) Thematic Mapper (TM) sensor provide the backbone for this extensive archive. Historically, the radiometric calibration procedure for the L5 TM imagery used the detectors' response to the internal calibrator (IC) on a scene-by-scene basis to determine the gain and offset for each detector. The IC system degraded with time, causing radiometric calibration errors up to 20%. In May 2003, the L5 TM data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center through the National Landsat Archive Production System (NLAPS) were updated to use a lifetime lookup-table (LUT) gain model to radiometrically calibrate TM data instead of using scene-specific IC gains. Further modification of the gain model was performed in 2007. The L5 TM data processed using IC prior to the calibration update do not benefit from the recent calibration revisions. A procedure has been developed to give users the ability to recalibrate their existing level-1 products. The best recalibration results are obtained if the work-order report that was included in the original standard data product delivery is available. However, if users do not have the original work-order report, the IC trends can be used for recalibration. The IC trends were generated using the radiometric gain trends recorded in the NLAPS database. This paper provides the details of the recalibration procedure for the following: 1) data processed using IC where users have the work-order file; 2) data processed using IC where users do not have the work-order file; 3) data processed using prelaunch calibration parameters; and 4) data processed using the previous version of the LUT (e.g., LUT03) that was released before April 2, 2007.

The potential of low-end imus for mobile mapping systems / A. Barsi in Revue Française de Photogrammétrie et de Télédétection, n° 185 (Mars 2007)

The road networks often cannot cope with the increased traffic load; moreover, the roads in bad condition reduce the overall capacity of a network. Pavement condition is a central aspect of road transportation infrastructure management, and is particularly highlighted in Hungary; the loss in travel time, the damage in vehicles results in significant indignation in society and gives an everyday topic for the actual political life. Scheduling road construction works requires effective monitoring of road conditions and the various components of a particular network have to be classified by quality. This paper introduces a complex road pavement measurement system designed primarily for pothole and crack detection. The system, installed in a vehicle is composed of a navigation unit, image acquisition module and a photogrammetric image-processing subsystem. The navigation unit consists of an integrated GPS/INS system; the trajectory and attitude of the vehicle at the required accuracy is provided by a Kalman filter. All the sensors and a high-speed computer are mounted on a pick-up. The low-end inertial measurement units (IMUs) have continued to improve in the last years, which broadened their application fields. The paper discusses the experimental results of the IMUs. First we compared the performance of two low-end IMUs on various road surfaces (wavy pavement, potholes etc.); secondly we analyzed their impact on the application. The obtained results have proved the potential of these types of sensors for this kind of road engineering applications.
