| Popis: | Error in radar satellite orbit determination is a common problem in radar interferometry (INSAR). For example, when we try to locate a radar test site with known geographic coordinates using the geocoding information in SLC (the latitude and longitude of the four image corners), the location is well away from the true position. Another example is when there is a significant disturbance in the differential INSAR result, we sometimes are not sure whether it is from ground deformation or atmospheric heterogeneity. Even after these are corrected, we need to export the INSAR results to a GIS format so that they can be overlaid as layers over orthophotos and mine plans (in the case of mining subsidence) in order to interpret the results. Therefore, it is proposed to use both GPS and GIS to assist radar interferometry. Results are presented with an application to monitoring subsidence due to underground mining southwest of Sydney, Australia. |
