Monitoring of Earth Surface Motion and Geomorphologic Processes by Optical Image Correlation

摘要: Abstract: The detection and quantification of motion the Earth’s surface are essential for study understanding many geomorphological geological processes such as tectonics, earthquakes, landslides ice glaciers, to name a few. direct measurement earth displacement deformation falls into larger discipline geodesy, which also includes studies shape, movement gravitational field Earth. Traditional surveying methods measure comprise use theodolites, electronic distance meters, total stations nowadays typically global navigation satellite systems (GNSS). While can provide very precise point-wise measurements, aerial remote sensing techniques generally more suitable measuring dense fields and/or inaccessible areas.
