ABSTRACT
This article describes use of archive aerial photographs for reconstruction of historical landscape for river development assessment. Photogrammetric methods are a well applicable tool for reconstruction of land-use change and digital surface model development. The software ERDAS 2013 enables fast and high-quality processing of sets of many archive aerial photographs without the need of data from the calibration protocol. Historical photographs from years 1938–1994 and actual orthophotomap from year 2010 were used for studying of the Ploucnice River channel change in the village Borecek close to the town Minon (Ceska Lipa district). Historical digital surface model reconstructed from the historical orthophotomaps with 60% overlaps were used for 3D visualisation of historical landscape. The digital terrain model from a laser scanning dataset was used for the accurate digital elevation model creation. The comparison of time series images shows three-dimensional land-use changes. The channel of Ploucnice River in all time horizons was digitized and then analysed by software ArcGIS Desktop 10.2. The study of river channel migration and lateral shifts of the channel in last 70 years were identified by use of spatial analysis, distance analysis and statistic assessments.
