Pre-dam valley reconstruction based on archival spatial data sources – Methods, accuracy and 3D printing possibilities

Popis výsledku v původním jazyce

Archival spatial data sources (maps, aerial photographs) allows reconstruction and 3D visualization of landscapes that have been altered by human activity. This paper is dedicated to the reconstruction of the 300 km long pre-dam valley of the Vltava River (Czech Republic, Europe) inundated by nine reservoirs built in-between 1930 and 1992. We use methods based on archival aerial photographs and old maps for the purposes of the pre-dam georelief reconstruction – their use is exceptional as the total area subject to the reconstruction is 1670 km 2 . Based on our results, we preferred old maps for terrain reconstruction. The map series “State Map Derived 1:5000” released between 1950 and 1959 was chosen as the most suitable data source for the pre-dam valley reconstruction as this map series covers the whole area of interest with elevation information. On the basis of the processed maps, more than 26 000 km of contour lines were derived by semi-automatic vectorisation. The resulting pre-dam digital elevation model was created by a combination of interpolation techniques. We demonstrated that the methods used for the georelief reconstruction under standard conditions should be used carefully while working with such large areas. A geostatistical analysis was performed to check the accuracy of the resulting digital elevation model. The differences between the model and LiDAR surveyed data were analyzed from three points of view: spatial autocorrelation, normality, and elevation stability. Several methods of 3D printing were tested to produce a realistic 3D model with a texture applied. The CNC milling method was used to produce 3D models of three reservoirs in scale 1:8000 and 1:6000.
