The accuracy of DEM95 is affected by the quality and parameters of the aerial photos taken, the height of the flight, the topographic characteristics of the area, the status and type of the vegetation cover as well as the human factor during the photogrammetric evaluation. The potential limitations of these data could be a lack of sensitivity to the variation in terrain surface due to the presence of trees and areas of steeper slopes.
Overall, the results obtained in this study indicate that the accuracy DEM95 is comparable to DEMs extracted with photogrammetric techniques from previous studies, and strongly encourage the use of archival materials to improve the geomorphological studies. Developments on data acquisition and processing software allows the reuse and enhancement of historical data for DEM generation, leading to better and faster results
