The description of Historical image
The aerial photographs of different times record the geomorphology of the time, reflecting the record of the culture at that time, and provided the most realistic evidence for us to explore the changes of terrain and social culture in the past. LIDAR technology has continued to think the historical data value and its processing analysis, and try to produce them to the greatest value.
Analysis of historical image processing
Historical astronomical images record the characteristics of the terrain and geography. Besides showing the image of terrain information, we can also use the overlapping images of the three-dimensional image on the production of numerical terrain model.
Comparison of Historical Aerial Images
Red and blue stereotypes can be used with the ground information, for interpretation of terrain changes and building height measurement, for example: illegal construction and determination.
