Description

This dataset contains the inputs used for Structure from Motion Multiview Stereo photogrammetry processing for the year 1967 and 1984 i.e Unprocessed scanned historical aerial Photographs, camera position coordinates, flight index and Ground Control Points. All the scanned historical aerial photographs data are in TIFF format except four photographs in JPEG format under a zipped folder ("1967_Scanned_HAPs_Part1.7z and 1967_Scanned_HAPs_Part2.7z" for the 1967 Historical Aerial Photographs and "1984_Scanned_HAPs_Part1.7z and 1984_Scanned_HAPs_Part2.7z" for the 1984  Historical Aerial Photographs). The "Flight_Index.Zip" contains shapefiles of the camera position and polygon of consecutive aerial photograph index; "GCP.Zip" contains text file of the GCPs used for the 1967 and 1984; and "Camera_Position.Zip" contains the file of the camera position (Label, Easting, Northing and Altitude) of each historical aerial photographs. 

The results of the above dataset could be accessible on Zenodo repository "10.5281/zenodo.7269999".

Anyone can reuse the presented dataset to produce DEMs and Orthomosaics; and use for the following application  areas:

1. watershed management

2. analyses of historical landscape change

3. detailed mapping and analyses of geological and archaeological features, as well as natural resources

4. analyses of geomorphological processes

5. socioecological patterns and dynamics

6. modelling and planning for telecommunications 

7. biodiversity research. 

 

Notes

This research was funded by the German Research Council (DFG) in the framework of the joint Ethio-European Research Unit 2358 "The Mountain Exile Hypothesis: how humans benefited from and re-shaped African high-altitude ecosystems during Quaternary climatic changes". We thank the Geospatial Information Institute of Ethiopia for provided us the necessary data and documents; and the Ethiopian Wildlife Conservation Authority, the Philipps University of Marburg, the Ethiopian Wolf Project, and the Bale Mountains National Park for their cooperation and permission to conduct field work. We also very much appreciate the support of Mohammed Kedir, Hussein, Gash Kasim, Awol Assefa, Sofia, Wege Abebe, and Katinka Thielsen, without whom it would not have been possible to do the field work in the Bale Mountains. We thank Spaska Forteva for her help in arranging lab facilities.
