This is just a first start. I have many more aerial photographs, GPS coordinates, and tracks. But I’m not into mapping (yet). The question is, if I deliver the raw data, would anybody else with experience in mapping do that part?
Here is the first example, a very important petrol station in upcountry Kenya, important, because it is far and wide the last one on the way north.
Name of the petrol station: Mogotio (after the nearby settlement of the same name)
The aerial photograph: http://michna.com/kenya2009/images/p1110056p.jpg
The travel report that contains it: http://michna.com/kenya2009/#tb
The coordinates of the center of the petrol station: S0.02086 E35.96450 or S0 01.252 E35 57.870
A higher-resolution photo is also available. I will email it on request.
The source of the information is myself. I took the aerial photograph, I regularly fill my tank there, and I took the GPS coordinates. I am willing to release the photo unconditionally into the public domain.
