Dear Sir/Madam
I am an exploration geologist with a large experience in GIS&Remote Sensing.
This is including digitizing, at a high accuracy, of various features like nature, morphological or man made.
The works were made in various coordinates systems, like local or WGS 84.
As a plus, I can find and use other free aerial imagery which some time is at a better resolution than Google Earth.
Of course, the file (kml or at the specific demand) will be provided in a common WGS84 coordinates system.
Hooping that mt experience will be useful for your project I remain at your disposal with any other details.
Kind regards,
