This work is based on 5 new ground control points, defining a polygonal ring, surrounding the object, which is polar connected to 
the global coordinate system via 3 control points. In addition 4 points, defining the axis of the object are polar connected to the 
polygonal points. 
This allows to calculate global coordinates for all controlpoints, including the 4 points defining the axis of the object. Knowing the 
global coordinates for the 4 axis points of the object, the local coordinates for this 4 axis points counting from the center of the object 
and along the object axis are elementary determined. Now a coordinate transformation based on the 4 axis points allows to calculate 
the local coordinates for all controlpoints. From there the grid will be determined and set out in the local coordinate system, see

2. TRADITIONAL SKETCHES OF ARCHAEOLOGISTS VERSUS (EXTREMELY) LARGE SCALE PHOTOMAPS 
A real obstacle for a broad application of single images in Archaeology is the anachronistic competition between objective 
photogrammetric mapping and subjective Archaeologic interpretation. 
As a matter of fact the typical today's surveying results of Archaeologists are still manual sketches in the scale 1:20, where details are 
roughly measured and even estimated within a 4 x 4 m grid! 
State of the art results of the surveying of the ground situation of objects showing partly plain surfaces are rectifications based on 
extremely low aerial photography, imaging object parts together with at least 4 corresponding controlpoints. 
Of course, partly stereo Photogrammetry can be required. It would already be a big progress, if the archaeologists would at least use 
the high resolution photography for mapping purposes! Surveyors should refuse, promoting manual sketches of any kind, as they are 
not state of the art. It is liked to emphasize, the alleged superior of manual sketches, supposed to be proofed by the comparison of 
detailed sketches with poor photographs, is completely nonsense and has nothing to do with the today's ability of photographic 
techniques.
