The document authorization and distribution of spatial data is the most significant arena for archaeologists. Digital concept concerning site and excavation unit level mapping, provides huge advantages in the field of archaeology. In comparison with a manual approach, it provides more precise and quick method.
PhotoScan Pro and PhotoModeler Scanner produce a 2D georeferenced orthorectified photograph (hereafter known as
orthophoto) output in which a
3D model is transformed into a spatially perfect 2D rendering of the modeled space. The images function like a best platform where drafters can make digital maps.
It is examined from the field that maps of scales encompassing an excavation unit to a complete site generated with orthophotos through an image-based 3D modeling software, are more authentic with respect to the maps made by applying manual drafting processes.
If a drafter comes up with a digital cartographic approach established in the application of
orthophotos exported from an image-based
3D modeling software, he will be able to produce an archaeological mapping containing a well-organized timing as well as exceptional spatial accuracy.
The spatial reliability of image-based 3D models can be treated as a perfect system for a 3D excavation recording process, since most of the software packages allow area and volume calculation functions.
