I prefer doing "drawing" tasks like digitising in CAD rather than GIS, simply because CAD was developed as a drafting tool while GIS is more limited on the drawing-tools front.Thats fair enough. My personal preference is for GIS over CAD however....mainly on the grounds that I believe that 'illustration' is the by product/end result of analysis and synthesis of data. I think that CAD at too early a stage in that process is indiscriminate. Everything gets digitised irrespective of value or sigificance. Whereas digitising into GIS, whilst perhaps less aesthetic, does allow the totality of the data to be considered (the 'image' is just the front end to any number of attribute values), analysed and synthesised ..........after which the relevant image can be exported to CAD and 'tidied up' for the final illustration if needed. In these days of watching every penny and getting full value for the archaeological buck that seems the efficient way to go....
My GIS by the way will georeference and overlay scanned raster image data without the need for any further digitisation at least at the primary data stage. As we routinely scan all plan and profile data as a security consideration that seems the ideal manner in which to minimise costs with no loss of capability. At the same time the raster data can be integrated with the site survey data from the TST that requires no further digitisation.
Is that capability possible in CAD?
