I am a GIS Analyst with a background in archaeology, computer science and general electronic tinkering. I generally know enough to get in way over my head and then work my way back out.

comment How to Deal with Overlapping Coordinates in Statistical Analysis
My point is that archaeological sites always have area. Points never do. So, by using a point to represent an archaeological site you may be incorrectly limiting the number of other variables that your site is associated with. For example, the relevant variable may be a range of elevations, not a single elevation, and by assigning each site a specific elevation from a point you are obscuring that. Choosing to use points or polygons is a choice that should include consideration of the scale of your analysis, your research question, and what other variables you are considering.

comment How to Deal with Overlapping Coordinates in Statistical Analysis
First off, I'm an archaeologist in North America, I have no experience with European archaeology. That said, I would think that you could use the site reports and maps to digitize the area for each site, perhaps even fairly accurately. If you don't have the maps, then some manner of polygon that relates back to the size described in the report would likely suffice.

comment Computing distance of a georeferenced .jpg to each polygon (town) in a shapefile
Georeferencing the image simply places it in space relative to other data. It's still a raster, not a vector. To get the road and cities into a vector format you need to digitize the line and the points for the city. The link Fezter provided is probably the best place to start.

comment Strange things are afoot with the "Eliminate Polygon Parts' tool
I've encountered this error when coming at if from arcpy and the ArcGIS tool. Regarding the matter of the area, the polygon in question is about 1,000,000 square meters, so specifying an area condition at 1 billion is actually a larger area than the total polygon area.

comment using the “freehand” construction tool
That's a good one too - I really like using undo because you don't have to click anywhere. If you just screw up and click in totally the wrong spot you can just hit ctrl-z and carry on.
