For some time now, I have catalogued (mostly) Roman features I encountered in my studies, first in GoogleEarth, later I switched to QGIS, and over time produced this database. It was always meant for my personal use, so it does not live up to academic standards - most sites are only a rough localisation, several km off the actual site; vague literature quotes were often not checked for accuracy. Still, I upload it here to see if anyone is nevertheless interested in this data; if you are, I'd be happy to hear about it, send you more data layers, receive addenda, corrections or questions.
