For my geo-referenced project I used an image of Pompeii dated from 1832. The map details the archeological sight from what was currently found during the 1800s and 30s. The geo reference tool allows me to focus on a particular section of the map thus, allowing me to learn more and provide detail information on the area.
In terms of the course, large population centers are better mapped out with heat maps, strata maps, and anything requiring data.
no maps?
