There are no geological mapping projects underway or imminent in the Hamilton area. Previously completed maps include:

2005/2018: QMAP 1:250 000 geological map

For wider and more generalised geological context of the Hamilton area, a 1:250 000 geological map was printed with accompanying explanatory text. Digital GIS and image versions of the map are available on DVD. The digital version has since been updated in a national GIS dataset at that nominal scale. The underlying GIS datasets have rich feature attributes. See also Web Resources below.
