Creating a geological database using historic and contemporary information
summary
Hobby project compiles historic maps, WebODM orthophotos and modern LiDAR into a geoscience database served as QGIS vector layers and interpolated drillhole surfaces; orthophoto stitching and georeferencing work reliably, CPT logs produce modeled sand base contours that reveal tectonic tilting and ~3 mm/yr river downcutting, and mapped terraces, landslides and a mud‑volcano flow are digitized at about 1:2,000 effective detail for council and consultants.
