Welcome to the University of Otago Matariki project 3D-Change Detection WebApp.
This is a web-GIS used to display elevation change data for Te Pātaka o Rākaihautū/Banks Peninsula between 1984 and 2018, as well as recent bathymetric survey in 2021.
The elevation change is displayed in the red to blue coloured layer on the right displayed onto the 2018 Digital Elevation Surface Model (DSM).
The left panel shows 1984 imagery draped onto 1984 photogrammetric DSM. Images from 1984/2019/2020/2023 can also be selected in either panels.
Interact with the data yourself: Turn layers on and off, pan and tilt the view with a three-button mouse.
