Contour_1m_Simple
These contours are dynamically generated from a Digital Elevation Model (DEM) based on LIDAR data collected between 2019 and 2022 by Bay of Plenty Regional Council (BOPRC) and Land Information New Zealand (LINZ).
Processing Notes: Contours have been simplified using FME Generalizer transformer with Wang (Generalize) algorithm and 1-meter generalization tolerance to optimize performance while maintaining cartographic accuracy. Bathymetry data from Bay of Plenty Regional Council Toi Moana has been integrated into this dataset to provide comprehensive elevation coverage including underwater terrain.
