This project remapped the extent of Auckland’s wetlands by digitizing the 2010-2011 aerial imagery, as a baseline for further work to monitor change in wetland area over time. It involved using various spatial datasets and aerial imagery to identify and delineate wetland boundaries and classify wetlands by hydrological function (e.g. palustrine, estuarine etc.). A desktop method was chosen for the project as field surveys and remote sensing approaches were considered too intensive and less accurate for small wetlands.
