NZARM Webinars - Understanding catchment mapping outputs using nationally available LiDAR data

The presentation will run through what the publicly available LiDAR datasets are and how they can be used to generate useful outputs. More specifically, the presentation will use the Taranaki region as an example and run through key hydrological & topographical mapping outputs including ephemeral flow paths and their contributing watersheds, erosion prone land and areas of high flow accumulation.

These outputs allow farmers, catchment managers, and council stakeholders to make mitigation decisions for better environmental outcomes. The webinar will also outline how advancements in ArcGIS tools can be incorporated into traditional web maps, making interpretation and decision-making possible by users in an internet browser rather than needing GIS software.


This type of spatial analysis enables outputs at a very detailed scale (up to 1m resolution) and is adaptable to suit a variety of use cases ranging from regional catchment planning to farm scale mitigation mapping. This methodology is also cost effective in comparison to other available tools and processes.
