Transcript of Lidar - a different point of view

Lidar is intense - a small sample around Port Fairy creates a ~700Mb terrain model!

How do we make this useful and manageable?

One solution:
create a database of coastal profiles (x-sections) attributed with information useful to management. Coastal
PROFILES Where is Port Fairy? SW Victoria, Australia To make profiling of "useful" we have:
fully automated the process
added location specific information
provided the profiles as a database (vectors) enabling any GIS to display or query the information
this example illustrates coastal assets in the context of terrain and other readily available spatial information
A short video is provided to illustrate the result Coastal
LIDAR "a slice of the coast"... Profiles are attributed with
relevant management information Fusion of multiple data sources into a single database X-sections
fusing Lidar-derived high resolution terrain models with planning/resource information - a story of accessiblity Lidar derived terrain models can be very large datasets
This can be problematic for use in planning and NRM
Integration of other resource and management information with terrain models as raster data is difficult Lidar is intense - its comes with both surface terrain models and 1st return models that give the potential for deriving vegetation/structure profiles.
