[blog post]: Field trip to Garopaba    


Back in 2010 we acquired an airborne LiDAR survey of the Garopaba Dune Field, located in southern Brazil about 45km south of Florianópolis (see it in Google Maps), as part of the research grant FAPESP #2009/17675-5. We created some nice DTMs and evaluated how the calculated volume of sand would change with different spatial resolutions of the DTM (Grohmann & Sawakuchi 2013).

In 2019 we went back to create a new DTM, this time using TLS and SfM-MVS. You can check the results in the paper published in Computers & Geosciences (also freely availabe as a preprint at arXiv)
