FGI releases hyperspectral Terrestrial Laser Scanning dataset as open data

Posted on

Finnish Geospatial Research Institute (FGI) at the National Land Survey of Finland has released a hyperspectral Terrestrial Laser Scanning (TLS) dataset as open data. Each point in the laser scanning point cloud contains colour information from several different wavelengths. Ordinary laser scanners only contain colour information from one wavelength.

Unique data

The laser scanning point cloud dataset consists of 30 individual scans collected as a time series covering a 26-hour time frame. The data was collected in September 2013 using FGI’s hyperspectral laser scanner (FGI HSL), which has been developed and built at the FGI. Each point in the laser scanning point cloud carries information about its spatial location and intensities of seven separate wavelength channels. Currently, this dataset is the only one of its kind.

Dataset available via Etsin

The dataset is available via the Etsin research data finding service provided by the Finnish Ministry of Education and Culture. Datasets are provided in .laz format and published under the Creative Commons Attribution 4.0 International License (CC-BY-40).
