Abstract
In 2008–2010 the LiDAR data were captured for all territory of Lithuania.
According to the technical requirements, the density of the points approximately
is 4 points in 1 sq. m. This results in a very high resolution data set with a
good spatial distribution. As was declared in technical requirements the accuracy
of any LiDAR data point should be not worse than 15 cm in height component, and
not worse than 30 cm in plane position. We were investigating the accuracy of
the Digital Terrain Model, based on this LiDAR data set. The additional data
of the first order vertical network points, gravity reference network points
and geodetic reference network points were applied.
Keywords: LiDAR; Digital Terrain Model; normal height.
