7. What Can be created from the aerial data DEM/ DTM / DCM /Crown
Sizes Calculating tree height from the laser altimeter. The
profiling laser fires 248 times per second and records alternating
first and last returns from each pulse, modelling both the canopy
surface from the first returns and the underlying topography
whenever a last return can penetrate through to the ground.As a
result, the approximate height of trees in a forest stand can be
determined from a DEM of the canopy surface (DCM), even when a
correspondingly accurate DEM of the ground is not available, by
examining the underlying profile of laser data. Combined with DEM
or Stereo Analyst measurements of crown diameter, this data
produces a simple model of the forest stand that can be used to
estimate growth, standing biomass, and tree dimensions. Kick-off

Delivering Geohazard/Geomorphological Models Mountain Forestry A
number of European programmes have assessed at a large scale
geohazards (mostly landslides), for example Terrafirma, LSI, SAFER
LIM and RLM, SLAM, PREVIEW, SAR.net, SAR.net2, DORIS and SafeLand
Use of UAV and other data sets gathered as part of this programme
will allow more detailed mapping and practical assessment of
geohazard with respect to local mountain forestry activity number
of Geohazard/geomorphological constraints include for example:
landslide, rockfall, soft ground, steep/rocky terrain, general
groundtargets hydrological features, glacial conditions, features
visible, gradie By quantifying the geohazard the appropriate
forestry management technique can be nt of applied to optimise
mountain forestry opportunitiessurface The use of particular DEM
and aerial imagery in combination with localised groundproofing
would allow a rapid interpretation of geomorphology and
identification of geohazard and terrain evaluation Several
approaches to geohazard mapping are available, as follows: Kick-off
