Abstract
Elevation error in the Intermap x-band airborne RADAR DTM data set is defined in a 260-hectare mixed land cover area using external dual-frequency GPS and bare-earth LiDAR point-cloud validation data. Absolute elevation error is reported globally, and within land cover classes characterised by distinctive vegetation canopy densities and depths that are considered to have the potential to affect x-band DTM elevation error in distinctive ways. Observed global and land cover specific elevation errors are subsequently compared with an external study where land cover dependent errors were quantified within four LiDAR data sets that overlapped the RADAR DTM validation area. The results of these absolute and comparative results are subsequently used to make recommendations regarding the potential of Intermap bare-earth RADAR DTM data in environmental modelling applications elsewhere, and the scope for using the data in conjunction with, and as an alternative to airborne LiDAR data is discussed.
