In this paper, we investigated how survey configuration and the type of interpolation method can affect the accuracy of river flow simulations that utilize LIDAR DTM integrated with interpolated river...
HEIGHT TEXTURE OF LOW VEGETATION IN AIRBORNE LASER SCANNER DATA AND ITS POTENTIAL FOR DTM CORRECTION
airborne laser scanning vegetation texture DEM/DTM correction
font style='font-size:12px;'>
2015/8/13
The influence of low vegetation on laser scanning and its disturbing effect (a systematic positive height shift) during DTM generation
is well recognized. Based on our experience in a previous study...
LASER DTM GENERATION FOR SOUTH-TYROL AND 3D-VISUALIZATION

2015/8/13
In the past years laser scanner data has established itself as an accurate and reliable data basis for many applications. Highly accurate
digital terrain models (DTM) can be derived by filtering las...
Dense DTM Generalization Aided by Roads Extracted from LiDAR Data
LiDAR High Resolution Extraction DTM Generalization road detection Representation
font style='font-size:12px;'>
2015/8/13
The paper concerns the generalization of DTM extracted from LiDAR data. The essence of generalization is reducing details while
enhancing important features at the same time; so for the purpose of te...
Explicit solution of axisymmetric stagnation flow towards a shrinking sheet by DTM-Pade
Differential transform method Padé Approximant
font style='font-size:12px;'>
