Digital Elevation Model Error in Terrain Analysis

A Clear-Sky Spectral Solar Radiation Model for Snow-Covered Mountainous Terrain

A dear-sky spectral solar radiation model for direct and diffuse fluxes, combined with topographic calculations from digital terrain data, computes either incident, net, or reflected solar radiation at any point on a snow surface in mountainous terrain. The radiation may be integrated over any wavelength range from 250 to 5000 nm, or over any time step. Atmospheric attenuation parameters are oz...

Presenting a Morphological Based Approach for Filtering The Point Cloud to Extract the Digital Terrain Model

The Digital terrain model is an important geospatial product used as the basis of many practical projects related to geospatial information. Nowadays, a dense point cloud can be generated using the LiDAR data. Actually, the acquired point cloud of the LiDAR, presents a digital surface model that contains ground and non-ground objects. The purpose of this paper is to present a new approach of ex...

High Resolution Modelling in Complex Terrain

During the past years the modelling community, both from the application and pure research perspectives, has been facing the challenge of high-resolution modelling in places with complex topography. In February 2012, as a result of the collaborative efforts of BOKU-Met, ARSC, IMG and the enthusiasm of the scientific community, the HiRCoT workshop was held in Vienna. HiRCoT objectives were: 1) T...
