Digital Surface Model Generation based on Satellite Images
2019 International Conference on Information and Communication Technology Convergence (ICTC), 2019We propose an algorithm for computing digital surface model from several satellite images of same site. The proposed method is applicable not only to stereo pair images, but also to multi-mono images of the same region independently taken by different satellites at different times.

The Use of LiDAR in Digital Surface Modelling: Issues and Errors
Transactions in GIS, 2009AbstractModelling and extracting 3D geographical data presents numerous challenges that require continual research to attempt to evolve an efficient, reliable and accurate solution. LiDAR data capture and analysis has become a preferred acquisition choice for elevation data because the resulting quality and level of detail far exceeds traditional ...

Accurate Measurement and Digital Modelling of Complex Surface
Applied Mechanics and Materials, 2014Accurate measurement and modeling of complex surface is the foundation to precisely evaluate the error of complex surface. According to the NURBS method for rebuilding complex surface, a sampling data automatic replenishment method based on neural network is proposed and the sampling data with high precision is acquired.

Cosmo-Skymed for digital surface models
2012New, high-resolution space born sensors offer the possibility of near-real-time 3D Earth surface mapping. Acquiring and processing data rapidly and at low cost as well as being insusceptible to logistical problems or adverse weather conditions they offer great potential monitoring and managing natural disasters and emergencies.

Digital Surface Models for Building Extraction
1997This paper describes an approach to building extraction using Digital Surface Models (DSM) as input data. The approach consists of building detection and reconstruction using parametric and prismatic building models. The main focus is on the extraction of roof structures, an extension of the previously published work, as first step towards the ...

On the Accuracy of LiDAR Derived Digital Surface Models
2010The use of LiDAR data for developing high resolution topographic models of urban and rural areas has been widespread for more than a decade. In particular, the derived high resolution digital surface models (DSMs) are commonly used as input (among other models and parameters) for predicting the coverage of flooded regions.

On the Application of Digital Surface Representations in Hydrodynamic Modelling
1984For the purposes of modelling flow and transport processes in estuaries and the open sea, it is normal practice to evaluate variable quantities such as surface water levels, flow velocities and concentrations at nodes in a computational grid. These may either be of the rectilinear type, in which depths are defined at nodes in a square or rectangular ...

Digital Model of Switching Element Contact Surface
IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1979Real contacts adhere to one another only in separate elements of surface, creating so-called contact microfields. This is caused by a lack of perfectly smooth and planar contact elements. Irregularities of contact surfaces cause, in the initial phase of closing contacts, only small surfaces of contact and, moreover, not in many points.
