摘要

数字地形建模（DTM）是一种代表地形的地表计算模型，具有广泛的应用。这项工作提出了一种新的DTM方法，使用基于点的有限元方法（FEM）代替基于网格的方法。所提出的方法使用的点是通过卫星图像捕获的数据获得的。大多数方法都需要在地形曲面上预先计算网格。我们的方法克服了网格步骤，因此建模过程非常快速。

DIGITAL TERRAIN MODELING USING FINITE ELEMENT METHODS MESHLESS

Digital Terrain Modeling (DTM) is a computational model of the earth surface that represents relief and it has a wide range of applications. This work proposes a new approach to DTM using the Finite Element Method (FEM) point-based instead of mesh-based. The points used by the proposed methodology were obtained by data captured by satellite images. The most methods require the precomputation of a mesh on the surface of the terrain. Our methodology overcomes the mesh step, so the modeling process is very fast.

期刊介绍： Journal of Urban and Environmental Engineering (JUEE) provides a forum for original papers and for the exchange of information and views on significant developments in urban and environmental engineering worldwide. The scope of the journal includes: (a) Water Resources and Waste Management [...] (b) Constructions and Environment[...] (c) Urban Design[...] (d) Transportation Engineering[...] The Editors welcome original papers, scientific notes and discussions, in English, in those and related topics. All papers submitted to the Journal are peer reviewed by an international panel of Associate Editors and other experts. Authors are encouraged to suggest potential referees with their submission. Authors will have to confirm that the work, or any part of it, has not been published before and is not presently being considered for publication elsewhere.
