Digital Terrain Model Data Structures
This paper describes pertinent digital terrain model data structures, namely, grid/raster, quadtree, and triangular irregular network. A basic concept of DIM data structure is also explained. The aspects of TIN storage, TIN data structure conversion, advantages and disadvantages of each structure are discussed. A complete data structure conversion program is also presented. n. 1.0 INTRODUCTION ...
متن کاملCombined analysis of digital terrain models and remotely sensed data in landscape investigations
This article presents a review of the combined analysis of digital terrain models (DTMs) and remotely sensed data in landscape investigations. The utilization of remotely sensed data with DTMs has become an important trend in geomatics in the past two decades. Models of more than ten quantitative topographic variables are employed as ancillary data in the treatment of images. The article review...
متن کاملDigital Terrain Models in Dense Urban Areas
In this paper we consider the problem of DTM extraction in dense urban areas. To this aim, we need valuable and reliable data in the tiny open areas among buildings, and a suitable algorithm to reconstruct the terrain discarding these same structures. So, we compare first LIDAR and aerial photogrammetry by evaluating the relative accuracy of the three-dimensional reconstructed surface in the sm...
متن کاملVisualization of digital terrain and landscape data - a manual
Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this visualization of digital terrain and landscape data a manual, how can you bargain with ...
متن کاملAntialiasing in Raycasting Digital Terrain Models
We may use ray-casting methods to render terrain from digital terrain models. In this paper we enhance a terrain renderer in several ways, including application of antialiasing techniques. Also we examine various aspects of antialiasing in terrain rendering. We summarize surface and color reconstruction models, and discuss several vertical antialiasing techniques, including supersampling and ar...
