On the Quality of Object Classification and Automated Building Modelling Based on Laserscanning Data
In this paper, techniques for an automated extraction, classification and modelling of 3D objects will be presented. They use solely laserscanning derived digital elevation models as data basis. Trees, buildings and terrain objects are detected and classified. Firstly, a special region growing algorithm segments 3D objects on the terrain surface. Object specific features are extracted inside th...
متن کاملA fuzzy approach to visibility maps creation over digital terrains
The construction of inter-visibility models for a terrain is an important tool for environmental and animal studies. E-cient crisp algorithms are known to address this problem directly on a raster digital elevation map (DEM) of the study area. Randomness plays an important role: several factors like vegetation, height of the observer, presence of unmapped human artifacts, etc. cannot be modeled...
متن کامل3D Path planning using a fuzzy logic navigational map for Planetary Surface Rovers
This work proposes an innovative app navigation path-planning problem exploration rovers by including terrain characteristics. The objective is to enhance the typical 2D arithmetical cost function by adding 3D information computed from the laser-scanned terrain such as terrain height, slopes, shadows, orientation and terrain roughness. This paper describes the algorithm developed by UPM and GMV...
متن کاملClassification of Digital Terrain Models Through Fuzzy Clustering: An Application
Experts classifications of spatial data are strongly affected by subjectivity and rigidity of rules. They do not take into account, in a quantitative way, the overlap of classes and as a major consequence, their classifications are often not reproducibles. To overcome this subjectivity, exploratory techniques can suggest a coherent set of rules that will produce suitable polythetic and overlapp...
متن کاملTerrain Analysis Using Digital Elevation Models in Hydrology
This paper describes methods that use digital elevation models (DEMs) in hydrology, implemented as an ArcGIS toolbar using Visual Basic and the ESRI object library. I describe generalized channel network delineation to objectively estimate drainage density and by using terrain curvature accommodate spatially variable drainage density. The multiple flow direction field determined from a DEM also...
