Contributions to a quality description of areal objects in spatial data sets
spatial data quality comparison of spatial entities building extraction
2016/5/20
In this paper we present a quality evaluation of two-dimensional building acquisition. We propose methods for identification and quantifi-cation of differences between independently acquired regions, ...
The determination of the spatial extent of geo-objects is generally approached through the boundaries or more precisely through the position of the boundary points. The analysis of the geometric uncer...
LOGICAL CONSISTENCY FOR VAGUE SPATIOTEMPORAL OBJECTS AND RELATIONS
spatio–temporal vagueness spatio–temporal databases spatial data quality logical consistency integrity constraints
2015/9/28
Vagueness is often considered as an inherent property of spatiotemporal phenomena. In order to reduce this vagueness, integrity constraints should be defined to improve logical consistency of spatiote...
Fusion, Interpretation and Combination of Geodata for the Extraction of Topographic Objects

2015/5/26
The extraction of objects from images and laser scans has been a topic of research for years. Nowadays, with new
services expected, especially in the area of navigation systems, location based servic...

APPROACH TO ACCURATE PHOTOREALISTIC MODEL GENERATION FOR COMPLEX 3D OBJECTS
photogrammetry spatial data surface reconstruction textures mapping orthophoto VR
2015/1/6
Due to the progress in computers and sensors development the number of virtual reality application (VR) grows significantly. Different sensors and techniques such as laser range finders, still and vid...
TERRASAR-X AND RAPIDEYE DATA FOR THE PARAMETERISATION OF RELATIONAL CHARACTERISTICS OF URBAN ATKIS DLM OBJECTS
Urban land use object-based image analysis RapidEye
2014/6/5
This work presents a multi-sensor data analysis concept for the parameterisation of urban landuse in comparison to ATKIS DLM
reference objects (digital landscape model). An object based top-down app...
Approximate geometric reasoning with extended geographic objects
Uncertainties in spatial data qualitative spatial reasoning fuzzy logic axiomatic geometry
2016/4/11
The article presents a conceptual framework for formal geometric reasoning with extended objects in the context of vernacular geography. Vernacular geography is concerned with place names and their re...
