EXTENSION OF RCC TOPOLOGICAL RELATIONS FOR 3D COMPLEX OBJECTS COMPONENTS EXTRACTED FROM 3D LIDAR POINT CLOUDS
Topological relations planar regions components automatic 3D modelling point cloud
2016/7/27
Topological relations are fundamental for qualitative description, querying and analysis of a 3D scene. Although topological relations for 2D objects have been extensively studied and implemented in G...
Buhom: A Program for Enhancement of Geometric Topologic Consistency of Building Objects
generalization building generalization digitizing errors vector data
2015/7/6
Vector data is captured using various methods, e.g. manual digitizing, automatic vectorization etc. Errors or inconsistencies, e.g.
self-cutting polygons, identical points etc, can not be avoided, ev...
A Gis Database for Time-evolving Spatial Objects
Spatial Information Sciences Databases Modelling Query GIS
2015/7/6
In this paper, we have designed a data model for moving objects and implemented it. The moving objects are time-evolving spatial
objects, that is, their geometries are dynamically changed as time var...
