Spatial coincidence modelling, automated database updating and data consistency in vector GIS. To address the latter aspect, procedures are formulated in the thesis for a consistent automated updating of a vector-structured database, using the DMMVM as a framework. Algorithms are provided for the automated update propagation such that Author: O. Kufoniyi.

Vector representation of data In the vector based model (), geospatial data is represented in the form of vector data, the basic units of spatial information are points, lines and of these units is composed simply as a series of one or more co-ordinate points, for example, a line is a collection of related points, and a polygon is a collection of related lines. GIS and databases)? • How could we enhance the use of spatial modelling in the calibration of components of larger application suites (spatial modelling tools as context-sensitive scriptable plug-ins)? • Perhaps rather than term the use of aspatial estimation techniques on spatial data potential misspeciﬁcation, could we not rather share withFile Size: 14KB.

This article provides a formal data model which allows to establish geometrical-topological integrity of areal objects in a geographical information system (GIS). The data model leads to an automatic tool able to check consistency of a given set of data and to avoid inconsistencies caused by updates of the database. To this end we start from the Cited by: 3D CityDB - A free 3D geo database to store, represent, and manage virtual 3D city models on top of a standard spatial relational database. The database model contains semantically rich, hierarchically structured, multi-scale urban objects facilitating complex GIS modeling and analysis tasks, far beyond visualization.
