Abstract
As many mapping organizations are updating geospatial databases with new data about our rapidly changing world, there are challenges of how to effectively and quickly to adjust the geometries so that there are no openings and overlaps due to variation between different versions of same data and neighboring features. The paper describes an approach of geospatial geometry adjustment basing on paradigm of point as being the simplest and smallest spatial primitive to manipulate and to define all geospatial data. Every unique identifiable spatial instance in form of point is given an identifier and it is this that is manipulated during geometry adjustment to transfer updates from the source/reference data to the data set being adjusted. This approach solves the issue of slivers and dangling which are always created during data merging and differences that are always brought into databases due to variations in data capture, storage, and manipulation.
