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.
