Model Parent-Child Relationships between Lines and Parcels

摘要

In land use change survey, roads broadening change the area of residences on both sides of the roads, and area statistics of these two types of land use change accordingly. But these changes can not be detected on the map since many area entities that are narrow and long in real world, such as streets and rivers, are typically represented as lines on the map. It's important to find some new methods to analyze and represent these kinds of changes on the map so as to statistic area values of each kind of land use change in land administration domain. So the author analyzes the possible change of lines(on the map) in land use change survey and spatio-temporal relations between lines and their parents, and then deduces a decision rule for detecting parent-child relationships between lines and parcels, which helps to find the predecessors or successors of a given line/parcel by spatio-temporal query.
