The Construction of the Animal Husbandry Information System Based on the Topological Relation

The research aims to merge the sections of geographic information distribution of the large-scale farms information monitoring system and the farming enterprises filing system which under the Animal Husbandry Bureau in Heilongjiang Province as a Geographic Information System (GIS) that based on the map conflation technology of topological relation. Applying a variety of algorithms of points, lines, surfaces to this study, and using optimized "Spider code" and matching algorithm based on area overlay rate to solve the map database conflation problem of two different sources but consistent geographic target.
