The Construction of the Animal Husbandry Information System Based on the Technology of Map Conflation
International Journal of Smart Home
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 are 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
... overlay rate to solve the map database conflation problem of two different sources but consistent geographic target. It not only improves the map accuracy and consistency, but also adds new space characteristics, and updates attribute information which associated with dataset spatial characteristics. It makes the personnel at all levels in the Animal Husbandry Bureau in Heilongjiang Province realize information sharing. It is conductive to promote the work of staff at all levels and provide decision support of data to the Animal Husbandry Bureau in Heilongjiang Province. above two systems obtained the geographical target of Heilongjiang repeatedly. It leads to the multiple expressions of the same geographical target in different datasets, and makes it difficult to share information between staffs at all levels in the Animal Husbandry Bureau. In order to improve the accuracy and consistency of geospatial data, adding new spatial entities, updating properties which combined with spatial characteristics of the dataset, saving the resource of the platform of GIS SERVER, and reducing the cost of system development this study aims to merge these two systems. The combined system is called Heilongjiang animal husbandry information system. The key is on the consolidation of geographic information systems' modules. This study use the map conflation technology of topological relation, that is applying a variety of algorithms of points, lines, surfaces to this study, which makes it more convenient and direct for the staffs at all levels in the A nimal Husbandry Bureau to manage all types of large-scale farms. It also provides decision support of data to the Animal Husbandry Bureau in Heilongjiang Province.
