Abstract
To solve the problem of information island. Established the cluster spatial database in a distributed network environment. Built a unified spatial index system based on Hilbert space-filling curve scan matrix, to get one-dimensional mapping between Hilbert space arrangement code and spatial index information. Realized spatial data rapidly index across spatial databases. Experiments show that the system directly to a relational database table through the scales of operation and maintenance, as much as possible to avoid the call to the system relies on the development of the ArcGIS platform package ArcObjects correlation function, built a key spatial index system and a good support for data sharing.
