This paper puts forwards a fast and collaborative search technology for massive and distributed spatial information based on grid dispatch and grid services, and the spatial search engine based on grid is designed. The service of grid dispatch for massive and distributed spatial information and grid map services are implemented by using gird development tool ProActive. The efficiency of massive spatial information search is promoted by parallel and collaborative search. The instantaneous and dynamic spatial information acquiring for 300 Chinese cities is also achieved. The engine provides a new technology for massive spatial information service.
