In order to effectively organize and manage the obtained spatial data, this paper studies the integrating access method of network spatial data. Analysis of the integrating access technology of spatial data distributed on network, builds the network spatial data integrating access framework based on service-oriented architecture (SOA) architecture, puts forward a method of organizing and scheduling the multi-scale spatial data, designs a network spatial data access protocol, designs and realizes a method based on MapReduce calculation model which parallel build the mass remote sensing image index, finally constructs a prototype system to validate the proposed methods. Experiment results show that the method realizes the massive spatial data quickly preprocessing and integrating access under the network environment, verify the feasibility of integrating access.
