Abstract: In order to overcome the problem of poor data coordination existing in the existing geographic information integration model, a new regional sub-metre high score remote sensing geographic information integration model construction method is proposed. The application of distributed integration technology to build a regional sub-metre level high score remote sensing geographic information integration model. Joint processing of images, in the integrated environment of GIS and RS, transform the independent variables in the data into a vector grid integrated structure, establish a joint index format based on B+ tree index and quadtree index, complete the RS and GIS model build. Experimental results show that the model can apply street, city name, and place type keywords, with better integrated indexing effect and higher data coordination.

Keywords: remote sensing geographic information; integrated model; grid; joint index.
