The Method of GIS Platform Based on Feature-oriented Object Tree(FOOT) and Four Tier Architecture[J]. Journal of Image and Graphics, 2004, 9(9): 1135. DOI: 10.11834/jig.200409219.
A geo-spatial data model of feature-oriented object tree (FOOT) is presented. Spatial partitioning
spatial clustering and spatial indexing were emphatically discussed. Database services
application interface and application services in Four Tier Architecture are analyzed. By the spatial data organization and systematic architecture
function modules with massive spatial database management for the system are introduced. And also detailed object logic relation for the modules were explained. At last
on the base of design for the FOOT model and key technique of systematic implementation
an example of massive spatial database platform running in Linux and Oracle was given. The testing with 30 GB spatial data shows that the systematic main aims implement in feature-object spatial data organizing
integrative massive spatial data management and distributed spatial data computing. By the uploading national land use map and national county-administration map of 1∶400
the display is rapid. the efficiency of map windowing
spatial overlaying and buffer analyzing are very high
