On　the　basis　of　analyzing　the　special　requirements　of　multi-source　image　data　managment,　we　proposed　to　store　and　manage　image　data　and　its　metadata　integratively　in　object-rational　database.　In　this　paper,　first　we　studied　the　storage　model　based　on　GeoRaster　and　the　key　technologies　about　image　blocking,　compressing,　pyramid　construction　and　spatial　indexing.　Then　proposed　a　architecture　of　multi-source　image　database　system.　Finally　based　on　GDAL　and　GeoRaster,　we　implemented　an　image　database　system　of　Client/Server　structure　for　storing,　querying　and　managing　Remote　Sensing　data.　©　2010　IEEE.
