This paper introduces spatial data mining technique especially decision tree algorithm applying to agriculture land grading. The idea is to combine spatial data mining/decision tree techniques with expert system techniques and apply them to establish an intelligent agriculture land grading information system. The author adopt decision tree c4.5 algorithm and implement with Mo2.0 and VC++6.0 to build...
With the rapid progress of economy, the land prices change quickly, thus demanding frequent update that is hard to accomplish in time. This paper addresses these problems by employing geographic information system (GIS) and spatial data mining (SDM) to dynamically grade and evaluate the prices of land parcels. In the paper, the author briefly introduced the integrated techniques between GIS and SDM,...
An earthquake is a calamity that can cause colossal damage to buildings, infrastructure, and environment, consequently leading to heavy casualties. It is therefore imperative for disaster relief agencies and civil protection bodies to assess the damage for planning purposes. Satellite remote sensing and geographic information systems can help prepare initial damage assessment maps. This examines the...
