Combining geostatistical techniques and geographic information system may not only provide the basic functions of geographic information system, but also improve the functions of spatial information analysis and estimation to realize spatial variations, dependences, estimation and simulation of spatial data, especially to improve the ability of decision making support of geographic information system. Therefore, in this project, we first review the geostatistical methods and algorithms to select suitable, useful and applicable geostatistical methods which are the bases of the geostatistical components of the geographic information system SuperGIS. A number of test examples also set up to evaluate the performances of the components comparing to most popular geostatistical software. SuperGeo Technologies Inc. performed the coding the algorithm components, user interface and functional modules. The performances of these codes reported and feedback to designer in the SuperGeo Inc.. Final, this team produces high performance geostaistical components for SuperGoe which is a native Geographic information system in Taiwan.application/pdf1244786 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所地理統計地理資訊系統空間結構地理統計運算方法地理統計運算元件GeostatisticsGeographic Information SystemSpatial StructureGeostatistical methodsGeostatistical algorithm components行政院國家科學委員會專題研究計畫成果報告:地理資訊系統SuperGIS 之地理統計演算元件平台技術開發reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/29736/1/932415H002071CC3.pdf
