격자 자료의 리셈플링에 따른 정보손실 연구

Abstract

The past two decades have brought the rapid and quantitative growth of GIS with improved computer technology acquisition technology of spatial data. However, in respect to the qualitative aspects, which handling the spatial uncertainty, including error and accuracy of spatial data, the research and investment of GIS was held a little account. This results have influenced on a serious and adverse effect on the reliability of the GIS result. In this study, an estimate method of spatial uncertainty is presented, along with the spatial information loss that occurred among the resampling. The Root Means Square Error (RMSE), Variogram Modeling and the Spatial Autocorrelation (SAC) are presented and the Accumulative Probability Distribution Graph (APDG) is suggested as a method.
