在过去的三十年里，地理信息系统技术已经从计算机制图发展到空间数据库管理，最近又发展到定量的地图分析和建模。然而，大多数应用程序仍然依赖于视觉分析来确定地图内部和地图之间的相似性。这项研究的目的是用不同的方法比较根据河口沉积物特征指标计算的均质区域图。这些地图使用三种不同的内插方法定义。不同的Kappa统计量、可视地图覆盖或因偶然性、数量和位置引起的一致和不一致的成分被用于单元格和/或邻域(硬和软)地图的比较。虽然这三种方法是用不同的统计技术计算的，但它们的结果是相似的，支持选择任何一种方法作为河口的管理单元。因此，选择其中一种方法的意义就降低了。
In the past thirty years GIS technology has progressed from computer mapping to spatial database management, and more recently, to quantitative map analysis and modeling. However, most applications still rely on visual analysis for determining similarity within and among maps. The aim of this study is to compare maps of homogenous areas computed from estuarine sediment characterization indicators, using different approaches. These maps were defined using three different interpolation methods. Different Kappa statistics, visual map overlays or components of agreement and disagreement due to chance, quantity and location were used for single cell and/or neighborhood (hard and soft) map comparison. Although the three methods were computed with different statistical techniques, their results are similar, supporting the choice of any of the methods as equivalent and thus of equal value to be used as management units of the estuary. Hence the significance of choosing one of the methods is reduced.
