| Abstract: | This paper presents the spatial implementation of the karst feature database (KFD) of Minnesota in a GIS environment. ESRI’s
ArcInfo and ArcView GIS packages were used to analyze and manipulate the spatial operations of the KFD of Minnesota. Spatial
operations were classified into three data manipulation categories: single layer operation, multiple layer operation, and
other spatial transformation in the KFD. Most of the spatial operations discussed in this paper can be conducted using ArcInfo,
ArcView, and ArcGIS. A set of strategies and rules were proposed and used to build the spatial operational module in the KFD
to make the spatial operations more efficient and topographically correct. |
