- W2371895027 abstract "Points cluster is a set of points which generally have its specific organizational structure. Gully is a self-contained class and important spatial entity, so the gully feature point cluster which expresses and describes gully's morphology, structure and the key attributes have tight organizational structure, close spatial relationship and complete description of the properties. Establishing the spatial structure model of gully feature point cluster and applying the model to the gully features' spatial analysis and application have important scientific significance. There are some important completed works. Firstly, based on analyzing the elements, spatial and structural characters of gully feature point cluster, the existing stored method of spatial data point information was analyzed. By using object-oriented modeling ideas, the gully feature point cluster data model was designed for describing gully's topology and other spatial information based on hierarchical model and unstructured file storage. The gully feature point cluster data model was achieved by C#. And then, based on the point cluster file, the prototype system was researched and designed. Through using visual C# and ArcEngine, visualization(tree structure), spatial analysis(correlation structure), property characteristics analysis(statistics, and hydro-geomorphological analysis) and other basic functions of gully feature point cluster were realized initially. Finally, as a case study, the feature points retrospective sought, the processing time was comparatively analyzed and the time-consuming and point number relationship figure was drawn. The analysis verified the documents based on feature points cluster analysis with a more gully high processing efficiency. In this study, a new idea using point cluster model for gully analysis of expression was practiced. Established the point cluster prototype system orienting valley structure, morphology and properties analysis functions has some practical application value." @default.
