POI-based land class subdivision method and device, storage medium and terminal equipment

Abstract

The invention discloses a POI-based land class subdivision method and device, a storage medium and terminal equipment, and the method comprises the steps: carrying out the classification processing of POI data and surface data, and obtaining a classification result; based on the classification result, the category and the number of POIs contained in each land block in the original land utilization classification data are judged; if the land parcel only contains one type of POI, endowing the type of the POI to the land parcel; if the land parcel contains multiple types of POIs, performing surface data hierarchical segmentation on the land parcel, endowing the segmented land parcels with the types of the surface data and the POIs according to a preset priority, and classifying the land parcels without the types after segmentation as the types of the land parcels closest to the land parcels to which the land parcels belong; and if the land parcel does not contain the POI or the land parcel contains the POI but has no category, performing buffer analysis on the land parcel, then judging the category and the number of the POI contained in the land parcel again, and classifying the land parcel based on the category and the number of the POI contained in the land parcel. According to the invention, subdivision of land utilization classification data is realized, and a large amount of manpower and time consumed by manual investigation are saved. 本发明公开了一种基于POI的地类细分方法、装置、存储介质及终端设备，方法包括步骤：对POI数据和面数据进行分类处理，得到分类结果；基于分类结果判断原土地利用分类数据中各地块包含POI的类别和数量；若地块仅包含一种类别POI，则将POI所属类别赋予所述地块；若地块包含多种类别POI，则对地块进行面数据分层分割，再将面数据和POI的类别按预定优先级赋予分割后的地块，对分割后没有类别的地块，将其归为与其最近距离的地块所属的类别；若地块不含POI或所述地块包含POI但无类别，则对所述地块进行缓冲分析后再次判断所述地块包含POI的类别和数量，基于所述地块包含POI的类别和数量对所述地块进行分类。本发明实现了土地利用分类数据的细分，节约人工调查所消耗的大量人力与时间。
