地理实体数据建设关键技术研究及应用探索
Research on the Key Technologies and Application Exploration of Geo-entity Data Construction
摘要
Abstract
Through the construction of geo-entity in new fundamental surveying and mapping project,we analyzed the organization structure of entity data and the fusion mode of multi-source heterogeneous spatial data,designed an entity extension coding rule,and developed a coding tool based on this system,which could solve the applying and sharing problems of multi-source data caused by spatial structure difference and com-plex attribute information.The coding system standardizes the entity code structure,and based on the coding tool,the entity code can be fast cod-ed.Using this method,we constructed the geo-entity database in the pilot area,and built the display system and application scenario,which could provide an effective solution for the construction and application of geo-entity.关键词
