摘要
地理信息系统(GIS)采用文字标注方式提高地图可读性,以实现对地理信息的显示和提取。而如何使地图文本标注更易于理解是GIS的重要问题。针对复杂多变的中文文本信息,为找到最佳的地图标注位置,弥补现有技术的不足,提供一种基于GIS平台、电网资源以及气象平台的空间GIS文本动态标注方法,该方法能够为空间关系抽取和场景构建提供准备数据,有效地描述GIS中的空间关系,并实现文本类信息动态标注,优化GIS平台的展示效果。
Geographic information system （GIS） uses the text annotation way to improve the readability of the map,to achieve the display and extraction of geographical information.How to use label text to make the map easier to understand is an important problem of GIS.In view of the complicated Chinese text information,in order to find the best location for map label, and to compensate for the inadequacy of existing technology, a spatial GIS dynamic text annotation method is provided based on GIS platform,the grid resources and meteorological platform.The method can prepare data for spatial relation extraction and provide scene building,effectively describe the spatial relationships in GIS,realize the dynamic annotation of the text information,and optimize the display effect of GIS platform.
