摘要
GIS的主要功能就是实现地理特征的快速标注,要想能够有效提高地图理解能力,可以通过地图标注实现,一直以来,地图标注都是GIS和制图中的研究热点和重点内容。在地理信息指数不断增长的过程中,大量的数据快速符号化是现代地图信息传输过程中需要解决的问题。基于此,就提出了GIS地图符号快速标注算法,从而能够使全局环境转变为分组标注序列,实现标注过程的分解。通过实验证明,比起常规的方法,此种标注算法能够有效提高地图标注过程中的速度,并且还为海量数据的快速符号化的研究奠定了基础。
The main function of GIS is to realize the rapid labeling of geographic features.To be able to improve the ability of map comprehension effectively,it can be realized by map annotation.All the map labels are the research hotspots and key contents in GIS and cartography.In the process of increasing the geographic information index,a large number of fast symbolization of data is a problem that needs to be solved in the process of modern map information transmission.Based on this,this paper proposes a GIS tag symbol fast labeling algorithm,which can make the global environment into a grouping tag sequence,to achieve the decomposition of the decomposition process.Experiments show that this kind of annotation algorithm can effectively improve the speed of map marking process and provide the basis for the rapid symbolization of massive data compared with the conventional method.
