摘要
针对各类兴趣点扒取时区域过大而造成兴趣点数据丢失的问题,本研究通过FME对研究区域进行格网划分,采用Geosharp软件按照格网经纬度从高德地图中分区获取格网小区兴趣点,并基于ArcGIS构建了分区导出模型和量化处理。研究结果表明:格网坐标提取模型和分区导出模型能够较好地自动处理导出各类兴趣点数据,提高数据扒取和处理效率,比原有裁剪导出更节约时间,能够为交通规划提供前期的基础数据支撑。
In order to solve the data loss caused by the large amount of interest point data in the study area.In this study,the research area was divided into grids using the FME.The point of interest of grid cells was obtained from the grid map which was got from the Amap according to the grid longitude and latitude using the Geosharp software.Based on the ArcGIS,the partition export model was constructed,and the quantitative processing was carried out.The results show that the point of interest data can be automatically processed and exported using the grid coordinate extraction model and the zoning model.The efficiency of data picking and processing is improved,the handling time is saved effectively compared with the original cutting export.This study can provide early basic data to support traffic planning.
