Cutting method of tile data in surveying and mapping maps based on ArcGIS

本研究基于ArcGIS的测绘地图瓦片数据的切割方法,提升网络环境下测绘地图的浏览速度。利用ArcGIS软件,通过测绘地图设计、确定测绘地图缓存的比例尺、发布测绘地图任务以及测绘地图切片的过程生成测绘地图的瓦片。在ArcGIS软件的服务器端,设置一个瓦片定时更新的执行任务,定时自动更新测绘地图瓦片。依据瓦片的地面分辨率以及显示比例尺,对测绘地图瓦片数据分级。依据测绘地图瓦片数据分级结果,利用图片切割编码方法对测绘地图进行瓦片数据切割。实验结果表明,本文方法利用ArcGIS软件,有效切割了测绘地图瓦片数据,提升了测绘地图浏览效率与比例尺切换速度。

This paper used the cutting method of tile data in surveying and mapping maps based on ArcGIS to improve the browsing speed of surveying and mapping maps in the network environment.By using ArcGIS software,the tiles of the surveying and mapping map were generated by designing surveying and mapping maps,determining the scale of the surveying and mapping map cache,and issuing surveying and mapping map tasks and slices.On the server side of the ArcGIS software,an execution task of periodic tile update was set,and the tile of the surveying and mapping map was automatically and periodically updated.According to the ground resolution of the tiles and display scale,the tile data of the surveying and mapping map was classified.According to the classification results of the tile data of the surveying and mapping map,the tile data of the surveying and mapping map was cut by using the image cutting and coding method.The experimental results show that the method based on ArcGIS software effectively cuts the tile data of the surveying and mapping map and improves the browsing efficiency of the surveying and mapping map and the switching speed of scales.
