基于Python的离线Google地图操作实现

Implementation of Offline Google Map Operation Using Python

在线Google地图以及开放的基础地理数据为GIS系统开发提供了便利。运用Python语言,针对离线Google地图瓦片数据文件,实现了地图瓦片拼接、卫星和平面地图切换、平移、缩放、鼠标响应、轨迹显示等地图操作,对于提高测绘质量及其实时显示与交互技术具有重要意义。

Online Google map and open map data are of benefit to GIS system development.In this paper,the offline Google map tile data are processed using Python programming language.Some map operations are implemented including map tile stitching,2D/3D map switching,map moving,map zooming,track drawing and mouse response.It is very important to mapping,real time display and human-computer interaction.
