谷歌地图卫星影像下载，合并，导出geotiff工具

Python 100.00%

google_map_satellite_download's Introduction

google_map_satellite_download

0.0 开始

工作中需要使用无偏移的谷歌影像，发现市面上的影像下载工具如bigemap需要付费，或是有水印，上家公司有影像下载工具，就想自己写一个。不是做GIS，对OpenCV、GDAL、Python也没有深入了解，见谅。

简单实现了下面三个功能：

支持下载谷歌地图卫星影像散列瓦片
支持下载谷歌地图卫星散列瓦片合并为一张png
支持合并后图片转换为geotiff

0.1 注意

需要能访问google服务器，请在代码中配置你的proxy

0.2 下载tiff,使用 download_tiff.py

只需使用download_tiff，便可下载并生成tiff 生成geotiff文件，需要GDAL，已经编译好的GDAL windows版本

0.3 下载瓦片,使用 download_tile.py

下载散列瓦片，只需使用download_title.py, 便可在nginx + leaflet中使用。

    point_lt = Point(116.286476, 40.069985)

    # 开始级别 
    level_start = 16
    # 结束级别
    level_end = 17

    for i in range(level_start,level_end+1):
        core(point_lt,point_rb,path,i)
