Python 3.x gis中边界盒的解析

Python 3.x gis中边界盒的解析,python-3.x,geolocation,gis,raster,rio-tiler,Python 3.x,Geolocation,Gis,Raster,Rio Tiler,我试图理解地球静止分析 test_img_msk = "http://oin-hotosm.s3.amazonaws.com/5a95f32c2553e6000ce5ad2e/0/10edab38-1bdd-4c06-b83d-6e10ac532b7d.tif" test_img_msk_rast = rasterio.open(test_img_msk) print('test imag mask bounds ', test_img_msk_rast.bounds)

我试图理解地球静止分析

test_img_msk = "http://oin-hotosm.s3.amazonaws.com/5a95f32c2553e6000ce5ad2e/0/10edab38-1bdd-4c06-b83d-6e10ac532b7d.tif"

test_img_msk_rast = rasterio.open(test_img_msk)
print('test imag mask bounds ', test_img_msk_rast.bounds)

from rio_tiler.io import COGReader
with COGReader(test_img_msk) as cog:
    print(cog.info())
上面的代码输出如下所示

我的问题是输出2中边界框
left=683715.326640001和left=-61.287001876638215
之间的关系是什么。
如何解释这一点?请帮助

您的数据集
test\u img\u msk
有一个投影坐标系,具体使用米的坐标单位

第二个边界框似乎位于不同的坐标系中,可能是地理坐标系,其中坐标单位为十进制度数

最后,您的
边界是相同的位置,只是在不同的坐标系中

有关投影坐标系与地理坐标系的详细信息

编辑


查看显示,使用
transform\u bounds

将边界框坐标从本机投影转换为GCS WGS84,感谢您的输入。如何检查第二个边界框所指的坐标系。@venkysmarty请查看我的编辑谢谢,现在提供的信息使我能够理解输出
