将 ArcGIS REST 图像拉入 cartopy

问题描述

有什么方法可以将 USGS 网站上的图像导入 cartopy 吗？

https://services.nationalmap.gov/arcgis/rest/services/USGSNAIPImagery/ImageServer

通过窥探，我想

struct ld_sb
{
    System.UIntPtr sb_sd;
    byte Reserved1;
    System.UIntPtr sb_naddr;
    byte Reserved2;
}


public struct LDAP
{
    ld_sb ld_sb;
    string ld_host;
    //...
}```

会抓取图像层。但我得到了以下异常。

ax.add_wms(
    wms='https://services.nationalmap.gov/arcgis/services/USGSNAIPImagery/ImageServer/WMSServer?request=GetCapabilities&service=WMS',layers=[ '0' ],)

我认为服务器不能使用我使用的投影，但我使用的是 web 墨卡托投影，应该没有问题，我认为

    263
    264         # check for service exceptions,and return

    236
    237     return ResponseWrapper(req)

ServiceException: Parameter 'srs' contains unacceptable value.

fig.add_subplot( *pos,projection=ccrs.Mercator.GOOGLE) 是否适合使用？或者我应该使用其他什么东西？

非常感谢！
