404 error downloading ne_h_coastline.zip

[atmosmattbrewer]

I have recently been getting "HTTPError: HTTP Error 404: Not Found" errors when trying to use Cartopy. Even when I comment out the add features lines I am still getting this issue, so maybe it is caused by some of the other packages. I have clicked on the link and you do get the 404 message, however I am not sure where in my code I am still getting this issue if I comment out the add coastlines.

So the error occurs because it's trying to download this link, which doesn't work:

http://naciscdn.org/naturalearth/h/physical/ne_h_coastline.zip

The question is...why?

Aha! I think it's this line:

display.plot_ppi_map('reflectivity', 0,  resolution = 'h', #The "0" is the lowest PPI scan, increasing this number increases the scanning elevation
             vmin=-10, vmax=64, colorbar_flag = False, fig = fig, ax=ax,alpha = .08, projection = crs)

Notice the use of 'h' for resolution--which corresponds to the bad part of the URL. I'm guess this is left over from some Basemap code? Try changing to '10m' or '110m'.

[atmosmattbrewer]

Changing the 'h' to '10m' fixed the issue, should I open an issue with pyart? Thank you for the help though.

[dopplershift]

It'd probably be nice of them to try to check and issue a more useful error, but that's up to them. Wouldn't hurt to open an issue there to let them know.

I wonder if we should be whitelisting the resolutions here, at least in NaturalEarthFeature class, since we know the currently supported resolutions.

[dopplershift]

So, the question is where to check:

• NaturalEarthFeature
• shapereader.natural_earth
• NEShpDownloader

Thoughts anyone? @pelson?

[jklymak]

Unfortunately something seems to be wrong at NaturalEarth: https://naciscdn.org/naturalearth/110m/physical/ne_110m_coastline.zip gives a 404 as well.

[wckoeppen]

Just coming to write that same thing. It appears that naciscdn.org is offline right now: https://downforeveryoneorjustme.com/naciscdn.org

[pollackscience]

Is there a mirror where one can grab these images?

[jklymak]

I couldn't find one. I've just switched to GSHHS: ax.add_feature(cartopy.feature.GSHHSFeature(edgecolor='k'))

[QuLogic]

You can grab it from their GitHub, though unfortunately due to https://github.com/nvkelso/natural-earth-vector/issues/279 it's not entirely consistent with what's on the site. On Fedora, you can also install one of the natural-earth-map-data packages.

[wckoeppen]

It appears that naciscdn.org has come back up, which should resolve this issue.

[briochemc]

Back down for me...

EDIT:

You can grab it from their GitHub, though unfortunately due to nvkelso/natural-earth-vector#279 it's not entirely consistent with what's on the site. On Fedora, you can also install one of the natural-earth-map-data packages.

Is there a way to download the data from GitHub from within Cartopy?

[greglucas]

Is there an action item for Cartopy here? Better error/failure messages?

Otherwise, there isn't a whole lot we can do when external websites go down.

[QuLogic]

External websites aside, the actual bug here is that we need to be more stringent about what's accepted for scale (because h is not valid for NaturalEarth). That's why this is still open.
