Re: [idvusers] Is an update of world country outlines available?

Hi Heiko-

Thanks for pointing this out.  It's been difficult to get good, free maps.

A couple of notes:

- In the latest version of the IDV (2.7u1), the World Coastlines map was updated to a higher resolution map. However, if you have ever changed your default map preferences, then you will not see that map by default. You can get the updated map by:

  - Open the Default Background Map Control window
  - Delete the World Coastlines map by clicking the trash can icon
  - Select the File->Default Maps->Save as Default Map set
  - Exit the IDV.

That will remove the old reference.

  - Restart the IDV
  - Open the Default Background Map control window
  - Select the Edit->Add System Map->World Coastlines map.

Alternatively, if you have not added or changed any of the other default maps, you can use the File->Default Maps->Remove Local Map Defaults and restart the IDV. That will pick up the new map and you can then save that preference.

- I just added a new plugin with a better World Country Outline map.

- Use the Tools->Plugin Manager dialog to add in the Maps->World Maps plugin.
  - Restart the IDV.
- Use the Edit->Add System Map->McIDAS World Country Outlines to get the new map.

If users like this map better, we can set that as the default World Country Outline map. This is from the Unidata McIDAS distribution (as is the new World Coastlines map). If there are any issues with this map, please let us know so we can fix them.

I've been checking some altitude maps over Europe and got a bit confused by using the default IDV (2.7u1) 'world country outlines'. It seems like Iceland (lower left corner) is about 2 degrees more west than the altitude, while Svalbard/Spitsbergen (upper right corner on the attached figure) has only 5% of its actual size.

The same map looks okay with the World Coastlines, which is of lower resolution.

I recognized, too, that the country borders don't reflect the split of serbia and montenegro in 2006.


Does somebody have other country border or higher resolution world coastline files available? Did somebody convert i.e. the recently updated NCL / Ncar graphics database 'Earth..4' to an idv-readable file?

Best regards,

Heiko
