Hi Bjorn!

Thanks a lot for this! It's very helpful to my project for my client. :)

I have a problem though, can you divide Sudan to "Sudan" and "South Sudan"? I need South Sudan in the list of countries.

http://en.wikipedia.org/wiki/Southern_Sudan

Can you also add Alderney or at least combine it with Guernsey to form Guernsey and Alderney?

http://en.wikipedia.org/wiki/Alderney

I'm using the simple one by the way. :)

Thank you very much!

Very helpful - thanks a lot!

This is great work indeed, Bjørn.

Could you explain how you went about the simplification to get it from 3.3 MB to 226 KB?

How up-to-date are the political boundaries? Circa 2008, or earlier?

Thanks,

Hi all,
Sorry if I'm wrong here, but I've noticed that some of the population estimates seem to be a factor of 10 out.... This is not necessarily an exhaustive list but countries I've identified are Italy, Colombia, Saudi Arabia, Niger, Mali, Ghana and Senegal. You can correct the populations in R using correctid <- c(86,38,177,126,113,69,183) and correctpop <- c(58093000,45600000,24573000,13957000,13518000,22113000,11658000). I've taken the figures from http://en.wikipedia.org/wiki/List_of_countries_by_population_in_2005

Hello again,

A few more items to report:

Hello again,

A few more items to report:

1) There is now a 'Hello World' GeoDjango application using your data available at:

http://code.google.com/p/geodjango-basic-apps

2) I've yet to look closely at the reprojection issue, but when I do I'm also going to look more closely at the invalid antarctica polygon issue described here:

http://www.nabble.com/modifying-XMLGettingStarted-to-output-in-mercator-projection--tt17664268.html#a17664268

Of course if anyone else digs into the issue please post here!

Cheers, Dane

There is a small (but funny) bug in the dataset.

The "United Arab Emirates" are mistyped as "Untied Arab Emirates", at least in version 0.2 (which is what i'm using right now).

Hi Dane,

Good to see that this dataset is used in an open source project.

I've not given thought to reprojection issues width this dataset. I think you're right about multipolygons, - being on both side of the dateline might cause some problems for some projections. Maybe splitting multipolygons that cross the dateline will solve your problem?

Please notify me if you're able to find a solution.

Bjorn,

Thanks for this great contribution. ...

Bjorn,

Thanks for this great contribution. Using your data there's now a Mapnik tutorial here that creates a simple thematic map of world population: http://trac.mapnik.org/wiki/XMLGettingStarted#WorldPopulationXML

I'm curious if you have given thought to reprojection issues with this dataset? I'd like to use it for tutorials involving reprojection but it appears that the use of multipolygons can cause havoc near the dateline. This does not happen with the world_borders.shp from mapping hacks.

For an example of this try:

ogr2ogr -t_srs http://spatialreference.org/ref/user/north-pacific-albers-conic-equal-area/ TM_WORLD_BORDERS_SIMPL_pacific_albers.shp TM_WORLD_BORDERS_SIMPL-0.2.shp

Whatever the nuances of copyright/database law in your area, can I assume you intend this dataset resulting from your modifications to be in (or essentially) also in the public domain? The Readme file is a bit unclear on this topic.

The shapefiles should be ok, but they are zipped on a windows computer using 7-Zip (www.7-zip.org). I'm not familiar with the unzip Linux command.

Congratulations for your blog!

I can not open your shape file. I use Linux and this is the out screen

$ unzip TM_WORLD_BORDERS-0.1.zip
Archive: TM_WORLD_BORDERS-0.1.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.

Is your shape ok?

Fantastic work! I've been looking for a world border dataset like this for a LONG time.
