GEO data for cities

[Самойлов Константин]

Hi Bjørn!

Your API at http://thematicmapping.org is really great!
Could you tell - can I display Pie chart map with info about cities
not just countries. I need higher detalization.
Thanks in advance!

Hi Kostya,

Yes this should be no problem. You need the latitude/longitude
position of each city. The data table should be like this:

1. [Name, Required]
2. [Latitude, Required]
3. [Longitude, Required]
4. [Border, Optional] Empty column in your case
5. [Value, Required] This is the statistical value representing the
pie size (e.g. population)
6.-X. [Value] One value column for each pie value

Se also the pie chart example:

Please report any problems!

Bjørn

Hi Bjørn!

Thank you very much!

And one more question - I have only names of cities by now. Are there any means to transform City Name -> Latitude, Langitude?

Thanks!

Kostya.

You could try the Google Maps API geocoding service:

Bjørn,
I tried to follow the directions you've given, in order to create a
KML layer. However, when I try and produce the KML with:

map.draw(data,options);

I get stuff that does not resemble KML at all! You can have a look at
what I'm doing here:

www.cimearth.org/pieGraphTry.html

Currently the web site draws a table based on my data, so that you can
see what data I'm feeding to the API. Just un-comment lines 146-147
to see what KML the engine produces.

Do you have any idea what's wrong with this?

Thanks!
