[OSGeo-Discuss] WorldCities database Free and OpenSource
Greetings I'm doing a small tool to calculate distances between cities. I mean, I enter City of origin geographic position and city of destination geographic position and I calculate distances. The thing is, everytime I have to check at GOOGLE Earth a city position and it's getting to be a long a heavy task to do. I realized that, this guys http://www.assemblysys.com/dataservices/db_details.php?db=3 are distributing a database with cities geographic positions but this is PAID :( . What I wanted to know is if there is any tool/software/database free, open source where I can do exacly the same without having to pay for that. And even, maybe add a few cities positions and contribute to the project Thank you Toze ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

Re: [OSGeo-Discuss] WorldCities database Free and OpenSource
A free list is available on http://world-gazetteer.com and you can start out with this. Well, it is not an exhaustive list, but gives the large cities and towns (around 700+). I personally have a list of 4000+ cities and towns for Asia and will share it, if need (this might need some cleaning up though) In addition to the city point list, it might be great if we pool resources to draw in the city (urban agglomeration) boundaries and not administrative boundaries (these are available upto level 3 or 4) - Rajan On Fri, March 5, 2010 11:01 pm, António Rocha wrote: Greetings I'm doing a small tool to calculate distances between cities.

just for USA: US Census TIGER shpfiles, organized by state, *_place has outline polygon, name, state name, some classifiers. also just for USA: USGS' GNIS dataset has lat, long, name, state name, county name, type classifier -- for cities, towns and a whole lot of other stuff.

Olá Antonio, tudo bem? are you looking for a distance matrix tool? QGIS has one, look into the vector menu - analysis tools - distance matrix abraços -- Giovanni -- On Fri, 2010-03-05 at 17:31 +, António Rocha wrote: Greetings I'm doing a small tool to calculate distances between cities.

Do the distance matrix tools work on geographic coordinates? I suspect for GRASS yes, but for QGIS? stefan Markus Neteler wrote: On Fri, Mar 5, 2010 at 7:48 PM, Giovanni Manghi giovanni.man...@gmail.com wrote: are you looking for a distance matrix tool?
