[OSGeo-Discuss] WorldCities database Free and OpenSource

2010-03-05 Thread António Rocha
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

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)

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

... and respectively for GRASS:
- how to start it:
  http://grass.osgeo.org/grass64/manuals/html64_user/helptext.html

- Geonames.org import (into lat-long location):
  http://grass.osgeo.org/grass64/manuals/html64_user/v.in.geonames.html

- Distance matrix (use Print output there)
  http://grass.osgeo.org/grass64/manuals/html64_user/v.distance.html
  - Examples, Print distance matrix
  (in lat-long, it calculates them as geodesic distances on a sphere)

Do the distance matrix tools work on geographic coordinates?
I suspect for GRASS yes, but for QGIS?
