[Aslam Parker]

Hi Ramashia
 
I have high resolution imagery of the Marikana Massacre site and surrounds if you are interested (6.5cm). It was flown with a UAV by Trimble.

Dear All
 
I have a problem that I hope someone on this mailing list could assist with. 
I want to calculate travel time from (each) VILLAGE to the nearest URBAN CENTER along the road network.
The output format could be text or GIS with at least 3 columns: 1. Village, 2. Nearest Urban Centre and 3. Travel Time. 
 
I have 3 data sets: 1. Villages (Point), 2. Urban centers (Point) & 3. Roads (Polyline/line) for the whole country (Namibia). 
 
I would appreciate if someone refers me to tutorials on this. 
I have access to PostGIS, QGIS and GvSIG, ArcInfo, GeoMedia Pro 6.x, MS SQL Server 2008 (Spatial) but am willing to try something else.
 
Rgds,
Uazu
