All the best, not sure how you do it with the other GIS software you mentioned, do share if you get it.<br>Regards<br>Sandy<br></div></div><hr><span style="font-family:Tahoma,sans-serif;font-size:10pt;font-weight:bold">From: </span><span style="font-family:Tahoma,sans-serif;font-size:10pt">Ramashia, Kenneth</span><br>

<p class="MsoNormal">Dear All<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I have a problem that I hope someone on this mailing list could assist with.
<u></u><u></u></p>
<p class="MsoNormal">I want to calculate travel time from (each) VILLAGE to the nearest URBAN CENTER along the road network<b>.</b><u></u><u></u></p>
<p class="MsoNormal">The output format could be text or GIS with at least 3 columns: 1. Village, 2. Nearest Urban Centre and 3. Travel Time.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I have 3 data sets: 1. Villages (Point), 2. Urban centers (Point) & 3. Roads (Polyline/line) for the whole country (Namibia).
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I would appreciate if someone refers me to tutorials on this. <u></u><u></u></p>
<p class="MsoNormal">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.<u></u><u></u></p>
