Just finishd Task 6 last night and they look pretty good covering Kathmandu, Hetauda, Bharatpur, Palung and Bhampali. I've since digitised roads in a couple of key tiles based on km distance discrepancies and when I've finished those I'll move on to task 3. The triangular distance table is good but points to a lot of discrepancies in the longer distances which are out of the target zones. I'm happy to digitise the triangular table though if anyone wants to try the URL method to identify areas of difference. I'm using NGAs geonames service to identify differences in place naming - what should we do when there's a difference? e.g "Bhainsie = Bhaise Dovan".

<br clear="none">
The documentation says “The results are network distance, i.e. travel-time, in 10th of seconds.” It’s hard to translate that into distances without the speeds assigned to road segments. If one knows the type of road and what the “common” speed is for that type of road one can make an estimate, but it could still be quite far off. Do you have any guidance on how to get road segment information? If one needs to download the road data itself, then the length of the segments should be there, too.<br clear="none">
