that is true - but the point I am trying to emphasise is that mapping is a daily activity. Every time you look at the map you can add something - a dustbin, a lamp post, a speed breaker on the road. You may have missed it the first time. And also once you have a few points marked accurately, you can add more points by estimating the distance - even by pacing them out if you are adding a series of light fixtures. And you do not need a GPS to add gates. They are in one of the elite engineering colleges in India - they are sure to have any amount of distance measuring and dimension measuring equipment. -- regards Kenneth Gonsalves Senior Project Officer NRC-FOSS http://nrcfosshelpline.in/web/ _______________________________________________ Talk-in mailing list Talk-in@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-in
