Thanks dieterdresit for your comments. I am studying the way OSM works right now. How easy is it to extend the tagging system?

Thanks @escada! Its clear now.

@SK53 … Thats a good point you make. Middle men are useful only as long as they do not control the prices and use the workers as slaves of some sort. Such things tend to happen here. But you are correct about me actually doing some field work to discover the ground reality…then the tagging scheme which will be most effective will reveal itself. Thank you for that tip.

Hi @escada , how is Umap different from the regular maps? Sorry for asking such basic questions. I am only a couple of days old to open source mapping.
