What makes you think the Yahoo! imagery and/or the contour lines shown on the Cycle Map(these contours are from SRTM data, not OSM) are more up to date or more accurate/precise than the existing water body drawn in OSM? Also, posting a map url or link to the object of the reservoir in question could be helpful. -- Gregory [email protected] http://www.livingwithdragons.com
