Aye - this really is a valuable resource. Are they somehow affiliated with Slashdot or did they just pick a part of the name ? I should monitor it from time to time just to see if someone already announces what we're still preparing for ;-) > Yes - I've seen just how bad vmap0 roads are in my local area - trying > to match edges between datasets would be a complete nightmare. But in the end someone has to do it - no chance of circumvention unless we find an clever algorithm that does the job for us. >> We are already preparing such a merge but I expect the process to take >> several, not to say numerous months until we're ready to offer the >> first results. > > Is there any way people can help with this? There will be. Currently I'm waiting for someone giving the ok to move my DB to a more powerful machine but I think people can step upon the plate earlier. This page for example: http://www.mapability.com/info/vmap1_download.html mentions the bounding boxes of the respective VMap1 datasets. Before cutting out VMap0 we'll have to know if lat/lon of these boxes is really accurate or not. This could be done either by finding a reliable source which tells us "yes, they _are_ really precise" or by loading data files (shapefiles) into your preferred GIS viewer and determine if the roads and rivers that for example intersect the border between the US and Canada really end at the specified latitude.
