Yes, for sure. I've now had more of a chance to look at the data (thanks, Ottawa, for providing no docs at all ...). I'm pretty sure that the data at http://data.ottawa.ca/dataset/cad-topographic-data is the source of what the Ottawa group were given. In the 31 gigabytes of converted files, about 8-10 of the 177 total layers might be of interest. But: * The files are in some kind of MTM projection, but I don't know the datum. Some munis still love their NAD27, so getting this right is crucial. * These were digitized 2010-2011 at the latest. Since municipalities share data with NRCan, aren't these outlines already available in a recent iteration of CanVec in a much more useful (i.e., anything but DWG) format? My notes on the files, so far: https://gist.github.com/scruss/e7f85da2e7943cb1a1d13772fbe144d3#file-ottawabfomapdata-md (feel free to use/modify/etc) If anyone wants 31 GB of converted DXFs, let me know. It took Teigha several hours on a quad core with SSDs to convert this, so I'm not going to delete it lightly. cheers, Stewart _______________________________________________ Talk-ca mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-ca
