I know this, James. But an edit should change the map for the better. There were trails along Horne Lake, trails with boardwalks and bridges that I walked and mapped by hand. But that work's gone — foom! — replaced with an imported "Horne Lake, v1" with land use polygons that aren't even clipped to the lakeshore. > So have a bit of a look into what CanVec is … You'll find > these artifacts all over. I'd like to suggest that, if an import breaks a country into Minecraft-like square blocks, you're doing it wrong. Many of the import guidelines were broken here, too. Is the CanVec import process described in the wiki moribund? If there had been some discussion here about imports in the 041J locale, I'd have relished the opportunity to help fuse imported and source=survey data. > Large complicated polygons abound in the OSM database.

Import/Guidelines recommends simplifying shapes <http://wiki.openstreetmap.org/wiki/Import/Guidelines#Consider_simplifying>, and MapShaper — the suggested tool — uses a couple of appropriate algorithms. > Everyone's contributions are > appreciated, but occasionally we bump into each other. Yeah, but as a pedestrian, I stood no chance against CanvecImports' steamroller. cheers, Stewart _______________________________________________ Talk-ca mailing list Talk-ca@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ca
