**edit to add, by edge of tile I mean edge of NTS grid, in larger tiles, there will be 16 tiles per file. If scattered, I'm guessing its something in the line generalization routines used by cgpsmapper. If at the edge, it could conceivably be something in my parsing routines. The reason for bringing it up though is that if the duplicate point is not a limitation of the format, then you could save a few bytes here and there by stripping these out of the dataset.Ĭould it have been data from the different layers?Īre these occuring at any particular place on the tiles? (edge vs middle). I'm not sure if this is a 'feature' of the IMG format, can a polyline have only one line or is there a minimum of two? Anyway, it was a simple fix to ignore duplicate points.

Typically it is a single road line piece but the end point is duplicated. Turns out that a fair number of street poly lines in the map data have duplicate points in them. I've totally re-written my IMG map renderer and it now looks more like google street maps with the anti-aliased fat curved edges for the roads and such but when viewing your maps I was noticing a weird rendering glitch on a lot of the cul-de-sac ends.
