[OSM-talk] Map rendering, which is not aligned to coordinate axes

2009-07-15 Thread Holger Schöner
Hi, I am thinking about the possibility to render maps along rivers, bicycle routes, etc. For this, a collection of thin elongated bounding boxes, which are not aligned with the cardinal directions and/or coordinate system axes, but locally with the waterway or route, would be

Cutting and rotating a normal map would of course not be appropriate, because (beside possible loss of quality) the labels would not be horizontal any more ... If you were working in an SVG frame work you could rotate the whole image then apply a reverse rotation limited to just the labels

hi. a surrounding polygon and osmosis would do the job on a planet file, i think. gary68 gerhard On Wed, 2009-07-15 at 16:06 -0400, si...@mungewell.org wrote: Cutting and rotating a normal map would of course not be appropriate, because (beside possible loss of quality) the labels would

http://wiki.openstreetmap.org/wiki/Linear_maps No solutions there but at least you know now that OJW has thought about this three years ago ;-) Wouldn't a true linear map stretch the way of interest into a straight line and distort the location of adjacent ways/nodes to their nearest

Searching google I found that page too but it appears the correct term is strip map and not linear map which is a mathematical construct. I did not really find anything directly usable but you'll get theorical resources on how to do it. It would be really nice to have something for ways

It would be really nice to have something for ways or, even better, route relations. In terms of rotating the source data for a normal 2D map, you just have to re-calculate the positions on the nodes based on a rotation angle and center of rotation. The ways/relations would automatically follow

Hi All I'm trying to render some maps of my local area, and I followed the notes here: http://www.use-it.be/europe/docs/OSMmanual/ At the end, it says that you can remove features, by removing the rules from osm-map-features-z17.xml file. However, when I took out pubs, for example, they're still
