My GPS (garmin oregon 550) comes so close to supporting this natively with its built in compass, but falls short. It has a mode which lets you point at an object, then estimate a distance, then it projects a waypoint. All it needs is the ability to point at the same object from two different locations, then triangulate.

Main lines are generally tagged as power=line whereas suburban lines are tagged as power=minor_line. Main lines generally use towers and cross large areas of land, where minor lines often cross through areas already full of street data. Ive been tagging all nodes as power=tower where its evident from nearmap that there is a large metal tower, however rendered tiles only show the power=tower nodes, not the power=pylon nodes. I figured I was best off doing the line tracing then if renderers support it at a later date, its not too difficult to change the node to power=pylon. When I create the ways, I go from pylon to pylon, with no in-between nodes, so can depend on every node that isnt labelled as power=tower being a pylon. I havent seen many power lines drawn for Australia, but since they are relatively easy to trace on nearmap and can be useful when shown on maps at high zoom levels, I figured Id trace them in. Ive also traced a large number of powerlines from the Shepparton Nearmap, using the same method described above.

For those interested, here's the current draft released this evening: http://map-data.bigtincan.com/data/OSM_Local_Chapters_Draft_v0_3.pdf My concerns about this still haven't been addressed and it doesn't look like it will happen so I won't be at this stage pursuing any form of a local chapter in Australia, there is still a need for a local entity so I'll focus my efforts on getting that finalised once I tweak things based on some suggestions Brendon made a while back. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
[talk-au] answers to difficult questions
John Smith wrote "Laser range finder wouldn't go astray either :)" I think that this would make an interesting mapping party How many ways can we find to map this wind farm without having hi-res imagery or having to break down their gates. 1) compass,gps, high school maths. 2) theodalite, professional gps and a real live surveyor. 3) photographic techniques 4) laser rangefinder + gps 5) audio tracking ??? and what accuracy could we expect with each method if we basically stay to the public roads. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
