Proposal talk:Contour

Wrong method

I don't think these contours should be in the OSM data like the way we store ways. Sure, height maps are very nice to have in OSM, but it'd need it separate data structure as it's data type is completely different. --Eimai 12:20, 1 November 2008 (UTC)

There are methods of downloading and converting contour data to OSM for the purpose of generating maps, there is absolutely no need to store this data in OSM. Tools like OSM Composer have integrated downloading of such data from various sources, to use this type of data you need a lot of disc space. To implement this in OSM means downloading street data for a simple 2D map is almost impossible. --Skippern 21:04, 4 November 2008 (UTC)

The common SRTM data set is missing quite a lot of populated areas, but hopefully that will change sometime. It's also easier to enter elevations for some individual nodes, where known, with ele=* than to draw full contour lines. Alv 21:39, 4 November 2008 (UTC)

This is definitely not what OSM is meant for, as this kind of data can have no topological relationship to any other entity in the database; perhaps someone can create an OpenContourMap if they wish to crowd source this data. I'm marking this proposal as abandoned. -- Joshdoe 15:41, 22 August 2011 (BST)
