Re: [OSM-dev] Best way to validate user input
Hi, We have other nav data - contributing it to OSM...hrm. http://x-plane.org/home/robinp/FileDef.htm My immediate concern would be: the data is all GPL last I checked. Now..I have no idea what it MEANS when you have GPL on a non-code work (which I think is the main reason why GPL != CC-BY-SA) but now I am rapidly spiraling into osm-legal territory. Bottom line is you'd have to work out licensing. The data is a combination of imports and processing by Robin Peel (who runs the data) and a bunch of user contributions). Now I can talk a little bit more about suitability... - Some of the data you might get (e.g. airways) are very large in physical size (but small in node count). While I point to a sectional map as a mapping use of OSM, the truth is that X-Plane's OSM needs are very much tied to the ground map because that's what we visualize. - Most of the data represents individual features in the real world fairly well, e.g. a VOR transmitter is represented by the lat/lon location of the antenna, more or less. But airports are a little bit tricky - we have always supported (1) the overlapping of taxiway polygons and (2) no metadata on those polygons. So you could use user contributed apt.dat layouts to draw a potentially very accurate image of the ground footprint of the airport, but you would not be able to apply meta data like that area of pavement is taxiway B. In fact, that meta data problem is very difficult because often the taxiways are just names and lines painted on a huge monolithic paved area. The newest apt.dat 850 format solves this at a very low level, by giving authors control over signs, lines, and pavement, rather than providing premade primitives. We did this because there is just so much real-world variability to markings. (We still use high level primitives for runways, that is, one runway makes all its lights, signs, pavement, and lines.) cheers ben OJ W wrote: How about this for a link showing some of the features displayed on typical charts? http://www.avn.faa.gov/index.asp?xml=naco/online/aero_guide Does X-plane/flightgear have any radionavigation data they could add to the chart?

Re: [OSM-dev] Best way to validate user input
Thanks everyone for the pointers - I'll have a look at these existing facilities...for the cycle, we dont' know yet, could be weeks, months, a year? Long enough that the author of the erroneous data may have moved on to other projects. :-( cheers Ben Iván Sánchez Ortega wrote: El Viernes, 31 de Octubre de 2008, Ben Supnik escribió: Now I am looking at the problem of error detection.

Long enough that the author of the erroneous data may have moved on to other projects. :-( You should try to keep the cycle as short as one week.

For example, I saw that one site culls the whole-earth export for unofficial tags...does JOSM know the approved schema and tell users when they haven't done what they should? Would adding this capability be appropriate? There is no approved schema in OpenStreetMap.
