Re: [OSM-dev] Mapnik/Postgres: Permissions Issue with contour layer

I've also imported SRTM contour data, using the standard approach documented in the wiki, into a database called 'nickw' which I have full rights over (unlike the 'gis' database).

Hi Nick, Most permissions are at table level, \dp from psql client shows you what permissions currently exist. I've just granted the gis user select on geometry_columns and the contours are now displaying. -- Chris Jones, SUCS Admin http://sucs.org ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

Re: [OSM-dev] finding OSM users by their home locations
On 31 May 2009, at 06:41, Russ Nelson wrote: The OSM webserver will tell you the ten people with home locations closest to your home location. It would be useful to be able to get more than that, for the purpose of inviting people to attend mapping parties so they can become more effective and enthusiastic OSM contributors. If you move your home location to the location of the mapping party, you can get ten people, and if you move it around some more, you can get more than just those ten. Sounds evil... but less evil than your current method of spamming everyone who has edited something nearby. -- Chris Jones, SUCS Admin http://sucs.org ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev

Re: [OSM-dev] Binary OSM; the first pass encoder
Stefan de Konink wrote: Hi All, Because I am getting more and more disappointed with the current state of affairs with respect to the downloading of OSM content some people on the Dutch OSM IRC channel thought of an alternative way of distribution that could potentionally get binary diffs after any possible download in the past. I wrote the first implementation of it in the last couple of hours and tested it on the Dutch dataset. The current gzip compressed data is about 135MB. Extracted it represents 1.4GB of XML. The binary file is completely analogue to the XML, no shortcuts what so ever. The first reduction to binary format containing only data reduced the set to 418MB and allows a bzip2 compression to 78MB. How does gzip do on the binary format? or How does bzip2 do on the xml format. You cant sensibly compare the two if you apply different compression methods. Given how compression works I suspect you'd do better to tweak things like the block size used at compression time than come up with some binary format. -- Chris Jones, SUCS Admin http://sucs.org ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] The wiki defines the database (was: relations)

If the proposal is well prepared and discussed even by a very small number of people knowing what they are talking about, you will - even as an outsider - get a good idea if the feature is a good thing or not. Surely the only voting process that carries any weight in the long run is people actually using a given key/value pair in the database... Why not just provide a list of popular tags (like map_features does now), and a long list of possibilities for things not on the 'popular' list (basicly what the Proposed_features currently do). Any proposed features that see significant real world usage make there way onto the map_features page. -- Chris Jones, SUCS Admin http://sucs.org ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
