Leaflet and vector layers
by Josh Doe 29 Feb '12

29 Feb '12

I'm very interested in using the Maps extension, but I'd like to overlay a vector layer, e.g. to show the extents of a park, city, etc. Has anyone considered adding such support to the extension? I'm also interested in a lightweight alternative to OpenLayers, namely Leaflet [0]. Also check out the new Leaflet Vector Layers [1]. I suppose the biggest question is where should the vector data come from. For simple polygons with a few dozen points it could be passed in directly. With Vector Layers you can pull data from GeoCommons [2] and other databases easily. -Josh [0]: http://leaflet.cloudmade.com/ [1]: http://geojason.info/leaflet-vector-layers/ [2]: http://geocommons.com/

Adding links based on coordinate (point in polygon)
by Josh Doe 24 Feb '12

24 Feb '12

I'd like to add text and/or links based on the geographic location of an article. For example I'd like to link to the local political, election, and school districts that the subject of an article belongs to, based on a GIS file (specifically Shapefile). Another possibility would be to query OpenStreetMap data (via local DB, XAPI, Overpass, Nominatim, etc.) for other information like place names. Thanks, -Josh

Maps on other MediaWiki sites
by Josh Doe 24 Feb '12

24 Feb '12

I'm helping a local wiki get off the ground, Fairfaxpedia [0], that aims to by a hyperlocal-Wikipedia for Fairfax County, Virginia, USA [1], and I'd definitely like to integrate maps. I'm having trouble sorting through the different technologies, understanding what is most current, relevant, how to port to another MediaWiki installation, etc. Coord templates, WikiMiniAtlas, OSM Gadget, and Semantic Maps are a few of the things I've come across. Is anyone aware of other MediaWiki sites that have successfully implemented maps using some of these features? Any pointers? Links to docs that I might have missed would also be welcomed. Thanks, -Josh [0]: http://www.fairfaxpedia.com [1]: http://en.wikipedia.org/wiki/Fairfax_County,_Virginia

Re: [Maps-l] Maps-l Digest, Vol 28, Issue 4

Dear all, Thanks for your large efforts to allow GIS maps **display** into wikipedia's articles. There is also an on going efforts to allow GIS maps **edition & storage** for wikipedia's usage, and so for encyclopedic maps. GIS EDITING advancement : Sharemap.org took the initiative to create a GoogleMap-like for Wikipedia. A system (Sharemap.org) where wiki mapmakers can create, edit, store their encyclopedic maps. This in a centralized GIS way with standardized icons, designed for Wikipedia. Maps such the "Battle of Watterloo", "Birth rate in the US", "Japanese topography", etc will be possible. Translate a map will only involve the translation of the labels layers making translations easier (= more languages) compare to commons. The GIS maps will be downloadable in SVG/JPEG format too. This stage is already largely working. GIS EDITING need SUPPORT : for inclusion in wikipedia Secondly, the project wish to allow inclusion of its maps within wikipedia articles. Your knowledge will be appreciate. Languages used being : 1. *ActionScript 3* with Flex framework for visual editor 2. *Java* for site management and map and content repository 3. *JavaScript* for SVG rendering code Jakub, the programmer, may tell you more if interested. (I'm a map maker). GIS EDITING need SUPPORT : to connect to the WM foundation : Sharemap.org is also looking for contacts, programmers, scholarships to solidify or actively support this project and associate it with the wikimedia foundation. The project is opensource (CC-BY-SA 3.0), willfully a wikipedia friendly license. Please, who is interested for more information ? Who may I contact for further collaboration with Wikipedia/Media ? Best wishes ! -- Hugo Lopez

Extraordinary hardware-maintenance 16 and 17 February
by DaB. 20 Feb '12

20 Feb '12

Hello all, Nosy and I will visit the datacenter on short-term-base tomorrow and the day after, to install the remaining hardware and for some maintenance [1]; this will cause downtimes and rebootings between Thursday: 15-24 o'clock UTC Friday: 09-22 o'clock UTC. For normal the reboots will be announced on the shell 5 minutes before they happen, but accidents may happen; so please do not open files and leave your computer. If you plan to do something that takes some time (like a long download), please to it at night-times. If possible, use SGE [2] (you should always do that). We will try to be at IRC (at least from time to time), but we can not guarantee that. Sincerely, DaB.

Tricky problem rendering tiles (coastline incomplete)
by Kay Drangmeister 02 Feb '12

02 Feb '12

Hi all. I have a rendering problem that I am desparately trying to hunt down. Please have a look at low zoom tiles (I use the (modified for b/w) original osm stylesheet, the newest one, for mapnik 2.0). Of course I use mapnik2 as well. Z0: http://drangmeister.net/osm/wz0.png Z1: http://drangmeister.net/osm/wz1.png Z2: http://drangmeister.net/osm/wz2.png Look at parts of Australia missing. I confirmed it has nothing to do with recent remapping efforts in that area :-) Zooming to Fiji at Z4: http://drangmeister.net/osm/wz4.png you see that the islands are missing. Zooming further in to Z10 they appear: http://drangmeister.net/osm/wz10.png So it looks as if there's a vertical strip worth about 1 tile wide around the 0° / 360° longitude that is not rendered, independent of the zoom. I.e. at Z0 halve australia is missing, at Z4 only Fiji and NZ is missing, at Z10 only maybe an island of Fiji is missing. Here is the relevant part of the stylesheet for rendering: <Style name="world"> <Rule> <MaxScaleDenominator>250000000000</MaxScaleDenominator> <MinScaleDenominator>750000</MinScaleDenominator> <PolygonSymbolizer fill="#eeeeee"/> </Rule> </Style> <Layer name="world" status="on" srs="+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs +over"> <StyleName>world</StyleName> <Datasource> <Parameter name="type">shape</Parameter> <Parameter name="file">/home/osm/data/world_boundaries//shoreline_300</Parameter> </Datasource> </Layer> If I rename shoreline_300.shp away then I cannot render anything due to errors, so it's the correct file being used. It also appears to be no problem of the database, because as with Fiji, the data is there, just not being rendered in Z4. Is there a "render bounding box" somewhere I don't know, maybe in tirex? There's nothing suspicious in the /etc/tirex config files. Kind regards, Kay
