For general help on OSM Overlays, see the documentation: DE / EN.

OpenLayers: (EN / DE) "is an open-source implementation of a “Slippy Map” interface. It is a JavaScript library released under the BSD license. It is one of several libraries you can use to deploy your own slippy map on a website." – Examples

online form to add points to a map¶

interactively¶

With this online tool you can add new points and export the image link in several formats.

find NPP listed in the nuclear-heritage.net-wiki
search for location on openstreetmap
choose ‘add new point’ and click on the map

static using Openlayers¶

Download the attached files map.html, npp-coords.txt, nuclear_power_plant.png to one folder and open the map in your browser. It will show the map with some of nuclear power plants around the baltic sea.

POI are defined either statically with a textfile in this format or can be loaded from a SQL database. The map is included with some little javascript.

    map = new OpenLayers.Map("mapdiv");

URL¶

If you have the coordinates of an NPP already you can edit the image url directly. Add the following line to the URL.

&mlatX=65.93092863127&mlonX=24.3017578125

(‘X’ represents the number, which obviously should be the last number used + 1)

The syntax for the whole URL follows this scheme

http://ojw.dev.openstreetmap.org/StaticMap/?lat=60.525022660959&lon=21.26953125&z=5&w=964&h=716&layer=hiking&mode=Export&zoom_to_clicks=off&show=1&mlat0=65.93092863127&mlon0=24.3017578125&mlat1=64.418435776563&mlon1=24.3017578125&mlat2=61.48353941457&mlon2=21.4013671875

Layered maps for Mediawiki¶

use OSM with mediawiki (slippymap is outdated)

Extensions:Maps + SemanticMediawiki¶

Example

{{
#display_map: 55.7557860, 37.6176330
| service=openlayers
| layers=osm-mapnik, osm-cyclemap, osmarender
}}

Installation¶

Requires Mediawiki 1.18. NH uses 1.19.

Once you have downloaded the code, place the Maps directory within your MediaWiki ‘extensions’ directory. Then add the following code to your LocalSettings.php file:

# Maps
require_once( "$IP/extensions/Maps/Maps.php" );

Semantic Maps.¶

To further enhance the map, Semantic Mediawiki is needed.

Map data then can be exported in several formats, like KML (WP).
For further use they can be translated to GeoJSON with togeojson: mapbox.github.io/togeojson

The useful list used by grazwiki.at is long. They enable to add questions to your wiki pages:

{{
#ask:
[[Koordinaten::+]]
[[Kategorie:aktuell]]
| ?Koordinaten
| format=openlayers|width=100%|height=300|icon=nachbar.png
}}

installation¶

usage¶

basic example

{{#display_map:new york city
| layers=osm-mapnik, osm-cyclemap,  bing-hybrid
| service=openlayers
}}

standalone map software¶

combine dspace compatibility with modestmaps (chron0), leafletjs (elf) + neokarto
cors, leafletjs

Wiki tasks¶

in the Wiki add the template to all NPP pages, like for Olkiluoto
currently the NPP category is mixed with NukeNews and should be separated.
