Welcome fellow mappers

My name is Kai, born ca. 1982 in Bremen, Germany ;-)

I started mapping in OSM to edit features for my other hobby Genealogy - and used the maps long before while Geocaching.

Shout outs to the German Telegram Group where many nice people have answered a lot of my newbie questions :-)

If you're dissatisfied with any of my edits, feel free to edit my talk page.


If you'd like to contact me, either use the OSM message function or contact me on the only social media channel that I monitor, twitter/@kmpoppe - or on Telegram/@kmpoppe


I support the idea Open-Source and would encourage everyone to do so as well. Things I've worked/I'm working on include:

  • 2FactorAuth: A great collection of sites, using 2-Factor-Authentication for enhanced security - (on GitHub)
  • MapSwipe: This mobile app easily allows users to support the Humanitarian OSM Team by presenting you with easy tasks (e.g. identifying building and roads). The data flows into the Tasking Manager. This supports Humanitarian organizations to get better maps for faster response in a crisis. - (on GitHub)

WMS Tile Server for OS OpenData USRN (July 2020)

How to set up a server yourself

  1. Download the latest stable release of the GeoServer from (Platform Independent Binary) and unzip the downloaded file to a new directory.
  2. Check the Installation instructions at for the prerequisites (especially a working Java JDK). Depending on your operating system continue with the OS-specific instructions on how to setup the GeoServer and start it so that you can login to the administration interface.
  3. Download the GeoPackage from and unzip it to the data_dir or a subdirectory of your choosing.
  4. Login to the administration interface of GeoServer with the username admin and the password geoserver. Obviously this password should be changed first thing – scroll down to "Security" in the left navigation panel and click on "Users, Group, Roles". Go to "Users/Groups", click the user "admin" and then change the password to something unique you remember.
  5. Next, go to "Stores" in the "Data" section and click "Add new store". Under "Vector Data Sources" choose "GeoPackage".
  6. You need to supply a workspace (this should default to "cite"), a Data Source Name (choose something unique) and the Database under "Connection Properties" – click "Browse..." to find the .gpkg file that you extracted in the data_dir. Scroll down to "Save".
  7. After adding the Data Source, you’ll automatically be redirected to "Add New Layer" – the layers are what will be published via the WMS-service of GeoServer. The proposed Layer Name is "openUSRN", which is read from the GeoPackage automatically. Click "Publish".
  8. Almost everything is set, apart from the "Bounding Boxes" (scroll down to that heading). Under Native Bounding Box, click "Compute from data". It'll take a few seconds and then add the correct values. Under "Lat/Lon Bounding Box" click "Compute from native bounds".
  9. There's no need to change anything else and you can click "Save". If you want to add the same style that I used on my server (2 px solid line in different colour and a text description), click "Styles" under "Data" and add a new style, give it a name and paste this Style content:
<StyledLayerDescriptor version="1.0.0" 
	xsi:schemaLocation=" StyledLayerDescriptor.xsd" 
			<Title>OS USRN Line with id</Title>
			<Abstract>A sample style that draws a line</Abstract>
					<Title>OS USRN Line with id</Title>
					<Abstract>A solid blue line with a 2 pixel width</Abstract>
							<CssParameter name="stroke">#0000FF</CssParameter>
							<CssParameter name="stroke-width">2</CssParameter>
							<CssParameter name="font-family">Arial</CssParameter>
							<CssParameter name="font-size">12</CssParameter>
							<CssParameter name="font-style">normal</CssParameter>
							<CssParameter name="font-weight">bold</CssParameter>
							<CssParameter name="fill">#FFFFFF</CssParameter>
  1. Go to Layers, click on the Title of the Layer you added and click "Publishing", scroll down to "WMS Settings"/"Layer Settings" and set the "Default Style" to the name of the Style you just added.
  2. Using the above mentioned documentation, you can now add your server as a WMS server in JOSM. If you're unsure if the server delivers the correct layers, use the "GetCapabilites" URL:

http://<ServerName>:8080/geoserver/wms?service=wms&version=1.1.1&request=GetCapabilities and click "3. Get layers"

I'll save some OSM related links here, that I might use regularly. I could use Evernote but ... Oh well ;-)
