New and Updated OpenStreetMap Editors

August 10, 2015 1 comment

Recent updates to Esri’s ArcGIS Editor for OpenStreetMap (OSM) add-on and a new OSM edit option in GitHub highlight the continuing popularity of OSM as one of the go-to base layers for many online mapping applications. In April this year, Esri announced the release of ArcGIS Editor for OSM 10.3x, providing an updated free and open source desktop toolset to download, edit and publish updates to OSM.

Two years ago we wrote about the then new option to upload and visualise geoJSON format spatial data in GitHub against a base map provided by OSM. GitHub have now extended the options for viewing and collaborating on spatial data sets to include the base map itself, with a new option to improve the underlying map for registered GitHub and OSM users.


Registered users can either edit the base map themselves or for those who haven’t registered with OSM, leave a note for another editor to review and resolve. Use of the OSM data remains subject to the terms and conditions of the Open Data Common Open Data Licence.






GitHub, geoJSON and geodata

July 1, 2013 1 comment

In addition to hosting open source code and supporting documentation, GitHub has recently announced support for rendering geographic data encoded in geoJSON, an open format for encoding geographic data that is supported by a number of popular mapping applications. This means any .geojson file stored in a GitHub repository will be rendered automatically as ‘…an interactive, browsable map‘ with the base mapping provided by OpenStreetMap. Topologically structured data are supported via the TopoJSON format. GitHub have also provided a javascript template to allow users to embed the data in their own javascript-enabled HTML pages.

Although many of the .geojson files currently hosted seem largely experimental, GitHub could develop into a useful spatial data resource and one to remember when searching online for open data.
