a city or neighborhood) for offline use or publishing in your own portal. Because the data is published as feature layers, they will support visualization and analysis, including the planned ability to extract selected areas of the data (e.g. These feature layers will be hosted in ArcGIS Online and configured to scale. This year, Esri is introducing a new set of feature layers that provide access to OSM data. These basemaps are ideal for high-performance visualization but have limited capabilities beyond that. This started with Esri referencing raster tiles hosted by OpenStreetMap and has evolved to Esri generating and hosting vector tiles, which are updated every 3 weeks with the latest OSM data at the time. For several years, Esri has provided access to OSM data as a basemap. The data is available under the Open Database Licence, please refer to License/Terms: or (OSM) is an open, editable map of the world.

In this series of blog posts we will be discussing these in more detail and outlining how TfNSW is providing customers with better and more accurate data. In the last year, Transport for NSW has started using OSM for various applications and projects. OSM allows you to export maps in various formats including image files, embeddable html and map files.Īs you can see, OpenStreetMap has a huge range of uses and lots of potential. This is very useful because you can create your own datasets and publish those on your open data portal such as the Open Data Hub. Niantic for their very popular games Ingress and Pokémon GoĪnother feature of OSM that is very useful is that you can create a custom map, for example by adding layers or points, and then export that map as a dataset.There are many use cases for OSM including base maps, custom maps, routing, analysis, research and applications.

Custom maps can also be generated from the OSM website or through various software including Jawg Maps, Mapnik, Mapbox Studio, Mapzen's Tangrams. OSM can also be viewed by a range of open source software or tools such as OsmAnd, or GNOME Maps. Tags are not free-standing, but are always attached to an object: to a node, a way or a relation.ĭata provided by the OSM project can be viewed in a web browser simply by going to. They are used to store metadata about the map objects (such as their type, their name and their physical properties).

Tags are key-value pairs (both arbitrary strings).

Relations are used for representing the relationship of existing nodes and ways.

Relations are ordered lists of nodes, ways and relations (together called "members"), where each member can optionally have a "role" (for example “from” or “to” when talking about directions).

Ways are ordered lists of nodes, representing a polyline, or possibly a polygon if they form a closed loop.

Nodes are points with a geographic position, stored as coordinates (pairs of latitude and longitude coordinates).

OSM uses a topological data structure, with four core elements (also known as data primitives): While OSM aims to be a central data source, its map rendering and aesthetics are meant to be only one of many options, some which highlight different elements of the map or emphasise design and performance. Government agencies are also great contributors with many departments submitting their own data under open data policies. Data can also come from other open platforms such as Mapillary or OpenStreetCam. The project has a geographically diverse user-base, due to the emphasis of local knowledge and ground truth in the process of data collection. The data is then entered into the OSM database.

Map data is collected from scratch by volunteers performing systematic ground surveys using tools such as a handheld GPS unit, a notebook, digital camera, aerial photography, or other free sources.

The data from OSM can be used in various ways including production of paper maps and electronic maps (similar to Google Maps, for example), geocoding of addresses and place names, route planning and for applications and software. This crowdsourced data is then made available under the Open Database License.

Since it began, OSM has grown to over two million registered users who can collect data for the platform. OSM was created by Steve Coast in the UK in 2004 after being inspired by the success of Wikipedia and the rise of proprietary mapping data and tools across the world.

OpenStreetMap (OSM) is a collaborative open source project that aims to create a free editable map of the world.
