Publishing third-party data in ArcGIS Online

 

This page provides information how third party data and services can be linked to ELF. The ArcGIS Online documentation provides comprehensive online documentation on publishing data. 

 

A significant amount of third-party data is already published so that it is available to users of ArcGIS Online and ArcGIS in general. The ArcGIS.com map viewer supports searching for layers or browsing map layers provided by Esri and others

 

To make third-party data that is not yet accessible in the platform available to targetted users of ELF, there are several options that are described here. Note that data that has no explicit geometry, but latitude/longitude or address columns can also be added and be automatically geo-referenced.

 

Data that has no explicit geometry, but that includes references to feature of thematic identifiers of geospatial reference data from ELF, e.g. referencing a road link in an ELF dataset or a NUTS code, needs to be processed to geo-reference it. This is a subject that will be looked at in more depth in the ELF project as it is an issue that occurs in ELF/INSPIRE data, too. In particular, features that represent properties of a transport network are only indirectly geo-referenced in INSPIRE.

 

In addition to publishing data as hosted services in ArcGIS Online (similar to the ELF services), data that is made available via ArcGIS Server, OGC WMS or WMTS, or as KML files from elsewhere can be used in the ArcGIS platform directly, too.

 

Like most mapping platforms on the web, ArcGIS uses WGS84 with the Web Mercator projection ("Pseudo Mercator" in the EPSG register, code 3857) for map display. Third-party map services published outside of ArcGIS Online should support this coordinate reference system to allow combining such third-party data with ELF data or Esri-provided maps.

 

web map  is a key concept in ArcGIS Online that combines a base map and a related set of layers that users can interact with to perform a meaningful task. This is a key concept of ArcGIS Online and allows to combine data from multiple sources, e.g. ELF and third-party data, and share it with others. Applications also build on web maps.
