The Spatial Hub uses a range of open source and some proprietary technology within it's infrastructure. It has been designed so that it has minimal impact on data contributor's time and so that it helps meet the EU INSPIRE Directive obligations and specifications. It also links to, and works in conjunction with, the Scottish Spatial Data Infrastructure, which meets another aspect of INSPIRE i.e. a metadata discovery service. One of the key aspects of the Spatial Hub is the way that it enables the sharing of data over the internet using web services.
- A Web Map Service is a protocol for the serving of georeferenced map images. It is supplied as an internet URL but can only be used within GIS software or a web application (i.e. not through an internet browser). Only basic data attribution transfers can be made through WMS. Therefore it isn't as useful to a data users as a WFS, though it will normally render far faster. Multiple data layers can be provided within the same WMS - which is how the Spatial Hub delivers it's datasets to users.
- A Web Feature Service is a protocol for serving geospatial features. It is supplied as an internet URL but can only be used within GIS software or a web application (i.e. not through an internet browser). Unlike a WMS a WFS provides all geometry and data attribution to a data user's application. Therefore it can take longer to render the data. Multiple data layers can be provided within the same WMS - though the Spatial Hub provides a unique WFS URL for each dataset.
The Spatial Hub provides access to web services with authorisation keys. Each OSMA organisation has it's own unique authorisation key and each data contributor will need to register for their own log in details to be able to provide data in to the Spatial Hub.
