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 (useful for web maps). Multiple data layers can be provided within the same WMS - which is what we do for some of our datasets that comprise more than one layer (e.g. school catchments).
- 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.
The Spatial Hub provides access to web services with authorisation keys (apart from Open Government licenced datasets, which are totally open). Each OSMA organisation has their own unique key.
Local authority data custodians and providers, who have a responsibility for regularly uploading data to the Spatial Hub, require login credentials (user name and password) to access the UPLOAD DATA pages. Once logged in they should have access to any dataset that they are required to add data to.
Details about how to upload data to the Spatial Hub or use Spatial Hub web services are provided in the videos below.
