Astun Data Services - ADS v1

Overview

Astun Data Services provide a range of geographic data as web services for consumption as Base mapping within web mapping and desktop GIS applications.

The use of Astun Data Services provides a cost-effective and resource-free alternative to translating, storing, updating and serving base mapping data to internal and public users.

Astun Technology are happy to extend ADS to include custom Aerial Photography or Raster maps; which we have done for several customers already.

BaseMap Data Services

Managing Ordnance Survey base map data and imagery requires specialist software and can be time consuming. Astun Data Services offers a simple low cost alternative for PSGA members (or those with an alternative OS licence) to access national cover (or a licenced subset) of MasterMap and other data sets, including OS OpenData as WMS, WFS or WMTS and a vector download service with a number of  attractive cartographic styles.

BaseMap Data Services include national coverage of the following datasets.  Map data is available in British National Grid (BNG) as an Open Geospatial Consortium Web Map Service (OGC WMS) or a Tiled Map Service (TMS) with 15 levels of zoom.

Blank BaseMap

Numerous iShare users have expressed an interest in a ‘blank base map’, particularly for use with iShare GIS and printing. This allows the end user to easily focus on the data and layers displayed via iShare GIS and iShare. A particularly nice feature of this map base is the ability to change the colour of the the ‘blank base’. To change the background colour of the Blank base please refer to Change the ADS Blank BaseMap Colour.
