OS OnDemand is Ordnance Survey's web map service, delivering the most up to date map data directly into an organisation from our database. It provides a simple way to access our trusted mapping and local information, giving you a single view of the data across your entire organisation. So it doesn't matter if you're sat side by side or at opposite ends of the country, you can be sure you're viewing the same information. OS OnDemand allows you to quickly pan and zoom, letting you view the mapping in great detail, as well as combining data that's relevant to your business.
OS OnDemand is compatible with most GIS software packages and these videos show you how to connect to the service through some of those packages including ESRI.
To use the software, the first step needed is to map to OS OnDemand through ArcCatalog. Once in ArcCatalog you will need to find the GIS server and then add WMS server. Copy in the url given to you as part of the welcome information so that you can access OS OnDemand and then click get layers. You will then be prompted for a username and password. The available layers will now be shown. The OS OnDemand WMS will now appear on the list of GIS servers. You can use the properties field to change the name of the WMS if you want.
You will now need to open ArcMap to view the OS OnDemand WMS data feed. You will be prompted to add the map layers by selecting the OS OnDemand server.
You will then be able to:
• pick what datasets you want to show
• zoom into the map to see your different map layers at different scales.
• lay your own information, such as points lines and features on top of the map.
• change how the information is presented using your GIS functionality.
