Text sizing

This site is constructed using relative font sizes, which means that text can be scaled within the browser. Please refer to your browser's help page for information on how to achieve this.

Images

All images used in this site include descriptive "alt" attributes. Where images are used for layout purposes, an empty "alt" attribute is used.

Forms

All forms and their fields are labelled and arranged into logical groups where possible.

Frames

Where the use of inline frames (Iframes) is employed, due to technical requirements, these are clearly labelled in order to make access to them as easy as possible.

Links

Unless notified, all links open within the same browser window. Should you wish to open a link in a new browser window then hold down the "SHIFT" key while activating the link required. When linking to an external site Ordnance Survey cannot be held accountable for the content of that site.
