This is the official accessibility statement for the Digimap service.
It applies to each Digimap Collection. If you have any questions or comments,
feel free to contact us on digimap@ed.ac.uk.
Access keys
Most browsers support jumping to specific links by typing keys defined
on the web site. On Windows, you can press Alt and an
access key; on Mac, you can press Ctrl and an access
key (depending on which browser you use).
Access Keys for all pages in the Digimap Service are defined as follows:
Where applicable, pages in this service use structured semantic
markup. H1 tags are used for main titles, H2 tags and lower for subtitles.
The downloadable maps and data are not encoded for accessibility.
Please see the section "Accessibility of downloaded maps and
data" below for more details.
Navigation
Every application page has a global toolbar. This precedes the
main content of the page, and can include the following links: "Contact
Us", "Help" and "Log-Out". These links all
open in new windows when opened in a JavaScript enabled browser.
The help page works by a series of expandable links on the left
side of the browser. Relevant help pages can be accessed from each
of the headings. The help page is context sensitive as accessing it
from pages within the Digimap service will take you to the most relevant
title or section.
Links
Links are written so that they make sense when read out of context.
Where images are used as the link item, the alt text of the image
should be the same as the title text for both the image and the link.
When a link leads away from the web site, a new browser window
will open. This should be noted in the title of the
link.
Images
Any content images used in this service include descriptive alt
attributes. Purely decorative graphics include null alt
attributes.
Visual design
Marine Lexicon uses tables for visual layout. Where used solely
for layout purposes, table headers are not used, and no summary attribute
is used.
This service uses only relative font sizes, compatible with the
user-specified "text size" option in visual browsers.
Style sheets are used to designate font size and colour, both in
"ordinary" text and linked text, and background and other
visual layout aspects of tables.
If your browser or browsing device does not support stylesheets
at all, the content of each page is still readable.
Accessibility of downloaded maps and data
Owing to the nature of the maps available through Digimap it is not
possible to offer an alternative for the visually impaired. Maps displayed
on the website are identified as a 'Clickable Map' and have their extents
in coordinate form in the alt attributes. Data available
through Digimap is intended for use in a user's own application software.
Problems with Accessibility
We at EDINA have tried to make the Digimap service as accessible as
possible within the constraints of technology and cartographic data on
