The Government Agency I work for, Geoscience Australia, produces many applications of this type and I would like to know what effect we will have if we adopt these guidelines. An example of a particular mapping application we host can be viewed at

Response from the Working Group
There are no exclusions for complex non-text content such as
geospatial maps. However, if your example is typical, the "Recent
Earthquakes" link provides a long description of the information
provided by the map. In addition, your example provides an alternate
version of the data used to generate the map via the search feature.
The map could contain a short description that indicates what kind of
data it contains and tells the user where to find the longer
description. See Situation B in Understanding Success Criterion 1.1.1
for similar techniques.
