Hi, my recommendation in addition to standard WCAG advice would be to:
* Allow users to filter data layers to focus on certain aspects
* Allow users to request information by a location or address
* Allow users to get directions or steps by putting in two or more locations - e.g. safe route in text directions to evacuate, etc.
* Present information in different ways not just visually
* Allow users to control presentation of the data - for example - colors/patterns, etc. that work for them
* Support large text - generally in maps as you zoom in text can get smaller or stay the same size.
* Support symbols/legends - both text and non-text options.
* Other supports

Hello WebAIM List folks,
We are using ESRI ArcGIS Web AppBuilder to create an Emergency Portal for the public. It will include maps to communicate during "blue-sky" days as well as specific emergencies (e.g. widespread power shut offs, fires, earthquakes, flooding...). There are many, many attribute layers that may or may not include important accessible information. Depending on the emergency will depend on which layers are turned on. (e.g. flooding, road closures, etc.) There may be more than one map (still being discussed). We want to provide the information in an accessible format for screen reader users, people who are in a panic and may be easily overwhelmed, folks who may not have the latest mobile technology to use the map, etc.

Do any of you have experience with the best solution? Or can recommend resources, site example or? What is the best way to manage such huge volume of attribute information?

thank you for your time,
Suzanne
