Geographical Information Systems (GIS)
All web-based Geographical Information Systems (GIS) should conform with all WCAG 2.0 AA requirements. They must conform with WCAG 2.1 AA technical accessibility standards by April 24, 2026.
This adjusted requirement is from a new rule in Title II of the Americans with Disabilities Act (ADA). It takes precedence over the current Texas Department of Information Resources (Texas DIR) exemption. The GIS exemption has been under review. Texas DIR plans to provide some guidance in making GIS-based platforms accessible.
