Section 508 Compliance and Geographic Information System (GIS)-based Figures
At present, the accessibility of GIS in compliance with Section 508 of the Rehabilitation Act is limited. The inherent graphical nature of GIS and the volumes of data represented make compliance difficult. EA maps developed from GIS software currently do not meet the full Americans with Disabilities Act (ADA) and Section 508 accessibility requirements. If you use assistive technology and the format of these pages prevents you from obtaining necessary data, please contact the Webmaster
