303-776-9900In the world of special districts, complex mapping, design, and engineering are part of daily operations. District managers, fire chiefs, board members, and engineers frequently rely on highly technical documents—rich with data, diagrams, maps, and intricate specifications. From AutoCAD schematics to GIS zoning maps, much of the information shared with the public is inherently detailed, which makes ensuring accessibility a uniquely challenging task. Yet, with the sunsetting grace period, even these specialized materials must meet accessibility standards, requiring districts to rethink how they present critical information to make it navigable for all.
A common misconception is that special districts aren’t required to comply until July 1, 2025. However, this isn’t entirely accurate—compliance is required now, with a grace period extending until that date.
Colorado is leading the way in advancing accessibility for public sector websites, setting an example for other states. But with this leadership come unique challenges. Districts must ensure not only that basic text and images are accessible but also that technical documents like GIS maps and AutoCAD drawings comply with accessibility standards. Because these documents are inherently visual and involve complex layers of data, ensuring they are usable by assistive technologies can present significant hurdles.
The Web Content Accessibility Guidelines (WCAG), published by the World Wide Web Consortium (W3C) and adopted by Colorado’s Office of Information Technology (OIT), are widely accepted as the gold standard for web accessibility. These guidelines offer direction on how to make web content—including technical documents—more accessible for users with disabilities.
Making Complex Digital Assets Accessible
Here’s what you need to know about tackling accessibility for GIS maps and AutoCAD documents:
- GIS Mapping Systems:
GIS maps are essential tools for visualizing geographic data, such as utility networks, service area boundaries, and zoning. However, their interactive layers and dense data can be difficult for screen readers and assistive technologies to interpret. - AutoCAD Documents:
AutoCAD files are frequently used for infrastructure designs and engineering plans. These highly visual documents, often shared during public planning or infrastructure development, pose significant accessibility challenges.
Strategies for Accessibility
While achieving full accessibility for these complex documents may be daunting, the following strategies can help:
- Provide Alternative Formats:
Offer alternative formats for complex documents. For GIS maps, this might include text-based descriptions or downloadable PDFs summarizing key information. AutoCAD drawings can be paired with descriptive documents that explain their content in plain language. - Ensure Accessible Map Interfaces:
For interactive GIS maps, work with developers to ensure the mapping tools themselves are accessible. This includes enabling keyboard navigation, providing alt-text descriptions, and ensuring all features can be accessed without relying solely on visuals. - Add Descriptive Text for Key Features:
Accompany visual elements, like service boundaries on a GIS map, with text descriptions that include coordinates or addresses. This ensures users who cannot interact visually can still engage with the content. - Offer Data in Accessible Formats:
Make datasets (e.g., shapefiles, tables, geographic data) available in accessible formats, properly tagged to ensure compatibility with screen readers. - Use Accessible Viewing Tools:
When embedding GIS or AutoCAD files on your website, ensure the viewing tools comply with accessibility standards. Many third-party tools offer accessible viewing options, enhancing usability for all. - Create Video Walkthroughs:
For highly complex materials, consider creating video or audio walkthroughs to narratively explain the content. This approach can help users grasp the key points of technical documents without needing direct interaction. - Leverage Clear Labels and Alt Text:
Ensure all icons, layers, and visual elements within GIS or AutoCAD files are clearly labeled and accompanied by alt-text or descriptive metadata.
A Commitment to Equal Access
For special districts, web accessibility isn’t just about legal compliance—it’s about ensuring all community members can access essential public information. For districts working with intricate GIS maps and AutoCAD files, achieving accessibility may require extra steps. Yet, these efforts are critical to fostering equal access to public resources and services.
