Accessibility is the degree to which software is accessible to people with disabilities. Web Content Accessibility Guidelines (WCAG) 2.1 AA is a technical standard with the goal of providing a shared standard for web content accessibility. The Web Accessibility Initiative – Accessible Rich Internet Applications (WAI-ARIA) 1.1 is a technical specification that aims to increase the accessibility of rich internet applications with dynamic content. Both standards were developed by the Web Accessibility Initiative of the World Wide Web Consortium (W3C). VertiGIS Studio Web conforms with the WCAG 2.1 Level AA standard and aims to follow WAI-ARIA 1.1 keyboard navigation guidelines.

VertiGIS Studio Web offers the following accessibility features for end users:

•Screen Readers: Run a screen reader to vocalize and interpret page content.

•Keyboard Shortcuts: Interact with the viewer using only the keyboard.

•Skip Links: Navigate directly to a component by pressing ALT+Q.

These features can be used together.
