ADA Compliant Map PDFs

In ArcMap or ArcPro: Export map to PDF without layers (flattened) when possible. Tagging can make items disappear from layered files.

Export Map > Options > Advanced Tab (in ArcMap) > Layers & Attributes = None

In Adobe Acrobat Pro DC

Create Tags

  1. Open Tools > Accessibility > Reading Order (or Touch Up Reading Order - TURO).
  2. Treat the entire map and legend as one figure. Select it by dragging the cursor and draw a box around all of the map and legend but not the title, then choose "Figure" from the Reading Order panel. If parts of the map disappear, close out – don’t save. Go back in and make sure to draw the box around everything including the map frame and legend frame, then hit Figure.
  3. Select the title by drawing a box around it, then choose Text (or a Heading).

Note: Design your pages so this text is outside the map area and easy to select.

Tips:

  • If you mess up a page or a document comes to you with messy tagging, select “Clear Page Structure” and then follow the above steps.
  • If you need to select things that overlap, select and tag the larger item first, then the smaller.
  • If want to deselect something within another item, hold down the Control key while selecting.

Add Alternative Text to Figures

  • Must be done after map is Tagged
  • Entire document: Tools > Accessibility > Set alternate text > OK.
  • Acrobat will find each figure and provide text boxes with arrows to scroll through.
  • Alt text should convey the message of the map. Keep important detail outside of the alt text. Keep the alt text brief. A short alt text should indicate the type of figure and then reference more detailed descriptions in the caption or body text.
  • Save & Close
  • Close Accessibility ( X at top right)
  • Save PDF
