Adam,

 

You’ve got an interesting challenge on your hands!

 

Have you considered using other visual cues to indicate differences?

-          Outline type

-          Fill patterns

-          Labels

 

I know you’re probably doing this in desktop GIS, but I find this Javascript library really beautiful. Maybe it can serve as an inspiration.

Good luck!

Subject: color blind friendly mapping

 

The Project:

 

To replace a black and white, paper zoning map that is designed with hatch, line, and marker symbols with a colored version made with GIS that easy to keep updated. 

 

The Problem:

 

One of the main staff members who will use the map is color blind.  The map would require 10+ colors and the color blind friendly color ramps, can't handle that many variations in relation to this person's type of color blind.  I have looked at many resources and they have helped, but the number of zones and overlays still make the map hard to distinguish for the color blind person.  I would love to make one all-inclusive product, but that may not be possible.

 

The Questions:

 

1. Does any have experience or advice to help make this municipal zoning map color blind friendly?

2. Can anyone offer a creative solution, simple or high-tech, that could help this one staff member access the zoning information in another manner?  

2a. Is that an acceptable alternative and is it maintainable?

3. Should I follow the KISS rules and just convert the map to GIS and stick with a black and white hatch, line, symbol map?

 

Thanks!  I'll compile and share the results.

Adam
