Tactile symbols for production on a 3D printer: 3D Rendered
================================================================================
================================================================================

The symbol set was designed for production on microcapsule paper by Amy Lobben 
and Megan Lawrence as described in the publication: 

Lobben A, Lawrence M (2012) The use of environmental features on tactile maps 
  by navigators who are blind. The Professional Geographer 64(1):95-108. 
  doi: 10.1080/00330124.2011.595619

The symbol set developed by Lobben and Lawrence (2012) was designed and 
evaluated as produced on microcapsule paper.  Those same symbol shapes were
modeled in low relief for production on a 3D printer.

3D RENDERED
Rendered stereolithograph (STL) graphics need to be processed using printer-
specific software prior to printing.
