Topographic maps use contour lines to represent physical terrain. Analyzing and interpreting data from such maps to describe patterns of Earth's features is often required by middle and high school science standards. However, because topographic maps and contour lines are 2D quantitative representations developed by simplifying real 3D land surfaces, some students without adequate visual input may have difficulty in understanding this abstract knowledge.
We are considering developing a product that may help students with blindness and low vision understand how contour lines are drawn and how topographic maps are used. This short survey is to collect some information about how such concepts are currently being taught to blind or low-vision students and whether it is necessary to add additional tools. If you know someone else who may also provide information about this topic, please help us by forwarding this invitation to take the survey. You can copy the web address and send it out in e-mails.
