Typo Typo is an experimental typeface based on topographic data from Colorado’s front range. Each letterform was found in USGS contour data and edited to create letters, numbers, and select punctuation. The data is from USGS 1/3 arc-second Contour Downloadable Data Collection. Using QGIS, I explored this data to find each character. From there, each character was image traced in Illustrator and then imported to font forge. A more detailed explanation of the process can be found here.
