Changes to National Park Maps
Tom Patterson, US National Park Service
I will report on the current status of brochure maps prepared by the US National Park Service, Harpers Ferry Center. Now that we have rebuilt most park maps from geospatial data, we are taking things to the next level by transforming them to the Web Mercator projection. It takes three to four hours to transform a typical park map from the UTM to the Web Mercator projection, a procedure that works well even for “high-latitude Alaskan parks,” really. Web Mercator advantages include simpler map updates, efficient data transfer between Adobe Illustrator and Photoshop (everything is rectangular), and exporting to web tiles. In other developments, we now publish park maps as geospatial PDFs on the Avenza map store and have greatly expanded the NPS Symbol library. I will also discuss recent accessibility efforts. We are converting park visitor maps to Braille and have developed tactile terrain maps.
This presentation was made at the 2017 annual meeting of the North American Cartographic Information Society (NACIS) in Montréal. For more information on NACIS, check out http://NACIS.org.
