Tom Patterson, US National Park Service Cartographer (Ret.), will present a virtual talk, “Mapping Grand Canyon National Park,” on Thursday, April 8, 2021 at 4 pm PDT.

Patterson’s presentation will focus on four recently published maps of Grand Canyon National Park that owe their design inspiration to renowned mapmakers of the twentieth century.

This will be the 31st annual Maps & America lecture, supported by an endowment created by Arthur and Janet Holzheimer.

The lecture series was inaugurated by the noted cartographic historian, Brian Harley, in 1990. Over the years, the series has featured many of the leading figures in the field of map history and provided a multifaceted survey of this rapidly developing field. A list of previous speakers can be viewed here.

The National Map Corps

The National Maps Corps is an online crowdsourcing mapping project with volunteers successfully editing structures in all 50 States, Puerto Rico, and the U.S. Virgin Islands. Structures include schools, hospitals, post offices, police stations, cemeteries, and other important public buildings. By updating and verifying structures data, volunteers are making significant contributions to USGS National Structures Database, The National Map, and ultimately US Topo Maps.

Mercator’s World

Geographical maps are a mirror of what we know about the world around us. Few individuals contributed more to the map making field than cartographer Gerardus Mercator. Check out this site that examines Mercator’s map making breakthroughs and mistakes, while also recognizing his lasting legacy. We still use Mercator’s projection for making nautical and aeronautical charts!
