Its short institutional life at Harvard was replete with materials, stories and scandal, and its pieces remain scattered today throughout the Harvard Archives and Libraries system and beyond.” Ana Luiza Nicolae tracks down what records, photos and other materials can still be found on the Harvard campus that once belonged to Alexander H. Rice’s HUIGE, which was not closely affiliated with Harvard’s geography department but was shut down at roughly the same time.

Mapping Denali in Detail https://www.maproomblog.com/2018/05/mapping-denali-in-detail/ Thu, 17 May 2018 22:39:38 +0000 http://www.maproomblog.com/?p=1785619 More]]>

Matt Nolan and his family have created a topographic map of Denali, the highest peak in North America, using a form of stereo photogrammetry Nolan calls fodar: they repeatedly overflew the peak in a small airplane and took photos of the terrain below with a digital SLR. The end result is a 20-cm terrain model they’re touting as the best ever of the mountain, far more detailed than previous maps. Nolan outlines their endeavour in two blog posts: one focusing on the personal, the other on the technical; the latter also has lots of terrain models and comparisons with USGS data.

He’s also running a crowdfunding campaign to underwrite the costs of additional map flights. [WMS]
