Welcome to NACIS 2014 in Pittsburgh! This is the annual meeting of the North American Cartographic Information Society (NACIS). The theme for this year’s meeting is Cartography and Time. See the schedule below and go to the NACIS website for more details.

[If you are a presenter and want to provide a link to your slides in your presentation description below, send an email to veep@nacis.org.]

The North American Cartographic Information Society, founded in 1980, is an organization comprised of specialists from private, academic, and government organizations whose common interest lies in facilitating communication in the map information community.

Curating the terrain
Travis White, University of Kansas
Aaron Taveras, University of Kansas
The authors have been invited to develop an exhibit on cartographic terrain representation for the University of Kansas Art & Design Gallery in the fall of 2014. Our goals for this exhibit are twofold: first, we wish to engage our audience in the processes used to transform "real" physical environments into cartographic depictions of those environments; second, we wish to challenge conventional notions about how the physical environment "should" appear on maps by comparing a variety of quantitative and artistic techniques for displaying topographic features. This talk follows the development of this exhibit from conception to actualization, drawing upon our own work and our key inspirations.

Small Scale Historical Landscape Reconstruction Using Vue
Erik Steiner, Stanford University
Before Hetch Hetchy Dam, there was Searsville Reservoir. Built in 1892 to supply the burgeoning city of San Francisco, the lake was never used as a water supply. Instead, the lake became recreation destination and eventually a part of a biological preserve where it sits today as a controversial source of habitat for dozens of species of bats and birds, but is 90% filled with sediment and blocks spawning opportunities for local salmonids.

This presentation reports on the cartographic effort (using Vue) to develop a small scale historical ecology (vegetation reconstruction) of the area around Searsville Reservoir as it existed before it was settled by Europeans and before the construction of the dam. Reminiscent of the Manahatta Project (on a much smaller scale), our goal is to help visually untangle the delicate restoration decisions that will determine the long term future of this watershed.



The Technology Evolution of Raised-Relief Maps
Michael Higgins, Summit Terragraphics Inc.
This paper traces the evolution of the raised-relief maps and terrain physical modeling from its earliest forms to today’s use of modern technology, including CNC routing and 3D printing. The first half of the paper reviews the beginning of 3D maps using primitive materials and then progresses through more elaborate and durable materials and forms such as hand painted and sculpted clay models. The newest production forms are then also reviewed – CNC milling/routing with digital printed surfaces, 3D color printing, and precision thermoform molding of plastic sheets.



Visual illusions in Cartography
Arzu Çöltekin, University of Zürich
Some visual illusions are exteremely important for the legibility and interpretation of cartographic products; such as the terrain reversal effect in shaded relief maps (in which we perceive convex shapes as concave and vica versa), or change blindness (in which we can't detect the change from one scene to another). Some others, such as Müller-Lyer illusion or Ebbinghaus illusion may also be relevant in estimating distances and areas. This talk provides a brief overview of illusions in Cartography and presents results from an empirical study on terrain reversal effect.

Michael Higgins

President, Summit Terragraphics Inc.
I founded Summit Terragraphics 6 years ago to take advantage of the wealth of new geo data and terrain-model manufacturing technology and apply it to raised-relief maps. Summit brings increased precision and accuracy to thermoformed raised-relief maps by using high-resolution elevation and imagery data combined with new manufacturing methods such as 3D Printing. Summit's sole business area is raised-relief mapping, and we're pleased to join... Read More →
