It is likely you have never heard of Paul Mathews, but if you ski it is probable that you have been on a slope that he had a hand in designing. In 1975, he founded Ecosign Mountain Resort Planners, “Ecosign” being a portmanteau of ecology and design. Whistler, the downhill and backcountry ski hub in British Columbia, has been his home turf since the 1970s, and Ecosign has worked on more than 400 ski resorts around the world.

Mathews was responding to the state of skiing in the 1970s when he founded Ecosign. Ski areas had evolved over the years, some growing from ad hoc paths down the sides of mountains into massive areas, choked by car traffic on the weekends, full of stairs and narrow, poorly designed ski slopes, or pistes, with disorganized ski villages at their base. Infrastructure was insufficient; environmental degradation was rife. Some resorts were made by tearing into the landscape, moving large amounts of rock and soil, cutting excessive numbers of trees, ignoring flora and fauna. Few undertook adequate transportation planning to handle weekly visitor flows. Other ski areas suffered from fragmented ownership, with multiple operators in single small town or village settings, hampering the investment needed to keep facilities modern and ensure longevity and employment. Four decades after founding Ecosign, Mathews knows what to do with both challenges—how to plan for sustainable futures and growth and how to establish completely new ski resorts in places that have none. The company is about 20 people and includes landscape architects, architects, engineers, soil scientists, and MBAs, among others, who work around the world from Ecosign’s base at Whistler. “There is lot of work in China, the Balkans, Turkey—anywhere where they have mountains, snow, and incomes that are rising,” Mathews says.

3-D Scanning and the holographic landscape.

FROM THE JANUARY 2017 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE

It’s been more than a decade since Google Earth put 3-D mapping in the hands of anyone with an Internet connection. Now, armchair map geeks can fly through the skyline of virtually any city in the world to check out, say, the architecture of the Louvre or take a virtual stroll through the Jardin des Tuileries using Google Street View. The ability to cost-effectively produce such imagery on a global scale stems in part from advances in 3-D scanning, a term of art that encompasses LiDAR (light detection and ranging), drone-based photography, ground-penetrating radar, and other advanced imaging technologies.

Three-dimensional scanning has become so inexpensive and user-friendly that design firms are starting to experiment with it. Architects and engineers use it to help create as-built drawings of bridges and buildings and for “clash detection” when designing additions or renovations of historic structures. Urban planners use it as a visualization tool when modeling different development scenarios. Anything that can be 3-D scanned can be 3-D printed, and (more…)
