The vision of the founding members of ASPRS was farsighted indeed. Their 1934 mission to advance knowledge and understanding of the mapping sciences today encompasses a broad spectrum of scientific, social and commercial enterprises. To complement the timeline in this month's American Surveyor article about ASPRS, we've included some exciting info about today's cutting-edge aerial imaging technology in the following pages. Even more exciting is to see these solutions in person (along with a whole lot more)! Make plans now to meet the movers and shakers behind all the new ideas and technology and see what lies ahead for this industry by attending ASPRS 2010 in San Diego, California (April 26-30).

LizardTech's LiDAR Compressor
In another of a long line of productivity tools, and responding to long-standing requests, LizardTech announces the release of LiDAR compression for industry-standard MrSID. Designed for LAS and text files, the Generation 4 (MG4) format offers two compression levels. The first will result in a 75 percent reduction in file size while retaining all the points and precision and accuracy of the original file. The second virtually lossless level can reduce file sizes by 90 percent, and contains less root mean square error than the sensor that captured the original data.
The software readily handles huge point clouds generated by airborne or terrestrial laser scanners, and allows users to easily extract derivatives.
Optech's ALTM Products
Optech's prominence as a world leader in the development and manufacture of advanced laser-based survey and imaging instruments extends over the last 35 years. Throughout, Optech has worked closely with academic, government, military, naval, air force and space-based organizations to meet their specialized application needs.
As a pioneer in the field of LiDAR imaging and ranging technology, Optech developed the world's first commercial airborne laser terrain mapper, now known around the world as ALTM. Available in both application- and platform-dependent configurations, Optech ALTMs offer the greatest flexibility and efficiency available to the professional surveyor today.

Editorial: America the Beautiful
After a rough wagon ride up to Pikes Peak in 1893, it was the view from the top that inspired Katharine Lee Bates to write a poem that became known as "America the Beautiful." Later set to music by Samuel Ward, its images have become part of our national conscience. Few there are who cannot sing at least one stanza of the four. It's no secret to .... Read the Article
Brass Caps and Bandanas—Monumenting Anaktuvuk Pass
The Inupiaq are Eskimo people that live along the Arctic Ocean coast of Alaska's North Slope. In the last few hundred years a nomadic splinter group of the Inupiaq known as the Nunamiut moved inland away from the coast to follow the Caribou migrations and settled at Chandler Lake and the Killik River in the ....

GIS Mapping—Campus Style
When Craig Moore switched from the academic side of Virginia Tech in October 2004 to become an engineer for site development in the campus' Facilities Department, he inherited a GIS that was not easily updated, and maintaining it was a problem. As a result, "it trailed off to nothing," he said. At that time the system focused on ... Read the Article

According to renowned economist Hernando de Soto, the inability of persons worldwide to gain formal recognition of their real property rights is a major stumbling block to alleviating poverty. This lack of formal legal recognition of property rights is ... Read the Article
A Dividing Line Brings Us Together
Oh, the lines. The shortest distance between two points? A line pulled to ring a bell? A colonial boundary between two long forgotten counties? Lines of dialog in a television documentary?

Conference Review: Leica HDS 2009—Simplifying the Complicated
When GPS technology first began to filter into survey work, it was necessarily complex, depending, as it did, on satellites, atomic clocks, relativistic equations, and the like. Surveyors took this in stride and accepted that working with such arcane magic would always require expensive equipment, lengthy training, and endless hours of .... Read the Article

Vantage Point: Going Out with a Sigh
The story I'm about to relate took place over the space of seven months, and the outcome ratcheted up so much emotion that it was impossible to write at its last turning point. On October 1, 2009, the backhoes revved up their engines at 8 A.M. sharp, the earliest time allowed for such noise in my township, and La Ronda began falling to ... Read the Article
