Editorial: Polarization
The ninth meeting of the Space-Based Positioning Navigation and Timing advisory board, held in Alexandria VA on November 9, 2011 was widely anticipated as a "showdown" between the anti- and pro-LightSquared forces. While the meeting scored points for both sides, it left unanswered some of the most important issues: the upper spectrum band, and who will pay. Those who are just now ....Read the Article

Rendezvous 2011—Altered Contours From sometime around 1000 BC through 500 AD, natives piled great quantities of dirt into all shapes and configurations within the valley of the great river. What was the purpose of these mounds of fill shaped over fifteen hundred years in the south-central region of present day Ohio-- Religion? Artistic expression? A means of hunting, securing necessary ....Read the Article

Vantage Point: A Homeowner's Setback Minnesota's Supreme Court recently struck down earlier decisions favoring a homeowner's complaint against the local city for errors related to the homeowner's shed. While Dr. Rajbir Sarpal and his wife Dr. Carol Sarpal had prevailed in the district and appellate courts, this May 2011 opinion (797 N.W.2d 18) remands the case back to district court, primarily regarding the point of equitable ...

Footsteps: Finding the Courage to Say "No" My father died in May. He was 52. The loss of someone close to you, especially your father, forces you to examine your life. You ask, "Am I following the moral principles that I was raised with, even when I'm under pressure to compromise?" This loss in my life and three recent situations I observed in my career as a land surveyor have prompted me to write this article. Boundary surveying is a branch of ... Read the Article

Conference Review: CGSIC and ION 2011—GPS-Greater than the Sum of its Parts The 51st Meeting of the CGSIC and the ION GNSS 2011 was held September 19-23, 2011 in Portland, Oregon. I can think of no better combination of conferences that serves to illustrate (to paraphrase Aristotle) how the "whole" of GPS/GNSS is certainly "greater than the sum of its parts". These two events are "the" place to interact directly with the constellation operators, policy makers ...Read the Article

Collect data on enough individual points to create a meaningful model of the space so that it can be designed and built for warehousing and storage. The challenge would be ....Read the Article

A Colonial Surveyor in President Jefferson's Public Lands
My apologies to Mark Twain, as in parts of my journey to obtain CFedS Certification I felt like the Connecticut Yankee, in King Arthur's Court, but in reverse. That is, I was the learner and my predecessors were the teachers. Also, my appreciation for American Surveyor Magazine's motto "A Foot in the Past...An Eye to the Future" prompted me to write about the journey that I recently ....Read the Article

Editorial: Putting the Lean On Manufacturing—A Visit to Topcon
The manufacturing area of Topcon's US headquarters in Livermore, California was a veritable beehive of activity during my recent visit. Colin Kavanagh, Senior VP for Operations, called attention to the "lean" manufacturing processes that have "eliminated expenditures for resources for any goal other than the creation of value for the end customer". To achieve this, Topcon cast a critical eye on ....

Surveying with Google Earth Over the past few years, I have become convinced that Google Earth represents an extraordinary opportunity to visualize and communicate survey data, though I too was skeptical of its value as a professional land surveying tool in the beginning. At the time, Metzger + Willard, Inc. (MWI) was making AutoCAD base maps with orthophotos in the vicinity of NGS control stations. Our reasoning was that, equipped with .... Read the Article

Conference Review: Hexagon User Conference 2011 What is Hexagon and what is the business of Hexagon?

Driving the Islands When the Public Works department for Washington state's San Juan County was challenged with identifying and mapping roadside assets in an effort to improve traffic safety, it responded by sending out crews with hand-held GPS units. They quickly realized both the scope such a project entailed and the overall inefficiency of using that technique. Knowing the importance of the effort, however ... Read the Article

Footsteps: Changes to the 2009 Manual of Surveying Instructions In a previous article, published online in June 2011, I discussed why the 2009 update to the Manual of Surveying Instructions was needed and how the BLM implemented it.

What follows here are highlights of some of those changes in the 2009 edition of ... Read the Article

Vantage Point: Noticing a Dirty Past Accutherm, Inc. manufactured thermometers containing mercury in Franklinville, New Jersey until 1994. It notified the state's Department of Environmental Protection (NJDEP) of its ceased operations, NJDEP issued cleanup orders to Accutherm, and when Accutherm didn't comply, the site was referred to the federal Environmental Protection Agency (EPA) for an assessment. The EPA's 1996 report .... Read the Article

Surveying `Da Situation: An Unexpected Gift
I believe we have all heard stories or had personal experiences of feeling as though someone close that we have lost reached out to touch us in some way. I had just that kind of experience recently. Back in the mid 1960s, my Dad was a deputy in the local sheriff's department. He had that job for several years until he found another one that paid a little better and freed up his weekends. Well, the county ....
