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

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.

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 ....

Editorial: The Things We Gather
You can tell a lot about people by the things they collect. Whatever the motivation, for most of us the process of collecting is a pleasurable pursuit. Many of our writers own fine collections--old surveying instruments, classic cars, antique clocks, coins, photographs and more. Personally, I've ....

Using Google Earth I'm sure many surveyors like myself have downloaded and played with Google Earth.

Vantage Point: Life Behind Levees: an Overview and Update Throughout history, mankind's interaction with water has been a love/hate relationship. We have loved to be near water for drinking, bathing, fishing, watering crops, navigating our ships, and just plain aesthetics.

Since very few experienced persons were available for employment ....Read the Article

Laser Scanning Mushpot Cave The concept for this project was hatched in the brilliance-inducing state one achieves by moving rapidly between the dim, flickering ambiance of a GIS computer screen and the dim, flickering ambiance of a bat-filled lava tube cave, which were not dissimilar to the conditions in which I interned as a cartographic technician at the Lava Beds National ....Read the Article

Coping with Tectonic Motion Using GPS technology, surveyors can easily measure positional coordinates with centimeter-level accuracy. As a consequence of this capability, surveyors are now exposed to coordinates that change over time due to plate tectonics. In the contiguous United States (CONUS), the fastest changes in coordinates occur in California, because the state lies almost entirely within the boundary ... Read the Article

Vantage Point: Crawlspaces and Basements Surveyors have been having trouble describing buildings for the National Flood Insurance Program (NFIP) since time immemorial, or at least since the introduction of building diagrams to categorize general construction techniques. It seemed that every structure we encountered in the field fell between the cracks in terms of conforming to one or another of the proffered examples. The most recent ...Read the Article

Real Time GNSS Network in New Mexico Think RTK without a base station and you have a Real Time Network (RTN). No more shuffling through datasheets to find a nearby control point or doing recon for a station with unobstructed sky visibility and clear line of sight to the jobsite. No need to set up the unit in morning and tear it down in the evening. No more searching for an open frequency. Just get out of your vehicle and start surveying ....Read the Article

Vantage Point: On the Waterfront­—or Not Those who have deeds citing frontage on a body of water are very protective of that frontage. When natural phenomena such as avulsion, alluvium, or erosion change the physical proximity of a land parcel to water, we are generally familiar with the effect on boundaries. Of course rights along water boundaries are....Read the Article

Reconnaissance: Retracement Surveys and Undocumented Corners (Part 1 of 2) Recently I was dismayed by a discussion thread on one of the surveying bulletin boards that related to the perpetuation of a section corner and an undocumented monument that appeared to be marking that corner.
