Hurricane Sandy reminds us to donate to NSPS Foundation Disaster Relief Fund
NSPS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Here we go again. Hurricane Sandy hit the East Coast with a vengeance. The Foundation stands ready to provide disaster relief funds to surveyors and their employees who have been affected by the storm. With such devastation from the storm, we are concerned our current funds will be depleted in such a short period of time that we won't be able to assist many who need help. More

Boundary issues vs title issues, and line weights
NSPS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
What do you do when there is a gap or overlap between the boundary you are surveying and its adjoiner? Do you feel you must — or should — resolve the issue by determining the junior/senior relationship? Is this really a surveying issue? Or is it a title issue? The answer is not always as it seems and, in fact, the controlling deed may not even be the one that was recorded first!

Can/should the line that is believed by the Surveyor to be the correct property line (based on an analysis of record, field, parole, etc. evidence) be shown on the plat in the same bold line width as are the other non-disputed property lines, as long as any potential conflicting alternative boundary lines are shown in a different line weight/width along with references to deeds, notes, etc?

The North Carolina Board of Examiners for Engineers and Surveyors was recently asked to address these questions, and has instructed Surveyors that they should avoid representing on the survey a professional opinion on title as to the relative weight to be given one line over another. A letter from the Board to the North Carolina Society of Surveyors notes that the Surveyor should not represent or imply that one boundary line is more significant than another by using potentially confusing line weights, stating in part that "Only if the Surveyor is able, through research and by applying the tenets of survey construction, that the line is in fact the correct boundary line and any other line is not correct, then the determined line may be represented as the boundary line."

Entering the international market
Professional Surveyor    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A recent economic survey of the members of MAPPS found that U.S. firms view the international market as a bright spot in the demand for geospatial data products and services. However, entering the international market can be a difficult and time-consuming endeavor. Here are a few tips most experienced exporting professionals say are essential to successfully performing surveying or mapping overseas. More

A safe habitat
Point of Beginning    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Meandering between Pennsylvania, Delaware and New Jersey, the fresh water of the Delaware River winds its way southward to meet the salt water in the Atlantic Ocean. The transition zone, known as the Delaware Estuary, is a vital resource for the region's 5 million people, who rely on the channel for drinking water, food production, shipping, recreation and power. The estuary is also an essential habitat for fish and wildlife. More

GIS myth: Getting current job data on a map is too difficult
The American Surveyor    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Now that one-third of the GIS System has been built, it is now time to implement the rest of the system, the Mapping Engine and the Linkage. Building the Mapping Engine is going to take some exploration on the part is the GIS System developer, as the developer will have to search all available data sources and collect different data sets that will "Fill in the Picture" of the mapping interface.

In the eye of the storm

Owen Kelly of NASA's Goddard Space Flight Center in Greenbelt, Md., created a 3-D image of Hurricane Sandy on Oct. 28 from data acquired by NASA's TRMM (Tropical Rainfall Measuring Mission) satellite ... one that can measure rainfall rates and cloud heights in tropical cyclones. Hurricane Sandy's eyewall appeared somewhat compact with its 40 km (24.8 miles) diameter. More

Good news and plenty of it
GPS World    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Firing on all cylinders — to use a slightly outmoded technological metaphor — GNSS moved forward on virtually every front in the past month. GPS made major advances both on the ground and in space, Galileo took a giant step, Compass continued on its roll, GLONASS has good news pending, and GAGAN is settling into space. But the best news of all is a very quiet, indeed somewhat hidden item. More

UK revokes key GNSS patent that sparked dispute over cooperation, interoperability
Inside GNSS    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Legal filings suggest the U.S and the United Kingdom may be well on their way to working through a heated dispute over patents that, if left unresolved, could scuttle efforts to make GPS and Galileo interoperable. The patents came to light last year when a British firm began seeking royalties from companies in North America and Europe making receivers that would use the upcoming L1 GPS signal and E1 Galileo signal.

A firefighter on Sept. 11, 2001, on his way to save people at Ground Zero, doesn't know where the ground floor exits, fire risers and sprinkler control rooms are located. A geotechnician wishes to publicly publish the terrain drawings and models he owns to help future generations. An architectural librarian laments that there should be simpler ways for authors to make their works accessible. More
