Thank You...
With no end in sight, companies are trying to make it through these difficult economic times by having to ask more from their employees. What that means to the small business owner/operator is that they are doing more themselves. So, less time for everyone. Now you add in that the holidays are among us, and it’s a wonder that anyone has any spare time at all.
With that being said, I would like to take this opportunity to thank all those that have dedicated their precious time to help make our Chapter run smoothly and grow as it has. Every one from the Current and Past officers, the committee members to the countless volunteers that work at improving our profession. Thank you again for your time and hard work. This organization would not work if it wasn’t for you.

National News Rules of the Game: Implied Easements Part 1 One major area of liability that surveyors face is the failure to identify and locate easements burdening or benefiting the property being surveyed.
It’s a Requirement The identification and location of easements is often part of the surveyor’s responsibilities. For example, Massachusetts 250 CMR Section 6. 01 (1)(a)(1) requires surveyors to “obtain copies of recorded documents affecting the survey.” Section 6.04 (1)(c)(1) is even more explicit; it requires surveyors to “reconnoiter the area, recover existing monumentation and note all physical evidence and encroachments affecting the site.”
Another example is in the 2011 Minimum Standard Detail Requirements for ALTA/ACSM Land Title Surveys that requires the surveyor be given “any record easements benefiting the property.”1 The surveyor is further required to disclose “the evidence, location and extent of potentially encroaching structural appurtenances and projections observed in the process of conducting the survey … by or onto … rights of way, [and] easements … disclosed in Record Documents provided to the surveyor.”2
The surveyor is required to show “evidence of any easements or servitudes burdening the surveyed property,
This is the second of three articles discussing the precision obtainable with the Online Positioning User Service (OPUS) offered by NOAA's National Geodetic Survey (NGS). The first article appeared in the immediately preceding issue of this magazine. OPUS is a Web-based utility available at www.geodesy.noaa.gov/OPUS to which surveyors and others can submit a dual frequency GPS data set and quickly receive an email containing positional coordinates for the location where their data were collected. OPUS computes these coordinates by processing the submitted data together with GPS data from the U.S. Continuously Operating Reference Station (CORS) network and/or the International GNSS Service (IGS) network. Actually, there are two OPUS processing engines. One engine is called OPUS-S, where "S" stands for static, which is designed for use with GPS data spanning more than two hours. The second engine is called OPUS-RS, where "RS" stands for rapid static, which is designed for use with GPS data spanning between 15 minutes and two hours.
In the first article, it was stated that the precision of coordinates computed with OPUS-S depends primarily on only one variable--the duration of the observing session. On the other hand, the precision of coordinates computed with OPUS-RS depends primarily on three variables: (1) the duration of the observing session, (2) the geometry of the CORS/IGS stations being used for the OPUS-RS solution (as measured by a quantity called IDOP), and (3) the distances from the user's GPS receiver (hereafter called the rover) to the various CORS/IGS stations being used for the OPUS-RS solution (as measured by a quantity called RMSD). OPUS-RS depends on network geometry and the distances from the rover to the CORS/IGS stations because it interpolates (or extrapolates) the atmospheric refraction values experienced at the CORS/IGS stations to estimate the corresponding values at the rover. As a result of the experiments described in the first article, NGS developed empirical formulas to estimate the standard deviations of OPUS-RS solutions as a function of both IDOP and RMSD. These formulas have the general form [see PDF for formula and mathematical symbols] where represents the standard deviation (for a particular dimension and a particular observing-session duration) and where , and are parameters whose values are estimated from several thousand OPUS-RS solutions. The values of , and vary depending on whether represents the standard deviation in a horizontal dimension or in ellipsoid height. Also, these values vary depending on the duration of the observing session.
Using these formulas, NGS then created maps that illustrate expected OPUS-RS standard deviations as a function of the geographic location of the rover. Figure 1 illustrates such a map for the case of the vertical standard deviation obtainable with 15 minutes of observed data. NGS has developed an interactive Web-tool residing at www.geodesy.noaa.gov/OPUSI/Plots/Gmap/OPUSRS_sigmap.shtml which presents similar maps, some illustrating horizontal standard deviations and others illustrating vertical standard deviations, some for 15-minute

The Puzzle: Five surveyors worked in a growing town. One was employed with the city while the other four worked for private companies. You could always tell who had surveyed a property because each surveyor preferred to use a different color of ribbon on his stakes and also used different monuments.
Determine where each surveyor was employed, which size & type of monument he used and his ribbon preference.
Clues: 1. Charlie, who didn’t work for the City, didn’t use pipes. The Survey Solutions surveyor didn’t use the ½-inch monument. Bob, who didn’t work for Rocket Land Surveying, used rebar, but not the 1-inch size.
2. Ed, who didn’t use rebar, used a larger monument than the surveyor who used blue ribbon.
3. The two ¾-inch size monuments were a pipe and the monument set by Blue Moon Surveying. Archie from Survey Solutions didn’t use rebar. Doug used a ¾-inch monument, but it wasn’t a pipe.
4. One of the surveyors who used rebar also used green ribbon. The City surveyor used rebar.
5. The two surveyors who used pipe were the one who also used orange ribbon and the Zodiac Engineering surveyor. One surveyor’s rebar was the ½-inch size.
6. The surveyor who used pink ribbon also used rebar, but not the ½-inch size. The square bar wasn’t set by the surveyor who used yellow ribbon.

observing sessions and others for one-hour observing sessions. With this tool users may specify a geographic location, whereby this tool will display the numerical value of the standard deviation in each dimension which may be expected with OPUS-RS for GPS data collected at that location. Because the contents of these maps depend highly on the number of available CORS/IGS stations and their geographic distribution, NGS updates the maps on this Web page on a weekly basis to keep pace with the rapid growth of the CORS/IGS network.
In yet another experiment, NGS researchers conducted a head-to-head comparison by processing each of several data sets with both OPUS-S and OPUS-RS, comparing both solutions to coordinates previously published by NGS. Both one-hour data sets and two-hour data sets were processed. OPUS-RS was the clear winner for one-hour data sets, primarily because OPUS-S could not reliably resolve the associated integer ambiguities. For two-hour data sets, the OPUS-RS results were only marginally more precise than the corresponding OPUS-S results, with a few exceptions when OPUS-S yielded slightly more precise results.
As a result of all the experiments, NGS recommends that users utilize OPUS-RS for observing sessions between 15 minutes and two hours and utilize OPUS-S for observing sessions longer than two hours. Actually, NGS is planning to revise the code for the OPUS web page so that data submissions will be directed automatically to either OPUS-S or OPUS-RS in accordance with this recommendation.

Rules of the Game: Implied Easements Part 1, cont. from page 3 disclosed in the Record Documents provided to the surveyor and observed in the process of conducting the survey…” along with “evidence of easements or servitudes not disclosed in the Record Documents provided to the surveyor, but observed in the process of conducting the survey…."3
On the plan the surveyor is required to show easements, rights of way, and servitudes disclosed by the record documents.4 The optional survey responsibilities and specifications in Table A allow the client to contract with the surveyor to “locate improvements within any offsite easements or servitudes benefitting the surveyed property that are disclosed in the Record Documents provided to the surveyor and that are observed in the process of conducting the survey….”5
The difficulty arises for the surveyor when there are easements reflected in the records, but the easements are not created and conveyed by a deed.
Subdivision Easements One source of an easement that arises by implication is an easement created by the description of a lot that references a subdivision plan. As a general rule, where 1) the deed conveys a lot in a subdivision, 2) the deed refers to the subdivision plan, and 3) the developer-grantor has title to the road, then the lot being conveyed receives a private, appurtenant easement in streets, alleys, and open areas shown on the plan.6 The easement created does not depend on whether the plat is recorded or the roads are dedicated for public use. The creation of an easement that is appurtenant to the lot caused by the mere reference of the plan in the deed gives rise to an easement by implication under the equitable doctrine of estoppel (a legal principle that bars a party from denying or alleging a certain fact owing to that party’s previous conduct, allegation, or denial).
