Hello im not a surveyor but I did obtain old field notes from the surveyor who did this property in 1983. im just unsure of what these numbers are . it says base station and then sobers that I don't know of. are these coordinates written in a certain form or is this a arithmetic check or something.are these numbers I can type into a mapping software or something? ?ÿThanks tom wuesthoff

Those are field notes from an instrument and 200' tape survey of 383 Dover Road (Route 513) from March 29, 1983. They might be useful to a professional surveyor that you hire to retrace the boundaries. In 1987-88 I worked 4 miles SW of that parcel near the corner of Route 513 and Route 24, but the firm I worked for would have been using an EDM by that date. I could ask a surveyor I know from that firm if he recognizes the initials as field crew members from other firms. We were just talking yesterday about another survey firm from that same area. If you care to engage him I might even show up to help him survey.

Nah, pretty sure BS means backsight is this instance as this is years before commercial GPS use.

As far as recreating the map from this data I think it's quite possible.

At the top of page 2 it looks like they set a couple points, DS 1 and DS 2.?ÿ They put the instrument on DS 1, sighted DS 2 and listed 0 degrees, 0 minutes as the angle which would make this line the basis of bearing for the project.

They shot some things and used the format:

object name, angle right in degrees and minutes, the distance from the instrument to the object (measured twice to average?), and ending with an elevation above an assumed benchmark of 100' shown in the upper right of the page.

It looks like they set a third point, DS 6.?ÿ Moved the instrument onto DS 6, backsighted DS 1 and shot some more things, including IP 10 (iron pipe, possible property corner?), and apparently set point DS 13.?ÿ Moved instrument to IP 10, backsighted DS 6 and shot some more things.?ÿ Moved instrument to DS 13, backsighted DS 6 and shot the rest.

I'm assuming they measured slope distances and recorded elevations so they could calculate the horizontal distances.

This is almost 40 years before my time so I could be off with some of these things. ?????ÿ

That format is very familiar to me.?ÿ

This means:?ÿ Transit at Point 13, Back Sighting Point 6

?ÿBStrand is not quite right.

Angle right is assumed, but more common than angle left.

The distances were slope measured with a 200' tape (very likely a ribbon chain) using taping pins, then reduced using the vertical angle in the right most column. There is no +/- to the vertical angle because they did not care about elevation just the cosine of the angle to get length. "100" would be the Page Number in that field book.

Distance?ÿ to point 2 (199.39' + 34.02') * Cos 1?ø05' = 233.37'

Points 7, 8 & 9 appear to be house corners shot clockwise

Looking at Google streetview of that house, no changes have been made to the front since 1983

The Google view of 383 Dover Chester Road, Randolph, NJ would puts point 1 near the SE rear corner. Rear monumentation was assumed to be less disturbed than pins along a road

OK sketch, should have more notes and a North arrow and/or a compass bearing from 1 to 2, did not record temperature or weather, some notes appear unreadable.

Computed distances and circled setbacks on sketch were done by a different person in the office than in the field, whose initials or signature should have been at the bottom right of the page. Anything I ever wrote in a fieldbook in the office was in red.

With the Tax Map I could make sense of the field notes.

Mr. Wuesthoff, you have asked a number of survey-related questions over the past year.?ÿ Are you simply curious about how surveyors do what they do??ÿ Or, are you trying to do your own surveying on property you own?

A quick search on the county website indicates that the Wuesthoff's are adjoiners to house #383...it is amazing how much information is on a field book page, when done correctly.

With a calculator and basic coordinate geometry you could make an autoCAD drawing out of theses notes, but you would essentially have to covert the angles and distances from polar to cartesian coordinates so you could plot them.

Easy-Peasy. Have fun!

Hi everyone . I live in the house next door and Iƒ??ve been hunting for property corners and doing research for about 3 years now . Itƒ??s interesting to me to find the the corner markers and fun at the same time. I just got a magnetic locator and Iƒ??ve found a lot of corner makers . Some are laying down in the ground and some are old pipes that are still set but crumbling if that makes sense .

Absolutely it makes sense. In some soils those pipe last only a few years. Also, it is quite common to find no more than 10%-20% of the monuments that were set at one time, even after exhaustive searches. On my personal 4 cornered home lot I have found only one corner monument in the 26 years I've lived here. I've searched up and down the street and found only 2 others!

I'm disappointed in all these guys lol, I'm a true Surveyor and those are Azimuths for each BackSight point, he only used Degrees and Minutes because that was acceptable then.

I think I found the iron bar they said they set in my deeds but its not a bar its like an angle iron or something . but its right on the mark .?ÿ

Frequently landowners will add something near our monuments that they feel are superior to what we have set.?ÿ This can be very confusing.?ÿ Several times I have encountered a 2" iron pipe sticking up a foot or up to three feet high that has been placed over the iron bar set by the surveyor.?ÿ In one case we had set 1/2" iron bars and the client later added one inch bars next to them, which were eventually driven down to allow easier mowing/trimming of the yard.?ÿ In the process the one inch bars were left closer to the ground while the bars we had set were driven an inch or two lower, but still there.?ÿ Finding an angle iron is not uncommon.

I've seen where a landowner added his own stakes. He put axles on the corners. The flange was up. You had to pull the axles, to find the rebar.?ÿ

And, they put some along the line too. Surveyor had flagged the line. It was easy to find a "line axle", and assume it was the corner.?ÿ

The math matters. When multiple markers exist, for various reasons.?ÿ

Do you get a survey when you purchase a house in NJ?
