Most surveys were done true with references from known sites.  Adjusted 
magnetic bearing were used for sanity checks.  Using actual magnetic 
bearings is a an ersatz method.


You can derive an excellent true North off of polaris if you have decent 
sidereal time.  It wobbles in the sky by about 1 degree but you can use 
polaris tables to remove the wobble.  That will give you really really good 
true north and a decent latitude.

Much better than attempting a magnetic compass measurements.  They are 
thrown off by all kinds of local variations.

It has to be true, because the declination in this area is about 16
degrees. The difference between the two results I found is a little less
than one degree.

This is actually for an easement, and it's open on both ends. It does 
start at the corner of a quarter section, but from there it's just a 
zig-zag line. Internal coordinates are unknown.


To make it more complicated, the original coordinates are based on the 
"California Coordinate System, zone III", which was derived using NAD27. 
So I had to convert those CCS-zone III, to NAD27 (lat/lon), then to NAD83

use with GE.


I did convert the first vector, and it appears to be off by about 12'.

I suppose the drift in the declination could account for the approximate 
0.9° difference. It has been ~~ 46 years since the original survey. 
However, if it was corrected for true back then, shouldn't true still be 
in the same place?

Yah. The old coordinate system is throwing me for a loop. The angle is
"supposed to be" ~~ 8.3° east. However, the quarter section corners are
well known, and the actual angle from the SE corner to the NE corner
comes to ~~ 7.4° east. However, the easement description says 8.3°
(along the boundary). So I just faithfully followed the angle called out
in the easement description, and ended up 12 feet east of the actual
boundary line. It can't be there, because that's not even on the same
quarter section.

What do surveyors do in a case like this? All the internal angles are
going to end up off by about 1° too (or are they?). Crazyness.

The road built on the easement has been in place for almost 50 years. A
sane person would re-pin all the corners of the easement along the
centerline of the road, and move on, because the description of the
road/easement do not match. The errors I see between what's described in
the survey documents and what is on the ground vary by between 30 and 60
feet.

I'm sure part of it is because the terrain is extremely tough. Slopes of
100%, and lots of trees. I have no clue how they did the original survey
in 1970. Today, you can GPS almost any point you want/need.

You have to use physical monuments and the DMS lines of the metes and

I just  go through and convert all the angles to Cartesian angles first

The easement starts at the eastern boundary of the quarter section
(which is not true north south; a little over 8° east). According to the
description it is supposed to be on that line at a certain distance from
the corner.

When I drew it on GE, I just measured that distance on that line, and it
actually comes out 35' north of where the road actually got laid. No big
deal, the easement is 60' wide, so it mostly fits.

However, when I used this tool to get a lat/lon, the point is about 12'
to the east of the point I measured. Now I know that drawing something
like this in GE is somewhat error prone, but I did not expect it to be
this far off.

To make it more complicated, the original coordinates are based on the

There are a number of factors in play here. Being a mapping guy and having a 
brother who is a land surveyor I probably know more about this stuff that I 
should :-)

One the angles called out make sure they are referencing True North or 
Magnetic. If it is magnetic then you need to look up the date when the original 
survey was done and use the magnetic declination for that time period since it 
does fluctuate from day to day. It's not much of a change normally but when you 
are talking about survey data and you are trying to close a polygon/property 
boundary those little differences make a hug difference if you are running a 
long line. The other end can be way off. 

Converting different coordinate systems can introduce just as many errors as 
well. A few inches difference here or there can move boundaries or make a 
property description not close as a complete polygon.

Drawing on Google Earth is doing so in a weird coordinate system. Typically it 
is Mercator projection so that will cause the polygon to look different than it 
would when in a coordinate system such as state plane.

Depending on the original coordinate system used the points may be called out 
in northing and easting which is based on a grid normally stated such as the 
California state plane and whatever region.

Surveyors do not always reference surveys in any stated reference system, they 
can use their own system of grid markings and callouts. When they do this it 
will always be based on a physical land marker such as a pip or other type of 
monument. Their deed descriptions are based on that and do not necessarily tie 
in to latitude and longitude. So whoever may have given you that written 
description may have introduced additional error when they converted to lat and 
long. 

Surveyors will use a transit and rod/prism system back before the days of GPS, 
and even farther back they might even use a tape measure and compass. These 
days they can buy extremely expensive sub centimeter accuracy GPS equipment and 
tie their survey in to state plane or latitude and longitude. They also have 
ways to post process the GPS data from the field for the date and time they 
were measuring to a system of GPS correction files based on HARN GPS monitoring 
stations.

As has been suggested you might want to look at QGIS and I believe there is a 
plugin available to type in meets and bounds descriptions to create the 
polygon. That then can usually be exported to Google Earth easily.

Yah. The old coordinate system is throwing me for a loop. The angle is 
"supposed to be" ~~ 8.3° east. However, the quarter section corners are well 
known, and the actual angle from the SE corner to the NE corner comes to ~~ 
7.4° east. However, the easement description says 8.3° (along the boundary). So 
I just faithfully followed the angle called out in the easement description, 
and ended up 12 feet east of the actual boundary line. It can't be there, 
because that's not even on the same quarter section.

What do surveyors do in a case like this? All the internal angles are going to 
end up off by about 1° too (or are they?). Crazyness.

The road built on the easement has been in place for almost 50 years. A sane 
person would re-pin all the corners of the easement along the centerline of the 
road, and move on, because the description of the road/easement do not match. 
The errors I see between what's described in the survey documents and what is 
on the ground vary by between 30 and 60 feet.

I'm sure part of it is because the terrain is extremely tough. Slopes of 100%, 
and lots of trees. I have no clue how they did the original survey in 1970. 
Today, you can GPS almost any point you want/need.

The easement starts at the eastern boundary of the quarter section
(which is not true north south; a little over 8° east). According to the
description it is supposed to be on that line at a certain distance from
the corner.

When I drew it on GE, I just measured that distance on that line, and it
actually comes out 35' north of where the road actually got laid. No big
deal, the easement is 60' wide, so it mostly fits.

However, when I used this tool to get a lat/lon, the point is about 12'
to the east of the point I measured. Now I know that drawing something
like this in GE is somewhat error prone, but I did not expect it to be
this far off.

To make it more complicated, the original coordinates are based on the

I did it, don't recall how, perhaps I used some kind of app but in the 
end, it was easy.  I may have just drawn a line and then reverse 
engineered the KMZ or KML file.

Subject: [AFMUG] Converting vectors to a shape (.SHP) file?


I have a boundary between parcels that is described as a series of
vectors (distance & bearing) from one point. Apparently this can be
imported into Google earth as a shape file (.SHP extension). I have been
looking for, but not finding a tool that allows me to enter the vectors
in text, and spit out the .SHP file. Does anyone know where I might find
this?

That looks like the simplest way to go.  Just getting the coordinates 
for 10 points is simpler than trying to crunch them into a DXF or SHP file.

Once you have all the GPS points it's easy to create a KMZ file with the shape.

The vectors describe a property line, and start at a fixed WGS84 coordinate.
Then it's a series of distances and azimuths from there. I tried drawing
them with GE, but there is an accumulation of small errors. There are about
10 vectors total.

Something like starting at point lat/lon, go 700 feet azimuth 8° 27' 42",
then 200 feet azimuth 27° 15' 08", and so on.

No idea exactly how to do this but you might want to try 
http://www.qgis.org/en/site/ 

Very cool and can probably do what you want.
