A survey’s legend is typically presented on the right hand side of the survey, or along the bottom of the document. If utm ticks are shown on a usgs topographic map, the zone is indicated in the credit legend in the lower left corner of the map collar.

How to read a survey map coordinates. If you are resurveying the land at the time of transfer, you may find a map on file with the local governing authority, or the homeowner may have a copy. Survey plats can also be read in reverse. How to read coordinates on a survey map we�re all familiar with the maps.
The distance is 1540’ to that point. Measuring distance is a key map reading tool to see how far you�ve travelled or how far your planned route takes you. Identifies existence of an easement and provides its location on the survey plan.
A beginner�s guide to measuring distance on a map. If utm ticks are shown on a usgs topographic map, the zone is indicated in the credit legend in the lower left corner of the map collar. I have a surveyor’s map of my land that does not have standard gps coordinates for the location of the survey markers (which i understand is pretty standard).
Read the compass degree system by starting with a specific point on the compass (north, east, south or west), and then reading the number of the degrees to the next point on the compass. How to read a land survey map. Within each zone, coordinates are measured as northings and eastings in meters.
Grid references are easy if you can remember that you always have to go along the corridor before you go up the stairs. For all quadrants, to convert quadrantal angle to true. After converting the compass degree headings to cartesian degrees, we convert them to radians and use basic trigonometry to convert the angle and distance into distances in x and y.
Starting at the upper left corner and working clockwise. Learn how to easily measure distance with our quick and simple guide. A map’s scale connects the.
Look at where your latitude and longitude lines intersect the coordinate lines on the edge of the map, and estimate the coordinates by their position relative to the closest graticules. They are given as coordinates, made from horizontal lines, with the equator referring to 0 latitude, and vertical lines, with the line passing through the prime meridian referring to 0 longitude. It all depends on which direction you are facing when following the line.
While a written description of a piece of land is useful — and in fact, necessary — in a survey, a map serves an important purpose. A line showing it travels n 15° 30′ 45″ e can also be described as traveling s 15° 30′ 45″ w. An example heading might be n63e.
This reads north, 63 degrees east. It is easy to find a particular place using a grid reference. Instead, my only way of locating all my survey markers is to follow what i believe is the surveyor’s indication of the bearing and distance from one marker to the next in line.
Knowing this, it is probably easier to decipher the code below. For the sw quadrant, add the quadrantal angle to 180, ie 269°17�49, very slightly south of due west. Os maps use a grid system that divides the country into squares of 100km x 100km, with each square having a two letter reference.the reference for the new forest area is su and these letters prefix the numeric grid.
Your survey will display information based on a scale. Qocmike is correct, the numbers are bearings and distances from 1 corner to the next. Many surveys start out with a series of letters and numbers denoting how to find the parcel and what its boundaries are.
If your map shows seconds, find the second closest to where each line intersects the latitude or longitude scale at the edge of the map. A survey’s legend is typically presented on the right hand side of the survey, or along the bottom of the document. Obviously the map has 4 points.
The northing values are measured from zero at the equator in a northerly direction. If playback doesn�t begin shortly, try restarting your device.
