We provide tips, how to guide, provide online training, and also provide Excel solutions to your business problems. Why does Jesus turn to the Father to forgive in Luke 23:34? Converting Distance (Measured Depth), Dip (Inclination), Azimuth to 3D coordinates depends on how you interpret what is happening between the locations where measurements were taken (survey stations). An easy method to remember this is to recall the letters HV (High Voltage), which means that horizontal reading comes first, followed by vertical reading. I found that if there's a straight segment (I1 == I2 and A1 == A2), then B ends up 0 and so RF produces a divide by zero error. In these cells I will have the formulas to calculate the interpolated figures. Relative location, on the other hand, defines a location in terms of another. They differ from those in most math/physics references because in geography, the azimuth is usually taken east of north rather than north of east. How to convert/desurvey Directional Survey measurements into XYZM points? The relevant portions are: As Eric writes, you can easily end up with a div_by_zero error here: You can however avoid this without testing for exact zero: When abs(B) is less than about 1e-9, the tan(B/2) term will be exactly (within the 64/53-bit precision of a double) the inverse of 2/B. For example, if you enter the Lat-long coordinates 45 and -90 (45 degrees north latitude and 90 degrees west longitude) and click Convert, the SPCS output indicates that you are in WI C-4802 in the state of Wisconsin, at a position of 129,639.115 northings and 600,000 eastings, in meters.

UTM, UTMRF/MGRS, CH1903, Gauss-Krueger, GK, NAC, W3W and WGS as decimal, decimal minutes or in degrees, minutes and seconds. On a map, eastings appear as vertical lines. You may also find the coordinates of previously discovered locations. Therefore, an azimuth of 90 corresponds to a quarter of the way clockwise from 0 or 360, which is east. Similarly, 180 is south, and 270 is west. Draw an arrow pointing east (azimuth of 90) for an arbitrary borehole azimuth reference. Otherwise, you have to refer to the relative positions of A and B. Step 5. Comment, if you have further inquiries or have anything to add. (Try this with a string on a globe.) How to convert Distance, Azimuth, Dip to XYZ? =M7+O6. Thus the azimuth of due north is 0, due east is 90, due south is 180, and due west is 270. The shortest distance between two points on the surface of a sphere is an arc, not a line. 08-14-2014 12:19 PM. The fist is approximately equal to 10 degrees. Arrange the given bearing (i.e., Degrees, Minutes, Seconds) and distance readings in an organized manner in Excel Worksheet. By multiplying the zone number by 6 and subtracting 180, you may find the eastern limit of any UTM zone. Local values of magnetic declination should be stated in the well program to plus or minus 0.1O. f(E,N)=180-90*(1+SIGN(N))*(1-SIGN(E^2))-45*(2+SIGN(N))*SIGN(E)-180/PI()*SIGN(E*N)*ATAN((ABS(N)-ABS(E))/(ABS(N)+ABS(E))).The formula gives the bearing from 0 to 360 degrees for any value of E and N.E=E2-E1 and N=N2-N1.For E=N=0 the bearing is undefined. The closer the point is to the grid central meridian and to the equator, the smaller the correction. To subscribe to this RSS feed, copy and paste this URL into your RSS reader.
