CoGo

Most CoGo (Coordinate Geometry) functions in J-Field are 

rather self-explanatory after viewing their diagrams.  

CoGo 

Direct

,

 Inverse

,

 Shift

 and 

Rotate

 are found in the 

Basic

 group 

of CoGo functions that will be explained here.  

CoGo Basic

 Functions

In all CoGo function diagrams, labels shown in black are 

inputs and labels shown in red are the resultant calculations.  

Input points are displayed in green and red points are 

resultant points created from the function. 

Direct

CoGo Direct

Direct calculates the coordinate of a new point (

P

2

) given 

the coordinate of a known point (

P

1

), bearing (

B

) and 

distance (

D

) from 

P

1

.

Notice the vertical line in the white box shown between 

H,Abs 

and the input “0.0 ft”:

Clicking on the left side of this white box with 

H, Abs

 will 

toggle it to the other options of 

H, Slope

 and 

ΔH

 

Clicking on the right side of this box will allow for the entry 

of the value.  This functionally is similar in all CoGo menus 

when you see a white box separated with a vertical line in 

the middle.

The resultant point is shown in the orange box.  Clicking on 

this box will allow you to edit the Name, Description and 

Code of this point.

Once all the inputs have been entered you may tap the 

diagram to preview the results in the map.  If satisfied, tap 

Create to create the resultant points.

Preview Screen of 

Cogo Direct

The 

CoGo Direct

 

function can be used to calculate and store 

an offset point by using the internal compass and camera to 

determine the offset bearing.  To determine the bearing to 

an object using the compass tap the 

 button in 

the bearing entry screen.  Align the cross-hair at the desired 

object and press the check hardware button to capture the 

azimuth and then tap 

Apply

.  Determine the offset distance 

to the desired object with a tape measure or laser distance 

meter.  

It is important to check and confirm the compass 

calibration is working properly before using this feature; 

recalibrate the compass when necessary.  Occasionally, the 

camera screen may go blank or cause a crash of the system 

when using this feature or other features of J-Field that 

use the camera.  This is a known problem with the current 

camera driver.  If this happens, reboot the unit.  Hold the 

On/Off button down to power off the system if becomes 

unresponsive.

  The accuracy of this offset method is limited 

by the accuracy of the compass (typ/- 2 degrees).  To 

determine a much more accurate position from offsets, use 

the 

CoGo Resection

 function.
