Use Input Point From Next Row
 
Assume that a user loads a point file with 5 points (A-E), one point per row, each with Latitude and Longitude values into the grid. He has set up four columns (C1-C4). The user has selected to Output the ahead azimuth to C3 and the distance to C4. He has also selected “Use Input Point From Next Row”.
 
Point A in Row R1 (Latitude = column C1, Longitude = column C2)
Point B in Row R2 (Latitude = column C1, Longitude = column C2)
Point C in Row R3 (Latitude = column C1, Longitude = column C2)
Etc.
 
Upon hitting the Inverse button, the Calculator will compute the azimuth and distance between Point A (R1) and (R2) and write the results to the specified cells in R2.
 
Next, it will take R2 and R3 (i.e. the next row) and calculate the inverse values between them and write the results to the specified cells in R3. Remember: The results are written to the next row when “Use Input Point…” is selected. The output cells in R1 will be left blank.
