Elevation Studies & 3-D Dipstick Topo Maps 

C-7 

Step 1 – Collecting the Outer Box 

You’ll  collect  the  first  box  that  bounds  the  exterior  perimeter,  36  ft  on  a  side.    Start  at  the  northwest  corner  in  the 
drawing  to  the  right  (marked  Box1  Start/End)  and  walk  the  Dipstick  south  until  you  reach  the  end  of  the  area  to  be 
measured.    As  you  do  this,  stop  every  4  ft  and  mark  a  circle  around  the  Dipstick  foot  that  is  4  ft  away  from  the  last 
marked location.  This will make the first Box go slow, but you’ll need these locations later.  When you reach the first 
corner of Box1, wait for the beep, then press the letter “C” on the keyboard of the Dipstick computer.  The Dipstick will 
“beep” at you to let you know it marked this corner.  This is not a new reading.  (The Dipstick can only make one sound, 
“beep” so don’t worry, this is not another step.)  Do not stop the data collection program.  Now turn the Dipstick and 
walk towards the east as shown above, until you reach the 2

nd

 corner of Box1.  Do not mark every 4 ft on this leg.  After 

you hear the beep when you reach the end, press the letter “C” again to mark this corner.  Then turn north and walk all 
the way to the 3

rd

 corner of Box1, again marking a circle around the Moon feet every 4 ft., and press the letter “C” again 

after you reach the corner.  Finally, walk the Dipstick back to the west until you reach the start/end point of Box1.  Press 
<Enter>  to  stop  collecting  data.    The  end  of  this  leg  is  exactly  the  same  point  where  you  started  from.    Do  not  mark 
every 4 ft on this leg.  This completes the first box – the outer black box – in the picture above.  You will have walked a 
big “box” and you will have marked the line every 4 ft on the west and east sides as shown in the picture above.   

 

Step 2 – Collecting the Inner Boxes 

Go 8 ft down (south) from the start point of the outer box, and set the back end of the Dipstick on the circle you marked 
there, with the start end of the Dipstick facing east across the outside Box.  Note: this is 8 ft down, not 4 ft down from 
the start point.  You will be at the start/end point of Box2.  Start a new run, and collect data from here all the way across 
to the other side of the large outer box.  When you reach the 1

st

 corner of Box2, press the letter “C” on the keyboard, 

then  turn  north  and  walk  4  steps  to  the  2

nd

  corner  of  Box2.    Again,  press  the  letter  “C”  here.    Then  turn the Dipstick 

toward  the  west  and  collect  data  all  the  way  back  across  until  you  reach  the  3

rd

  corner  of  Box2,  and  press  “C”  once 

more,  then  turn the Dipstick south and collect 4 more steps.  You will be at exactly the same point where you started 
Box2.  Press <Enter> to stop collecting data in Box2.  Pick up the Dipstick and walk 8 ft farther south (8 ft, not 4) then 
collect Box3 the same way.  Continue collecting data in boxes this way until your inner boxes fill the space inside the 
outer box as shown above.   

 

Step 3 - Editing the Data 

You can do this on the Dipstick computer or on your desktop or laptop computer.  Select the first (large, outer) box and 
use  EDIT/UNBOX.    If  you  have  pressed  the  letter  “C”  each  time  you  reached  a  corner,  the  computer  will  fill  in  the 
corner locations for you.  If you forgot to type  the  letter “C”  in the  corners, you can fill it in now.  When you press 
<Enter>, the computer will calculate and adjust for the bias on this box, and it will break the box into 4 legs.  What’s 
more, the 3

rd

 and 4

th

 legs will be reversed, so they will look as if they had been collected in the same direction as legs # 1 

and #2.  Now select Box1/A and use REPORT/DATA POINT LISTING to get the elevations of the points that are 4 ft 
apart on the first leg of the outer box.  Write down or print and circle the elevations of the start point, point number 4, 
point number 8, point number 12, point # 16, and so on.  You want the elevations of every 4

th

 point on leg Box1\A.   

 

Now open the Run Header for Box2, and type in the start point elevation for Box2.  The elevation of the start point of 
Box2 is the same as the elevation of point 8 on Box1\A.  Now use EDIT/UNBOX for Box2.   

 

Now open the Run Header for Box3, and type in the start point elevation for Box3.  The elevation of the start point of 
Box3 is the same as the elevation of point 16 on Box1\A.  Now use EDIT/UNBOX for Box3.   

 

Repeat this process for all the other Boxes.   

 

Step 4 - Making ASCII Elevation files 

At  the  Run  level,  highlight  Box1\A  and  use  REPORT/ELEVATIONS  (fle)  and  it  will  make  an  ASCII  Elevation  file 
from the Run you have highlighted, and it will store the new ASCII file inside the Job folder.  You can do this over and 
over for each of the runs in the project.   

 

Speed  Tip:

    Instead  of  making  the  ASCII  files  one-by-one,  go  to  the  Run  level  and  ensure  that  all  the  long  runs  are 

marked with the Run Flag “A”, and that no other Runs are marked with a Run Flag “A”.  You can mark or unmark Runs 
by  highlighting  them  in  the  RFCollect  program  and  using  EDIT/RUN  HEADER,  and  checking  (or  unchecking)  the 
ASTM E-1155 box.  After doing this, go up to the Surface Level and choose  

REPORT / MULTIPLE REPORTS

 

(BATCH) / ASCII ELEVATIONS (File).

 

This will 

instantly

 create and save ASCII Elevation files for 

all

 the Runs that were marked with the Run Flag “A”.  You 

will still need to make ASCII files manually for all the short 4-ft runs, since they cannot be marked with the checkmark 
for ASTM E-1155.  This completes the 4th step.
