Line and Station setup
For the basic and advanced modes, you will need to enter into the ENVI-MAG the
information about your survey grid. This includes:
▲ your starting points on each line,
▲ how far apart each line is,
▲ how far apart each station on the survey line is.
In considering the co-ordinate system shorthand you will be using for a survey
grid, you need to know that the units of measure are not important, as no
calculations are made with respect to distance. Consequently, you can use single
digits to represent values that may actually be in hundreds. Please also refer to
“Laying out the grid” on page B3-1 for more details on survey grids.
To show you the steps required to set the line station values, the following
example will:
▲ set the Line Number (LN) to Line 16 East (sometimes marked as
16+00E) with a Line separation (
SEP) of 2,
▲ set the Station Number (ST) to 50 North (sometimes marked as
50+00N), with a Station separation (
SEP) of minus 10. The minus
indicates that the walking direction is to the south.
From either main operating display, proceed as follows:
ST: sss.s d
SEP: pppp.p
LN: llll.l d
SEP: pppp.p
BATT:bbb
