Working Example 1

You need to complete a survey on a
small lake and wish to record the
depth of the lake that is measured by
a 3

party depth sounder at certain

locations. This depth sounder
constantly streams data at a rate of
1Hz and sends the depth it has
measured in the following format:

27.234
27.345
27.232

…..

The ASCII Input interface needs to
be configured such that when a
position is measured, the depth
measurement will be stored as
annotation 1 with that point. To do
this, in the CONFIGURE\ ASCII
Input panel, press ANNOT (F3) and
configure Annotation #1 to accept
the incoming ASCII data as shown
below.

Note that because the depth
sounder is streaming data, the depth
measurement that is stored with the
point will be the last measurement
received by the sensor before the
point is stored (the point can be
stored either by pressing STORE
(F1) or using Auto Store
functionality).

The co-ordinates of points can now
be measured over the lake and
additionally, the depth of the lake at
that point is also recorded as an
annotation.
