Thales Navigation Mobile Mapper - Manual (Page 26)

Each grid waypoint is a geographic coordinate you
should make every effort to occupy so that the data
you record is evenly spaced and complete. However,
each grid waypoint is merely an aid for navigating to
the ideal location for an observation or measurement.
All the data you record is ascribed to the position of
the MobileMapper receiver and NOT to the grid way-
point. If you cannot physically occupy this waypoint,
but can make the necessary visual observation, you
should do so and record an offset estimating the dis-
tance and bearing to the grid waypoint. If you are
recording measurements made by an instrument, you
should NOT record an offset but rather try to make a
recording as close as possible to the position.
- When you have occupied as many of the grid way-
points as you can and recorded the necessary obser-
vations and measurements at each, highlight the
Close
field at the bottom of the Logging screen and press
ENTER. This closes the grid feature and returns you
to the New Feature selection screen where you may
either log data to another feature, even to another
grid, or close the entire job.
10.Changing the Parameters of a Grid Network Before
Logging GIS Data
When you navigate to the location of the grid, you may
decide to readjust the size and orientation of the grid
based on field observations that you did not foresee back
in the office. For example, you may find that navigating
to waypoints with an east-west orientation is not feasible
if the area of interest is situated on a narrow strip of land
between two north-south running streams.
When you change the definition of a grid, MobileMapper
always assumes that you are standing in the corner of the
grid from which you can see the grid extend in front of
you and to the right.
