When changing from the default 50 meters, keep in mind
that the selected value will determine the density of mea-
surements. If this number is less than 5 meters or so,
there is no point in using a Grid feature. Simply walk
around and take samples by visually estimating the
required density. If you increase the spacing, be sure the
spacing supports the density of measurements you
require.
Uploading the Grid Feature to the Receiver
You upload grid features to the receiver by uploading the
feature library that contains it. You can either upload the fea-
ture library as a standalone library that the user in the field
can select to record a new job. Or you can use MobileMap-
per Office to import the feature library into a job created in
the office. Either way, you just have to click on
File>Upload to
GPS and select the file you want to use in the field.
If you want to inform the field user where to begin logging
the grid feature, just create a waypoint in MobileMapper Of-
fice by clicking on
Tools>Place Waypoints . Make sure you
change the name from the default “WPT001” to a name tell-
ing the user that this is the point of beginning for logging a
grid. Then upload this waypoint as described on page 71.
