- Introducing grid features
MobileMapper Pro's Grid Mapping Utility is an easy way to
log GPS positions and GIS data at waypoints arranged in
an evenly spaced grid. This allows you to gather measure-
ments made by field sensors in an organized fashion with
an easy-to-use navigation feature.
.
Grid parameters (see screen example opposite):
Number of columns and rows: The grid points in a grid
feature are arranged like cells in a spreadsheet. Imag-
ine standing in the left-most cell at the bottom of a
giant spreadsheet lain on the ground. As you look
toward the A1 cell, the columns appear on your right
and all the rows are in front of you. You can set the
number of columns and rows both in the field and in
the office with MobileMapper Pro's Feature Library
Editor (see the User Manual).
Heading: The heading of a grid feature is the direction
you are facing when you look at the "A1 cell." The
default heading is 0º (due North). If you want the grid
oriented in any other direction, e.g., to make it better
conform to the geography, just type in the compass
direction that you want to face when standing with the
grid in front of you and to the right.
Grid Point Spacing: The default value for grid spacing
parameter is 50 meters (or feet). You can set this
spacing to any number of meters you would like or
simply use the spacing that was set up in the office
with the Feature Library Editor.
- Recording an observation or measurement
When you select a grid feature from the feature selection
screen, the receiver starts logging a grid point.
