SCGS has created two
custom databases for use in Garmin personal navigation
receivers.
By loading one of these files on
your receiver you will be able to navigate to the control point
of your choice using all the navigation features of your
particular model.
If you are interested in the nearest
control points, the receiver will display the nearest 50 points
once you have selected the Customized Points of Interest file.
You may also spell out the control
point name.
A complete spelling is not required
but the search time will decrease with a more complete spelling.
The files are in a
special Garmin format for use as Customized Points of Interest.
You must have an SD Card of
sufficient size to hold the data base.
SCGS is using a 2GB card.
The file containing all the control
in South Carolina is approximately 800Mbytes.
.
On the Garmin 360, the
Customized Points of Interest menu will be displayed in the
“Where To” then select “my Locations” then the “Custom POIs”
menu.
On the Garmin 200 you must locate
the “Extra Points” menu.
SCGS has tested these files on its Garmin 200
and 360 units successfully.
The first file "Stations.csv"
contains all the survey control for South Carolina. There are
approximately 22,500 points in this database.
This dataset contains control points
whether or not the latest description indicates that mark may
have been destroyed.
This data set is most useful in
counties that do not have a significant number of GPS control
points
The second file "GPScontrol.csv"
contains only control points that were described as “GPSable”
the last time they were recovered.
This database contains approximately
7500 control points and is the most reliable as far as quality
and usability are concerned.
There may be some points in this
database that were not successfully recovered the last time they
were searched for.
In order to load either of these files on your
Garmin receiver you will need to download free software from the
following Garmin site.

The instructions on its use are
self-explanatory.
Caution, should you decide to delete this in
the future, you will lose your “Favorites” as well.
