G7TO INSTRUCTIONS UPDATE
21 Dec. 1998 #(Add UTM, CSV, and Datums Functions)

G7TO has once again been upgraded to keep up with "customer requests".
Now comes Version 304 which can down/upload data in a large
number of different datums, create comma separated value files, and
output/input data in the UTM format. Get the latest versions and stay
up to date at:

http://www.gpsinformation.org/ronh/g7towin.htm

G7TO304 is a (free) DOS program by Ron Henderson (crh@proaxis.com).
The program will download in one operation from the Garmin receivers,
waypoints, routes, proximity points, tracks, and symbols (if they exist)
to Street Atlas files in all the various ways Street Atlas can present
these data.

NOTE: Use .SA3, .SA4, .SA5, or.SA6 extenders depending on your version
of Street Atlas.

Consider that the following "tutorial" (single) command line:

g7to[w] -i g45wxtr -o combine.sa5 -a >combine.txt -q23 -p fy -p ayellow
-p s*h -r0wn -r tm -r cred -r s*h -rwn -t cblue -w x18,12 -d -u

With the optional Windows version [w], will input (-i) from the Garmin
receivers (g45) Waypoints (w), Proximity Waypoints (x), Tracks (t),
and Routes (r).

Then will Output this data (-o) to an SA3/4/5/6 file, COMBINE.SA5, and an
ASCII file (-a), COMBINE.TXT. The *.SA* file will show the Waypoints with
their names only (-q23); will Fill (-p fy) the Proximity Areas (a) with
Yellow (-p ayellow) 'highlighter'(-p s*h); show the Active Route 00 as the
SA4-type route without Routepoint names (-r0wn); show all other Routes
(1-19) as Medium Thickness (-r tm) RED Color (-r cred) *Highlighter line
Style (-r s*h) without Routepoint names (-rwn); show the Track Color as
BLUE
lines (-t cblue), and convert the Waypoint default square symbols (-w 18,)
to SA5 dots (12) instead of squares.

# In the COMBINE.TXT file, the Distances (-d) of tracks and routes will
be summed, and the location data listed in UTM (-u) coordinates.

The order of commands is not important. Refer to the documentation to
display MORE of the Garmin data than the above command line invokes.

NOTE: Route 00, which is displayed as an SA-type route, is the
FIRST route created in the G-III and not the "Active" Route as in
the other Garmin models...

G7TO will upload in one operation all the data in COMBINE.TXT to
the Garmins with:

"g7to[w] -o g45 -i combine.txt"

and retain the waypoint comment creation dates. (COMBINE.SA* files can
also be used, but the comment creation dates are lost.) All track
time-stamps are reset by Garmin receiver to 0 hms. G7TO converts any 0
hms time to PC time in the downloaded file.

NOTES: The symbols of the Garmin receivers aren't exactly duplicated by
the symbols available in SA, but the correspondence is "recognizable".
The first number after the first ";" in the "W" records is the Garmin
symbol, and the number after the second ";" is the "Style" of Garmin
display on the map page -all of which can be edited...

You have complete control as to how any SA line LOOKS... It can
be solid, or 'highlighter', and be any SA color or thickness.
Routepoints can have Route No., names, comments, or none.
Waypoints can have names with or without comments. SA4/5 Tracks
are now lines instead of dots; SA3 tracks remain dots.

GARMIN'S NEW PVT PROTOCOL

In order to activate the "PVT" data output, use the command:
g7to[w] -i g45g >pvt-name.txt
Type an 'x' or 'X' to stop the data transfer. See the .DOC file
for a list of data elements outputted.

SCREEN CAPTURE

To download any G-III or Street Pilot screen, use the command:
g7to[w] -o filename.bmp
NOTE: It will be necessary to rotate the SP image 90 Deg.

# DATUMS and CSV (Comma Separated Values)

Datums of the data outputted can be selected from the file, g7datums.txt.
An example would be: g7to -u -i g45wxpt -y nad27_canada >comb-dat.txt
The switch for datums is -y followed by the datum_word.

In order to output a CSV file of the data use the command:
g7to -i g45wrtx -o comb.csv -a >comb-csv.txt
Output files with a .csv extender will be CSV.

LARGE TRACK FILES

An added feature to this version of G7TO is the ability to convert
very large track .TXT files (up to 32,767 trackpoints) to an SA file...
Long
tracks can be made by adding several track.txt files together with the DOS
COPY command... (These can ALSO contain Waypoints and Routes)... The
command line for a "long_track" is:

g7to -i longtrk.txt -t cblue -o longtrk.sa5 -f 0
(The g7to default without (-f 0) is 4,096 trackpoints.)
(The g7tow default without (-f 0) is 65,535 trackpoints.)

OTHER PROGRAMS

In addition to the above, G7TO will read and write route files for
Navigate.exe. Navigate.exe uses the file name routes.clg to store
the route data. G7TO Version 3.02 also adds the capability to read
waypoint files exported from Lowrance's GDM16 and can write files
which can be imported into GDM16. The version of GDM16 must be 3.1 or
greater.

G7TO will output/input Navigate.exe routes.clg routes files;
GarDown7 raw format; and Garmin64 format. For input, GarDown7, and Garmin64

are all read as text files. If the input file is Garmin64 only the Track
and Waypoint records are processed.

Support for Fugawi exported waypoint file and saved track files
has been incorporated into g7to Version 3.02.23. The suffix for
Fugawi exported waypoint files should be .fwp. Fugawi uses .txt,
so the file should be renamed. When saving (not exporting)
Fugawi track files, the 'new track' information is saved. The
suffix used by Fugawi for saved track files is .trk and they can
be read directly by g7to, you do not have to rename the file. Fugawi
.trk files are binary and can not be edited in a normal text editor.

Support for OziExplorer exported Garmin Waypoint and Track files has
also been added. After exporting Ozi waypoints to a .txt file, rename
the text file to fname.owp. After exporting Ozi track points to a
.txt file rename the file to fname.otr. G7TO therefore allows one to
create waypoints or tracks with Fugawi and convert them to a format
that can be read by Ozi. The reverse is also true.
