software works well with a GPS as an aid to mapping with OCAD. A registered
version is needed to be able to use it with a GPS. A CE Version is also
available which will work with a Palm Computer. Using this an active version
of the map could be used adding waypoints as you go and seeing your location
at all times A full version would still be needed to set up the map on a
normal computer. A summary of the steps involved in using a GPS and OziExplorer in association with a normal computer are as follows:
- Produce a bmp or gif version of your draft map
in OCAD. (file..export..gif or bmp Both formats are available in OCAD 9
& 10 only
bmp in OCAD 7)
- Use the above to produce a new map file in
- Your map then needs to be calibrated
with at least 6 known points reasonably spread across the map. up to 9 can
be entered). Given a perfect map theoretically only two points are needed.
The addition of more points allows for rotation and skewing of the mapped
image. The exact latitude and longitude of these locations needs to be
copied from your GPS using the calibrate function within Oziexplorer. New
Hint: Once you have copied two points save the result and then load the
rest of your waypoints. Then use the check calibration function in the file
menu. This way you can add any additional points you want to use for
calibration directly from the waypoint list. (Look out for the small button
for doing this!)
- Waypoints you then collect in the field can
be uploaded from your GPS, saved as a file and then loaded directly into the
Ozieexplorer map file you have produced.
- Within OziExplorer choose save map to image
file. This produces a bitmap file which can then be loaded as a template
I have found this process very satisfactory using a
GPS. This unit is economical, rugged and compact. Accuracy to within 4m is
possible in ideal conditions and up to 500 waypoints can be stored. A wide
range of makes and models are available on the market. It is obviously important
that the model you use has the capacity to upload and download data.
Using Garmin USB GPS units with OziExplorer
a) Using the
moving map feature with Vista & Windows 7 can be a bit tricky. This is
mainly due to the Spanner Software (works fine with XP), which emulates a com
port & is available from
Garmin will not install on these operating systems. However this now seems to
have been overcome, at least with Windows 7, by doing the following:
With your GPS
- Ensure you have the latest Garmin drivers installed
on your GPS.
- Set your GPS to Spanner Mode in settings. This
has the added advantage of ensuring you can see what is happening on your
GPS which does not happen on any of the other settings.
- Set Baud Rate on GPS to 4800
In OziExplorer (for more details go to http://www.oziexplorer3.com/support/oziexplorer/gps/ozi_gps_garmin.html
- Make sure you have at least Version 3.95.4s or later
- In OziExplorer Configuration /
GPS Tab, select GPS Make = Garmin; GPS Model = Colorado
The above settings
also work with the latest version of Google Earth.
b)To update &
GPS must be attached to your computer as a USB mass storage device (USB
Mass Storage Mode) and it will become visible as a disk drive.
