A.  Creating a Geo-referenced Map

Software you will need includes:

1. Oziexplorer PC version
2. Oziexplorer Pocket PC version
3. Image2OZF.exe program (This software can be found at http://www.oziexplorer.com.)
4. ESRI Software
1. ArcGIS 9  OR  Arcview 3.2a and the Image-Tools extension. Call Will Patterson of ITB for information about this extension.

1. Make a new working directory on your PC.  You can give it any name, but be sure you have plenty of space on the drive.
2. Start a Map Document (Av3.2: Arcview project) with your shapefiles and images displayed as you like in your View. (Av3.2:Load the Image-Tools extension). Set the scale in the View to either 1:24,000 or 1:36,000 (higher scale = poorer image quality). In ArcMap make sure the your "Layer" datum is Albers, Nad 83(Right click on the Layer, Top item in table of contents and click properties)
   
3. Click File->Export Map and select JPEG for type. Click the arrow next to options and check the "Write World File" box. Adjust the Resolution and File name, destination as you like and click Save. (Av3.2: Under the Image-Tools menu, select "Export View" to Georeferenced JPEG Image. Name the JPG file and place it in your working directory.)
   

Part 2, describes the process of creating an image to use in the Oziexplorer software.

1. Creates a file with projection information. (*.map):

Start up Oziexplorer on your PC. Under the "File" menu select "Import Maps", then select "Single DRG Map" for a single map or select "All DRG Maps on CD" for multiple maps in the same direcotry. Both "Image File Path" and "Map File Path" should be set to the same working directory. Set the import parameters to Datum:Nad83 and Projection:Albers( not Lat/Lon).  If Teale Albers be sure to enter the -4000000 for false northing. Click "OK".

2. Converts your JPG images to an OZF image:

Start the Img2ozf.exe program. Set the "Source Image Folder" and the "Destination Folder" to your working directory. The "Temp File Folder" can be set to any directory with enough working space. Set "Image type" to 'ozf2". The Zoom levels will take some experimentation on your part. The more zoom levels you check the larger the image file. You may want to check all of these initially and then discover for yourself what zoom levels are appropriate for your scale of map and the size of the Ipaq screen. Selecting fewer zoom levels results in a smaller image, thus saving valuable storage space. Select the JPG images you created and select the "Process to Image Files to OZF files" button. This process may take a little while.

3. Transferring the maps to your Handheld:

On your Hnadheld make a directory on your flash card(CF or SD, CF recommended). Name it Maps. Load your *.OZF2 and *.MAP files off of your PC into MAPS directory directory.

4. Configure Oziexplorer to read your maps on the Handheld:

On your Handheld select the "File" menu, and scroll to "Configuration" then select "Map& Data Files".  Within the "Map File Paths" and the "Data File Path" window select \CF Card\Maps\. Save your changes.
Select "File" again and scroll to "Configuration", then select "Map Image Files". In the 'Map Image File Path 1" window type select \CF Card\Maps\. Save changes.

5. Configure Oziexplorer to recognize your Garmin 12xl NMEA string:

On your Ipaq select the "File" menu, and scroll to "Configuration", then select "NMEA (GPS)". Set the following parameters: "Baud" is "4800", "Sentence" is "GPRMC", "NMEA Datum" is "NAD27" (unless your imagery is in another Datum). Make checks in the following boxes: "Use Chk Sum", "Show GPS Fix Data", and "Show DGPS secs". Leave the other boxes unchecked. Hit "OK".

6. Configure your Garmin 12xl to be recognized by Oziexplorer:

Turn the Garmin on. Hit the "Page" button to the "Main Menu". Select the "Setup Menu", then select the "Interface" menu. The parameters should be set to the following: NMEA/NMEA, NMEA 0183 2.0, 4800 baud

7. View the maps in Oziexplorer and display your position:

Make sure your Garmin is properly hooked up to your Ipaq. Open Oziexplorer. Select the Folders icon at the bottom. If your maps don't show up at first, you may have to browse for them. Double click on your map of choice and if all goes well it should show up within your window. To display your position, select the little thunderbolt/GPS icon at the bottom. Your position will always be displayed at the center of the map, and north will always be toward the top of the display.

B. Using the Moving-map Display

1. Turn on the GPS unit to allow it to begin searching for satellites.
2. On the handheld unit, click the Start menu, and select OziExplorer.
3. From the File menu, select Open Map File.
4. From the list of maps displayed, select the appropriate map for use, then click "ok".
5. Click the "lightning" GPS button at the bottom of the screen.
6. Connect the GPS unit to the handheld with the appropriate cable.(note: this icon must be clicked OFF to change scale or move around on the map). 
7. As long as the Garmin is receiving signals the display will track you as you move around.

C. Troubleshooting

In the event that your moving map display does not seem to be functioning properly, try some of the following procedures

1. Be sure your GPS unit interface is set at NMEA/NMEA
2. Try a soft reboot of the handheld.
3. If the moving map point seems consistently incorrectly placed on the map, try changing the GPS datum from NAD 27 CONUS to NAD 83.
4. Make sure the cable is securely plugged in.
