Steps to Convert an OziExplorer Format Map to Memory Map

Steps to Convert an OziExplorer Format Map to Memory Map

Main idea came from Prado point forum post at

Required items:


Setup the PC version of MemoryMap and license the ‘import’ feature on your PC.  (You are allowed to license two PCs, and you can move license later to a difference PC if you want via the memory-map web site)

To make the process easier for yourself, create a new directory and place a copy of the OziExplorer maps into that directory that you want to convert. If you have a “bunch” of maps, this is a good time to look at splitting the maps up into logical groups and placing different maps into different subdirectories.

DeMapper is used to convert the image in the OziExplorer map to a PNG format file.

There are only two buttons to click in DeMapper, Choose maps, and Decode Maps.

Select the OziExplorer files after clicking select maps, and then press Decode Maps.

The PNG files are placed into the same directory as the OziExplorer maps.

DRGMapCal232 provides the conversion of the calibration file. (That is, translates the ozi .map file into a .jpr file that Memory-Map can understand)

Note: Any Ozi Maps using datum GDA94 won’t convert in DRGMapCal. You will need to use the OziExplorer PC program to change the datum to WGS84 and re-save the .map file first.

If you have the free version, make sure you only have 5 or less map files in the directory you are about to work on.

There are a few more options in DRGMapCal, but the defaults are basically fine.

Select the Input directory where you have your Ozi maps from the DeMapper step. Click Browse to select it

Select the output directory where the converted calibration file will be written. Assuming you made a new directory for this exercise with just this map(s) which you are working on, then select this directory.

Make sure the “File Type” is selected at JPR

Click “Generate output files”


You should now have two extra a files in your directory, a PNG and a JPF file.  These now need to be imported in Memory Map.

Start Memory Map on the PC

From the menu

Map -> Map List

click on ‘Refresh Map List’.

The window shown should have a section at the very bottom for the ‘folder containing converted maps’. Set this to your preferred directory. All imported/converted maps will be saved in this location. Its default location is usually difficult to find later, so this is best set to a new directory in your main “Maps” directory.

Next, click “add folder” and select the folder with your two new files, the PNG and JPR files for the maps you wish to import into the list of map folders.

Then make sure you tick the ‘load all maps now’ option, and click on ‘OK’. This will import the maps you have defined in the jpr/png files, convert them, and save the converted results in memorymap format (qct) in the specified folder.

You can now see the map in the map list. Select it, tick the Open in new window check box and check out your new map.

When done, go back to Map List and remove the folder containing the jpr/png files from the map file folder list – so it no longer reads from there. You’ll need to click on the Refresh Map list to get the dialog box up that lists the folders MM is searching.

To get the converted map onto your Android device, copy the .QCT file from the directory you selected to save your converted map to your android device in the /downloaded/memory-map directory.

You can then use the .QCT map on your android device by selecting maps, Map Types (make sure JPR files are selected) and then “More Maps” and “All Maps on Device”.  The map should then show up in the list of maps.  If not, return to the main screen on the android app, and scroll (or search) to get to a place where one of your new maps covers, then repeat the process of selecting map types and displaying all maps on device. It should show up then.

If your android has not been used for displaying 3rd party maps before, the app will ask you to license the feature. Just say yes, or activate, or whatever.  Just like the PC application, you can move the license later if you change phone/tablet.

The same process should work for the iPhone/iPad version, I’m just not sure about the coping from PC to iPhone step or final directory, but, if you are an iPhone user, hopefully that is an easy enough step.
