EOTopo Digital Maps

The purpose of this article is to outline the different setup processes (and options) for buyers of EOTopo – simply find the information that applies to you.

EOTopo is not an app - nor is it a mapping system. EOTopo is a digital map and data set. To use these maps you will need to have a device with GPS mapping capability (of which there are many options). Depending which device (and software) you use, the method you use to install the EOTopo files will vary.

If this is your first time using digital map files, or installing additional map files to an app or device, you may not have realised the intricacies of the process. Each device and mapping software option handles the map installation process differently, so the setup you need to perform could be quite different to the next person (unless they are using exactly the same setup). For this reason, you could get confused if you try to ask for help from other EOTopo users and hence we have prepared this article. Simply scan through the list of headings and jump to the information that applies to you.

When buying EOTopo, you must know what device you are intending to load the maps onto as this will determine which of the 4 options you should buy. The map files on the SD and USB are provided in OZF4 and ECW format, the download option also offers both of these formats, as well as MMR (Mud Map) format. It is most likely that one of these formats will be compatible with your setup but please check the mapping software on your device (or purchase/load) mapping software to ensure your device is capable of using one of these file formats.

Note however, that if you are an Apple device user, or if you wish to use EOTopo maps in the Memory-Map app, then you cannot use the OZF4 or ECW formats. Memory-Map has its own file format so please be sure to select the correct EOTopo product when you purchase. The Memory Map Starter Pack (download only) contains the files in a special Memory Map format.

All EOTopo products feature topographic maps in various scales and formats plus additional compatible waypoint files with over 80,000 POIs. A popular selection of these features (such as Caravan Parks) are embedded onto the topographic base map file, but to find all POIs you have access to refer to them on demand via your mapping software once you have installed the applicable files to your device.

Compatible Devices

To use EOTopo maps for trip planning and navigation you will require a device with either an external or inbuilt GPS Receiver as well as Mapping Software. Subsequently the EOTopo buying option that you select will also depend upon your device and software type.

Devices and Software Options:

  • Windows Laptop/Notebook (with an external GPS Receiver) or Windows Tablet - Requires either OziExplorer PC, TrackRanger or Memory Map PC

  • Android Phone or Tablet - Requires either OziExplorer Android, Memory Map Android or Mud Map Android

  • iPhone or iPad (Wi-Fi only iPad needs an external GPS Receiver) - Requires Memory Map iOS or Mud Map iOS

  • GPS Device with Windows CE - Requires OziExplorer CE (if not already loaded)

  • Hema Navigator - Is already loaded with compatible EziOzi Software Program

  • VMS GPS Devices - Is already loaded with compatible VMS Off-Road Software and OziExplorer CE*
    (*may be trial version and require an OziExplorer CE Licence purchase)

  • Mud Map M7 - Is already loaded with OziExplorer CE*
    (*this is not the current 2.40 version more details below)


External GPS Receivers can also be utilised by devices that already have an inbuilt GPS receiver to improve the device's battery life and GPS accuracy. Trial versions of many of the software programs listed are available for free download so that you can familiarise yourself with the program prior to purchase.

Non-Compatible Devices

EOTopo is provided in the Raster Map format, and therefore cannot be used in devices that require Vector Maps. This includes Tom-Tom, Navman, Garmin and Magellan GPS Units, as well as most pre-installed vehicle Sat-Nav systems. There is one exception, the Garmin Monterra has an Android OS, so this could be set-up using the same process detailed in the EOTopo with OziExplorer Android section of this article.

EOTopo with Memory Map

The Memory Map product is available for use on Windows, Android and iOS devices. It is currently the only software option that allows you to use EOTopo maps on iOS devices (iPhone or iPad). It is important to note that the Memory Map software only allows you to use files in their proprietary format.

DO NOT purchase the EOTopo Maps on SD or USB, these files will not work in a Memory Map application. Instead follow the below procedure.
The first step in this process is to download the version of Memory Map that is required for your device.

There are then two options for the purchase and installation of EOTopo Maps:

Option 1 - In-app Purchase
If you have downloaded Memory Map to an Android or IOS device (or already have this program installed on your device), you have the option to purchase EOTopo maps in-app. This means that the payment and delivery of maps is handled by either Google Play or iTunes directly on your device (no need to connect to a computer as per the second option shown below), there is also no requirement to create a Memory Map account. Please note that this is only recommended if you are using these maps on one or more mobile device with the same operating system.

Option 2 - Starter Pack Transfer and Direct Memory Map Purchase
If you have installed the Memory Map for PC Software, or intend to use the maps on both a PC and Mobile Device (or mobile devices with different operating systems), this option involves the set-up of an account with Memory Map so that you can share purchased maps across all of your devices (subject to purchase of the appropriate user licence).

First of all, download the EOTopo Starter Pack*
(*Select the "Save As" option. Note that the EOTopo Starter Pack is a zip file, you will need to “Extract All” files for use).

Then follow the instructions found here (find the instructions for your Memory Map version in the list)


The below image shows the EOTopo Starter Pack Zip File, when clicked on with the right hand mouse button, a menu will appear to extract all files and save as an unzipped folder.

EOTopo with Mud Map App

The Mud Map App is available for use on Android and iOS devices (iPhone or iPad). This program only allows you to use files in their proprietary format (MMR). MMR format EOTopo files are currently only available with the purchase of the EOTopo Download product (are NOT supplied on the USB or SD).
The first step for set-up is to purchase the relevant Mud Map app for your device.

The next step is to purchase the EOTopo Download Option ($89.95 or $84.45 for Members) from this page: EOTopo 200K the download option is found under "Buying Options".

You will then need to download all MMR files from the EOTopo Download Page (you will be sent the link to this page following your purchase).

Once you have downloaded the maps, you can then transfer them to the needed device.

Instructions for Mud Map Android:
  • Step 1: Connect your Android device to your computer, it should mount as a disk and accessed via File Explorer.

  • Step 2: In file explorer, find your Android device and go to Android > Data > com.mudmap.android.mm2au4x4 > files. If the files folder is not there, create it (right click and select new folder > use "file" as the folder name)

  • Step 3: Open the app on your device and go to Menu > Maps > Import Maps > then follow the prompts.

Instructions for Mud Map iOS:
  • Step 1: Connect your iOS device to your computer and open iTunes.

  • Step 2: Go to Your Device > Apps > Under File Sharing click on Mud Map 2 > Click Add > Select .mmr files > Click Sync to copy these files to the device.

  • Step 3: Open Mud Map on your device and go to Menu > Maps > Import Maps > then follow the prompts.

EOTopo with Mud Map M7

Compatible with EOTopo SD or USB, the Mud Map M7 has an older version of OziExplorer CE which does not support OZF4 files. Mud Map do not recommend an update to the latest version of OziExplorer, instead they suggest that you use the ECW and .map files.

If you are planning on inserting the EOTopo SD for use with the device we would suggest the first step is to create a new folder on the SD Card and transfer the ECW and corresponding .map files into this folder. The ECW files are found in the ECW folder on the and the .map files are found in the OZF folder (there needs to be a corresponding .map file loaded for every ECW file).

You can then insert the EOTopo SD card into the M7 device and configure this new folder as an additional map file path in the CE program (as per CE instructions).

As with OziExplorer CE you will need to transfer all files found in the Name Search folder on the EOTopo SD/USB to the Name Search folder found on the M7 device (following the OziExplorer Data file path).

EOTopo with TrackRanger

Compatible with EOTopo SD/USB or Download, TrackRanger is a digital map viewing and navigation program available for use on Windows Laptops/Netbooks and Tablets. A GPS Receiver (either internal or external) is required to use this program for navigation.

TrackRanger have developed a specific installer for EOTopo, simply follow the instructions found in the Installing EOTopo Maps to TrackRanger PDF.

EOTopo with OziExplorer (Full PC Version)

Compatible with EOTopo SD/USB or Download, OziExplorer (Full PC Version) is a digital map viewing and navigation program available for use on Windows Laptops/Netbooks and Tablets. A GPS Receiver (either internal or external) is required to use this program for navigation.

OZF4 files are optimised for use with OziExplorer, so you will only require this particular format for use in any of the OziExplorer Software options.

The first thing that you need to determine is the destination folders configured in OziExplorer to source Maps and Name Search files from OziExplorer.
To find this, go to “Configuration” in OziExplorer, on the “System” tab it will display the file path for both the OziExplorer “Maps” and “Data” folders. From your EOTopo SD or USB you will need to copy the folder named “OZF” to your OziExplorer “Maps” folder, and the two files in the EOTopo's “Name Search” folder to the OziExplorer "Name Search" folder (found by going up one folder from “Data").


The below image shows the Configuration menu in OziExplorer, and the corresponding folders as found in Windows File Explorer. To go direct to the relevant folder, click on the "Folder" button next to the relevant File Path.

EOTopo with OziExplorer CE

Purchase Notes:

Compatible with EOTopo SD or USB, OziExplorer CE is a digital map viewing and navigation program available for use on Windows CE devices. Windows CE is the operating system for many generic and branded GPS devices on the market a list of these can be found on the OziExplorer website. If your device has a full version of OziExplorer pre-installed no further purchase is necessary; if a trial version is installed you will need to purchase a CE Upgrade Licence; if your CE device did not come loaded with any version of OziExplorer, you will need to purchase the OziExplorer (Full PC Version) as well as the CE upgrade to be able to load this program to your device.

ExplorOz have developed a custom interface (otherwise known as a "skin") for OziExplorer CE, called EOZi. EOZi is an add-on to the base program and is designed for ease of usability when using EOTopo maps in the OziExplorer CE program. At under $10, it's well worth it.

EOTopo Set-up:

EOTopo Maps and Data can be transferred as per instructions for OziExplorer Full Version, however this program also allows you to configure multiple map file paths – this is useful if you wish to have maps stored in different locations (for example using external storage such as the EOTopo SD Card). To do this simply insert the SD card into your device and configure the "OZF" folder as one of your maps folders. Please note that only one Data folder can be configured so you will need to transfer the files found in the EOTopo "Name Search" folder on the SD to the default OziExplorer "Name Search" folder (found by going up one folder from "Data").


The below image shows how to navigate to the Configuration and Map & Data Files menus in OziExplorer CE, as well as the "Get Path" function that will allow you to add a new Map File Path.

EOTopo with OziExplorer Android

Purchase Notes:

Compatible with EOTopo SD or USB, OziExplorer Android is a map viewing and navigation program available for use on Android Smartphones and Tablets. This program is not available for purchase from ExplorOz. To download and purchase OziExplorer for Android, please go direct to the OziExplorer Android Page.

ExplorOz have developed a custom interface (otherwise known as a "skin") for OziExplorer Android, called EOZi. EOZi is an add-on to the base program and is designed for ease of usability when using EOTopo maps in the OziExplorer Android program. At under $10, it's well worth it.

EOTopo Set-up:

The Configuration Menu in OziExplorer Android is found by clicking on the Show Menu icon on the far bottom left of the Screen, then click “Main Menu”, then “Configuration”, then “General Settings”, this will show you the Map File and Data File Paths.

You can either transfer the maps to the relevant folders as per the instructions for OziExplorer full version, or if you have limited storage space on the device, you can insert the EOTopo SD Card into your Android device and can change the file paths – for Maps configure this to the OZF folder, and for Data configure this to the Name Search Folder.


The below image shows the Main Menu, General Settings and Configuration Menu for OziExplorer Android. The Configuration Menu allows you to view/change the Map and Data File Paths.

Further OziExplorer Help

The information regarding use of EOTopo in the various versions of OziExplorer has been deducted by reading help files on the OziExplorer website, and by downloading trial versions of this software for testing. The three links below point directly to help files on Map Search/Configuration for each of the three software versions:

EOTopo with Hema Navigator

Purchase Option:

If you are considering purchasing a Hema Navigator, the ExplorOz Shop has an exclusive Hema Navigator 7 - EOTopo Edition, which comes with additional mapping (EOTopo200K as well as the standard Hema Maps and Software) loaded onto a 16GB micro SD card. To use, simply replace the standard 8GB micro SD in the device with this replacement SD. Go to the Buying Options tab to make your choice and select the Hema Navigator 7 - EOTopo Edition buying option.

Already Own a Navigator Device:

  • Compatible with EOTopo SD or USB, The various models of the Hema Navigator run a custom interface of OziExplorer CE. If you have a HN1, HN5, HN5i or HN6 you will need to update this to the latest version of OziExplorer so that your device can read OZF4 files, the links below have all of the necessary instructions for your device model (this step is not needed for the HN7):

    Update OziExplorer CE on a HN1, HN5 or HN5i: Update OziExplorer CE for Hema Navigator

    Update OziExplorer CE on a HN6: Update OziExplorer CE for Hema Navigator

  • You will then need to transfer the needed map and name search files to the Navigator’s SD Card. As there is limited space on this card, you will need to transfer specific files. Firstly, find the “OziExplorer Maps” folder on the Navigator’s SD Card and create a “New Folder”, name it something like “EOTopo Maps”.

  • Then open the OZF folder on your EOTopo SD or USB, you will need to transfer the following files to the “New Folder” that you have just created.

    EOTopo 200K Australia.ozf4
    EOTopo 1M Australia.ozf4
    EOTopo 2.5M Australia.ozf4
    EOTopo 5M Australia.ozf4
    EOTopo 10M Australia.ozf4
    EOTopo 200K Australia.map
    EOTopo 1M Australia.map
    EOTopo 2.5M Australia.map
    EOTopo 5M Australia.map
    EOTopo 10M Australia.map

  • Then find the HNOZi Folder on the Hema’s SD, open it, and you should see a folder called “Name Search”. On the EOTopo USB or SD, you will also see a folder named “Name Search”, transfer the two files in the EOTopo’s “Name Search” folder to the Navigator’s “Name Search” folder. You can then use the functions found in Off Road Navigation on the device to load the EOTopo Maps, and EOTopo Name Search files.

Further Hema Navigator Help

The information above has been deduced from the following help file, which is referring to transferring Greg Harewood’s products to the Hema Navigator. The procedure is still very much the same, so you may find the original help file useful:

OziExplorer 4WD Mode - Using Greg Harewood Map DVDs With Hema Navigator

EOTopo with VMS GPS

Compatible with EOTopo SD or USB, there are two navigation software options available on the VMS GPS devices.

The first option is VMS Off Road. VMS GPS devices have a “VMS Map Converter” which can then be transferred to your computer and used to convert the EOTopo ECW files to the correct format. Instructions are found on the VMS FAQ page, (scroll to the “How do I add new off-road maps section”).

The second option is OziExplorer CE (if trial version is installed you will need to purchase the CE upgrade licence). To use the EOTopo maps in OziExplorer CE, transfer the OZF4 and Name Search files as listed above for the Hema Navigator into the relevant folders for Maps and Name Search Data found on the VMS device or VMS SD Card.
