EOTopo

At ExplorOz, our mission is to deliver the most accurate and comprehensive digital topographic mapset of Australia. Every year, we release an updated version of our EOTopo maps, incorporating the latest data and improvements to ensure an unmatched resource for your outdoor exploration. This commitment to annual updates ensures that EOTopo stays relevant, reliable, and equipped with the most current geographical data available, together with an exceptional roads & tracks network, keeping you informed and on course throughout your journey.

EOTopo is developed entirely in-house and is proudly Australian-made. Unlike many competitors, who rely on repurposing outdated government mapping data—often up to 30 years old—EOTopo is built from the ground up using modern, high-quality data sources. While free maps or even some paid products might appear differently styled or branded, they often originate from the same outdated datasets. These maps can lack accuracy, omit crucial updates, and fail to reflect significant changes in Australia’s evolving landscape.

EOTopo stands apart by utilising advanced mapping techniques and combining the latest authoritative data sources, ensuring precision and reliability. This means that when you use EOTopo, you're not just getting a polished version of old information—you’re accessing a uniquely crafted, up-to-date, and meticulously curated map that reflects the reality of Australia today.

EOTopo maps are designed exclusively for use within the ExplorOz ecosystem and are fully integrated into the ExplorOz Traveller app, offering both offline and online functionality. These maps also display synced tracking content from the ExplorOz server and appear on destination pages (Places, Treks, Track Logs). This integration ensures a consistent, optimised mapping experience tailored specifically for ExplorOz users.

For offline use, EOTopo maps are designed exclusively for the ExplorOz Traveller app and the map data is simply downloaded through the app's integrated Data Manager. This integration ensures access to full map functionality from common devices already owned by most people such as phones, tablets and iPads, making it the ultimate and affordable navigation and trip planning tool for travellers exploring Australia.

The purchase of the Traveller app is managed through the Australian app stores for Apple and Android devices. EOTopo maps are available as a separate purchase, with a license linked to the user's ExplorOz account. By keeping these components separate, we offer a cost-effective solution for users with multiple devices or cross-platform needs. This approach provides flexibility, allowing users to buy and manage only what they need while ensuring seamless compatibility across devices. For more details, please refer to the licence terms and conditions on the relevant page.

At ExplorOz, our mission is to deliver the most accurate and comprehensive digital topographic maps for Australian travellers and adventurers. Each year, we release an updated version of our EOTopo maps, incorporating the latest data and enhancements to provide an unparalleled resource for navigation and trip planning. Here’s why annual updates are essential and how they benefit our users:

Australia's infrastructure, landscapes, and urban environments are in a constant state of change. To ensure the continued accuracy and reliability of our EOTopo maps, we provide annual updates that encompass all map features—not just roads and tracks. These updates include:

• New and updated utility names
• Proposed roads and connectivity projects
• Urban cycling paths, shared paths, and MTB parks
• Walking & hiking trails
• Water bodies, pipelines, powerlines, masts, and towers
• Incorporation of upgraded road surfaces
• Urban expansions, including new streets, bridges, buildings, and highways
• National parks and reserves
• Land boundaries, including Indigenous Protected Areas (IPA)

A key part of building the maps is the maintenance of the "ExplorOz Topo Roads" database, a unique and continuously updated dataset developed over 25 years. This database focuses on minor roads and tracks not actively maintained by government or main road authorities. It is refined through field research, satellite overlays, and user feedback to ensure accuracy for 4WD enthusiasts and remote travellers.

The data is incorporated into the annual EOTopo update through a process called data conflation, where we compare it side-by-side with information from various sources, including government datasets and open-source projects like OpenStreetMap (OSM).

Although the ExplorOz team actively contributes to OSM, the ExplorOz Topo dataset is kept separate from OSM. In some instances, we selectively integrate urban and infrastructure data from OSM into EOTopo to further enhance map accuracy and usability.

The EOTopo licence can be purchased in the ExplorOz Traveller app as an in-app purchase or direct from us via our shop.

EOTopo is sold separately from the Traveller app and is required for offline map usage within the app. There are 4 files (map packs) that together seamlessly comprise the full EOTopo high resolution mapset. Without an EOTopo licence, you can only download 1 of these map packs (the low-resolution map pack) which restricts the offline map from zooming to the full high resolution detail. Without the licence, you do not have access to the high-resolution, contour, and terrain map packs.

When you purchase an EOTopo licence, you gain access to a specific edition of the maps, identified by the production year. Each edition is supported for 4 years, allowing you to download and use the map packs as often as you like within the ExplorOz Traveller app, with no additional costs or subscriptions during the support period. For example, if you purchase EOTopo 2025, you can use and download the maps freely until 2029, or choose to purchase a newer edition before then. When a new edition is released, existing users can continue using their purchased edition (whilst it remains supported).

EOTopo is licensed to individual ExplorOz users via their ExplorOz account login, which is separate from your app store account. This means you only need to purchase one EOTopo licence, regardless of whether you download the maps to Apple or Android devices. Please note, however, that the Traveller app must be purchased separately for cross-platform use.

EOTopo licences apply to offline map use only. The Traveller app provides ongoing free access to the online edition of the latest EOTopo through regular app updates.

Buyer Guarantee

When you purchase your EOTopo licence, you're covered by our Buyer Guarantee, which ensures peace of mind for the first three months. If a new edition of EOTopo is released within this period, you'll receive a free update to the latest version. This guarantee is designed to protect you from unexpected updates shortly after your purchase. For example, if you recently purchased EOTopo 2024, the new 2025 licence will automatically be added to your account.

These files are not required and not compatible with the ExplorOz Traveller app. The downloads available here are for discontinued raster editions of EOTopo (2014-2019). These are only available to users with the old licences to enable downloading to new devices. To use these files, you will need raster mapping software. These files can only be downloaded one at a time.
