TopoFusion GPS Mapping software designed to plan and analyze trails using topographic maps and GPS tracks.



The software was created in 2002 by two brothers who were outdoor bikepacking enthusiasts and felt software could help them plan better trails. [3] They developed the first version of the software in 2002 and one included it as part of his doctorate dissertation on GPS Driven Trail Simulation and Network Production. [4] In 2004 the developers and one other jointly presented the paper Digital Trail Libraries which illustrated some of the graph theory algorithms used by the software. [5] [1] As of 2018 the software remains supported with refined functionality and improved support for additional maps and GPS Devices. [6]


The software was designed to plan and analyze trails. [7] When used for planning proposed routes may be planned and checked against different maps, and the result(s) downloaded to a GPS tracking device. [7] Topofusion is particularly noted for eased of switch and combining maps and for capability of simultaneously managing multiple trails. [8] After a trail has been executed the resultant GPS log can be uploaded to TopoFusion and the actual route analyzed with the addition of any photographic images recorded on route. [7]

The product is marketed as a fully featured 'professional version and a more basic version with reduced functionality at lower cost. A fully featured trial version which is not time limited is available which restricts usability by watermarking map display tiles by overlaying the word 'DEMO'. [2] The software is available directly Microsoft Windows only, [9] however TopoFusion has claimed users have reported success using VMWare Fusion and Parallels emulation on Mac OS. [3] [10]


TopoFusion has been found useful by those engaged in the sport of geocaching. [11]

The software has been used in assisting analysis of GPS routes. A survey reported in 2004 of GPS tracking of motorists visiting the Acadia National Park in Maine, United States was assisted by use of Topofusion to review the scenes visited. [12] It has also been used in studies of agriculture transportation logistics. [1]

TopoFusion can also assist in determining where photographs have been taken on a trail and can geocoded photo the image or tag it onto a map. For this to be successful the digital camera's time must be synchronized with the GPS unit time, and both the GPS track and digital images made available to Topofusion. The time when the image was taken can then be matched to the time on the GPS log and this enables the image to be enhanced with geocode fields when Real-time geotagging was not available when the image was taken. TopoFusion can also optionally annotate maps with images. [13]

Geographic information system System to capture, manage and present geographic data

A geographic information system (GIS) is a conceptualized framework that provides the ability to capture and analyze spatial and geographic data. GIS applications are computer-based tools, that allow the user to create interactive queries, analyze spatial information output, edit data presented within maps, and visually share the results of these operations.

Geocaching outdoor recreational activity

Geocaching is an outdoor recreational activity, in which participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called "geocaches" or "caches", at specific locations marked by coordinates all over the world.

Exif metadata standard in digital images

Exchangeable image file format is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras, scanners and other systems handling image and sound files recorded by digital cameras. The specification uses the following existing file formats with the addition of specific metadata tags: JPEG discrete cosine transform (DCT) for compressed image files, TIFF Rev. 6.0 for uncompressed image files, and RIFF WAV for audio files. It is not used in JPEG 2000 or GIF.

Geotagged photograph photograph which is associated with a geographical location by geotagging

A geotagged photograph is a photograph which is associated with a geographical location by geotagging. Usually this is done by assigning at least a latitude and longitude to the image, and optionally altitude, compass bearing and other fields may also be included.

GPS Drawing, also known as GPS Art and Strava Art, is a method of drawing where an artist uses a Global Positioning System (GPS) device and follows a pre-planned route to create a large-scale picture or text on a map. Alternatively, in the freestyle method of GPS Drawing, the path followed by the GPS receiver is random. Artists usually run or cycle the route—while cars, vans, boats and aeroplanes are utilized to create larger pieces.

Geotagging Act of associating geographic coordinates to digital media

Geotagging, or GeoTagging, is the process of adding geographical identification metadata to various media such as a geotagged photograph or video, websites, SMS messages, QR Codes or RSS feeds and is a form of geospatial metadata. This data usually consists of latitude and longitude coordinates, though they can also include altitude, bearing, distance, accuracy data, and place names, and perhaps a time stamp.

Geocoding is the process of taking input text, such as an address or the name of a place, and returning a latitude/longitude location on the Earth's surface for that place. Reverse geocoding, on the other hand, converts geographic coordinates to a description of a location, usually the name of a place or an addressable location. Geocoding relies on a computer representation of address points, the street / road network, together with postal and administrative boundaries.

OpenStreetMap Collaboratively edited world map available under free Open Database License

OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. The geodata underlying the map is considered the primary output of the project. The creation and growth of OSM has been motivated by restrictions on use or availability of map data across much of the world, and the advent of inexpensive portable satellite navigation devices.

Point of interest specific location that someone may find useful or interesting

A point of interest, or POI, is a specific point location that someone may find useful or interesting. An example is a point on the Earth representing the location of the Eiffel Tower, or a point on Mars representing the location of its highest mountain, Olympus Mons. Most consumers use the term when referring to hotels, campsites, fuel stations or any other categories used in modern automotive navigation systems.

Georeferencing means that the internal coordinate system of a map or aerial photo image can be related to a ground system of geographic coordinates. The relevant coordinate transforms are typically stored within the image file, though there are many possible mechanisms for implementing georeferencing. The most visible effect of georeferencing is that display software can show ground coordinates and also measure ground distances and areas. In other words, Georeferencing means to associate something with locations in physical space. The term is commonly used in the geographic information systems field to describe the process of associating a physical map or raster image of a map with spatial locations. Georeferencing may be applied to any kind of object or structure that can be related to a geographical location, such as points of interest, roads, places, bridges, or buildings.

GPS navigation software usually falls into one of the following two categories:

  1. Navigation with route calculation and directions from the software to the user of the route to take, based on a vector-based map, normally for motorised vehicles with some motorised forms added on as an afterthought.
  2. Navigation tracking, often with a map "picture" in the background, but showing where you have been, and allowing "routes" to be preprogrammed, giving a line you can follow on the screen. This type can also be used for geocaching.
Satellite navigation device device that determines its position by analyzing satellite signals

A Satellite navigation device, colloquially called a GPS receiver, or simply a GPS, is a device that is capable of receiving information from GNSS satellites and then to calculate the device's geographical position. Using suitable software, the device may display the position on a map, and it may offer routing directions. The Global Positioning System (GPS) is one of a handful of global navigation satellite systems (GNSS) made up of a network of a minimum of 24, but currently 30, satellites placed into orbit by the U.S. Department of Defense.
