Geovisualization encompasses a wide variety of applications, from simple map displays with various points of interest, to navigation in unfamiliar space, to complex applications that help us every day. With themed maps, users can get to know their surroundings better as well as new points of interest. The next level is then represented by applications that allow the user to modify the maps themselves. Thanks to open souce projects with a wide community of users, cartography is more accessible than ever before.

OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result commonly used to make electronic maps, inform turn-by-turn navigation, assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine and editor. OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public under free licences in 2004. Initially, maps were created only via GPS traces, but it was quickly populated by importing public domain geographical data such as the U.S. TIGER and by tracing permitted aerial photography or satellite imagery. OpenStreetMap's adoption was accelerated by Google Maps's introduction of pricing in 2012 and the development of supporting software and applications. The database is hosted by the OpenStreetMap Foundation, a non-profit organisation registered in England and Wales and is funded mostly via donations.

OpenStreetMap is a libre and free online database of geodata which can be edited by everyone and is used by millions of people. However, contributing can be challenging or intimidating to non-technical users. Therefore there are webapps whose goal is to make it trivial to see and update information on OpenStreetMap. This is achieved by showing only features related to a single topic of interest on the map - from playgrounds, public toilets and bicycle rental places to charging stations and public tap water spots.

Route mapping refers to the process of visually depicting a particular route or trip on a map, often involving waypoints, landmarks and other geographical data. The aim is to provide a clear, interactive, and spatially accurate representation of a route’s course. Route mapping solves puzzles for various sectors via navigation, travel planning, and logistics visualisation. Unlike route planning software which focuses on optimising logistics, and efficiency, route mapping software’s primary role is to create visual and understandable maps.
