Knowra Geovisualization Geovisualization Geovisualization is the interactive visual exploration and analysis of geographic data through maps and related representations. It combines geographic information, visual encoding, and user interaction to reveal spatial patterns and relationships.
Geographic information system : A system for capturing, managing, analyzing, and displaying data linked to locations. Geovisualization uses GIS data and tools, while emphasizing interactive visual exploration.
Geospatial data : Data that describe phenomena associated with locations on or near Earth. It is the material geovisualization represents and makes available for analysis.
Public participation GIS : The use of GIS methods to involve the public in planning and decision-making. Interactive maps let participants contribute local knowledge and examine proposed changes.
Static map : A fixed map image that does not change in response to user interaction. Unlike geovisualization, it offers no interactive exploration of alternate views or selections.
Cartographic visualization : The use of maps to visually represent data and support analysis. It supplies map-based visual methods that geovisualization extends with interaction.
Spatial analysis : Methods for examining the locations, distributions, and relationships of geographic phenomena. Geovisualization supports spatial analysis by making its patterns inspectable.
Disaster response : Coordinated actions to prepare for, manage, and recover from emergencies. Geovisualization helps responders inspect hazards, impacts, and resources across space.
Scientific visualization : The visual representation and analysis of scientific data, often including spatial simulations and measurements. It can share techniques with geovisualization but is not defined by geographic data.
Visual variables : Graphic properties such as size, shape, color, and position used to encode information visually. These properties determine how geographic patterns become visible on a map.
Map projection : A mathematical transformation that represents Earth's curved surface on a flat map. Projection choices shape how geographic positions and spatial relationships appear.
