Knowra Computer cartography Computer cartography Computer cartography uses digital tools to create, edit, analyze, and produce maps. It combines cartographic design with spatial data and computational methods.
Map projection : A mathematical transformation that represents locations on a curved surface on a flat map. Projection choices determine how digital maps distort area, shape, distance, and direction.
Vector graphics : Graphics represented by geometric paths and shapes rather than fixed grids of pixels. Vector features let maps represent roads, boundaries, and symbols with editable geometry.
Web mapping : The delivery and use of maps through web browsers and internet-connected applications. Web mapping makes computer-produced maps interactive and widely accessible.
Roger Tomlinson : A geographer who led development of the Canada Geographic Information System in the 1960s. His system demonstrated how computers could store and analyze mapped information at national scale.
Manual cartography : The creation and reproduction of maps through hand drafting and other non-digital techniques. It contrasts with software-based editing, automated operations, and digital output.
Geospatial data : Data that describes locations, shapes, or attributes associated with places on Earth. Computer maps are built from spatial datasets rather than only drawn marks.
Raster graphics : Images represented as grids of pixels, each storing a color or measured value. Raster grids support imagery and continuous surfaces such as elevation.
Online mapping : The use of internet services to view, search, and interact with digital maps. Online map services bring cartographic tools into everyday navigation and information systems.
Canada Geographic Information System : A pioneering computer-based system developed to inventory and analyze Canada's land resources. Its creation established an early practical model for computerized mapping and spatial analysis.
Computer-aided design : The use of computer software to create, modify, and document technical designs. CAD shares digital drawing tools but is not inherently organized around geographic data.
