The 46 pages that link to Map projection, each with the reason it gives.

• Geographic information systemRelated: GIS maps must project coordinates to display Earth on flat screens or paper.

• CartographyRelated: Projection choices shape distortion in every flat map.

• Geographic coordinate systemRelated: It converts geographic coordinates into planar coordinates for many maps.

• Mercator projectionNarrower topic: The Mercator projection is one specific way to flatten the globe.

• Map scaleRelated: Projection distortion can make the stated scale vary across a map.

• Spatial analysisRelated: Projection choices affect measured shapes, areas, distances, and directions.

• Thematic mapRelated: Projection choices distort area, shape, distance, or direction in the geographic frame of a theme.

• Coordinate reference systemRelated: Projected CRSs use this transformation to express locations in planar coordinates.

• Gerardus MercatorNarrower topic: Mercator’s best-known contribution is a specific projection for mapping Earth.

• MeridianRelated: Map projections transform the curved paths of meridians into lines or curves on maps.

• Scale (geography)Compared with: Projection changes shape and distance, while geographic scale specifies analytical level or map ratio.

• Stereographic projectionNarrower topic: Stereographic projection is a conformal member of the broader family of map projections.

• Topographic surveyingRelated: Projected coordinates let survey results be plotted and used on plan sheets.

• World Geodetic System 1984Compared with: WGS 84 defines a reference for positions; a projection transforms them for flat maps.

• World mapNarrower topic: Every flat world map depends on a projection that trades off geographic properties.

• Cartographic generalizationRelated: Projection distortion changes the shapes and distances that generalization must preserve or manage.

• Star chartRelated: Projecting the celestial sphere onto a page inevitably distorts some properties.

• Compass roseNarrower topic: Projection choices shape how directional lines and bearings appear across a chart.

• Spatial dataRelated: It explains how Earth coordinates become usable in flat maps.

• CartogramCompared with: Projections distort geometry to flatten Earth; cartograms distort it to encode data.

• Gall–Peters projectionNarrower topic: Its distortions arise from transforming Earth’s curved surface into a plane.

• Geographic information scienceRelated: Projection choices shape spatial measurements and map interpretation.

• History of cartographyRelated: Projection choices shape visual impressions of area, distance, and political centrality.

• Johann Heinrich LambertNarrower topic: Lambert developed projection methods that preserve area and support regional mapping.

• Abraham OrteliusRelated: The maps he compiled used projections to depict regions on printed pages.

• Celestial cartographyRelated: Projections let cartographers flatten celestial spheres and planetary globes into usable charts.

• Figure of the EarthRelated: Map projections require an Earth model to convert geodetic coordinates into map coordinates.

• Proportional symbol mapRelated: Projection distortion can alter the apparent placement and spacing of symbols.

• Robinson projectionNarrower topic: The Robinson projection is one method for transforming the globe onto a plane.

• Web mappingNarrower topic: Every flat web map must project geographic coordinates onto its display.

• Arno PetersNarrower topic: Peters’s proposal belongs to the broader problem of flattening Earth.

• Arthur H. RobinsonNarrower topic: Understanding projections clarifies the problem Robinson addressed with his world map.

• Earth ellipsoidRelated: Mapping systems use an ellipsoid to define the curved surface being projected.

• GeovisualizationRelated: Projection choices shape how geographic positions and spatial relationships appear.

• Computer cartographyRelated: Projection choices determine how digital maps distort area, shape, distance, and direction.

• Azimuthal equidistant projectionNarrower topic: This projection is a particular way to flatten the Earth.

• GeomaticsRelated: Projection choices determine how spatial data are distorted when mapped.

• Mark MonmonierRelated: Projection choices illustrate how unavoidable design decisions alter geographic appearance.

• Quantitative geographyRelated: Projection choices affect distance, area, and shape calculations in spatial analysis.

• Guillaume DelisleRelated: Even accurate positions required a projection to become a usable flat map.

• Ley lineRelated: Different projections can alter how straight a long site alignment appears.

• Oronce FineNarrower topic: Fine’s world maps depended on translating spherical geography onto paper.

• Technical geographyRelated: Projection choices shape how spatial data appear on flat maps.

• Two-dimensional spaceRelated: It turns Earth’s surface into a two-dimensional coordinate representation.

• Waldo R. ToblerRelated: Tobler analyzed projections as transformations with measurable geometric properties.
