Abstract
V magistrskem delu se na kratko sprehodimo skozi zgodovino kart in poskusimo premisliti, katere lastnosti zemljevida so za nas pomembne. Podrobneje preučimo družino konformnih stožčastih projekcij ter Mercatorjevo in stereografsko projekcijo, za kateri se izkaže, da sta robna primera te družine. Poiščemo bijekcijo med Mercatorjevo in stereografsko karto. Bolj se posvetimo tudi popačenosti projekcij. Ugotovimo, da obstaja kartografska projekcija z minimalnim popačenjem na zaprtem disku in da je to azimutna ekvidistančna projekcija, katere predpis tudi izpeljemo. Na popačenje pogledamo še nekoliko drugače in spoznamo Tissotove indikatrise ter poiščemo predpis zanje za nekate pogostejše karte. Na koncu še pokukamo v svet poliedrnih projekcij.

Title:Maps and their projections
Abstract:
In the thesis we briefly go through the history of maps and try to find out which properties of maps are important to us. More accurately we study the family of the conformal conical projections, Mercator and stereographic projection. For Mercator and stereographic projections we find out, they are the limit cases of conformal conical projections. We also study more accurately the distortion of distances in map projections. We find out that the cartographic projection with the minimum distortion on a closed disc exists and this is the azimuthal equidistant projection, for which we find also the prescription. We look at the distortion from a different point of view, and we meet the Tissot’s indicatrix. We find the prescriptions for the indicatrix in some more common cartographic projections. In the end we make a brief look in the world of polyhedral projections.

Keywords:projection, map, sphere, distortion, Tissot, indicatrix, polyhedron, Mercator projection, stereographic projection, azimuthal equidistant projection
