Map projections and coordinate systems

Getting started with map projections An overview of map projections Projection basics the GIS professional needs to know About the geoid, ellipsoid, spheroid and datum, and how they are related Identifying an unknown coordinate system Converting Degrees Minutes Seconds values to Decimal Degree values Geographic coordinate systems About geographic coordinate systems Spheroids and spheres Datums North American datums What happens to features at +/-180 (dateline)? Projected coordinate systems Geographic transformations Geographic transformation methods Equation-based methods Grid-based methods Supported map projections List of supported map projections Aitoff Alaska Grid Alaska Series E Albers Equal Area Conic Azimuthal Equidistant Behrmann Equal Area Cylindrical Bipolar Oblique Conformal Conic Bonne Cassini-Soldner Chamberlin Trimetric Craster Parabolic Cube Cylindrical Equal Area Double Stereographic Eckert I Eckert II Eckert III Eckert IV Eckert V Eckert VI Equidistant Conic Equidistant Cylindrical Equirectangular Fuller Gall's Stereographic Gauss-Kruger Geocentric Coordinate System Geographic Coordinate System Gnomonic Great Britain National Grid Hammer-Aitoff Hotine Oblique Mercator Krovak Lambert Azimuthal Equal Area Lambert Conformal Conic Local Cartesian Projection Loximuthal McBryde-Thomas Flat-Polar Quartic Mercator Miller Cylindrical Mollweide New Zealand National Grid Orthographic Perspective Plate Carree Polar Stereographic Polyconic Quartic Authalic Rectified Skewed Orthomorphic Robinson Simple Conic Sinusoidal Space Oblique Mercator State Plane Coordinate System Stereographic Times projection Transverse Mercator Two-Point Equidistant Universal Polar Stereographic Universal Transverse Mercator Van der Grinten I Vertical Near-Side Perspective Winkel I Winkel II Winkel Tripel Vertical coordinate systems About vertical coordinate systems Vertical datums Geoid
