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

Editing and data compilation

An overview of editing and data compilation Getting started with editing Common editing tasks Creating new features About creating new features Creating point features and vertices Creating lines and polygons Creating segments using angles and lengths Creating segments using angles from existing segments Creating segments that are circular arc curves Creating segments by tracing features Creating buffers Mirroring features Combining features from different layers Intersecting features Merging and separating features Copying parallel line features Creating a fillet curve between two lines Creating cul-de-sac lines Creating lines with the Traverse window Creating lines with the 2-Point Line window Creating lines with the Offset Line window Editing existing features Moving features Rotating features Copying and pasting features Deleting features Adding and deleting vertices Moving vertices Editing attribute values of a vertex Reshaping lines and polygons using a sketch Splitting polygon features Splitting line features Trimming lines Extending lines Flipping lines Scaling features Clipping features Stretching a feature's geometry proportionately Simplifying and smoothing features Editing attributes Editing annotation An overview of editing annotation Creating new annotation features Creating and editing annotation that follows features Editing the size and position of annotation features Editing annotation in the Attributes dialog box Editing the appearance of annotation features Editing feature-linked annotation Editing dimension features About editing dimension features Creating dimension features Modifying a dimension feature's geometry and style Using a digitizer Spatial adjustment Editing topology About topology Topology rules Topology error fixes Basic topology tasks Creating a map topology Editing features in a topology Editing shared geometry Topology validation Topology errors and exceptions Correcting topology errors Finding features with shared topology elements Clearing selected topology elements Changing the symbology for topology features Making new features with topology tools Editing relationships and related objects COGO
