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)?

Editing and data compilation

An overview of editing and data compilation Getting started with editing Common editing tasks Common point editing tasks Common line editing tasks Common polygon editing tasks Common annotation editing tasks Common multipoint editing tasks Editing data in a different projection 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 Editing attributes Editing attributes Copying and pasting attributes Deleting attributes Editing with default values and attribute domains About updating data using SQL 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 Using a digitizer Spatial adjustment An overview of spatial adjustment Adding the Spatial Adjustment toolbar Setting up the spatial adjustment Working with links Working with link files and control point files Previewing and performing the adjustment Transferring attributes between features 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 About editing relationships and related objects Editing relationships and related objects COGO
