Editing and data compilation

An overview of editing and data compilation Getting started with editing About editing your geodatabase in ArcMap Adding the data you want to edit The structure of vector datasets Adding the editing toolbars Starting and stopping an edit session The sketch construction tools Using the snapping environment About setting distance units Setting direction measuring systems and units Shortcut keys for editing in ArcMap 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 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
