SAVING changes, undoing changes, and exiting ARCEDITPut steps 1 - 4 in AML; 5 & 6 perform at prompt01/15/19 --- UTDallas POEC 6382 Applied GIS Software3Step 1 - Set Display Environment & Coordinate InputDISPLAY ENVIRONMENT•ARCEDIT: display 9999•ARCEDIT: &term 9999COORDINATE INPUT - specify the mode of interactive coordinate entry for ARCEDIT commands that require coordinate input. You can change this multiple times per session. Default is cursor; do not need to change for heads-up digitizing. •ARCEDIT: coordinate < CURSOR | TABLET | MOUSE>•ARCEDIT: coordinate keyboard •ARCEDIT: coordinate digitizer01/15/19 --- UTDallas POEC 6382 Applied GIS Software4Step 2 - Specify edit coverage and edit feature•Specify which coverage and which type of feature to be edited. These are called the edit coverage and edit feature. •During an ARCEDIT session you can change both frequently.•You can have up to ten edit coverages within an ARCEDIT session•The most recently specified edit coverages is the active one.•Editfeature can be abbreviated to EFARCEDIT: edit <cover>ARCEDIT: editfeature <feature_class>01/15/19 --- UTDallas POEC 6382 Applied GIS Software5Step 3. Set drawing environment for edit and back coverages•A back coverage is for display only; they are not edited, but may assist in editing another coverage. Designate a back coverage with the backcover command.*ARCEDIT: backcover <cover> {symbol}•An image can also be utilized as a background to the edit coverage; simply call the image *ARCEDIT: image 75069876.jpg•The backenvironment command specifies which feature classes will be drawn for the back coverage. ARCEDIT: backe arc polygon*Note: nothing will draw in your graphics window until the DRAW command is given01/15/19 --- UTDallas POEC 6382 Applied GIS Software6Step 3. Set drawing environment for edit and back coverages, (page 2)•The drawenvironment command specifies which feature classes will be drawn for the edit coverage. –The default setting assumes that no features will be drawn. You must specify each feature type to be drawn. –Each feature class can be drawn in a variety of ways -- see the on-line help for the drawenvironment command to review the options. The default for each feature class specified in the command line is ON, therefore it is not necessary to choose that option.•If editing arcs, it is a good idea to draw nodes with errors (dangling and pseudo) drawn with their special symbols (box for dangling, diamond for pseudo). The drawing environment will automatically update the symbols as errors are corrected or introduced. ARCEDIT: drawe arc node errors01/15/19 --- UTDallas POEC 6382 Applied GIS Software7Step 3. Set draw symbols for pseudo and dangling nodes (page 3)•NODECOLOR allows you to specify a color with which nodes are drawn when the edit coverage does not have a node attribute table.•NODECOLOR <NODE | DANGLE | PSEUDO> <color>–Arcedit: nodecolor dangle 2–Arcedit: nodecolor pseudo 301/15/19 --- UTDallas POEC 6382 Applied GIS Software8Step 3 Draw features (page 4)•Set the map extentARCEDIT: mape {* | DEFAULT | SELECT}ARCEDIT: mape <backcover>ARCEDIT: mape <xmin ymin xmax ymax>ARCEDIT: mape IMAGE <image>The DEFAULT argument sets the map extent to the edit coverage’s stored map extent. The SELECT argument will set the mape extent to span exactly the selected features in the edit coverage and edit feature.•Draw features specified up to this point (edit cover, backcover, image, if specified).ARCEDIT: draw01/15/19 --- UTDallas POEC 6382 Applied GIS Software9Step 4. Set snap environment and edit tolerances•The snap environment positions new or modified features to exactly match the positions of other features. •There are three types of snapping:–node snapping–arc snapping–general snapping•Will not snap features already digitized; it affects newly added or edited features only.01/15/19 --- UTDallas POEC 6382 Applied GIS Software10NODE SNAPPING (step 4, p.2)A new node is snapped to an existing node if it is within the node snapping distance. ARCEDIT: nodesnap <FIRST | CLOSEST | OFF> {DEFAULT | * | distance} Specifies whether the FIRST node found within the distance is snapped to, or the CLOSEST node. OFF turns nodesnapping off.01/15/19 --- UTDallas POEC 6382 Applied GIS Software11ARC SNAPPING (Step 4, p. 3)Arc snapping helps you snap new arcs to existing arcs. Arc snapping is used to correct undershoots and overshoots.ARCEDIT: arcsnap on {* | distance}ARCEDIT: arcsnap off01/15/19 --- UTDallas POEC 6382 Applied GIS Software12GENERAL SNAPPING (Step 4, p. 4)•General snapping ensures that features which should align precisely to others are snapped.–Example -- set the addition of point features which represent transformers in an electrical utility coverage to
