Coordinate Geometry (COGO) and ground to grid correction tools for editing are used to map the location of features and their boundaries measured on the ground and recorded in physical or electronic land record documents.
The editing tools listed in the following tables include additional functionality for editing COGO-enabled features and creating geometry based on the current ground to grid correction settings. You can use them with standard geodatabase features and features contained in parcel fabrics.
Feature construction tools
The tools in the following table are available when you are actively drawing a feature using a feature construction tool in the Create Features pane.
Tool | Description | Ground to grid distance factor | Ground to grid direction offset |
---|---|---|---|
Create two-point tangent or non-tangent circular arc segments based on specified parameters. | |||
Create clothoid spiral curves based on specified parameters. | |||
Solve basic analytic geometry problems to place a point feature or a vertex, such as finding the intersection of two radial distances or of two directions. | |||
Constrain the current segment to the specified direction value. | |||
Constrain the current segment to the specified distance. | |||
Create a vertex at the specified horizontal direction and distance measured from the last vertex. | |||
Specify direction and distance using on-screen text box controls. |
Feature modification tools
The tools in the following table are available in the Modify Features pane.
Tool | Description | Ground to grid distance factor | Ground to grid direction offset |
---|---|---|---|
Create a series of line features or a single polygon feature by typing values. Note:This tool supports single-handed data entry using the numeric keypad. | |||
Update the direction and distance attributes of a COGO-enabled line feature to match the selected feature geometry. Note:If ground to grid is turned on, the calculated values are rotated and scaled by the current correction settings. | |||
Create cul-de-sac geometry that is aligned with a selected line feature representing the centerline of a road. | |||
Create two-point COGO lines and arcs from selected line features. The feature is split at each vertex. | |||
Extend or trim a line feature to an existing feature boundary. Note:Check the Recalculate COGO attributes check box in the tool pane to recalculate existing COGO attributes values. | |||
Create a tangent circular arc between two segments by reshaping the first segment and trimming the second segment. | |||
Split straight and curved line features at intersections or inferred intersections. You can extend a line to an inferred intersection or create a segment. Note:Check the Recalculate COGO attributes check box in the tool pane to recalculate existing COGO attributes values. | |||
Split editable and visible features into two or more features. You can draw a line to create the split or select input cutting features and split only selected target features. | |||
Divide a single-part polyline feature into multiple features that have equal or varying distances or a percentage of the total length. |
Note:The distance factor is applied only if the Length or Arclength fields do not contain values and the tool is not set to distribute the remaining length equally or proportionally. | ||
Copy line features parallel or concentric to existing line features at a specified offset distance. | |||
Create features at specified distances along a line at a specified perpendicular offset from the line. | |||
Combine two or more features on the same layer that share coincident vertices into one feature. You can replace the existing feature, or keep it and create a feature. Note:Existing COGO attribute values are automatically recalculated. | |||
Split overlapping features on the same layer into individual segments at each intersection and delete coincident line segments. Note:Existing COGO attribute values are automatically recalculated. Null COGO attribute values remain as null values on the split lines. |
Measurement tools
The tools in the following table are available on the ribbon on the Map tab.
Tool | Description | Ground to grid distance factor | Ground to grid direction offset |
---|---|---|---|
Draw a line on the map to measure the straight-line direction and distance between two or more points. | |||
Measure one or more perpendicular offset distances from a baseline you draw. |
