Coordinate geometry8/15/2023 ![]() ![]() You can use a simple line feature class or manage parcel lines in a parcel fabric. Measured lines can also represent circular arcs and spiral curves. Lines can represent measured distances and directions.You can use a simple point feature class with x, y, z attributes to represent these points, or use a parcel fabric to manage parcel points. Points can also represent surveyed points and have known x,y,z coordinates. Points can represent the endpoints of measured lines and curves.In addition to COGO-enabled line features, you can use simple point, line, and polygon features to represent COGO features described below. COGO fields are used to store survey measurements typed into COGO-aware editing tools. Spirals describe transitions to and from circular curves or straight tangents, for example, to record the designed alignment for a roadway or railroad.Įnabling COGO for a line feature class adds COGO attribute fields and COGO-enabled labeling to the feature class. ![]() The second radius can be set to infinity. Curved lines include a radius, angle, arc length, and chord direction.Straight lines are described with a direction and a distance.In ArcGIS Pro, COGO descriptions comprise a set of measurements that define a line feature. These points are known as control points, monuments, or cadastral reference points. Survey plans can include references to points with known coordinates that spatially locate or georeference COGO features within a coordinate system. An example survey plan shows COGO descriptions for a road centerline and parcel boundaries adjoining the road. The following example survey plan shows COGO measurements for a road centerline and parcel boundaries adjoining the road. Coordinate geometry (COGO) is used to map the location of features and their boundaries measured on the ground and recorded on survey plans, deed descriptions, and other types of physical or electronic land record documents.ĬOGO measurements typically describe features relative to each other. ![]()
