批量计算直线或线段方位角：在ArcMap中右键调出【COGO】工具，并打开【编辑器】开启对“线段.shp”的编辑模式。 然后，选中所有线段后单击【COGO】工具最后一个命令（即“更新COGO属性”命令），此时属性表中的方位角和距离字段会被自动计算并填充。

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. COGO measurements typically describe features relative to each other.

The COGO functionality provided when editing in ArcMap with the COGO toolbar allows you to create and maintain your land parcels and other surveyed features in a geodatabase. There is other Esri functionality that provides similar capabilities, such as parcel editing and the COGO extension to ArcInfo Workstation .

2009年5月27日 · The coordinate geometry (COGO) traverse is used to compute a sequence of survey point locations starting from an initial known point. Each new survey point is defined by a traverse course and is used as the take-off point for the next course in the sequence.

Coordinate geometry (COGO) is used to define features relative to each other using dimensions and coordinates. In a traverse, COGO dimensions are entered to create a sequence of lines or sides of a polygon. When using the Traverse tool , straight lines are entered using a bearing or angle and a distance.

Enables COGO on a line feature class and adds COGO fields and COGO-enabled labeling to a line feature class. COGO fields store dimensions that are used to create line features in relation to each other. This tool modifies the input data.

In this exercise we will demonstrate the use of another set of COGO tools, Graphical COGO. It is set up to store points graphically and can be used with visualized COGO elements to perform MicroStation like manipulations which translate into actual coordinate geometry stored in …

• Choose COGO | Right of Way Offsets. See Accessing COGO. • From the Right of Way dialog, choose [X] Left and/or [X] Right and enter the individual offset distance for each. • Enter the type of label to give the offset points (explanation follows). If you forget how to specify an offset label, just press F1 for on-line help.

This lab demonstrates the use of the Traverse command to establish the West ¼ corner from Cogo point 105. Development of the right of way for the project requires the establishment of the West ¼ corner for Section 13

2009年5月27日 · About using simple COGO computations. Delta XY You can compute coordinates for a survey point based on a known difference in coordinates from a given start point. These coordinate differences are termed delta x,y. The direction of the computed coordinates from the start point is defined by the sign of the delta values as shown below:
