How to Manually Add coordinates for Point data

To manually add geospatial data for a point:

1. Click the button in the Points table of the Point and Polygon/Polyline List window.
2. From the Point window, enter the point number in the Point No. field. Note that this is a required field.

The fields available in the Points window will depend on the coordinate reference system that you selected.

3. Select the type of point that you are defining from the Point Type field.
4. Enter the local identifier for the point in the Point ID field. Note that this is a required field.
5. Do one of the following:
• To enter an absolute point, enter the coordinates in either the X/Longitude and Y/Latitude fields, or the MGRS field.

Absolute points are those points for which you know the coordinates. Relative points are those points for which you may not know the coordinates, but you do know the distance and bearing from an absolute point.

• To enter a relative point:
1. Enter the distance of the point from the absolute point in the Distance field.
2. Enter the bearing of the point relative to the absolute point in the Bearing field.
3. Select the point from which the distance and bearing are defined from the From Point list.
6. Enter a description for the point in the Point Description field.
7. Do one of the following:
• To save the point and close the Point window, click the OK button.

If you entered a relative point, the coordinates for the point are calculated based on the distance and bearing that you entered.

• To save the point and continue adding more points, click the Apply button.
• To close the Point window without saving the point data, click the Cancel button.

How to Manually Add Polygon and Polyline Points

To manually add geospatial data for a polygon or polyline:

1. Click the button in the Polygon and Polyline Points table of the Point and Polygon/Polyline List window.

The Polygon/Polyline Editor window displays.

2. Enter the identifier for the polygon or polyline in the Polygon/Polyline Shape ID field.
3. Select either the Polygon or Polyline option from the Type field.
4. Click the button.

The Point window displays.

The fields available in the Points window will depend on the coordinate reference system that you selected.

5. From the Point window, enter the point number in the Point No. field. Note that this is a required field.
6. Select the type of point that you are defining from the Point Type field.
7. Enter the local identifier for the point in the Point ID field. Note that this is a required field.
8. Do one of the following:
• To enter an absolute point, enter the coordinates in either the X/Longitude and Y/Latitude fields, or the MGRS field.

Absolute points are those points for which you know the coordinates. Relative points are those points for which you may not know the coordinates, but you do know the distance and bearing from an absolute point.

• To enter a relative point:
1. Enter the distance of the point from the absolute point in the Distance field.
2. Enter the bearing of the point relative to the absolute point in the Bearing field.
3. Select the point from which the distance and bearing are defined from the From Point list.
9. Enter a description for the point in the Point Description field.
10. Do one of the following:
• To save the point and close the Point window, click the OK button.

If you entered a relative point, the coordinates for the point are calculated based on the distance and bearing that you entered.

• To save the point and continue adding more points, click the Apply button.
• To close the Point window without saving the point data, click the Cancel button.
