Cadastral Tools

Line from Points Tool

This tool calculates the bearing and distance between the coordinates of two selected points. Read more...

Basic Use

1. click to start the tool
2. Select two points (bearing will be from first to second).
3. Ctrl+Shift+ click to calculate

Results are shown in the Tool Results window, and graphics on the map.

Keep it simple! Complex fabrics can have many points, and selection is sometimes difficult. Use the Fabric controls to show only the plan or plans needed.

Selecting Points

For complex situations, consider the following:

• Order of selection determines bearing.
• Points are shared between plans in the fabric.
• Limit points shown using the Fabric Control.
• Selection of points is often easiest using click-drag.

Selection Operations

1. Select first point with mouse click
2. You can also use a selection box (click and drag).
3. Select second point with Shift+ click
4. If you make a mistake, deselect a point by Ctrl+ click
5. You can use a selection box (click and drag) to select one or both points, or with Ctrl and Shift combinations.

Details

Here are a few points about how it works:

1. Distance is calculated from grid coordinates, converted to ground.
2. Calculation uses a point scaling factor based on location of coordinates. Example: psf = 1.00018917

Warning! Calculations are made from the point coordinates. Accuracy of calculations depends on the methods used to coordinate the points in the fabric.

The Closing Line Tool uses the recorded bearings and distances of a traverse to calculate the final closing line, and also compares it to a calculation using the endpoint coordinates.
