Angle-Angle Intersection Simulation Instructions

This page launches a Java applet simulation of the Angle - Angle Intersection process and requires your browser to be 'Java Enabled'. If your browser is not already Java enabled, please edit your browser preferences now.

At the bottom of this page is a button which will launch the simulation. Be patient, it may take a while to load. If this button isn't showing your browser may not be Java Enabled.

The positions of point A and point B are known. Point A and point B define a baseline from the ends of which angles are measured to another station whose position is unknown. From the coordinates of the baseline stations and the measured angles, the coordinates of the unknown station can be calculated.

The toolbar of the Angle-Angle Simulation contains two icons as listed below:

Select

This tool can be used to movepoint A or point B to a new position. Click on the point you wish to move, when selected a black circle is drawn around it, and then click on the screen in the new position you wish to move the point to.

Measure

Select this tool and then click anywhere on the screen to locate the unknown station position whose coordinates are to be calculated. Once you have selected a position for your station the simulation measures the angles from the two end points to the station. The angles will be shown in the text fields below.

Once the measurements have been taken push the 'Calculate' button the find the coordinates of the unknown station and to show the associated error ellipse. The closer this red ellipse appears to a true circle, the more precise you can assume the results of your calculations to be.

Note: The error ellipse will only be drawn if the server side application is running. If it is not shown after you press the Calculation button, please email the site maintainer.
