With the measurement tools, you can:

  • Measure the length of a straight line
  • Measure the length of a path composed of multiple lines
  • Draw a polygon on the map and measure its area and the length of its sides
  • Draw a circle on the map and measure its area and radius

You can access these measurement tools from the toolbar:


This guide includes the following sections:


Note: The MapBrowser's measurement tools use appropriate local representations of the Earth's surface and are typically accurate to +/- 15 cm for distances up to 200 m. 

Line



To use the Line feature:

  1. Click the line tool icon to open the Line panel.
  2. Position the cursor at the location you want to start your measurement and click once - this drops a marker to show the starting point. While you're drawing the line, you can still click and drag the map to pan.
  3. Move the cursor to another location and click again to drop another marker at the end of the distance you want to measure. Note that you can measure as many 2-point distances as you like, but they are not cumulative. The bearing will update automatically when the line is completed.
  4. You can choose to display the distance in different units, including metric or imperial.
  5. You can choose to Show inline measurements by clicking the corresponding checkbox - this will display the value on the line itself.
  6. When you are done, just close the toolbox and resume exploring the map. The line you have measured will remain visible.
  7. To review a distance you had measured, simply click on the measured line and the measurement dialog will reopen, showing the length of the selected line.
  8. You can click and drag the starting or ending control points to reposition them – the measurement will update automatically.
  9. To remove the selected measurement object click Delete or the trash can in the panel. 
  10. To remove all measurement objects, click Clear.

Path/Multi-line

To use the Path feature:

  1. Click the zigzag path tool icon to open the Path panel.
  2. Position the cursor at the location you want to start your measurement and click once - this drops a marker to show the starting point. While you're drawing the path, you can still click and drag the map to pan.
  3. Move the cursor to another location and click again to drop a waypoint. Continue doing so until you have created the entire path you want to measure, and double-click your last point.
  4. You can choose to display the distance in different units, including metric or imperial.
  5. You can choose to Show inline measurements by clicking the corresponding checkbox - this will display values on each leg of the path itself.
  6. When you are done, just close the toolbox and resume exploring the map. Paths you have measured remain visible.
  7. To review a distance you had measured, simply click on the measured path and the measurement dialog will reopen, showing the length of the selected path.
  8. You can click and drag any control point to reposition it – the measurement will update automatically.
  9. To remove the selected measurement object click Delete or the trash can in the panel. 
  10. To remove all measurement objects, click Clear.

Area


To use the Area feature:

  1. Click the polygon-shaped tool icon to open the Area panel.
  2. Position the cursor at the location you want to start your measurement and click once - this drops a marker to show the starting point. While you're drawing the area, you can still click and drag the map to pan.
  3. Move the cursor to another location and click again to drop a waypoint. Continue doing so until you have created the entire area you want to measure, and double-click your last point. The area and perimeter of the region will be displayed.
  4. You can choose to display the area and perimeter in different units, including metric or imperial.
  5. You can choose to Show inline measurements by clicking the corresponding checkbox - this will display values on each leg of the polygon itself as well as in the center of the area.
  6. When you are done, just close the toolbox and resume exploring the map. The polygon will remain visible.
  7. To review a distance you had measured, simply click on the measured path and the measurement dialog will reopen, showing the length of the selected path.
  8. You can click and drag any control point to reposition it – the measurement will update automatically.
  9. To remove the selected measurement object click Delete or the trash can in the panel. 
  10. To remove all measurement objects, click Clear.

Circle/Radius


To use the Measure Circle feature:

  1. Click the circle tool icon to open the Measure Circle panel.
  2. Position the cursor at the location you want to start your measurement and click once - this drops a circle of a default size.
  3. There are four control points along the edges of the circle and one in the middle. Any of the four outer points can be clicked and dragged to expand or shrink the circle. The middle point can be clicked and dragged to move the circle. The measurement will update automatically.
  4. You can choose to display the distance in different units, including metric or imperial.
  5. You can choose to Show inline measurements by clicking the corresponding checkbox - this will display values in the center of the circle itself.
  6. Note that only one measurement circle can exist at a time.
  7. When you are done, just close the toolbox and resume exploring the map. The circle you have measured remains visible.
  8. To review a circle you had measured, simply click on the measured circle and the measurement dialog will reopen, showing the length of the selected path.
  9. To remove the circle, click the trash can in the panel. 

AutoTrack

The AutoTrack tool can be found in the Line, Path, and Area tools. It is disabled unless there is a line or path placed on the map. If a path or line is present, pressing the play button will zoom to one end of the path/shape and start panning along the length of the path.

The speed and direction of the movement can be adjusted using the corresponding controls. Movement can be paused and resumed from the same position using the pause button. If you press the stop button, when play is resumed it will begin at the start of the path.
