This section refers to measurement tools for vertical imagery. Please refer to Measure Oblique Imagery for other height, width, and area tools.


This guide explains how to use the tools in a web browser. For measuring on tablet devices see Measure on Tablet Device

All the measurements and their related settings can also be saved in your MapBrowser Projects. Read more about Projects here: Organise and Save Content in MapBrowser.

Note: 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 Tool

Draw a simple line on the map

  1. Click the Line button.
  2. Click the start point of the line.
  3. Double-click to complete the line.

*  Use the Show options (see Display units on a map), to hide or display these features on the map

** If a dimension on the map is too small to display at the current zoom level, you'll see "..." instead. Zoom in to see the measurement.


Change line measurements

You can drag a line's endpoint to change its length and bearing.

You can also edit directly in Inspector Panel. Here's how:

With the line selected, in the Inspector Panel you can enter a new value for:

  • Line length
  • Bearing - this is the absolute geometrical direction


  • Rotation - is relative to the line's bounding box

Multi-path line

Draw a multi-path line on the map

  1. Click the Line button.
  2. Click each vertex of each line segment.
  3. Double-click to complete the line.

Change path rotation

With the multi-line selected, in the Inspector Panel you can enter a new value for rotation.  Rotation is relative to the line's bounding box, just as it is for a line (see above).



Edit a point (move point, add point)

To move a point:

  1. Click the point and drag. Then drop to where you want it.




To add a point:

  1. Click anywhere on the line or line segment.
  2. A new point appears midway along the line or line segment.
  3. You can now click and drag that point to where you need it.


NOTE: You can only add a point at the midpoint of a line or segment. After you create the point, you can drag it to where you want it.


To delete a point:

  1. Double-click the point.

Polygon Tool

Draw a polygon on the map

  1. Click the Polygon button.
  2. Draw out the area by clicking each vertex of your area.
  3. Double-click the last vertex to close out the area.

Change polygon rotation

With the polygon selected, in the Inspector Panel you can enter a new value for rotation.  Rotation is relative to the line's bounding box, just as it is for a line (see above).




Circle

Draw a circle on the map

  1. Click the Circle button.
  2. Click onto the map roughly where the centre of the circle is. Don't worry if it's not exact, you can move the circle later.
  3. Click onto the point so that you see a dotted box around it.
  4. Now drag out the circle until it is the size you want.

Move the circle

  1. If you need to move the circle, click on it so that you see the surrounding box .
  2. Drag the circle and drop it at its new location.

Resize the circle - on the map

  1. If you need to resize the circle, click on it so that you see the surrounding box.
  2. Click anywhere on the circle's perimeter.
  3. Drag the dot on the perimeter and release it when the circle is the desired size.

Resize the circle – from Inspector Panel

Simply enter a new value for the radius or diameter. The circle resizes about its centre.
