How to make measurements


Distances and areas can be measured on your map in the units of your choice. In 3D mode you can create an elevation profile along a specified line.

How to measure distances and areas


Distances and areas are measured quickly on-screen using the Measurement tools. You can also make measurements for later use by using the Drawing tools.

Distance and area can be measured by using the Measurement and Draw places tools. The Measurement tool provides a quick method for obtaining measurements. The Places tool allows you to retain measurements to save into your map for later use or for printing.

How to measure a line


The measurement tool provides a quick way of measuring features on the map. It will display a temporary measurement, visible until the tool is deselected or a new measurement is drawn.

To measure a line:

  1. Zoom to a location on the map you wish to measure
  2. Click Tools → Measurement → Measure line
  3. Adjust the units if required

  4. measure line

  5. Click on the map to start drawing a line. Note that a length value will appear over your line, and update dynamically as you draw. Note also that segment length, overall length, and bearing appear in the bottom left corner of the map.

Click again at each bend in the line to create a vertex

Double click to finish the line

Review the measurement result on the screen

If the line needs adjustment, the individual vertices can be picked up and moved. Note that no new vertices can be added, nor can the whole object be picked up and moved.

To remove the measurement from the map, click New Measurement.

How to measure an area


Zoom to a location on the map you wish to measure.

Click Tools → Measurement → Measure area

Adjust the units if required

measure area

Click on the map to start drawing an area line. Note that an area value will appear over your polygon, and update dynamically as you draw. Note also that area and perimeter appear in the bottom left corner of the map

Click again at each corner of your area to create a vertex

Double click to finish the area measurement.

If the area needs adjustment, the individual vertices can be picked up and moved. Note that no new vertices can be added, nor can the whole object be picked up and moved.

To remove the measurement from the map, click New Measurement

How to draw Places


Sometimes it may be necessary to create a measurement that can be stored for later use, such as in a printed map. This can be done using the Draw places tools.

Zoom to a location on the map where you wish to add measurements

Click Tools → Draw Places → Draw (choose point, rectangle, line, polygon, or circle)

draw places available shapes

Draw your selected shape, noting the dimensions dynamically updating at the bottom left of the maps as the shape is drawn.

Click Places → Select your new shape → Click down arrow (chevron) → Attributes

Review the dimensions in the attribute list. These will vary depending on the type of object drawn.

If you wish to add a label with your measurement to the map, find the required measurement (e.g. area or length) in the attributes. Highlight → Right click → Copy

measure length and copy

Go to Name and paste the copied measurement.

Click Add Label to Map checkbox. Adjust the settings as desired.

Confirm area measurement is visible on the map.

How to create an elevation profile


You can show the elevation profile along a drawn line, using the terrain available in 3D view (on 3D compatible devices).

To display the terrain profile, first ensure you are in 3D mode by clicking on the 3D icon at the bottom left of the map.

change 3d

Then Select the Draw line tool and draw a line on the map at the required location for your profile.

Your newly created line is stored in Places. Click the Places button to reveal the Places panel, then click the down arrow next to your new line (called My Place 1 in this example). Then click Show profile using surface terrain.
