Measurement

Measurement tools allow you to calculate distances and surfaces (area and perimeter). Measurements remain on the map until they are erased, allowing you to make several measurements, to print these with the map and save them in map contexts.

Distance measurement

The distance measurement tool allows you to calculate the distance between two points at a bird's eye view. The tool allows you to measure multiple segments; you then obtain the distance of each individual segment as well as the total distance of all segments. The measured distances are persistent, meaning they remain on the map until the user erases them.

1. Enable the tool clicking on .

2. Click on the desired area of the map once to get started.

3. Click on the desired area of the map to complete each segment.

4. Double-click on the map or press the spacebar to complete the measurement and display the total distance.

Surface measurement

The surface measurement tool allows you to measure areas and perimeters by tracing a polygon on the map. The measurements are persistent, meaning they remain on the map until the user erases them.

1. Enable the tool clicking on .
2. Click on the desired area of the map once to get started.

3. Click on the desired area of the map to complete a segment; repeat if desired.

4. Double-click on the map or press the spacebar to close up the polygon, complete the measurement and display the results.

Erase measures

Measurements remain on the map until they are erased. Press to erase all of them.

Measurements can be erased one at a time by following these steps:

1. Enable measurement tool (distance or surface).

2. Press and hold the ALT key.

3. Click on the measurement you wish to erase.

Measurement tools are compatible with the snap function (refer to Snap).

To obtain the geometric properties of a map element (length, area, centroid, etc.), you can use the geometry information tool instead of the measurement tool.
