Instructions on how to make measurements.
Select the measurement tool you wish to use by clicking on its icon. The icon changes color. The section explains the features of these tools and how to use them.
Check the Snap box to enable the snap tool. The section provides details on this feature.
Select the layer to which the measurements will snap.
Make your measurements. You can use the different tools; the measurements will all be added to the map, and the distances and/or areas measured will be displayed in the card of the corresponding tool. The total number of measurements made is displayed in the panel.
Several tools allow you to take measurements. They are described below.
Click on the map once to begin your measurement.
Click on the map to define the vertices of the line.
Double-click or click on the space bar to complete your measurement. The length of each segment and the total length of the line will be displayed in the map. The total distance is also displayed in the Distance card.
Repeat the measurements, as needed. The lines are displayed in the map, and the total distance of all the lines is displayed in the Distance card.
Click on the map once to begin your measurement.
Click on the map to define the vertices of the polygon.
Double-click or click on the space bar to complete your measurement. The length of each segment, perimeter, and surface of the polygon will be displayed in the map. The surface of the polygon is also displayed in the Surface card.
Repeat the measurements as needed. Polygons are displayed in the map, and the total surface of all polygons measured is displayed in the Surface card.
Click once on the map to define the center of the circular surface you intend to measure.
Slide the mouse pointer on the map to define the circle's radius.
Click on the map or press the space bar to complete the measurement. The radius, circumference, and area (or surface) of the circle are shown in the map. The surface is also displayed in the Circular surface card.
Repeat the measurements, as needed. The circles are displayed in the map, and the total surface of all measurements (circles) is displayed in the Circular surface card.
The snap function allows you to snap the pointer that determines each vertex to elements (points, vertices or line segments) of the layer you select. This makes the measurements more precise.
Check the box to activate the tool and select the layer on which the vertices of your measurements will be snapped.
As soon as you approach the pointer to a point, vertex or line segment of the selected layer, the pointer snaps to the element and you only have to click on it to establish the vertex of your measurement.
You can change the shape and location of measurements or delete them. You can only modify the shape of one measurement at a time. You can modify the location of or delete several measurements at once.
Click on Select to select the measurement you wish to modify. The button changes color.
Select the measurement you wish to modify by clicking on it. The vertices of the line, polygon or circle are displayed.
Select a vertex by clicking on it to move it. The vertex turns black.
Drag and drop the vertex to the desired position to change the shape of the measurement.
Click on the map to finish modifying the shape of the line, polygon or circle.
Click on Select in order to select the measurements you wish to move. The button changes color.
Select a measurement by clicking on it. The vertices of the measurement are displayed.
Press and hold the SHIFT key, then click on the other measurements to add them to your selection.
Drag the mouse pointer to move the measurements, and drop them at the desired location on the map.
Click on the map to unselect the measurements.
Click on Select to select the measurements you wish to delete. The button changes color.
Select a measurement by clicking on it. The vertices of the measurement are displayed.
Press and hold the SHIFT key, then click on the other measurements to add them to your selection.
Click on the Delete button, which displays the number of selected measurements in parentheses. The selected measurements are deleted.
