Spatial operations are performed on one or more selected elements.
A spatial operation results in a new geometry added to the Annotations layer.
When you perform spatial operations on editable elements, you can press and hold down the CTRL key to keep only the results of the operation, i.e. automatically deleting the editable elements that were selected.
Creates a buffer zone around the selected map elements.
Select the desired elements and press.
You must then specify the size of the buffer, i.e. the maximum distance between any point of the buffer and the selected elements. The size can be negative, in which case the buffer can be smaller than the selected elements. The size of the buffer is indicated in the map's unit of distance.
Keep Generate a buffer for each selected element checked if you want this type of buffer.
Specify the precision of the buffer arcs, in degrees.
Press OK. The example shows a 100 m buffer around each park in a city.
Uncheck Generate a buffer for each selected element if you wish a single buffer to be generated for the set of selected elements.
Specify the precision of the buffer arcs, in degrees.
Press OK. The example shows a 100 m buffer around parks in a city.
Creates a new element by uniting the selected elements.
Creates a new element that is the intersection of the selected elements.
Creates a new map element that is the difference between the first selected element and the others. In other words, all elements are subtracted from the element that was selected first.
Creates new elements resulting from the intersection of two polygons.
Creates new elements resulting from the splitting of a polygon using a line.
Creates a new element that is the smallest convex polygon that entirely covers the selected elements.
