A buffer is a calculated area, a perimeter, a well defined outline around one or more existing objects.
A buffer can be saved as area or can be used to start a new well defined selection of objects.
Map 2D > Tools > … > Create Buffer
The Orbit Create Buffer wizard guides you through 5 steps to get your result :
Choose you source material, or the objects for which you wish to calculate a buffer area. This source material can be an arbitrary area defined by a Fence, the selected objects, or all objects from a model.
Determine Buffer area by entering a distance (meter), either manually or based on an object attribute (only when objects are chosen as source material).
Create buffer. Press the Create Buffer button to let Orbit calculate the buffer areas. Buffers are drawn in a transparent soft grey color.
Remark : You can now choose to end the procedure. Note that the buffers are removed when the procedure is closed.
You can choose to keep the calculated buffers in a format : as a new fence, as annotations, or export and save them as new dataset.
In this last case, you can choose to keep the original object's attributes with the buffers.
Click the execute button to output the buffer objects
In case of exporting a buffer as a new dataset:
In this last step you can choose if you wish to select objects within the buffer area:
Select objects from:
Click the select button to make the selection.
