Create Buffer
What does it do ?
Use the Buffer technique to find objects that are located within a distance from other objects, and save the buffer area's.
Overview
The Orbit GIS Buffer tool is a 5 step procedure. Launch the procedure by selecting the menu option Tool → Buffer… .
Step 1 : Source
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.
In the first option, you can open the Fence toolbar to create or change the fence for us in this procedure.
In the last option, select the Model from which you wish to use all objects. Note that this procedure can take quite some time depending on the amount of objects in the model.
Step 2 : Distance
Determine Buffer area by entering a distance, either manually or based on an object attribute (only when objects are chosen as source material. You can optionally specify to use multiple rings (each with the same distance).
Step 3 : Create
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.
Step 4 : Output
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.
Step 5 : Select
In this last step you can choose if you wish to select objects within the buffer area. Select the dataset from which you wish to select objects. End the procedure to select the objects and view the selected objects in the Object Inspector window.
