7.6.1. Buffer(s)

In QGIS, the Buffer tool can be accessed in the following way (see section 6.5.5. for a description of the tool):

  1. Go to Vector.
  2. Select Geoprocessing Tools.
  3. Choose Buffer.
  4. Select a realistic buffer value for honey bees (e.g. 2,000 meters).
  5. Leave the dissolve option blank (otherwise all buffers will be aggregated to one single feature without the different attributes, see Fig. 95).
  6. Specify the path and name for the destination file.
  7. Click OK.
  8. Click YES to confirm loading the newly created vector file to the QGIS project.

One should consider the use of the buffer function may lead to topologically incorrect vector files, e.g. when the distances between the features of origin are closer than the double buffer radius, leading to overlaps between different features. The circle polygons created in this step are visible in Fig. 99.
