Which statement represents an example of spatial filtering?

• A. Filtering out all businesses in a particular industry using the text attribute 'Industry'
• B. Filtering out forest stands within 50 kilometers of a road using the Bufferer and the PointOnAreaOverlayer
• C. Filtering out natural gas wells that had casing failures within the last year using the date attribute 'LastCasingFailureDate'
• D. Filtering out website visitor sessions that resulted in a purchase using the boolean attribute 'SessionPurchase'

Answer: (B)

Spatial filtering means selecting features based on where they are or how they relate spatially to other features, not just on attribute values. In this example, you’re deciding which forest stands lie within a distance of road infrastructure, which is a distance-based spatial relationship. By creating a 50-kilometer buffer around roads with the Bufferer and then using a spatial overlay to see which forest stands fall inside that buffered area (the PointOnAreaOverlayer step helps evaluate that intersection), you’re filtering based on location and proximity. The other options rely on attribute data alone (text, date, or boolean fields) and do not involve the geometry or distance relationships that define spatial filtering.
