Which attribute is exposed to view Elevation in Table View after using PointOnRasterValueExtractor?

• A. Elevation
• B. _band{}.value
• C. RasterValue
• D. BandValue

Answer: (B)

When you sample a raster at a point, the value from the raster is stored as an attribute that reflects the band it came from. In Table View, these attributes follow the pattern _band{bandNumber}.value, where the band number corresponds to the raster band. For a single-band DEM, you’ll see the elevation data under _band1.value. So the attribute that exposes the Elevation is the band value attribute itself, written as _band{bandNumber}.value. The other names don’t match the actual attribute created by PointOnRasterValueExtractor by default. If needed, you can rename that attribute to Elevation for clarity after extraction.
