Q. Why are there odd lines in the canopy fuel data?
Note that these lines exist in the Existing Vegetation Type layer as well. These lines result form radiometric oddities in the satellite imagery used to create these layers. This phenomenon generally occurs on the seam where two satellite overpasses from different dates were mosaicked to produce a seamless coverage of each zone. Since satellite imagery serves as a predictor of canopy base height (CBH) and canopy bulk density (CBD), the lines are "stamped" onto the resulting CBH and CBD layers.
