質問 2:
A GIS analyst is using the Raster Calculator to determine the best location to start a coffee tree farm. The soil should be deep sandy loam (represented by class code 5 in raster) or fertile volcanic red earth (class code 12).
Temperatures should remain between 17.8 to 21.1 degrees Celsius (64 and 70 degrees Fahrenheit), and the area should get at least 60 inches (1.52 meters) of rain per year.
Which expression should be used to produce suitable areas?
A. ("Temperature" <= 70) & ("Temperature">=64) & ("SoilType"=5) | (SoilType=12) &("Precipitation"
>=60)
B. (Precipitation>='60') & (Temperature <= '70') & (Temperature>='64') &((SoilType='5') & (SoilType='12'))
C. ("Precipitation">=60) &(("SoilType"=5)|(SoilType=12)) &("Temperature" <= 70) &("Temperature"
>=64)
