Making a raster from parcels

  1. Make a table from land use code 102
  2. Assign each 102 land use a general classification type ("luclass") and unique number ("lunum")
  3. Create a shape table of parcels with PIN
  4. Create a PARCEL_EXTR table with PIN and PRESENTUSE
  5. Join to create a table with fields
    shape, PIN, presentuse, luclass, lunum
  6. Calculate luclass="water" where MINOR="HYDR"
  7. Calculate lunum=100 where MINOR="HYDR"
  8. Convert polygon to raster, name = parcel_10m
    10 m cell = 32.808 ft
    field = lunum
  9. Calculate raster, make null values = 101
    con(isnull([parcel_10m]), 101, [parcel_10m])
