Making a raster from parcels
- Make a table from land use code 102
- Assign each 102 land use a general classification type ("luclass") and unique number ("lunum")
- Create a shape table of parcels with PIN
- Create a PARCEL_EXTR table with PIN and PRESENTUSE
- Join to create a table with fields
- shape, PIN, presentuse, luclass, lunum
- Calculate luclass="water" where MINOR="HYDR"
- Calculate lunum=100 where MINOR="HYDR"
- Calculate lunum=200 where lunum is null
- Convert polygon to raster, name = parcel_grid_0 (intermediate)
- 10 m cell = 32.808 ft
- field = lunum
- Calculate raster, make null values = 300
- con(isnull([parcel_10m]), 300, [parcel_10m])
- Make permanent, "parcel_10m"
Constants:
- 1 m = 3.2808 ft
- 10 m = 32.808 ft
- 100 m = 328.08 ft
