1 Note to User: URBAN FIA Field Guide 6.0 is based on the National CORE Field Guide, Version
6.0
. Data elements are national CORE unless indicated as follows:
National CORE data elements that end in “+U” (e.g., x.x+U) have had values ,codes , or text
added,
changed , or adjusted from the CORE program . Any additional URBAN FIA text for a
national CORE data element is hi
-lighted or shown as an "Urban Note" .
All URBAN FIA data elements end in “U” (e.g., x.xU). The text for an URBAN FIA data
element is not hi-
lighted and doe s not have a corresponding variable in CORE . *
National CORE data elements retain their national CORE field guide data element/variable
number but may not retain the
ir national CORE field guide location or sequence within the guide .
