How do I populate a field in ArcMap (and Excel) with only a specific part of another field's attributes? For example: I want to populate the LATDEG field with only the degree part of a latitudinal co-ordinate and not the entire value.
you can return the floored value.
In ArcGIS (with Python parser in the field calculator)
if you have a text field:
!yourfield!.split(".") # split at the dot and take the first(=left) part
(in Excel: FLOOR ( number , 0) )
