88    1 character population assessment:  
         R = rural: <10,000 population), 
         S = small town (10,000-50,000), 
         U = urban area (>50,000)
89-93 population of the small town or urban area (multiplied  by 1,000).  
        If rural, no analysis:  -9.
94-95 topography around the station:  
        FL flat, HI hilly, MT mountain top; MV mountainous valley
96-97 vegetation near the station:
         MA marsh; FO forested; IC ice; DE desert; CL clear or open;
         not all stations have this information in which case: xx.
98-99 station location based on 3 specific criteria:  
         Is the station on an island smaller than 100 km**2 or
            narrower than 10 km in width at the point of the station?  IS; 
         Is the station is within 30 km from the coast?  CO;
         Is the station is next to a large (> 25 km**2) lake?  LA;
         A station may be all three but only labeled with one with
             the priority IS, CO, then LA.  If none of the above: no.
100-101 if the station is CO, is the distance in km to the coast.
          If station is not coastal:  -9.
102     A if the station is at an airport; otherwise x
103-104 distance in km from the airport to its associated
          small town or urban center (not relevant for rural airports
          or non airport stations in which case: -9)
105-120 16 character gridded vegetation for the 0.5x0.5 degree grid point closest
          to the station from a gridded vegetation data base.
