 FIELD DEFINITIONS  




 LatLoc
     - 
      The UDF location of the latitude data defined
         under this LatLongstructure.  This can be Sensor data, 
         Ancillary data or sCan data. (PIDF Image LatLong 
         sub-structure 
         KEYWORD: lat_loc)
 

 LongLoc
     - 
      The UDF location of the longitude data defined
         under this LatLongstructure.  This can be Sensor data, 
         Ancillary data or sCan data. (PIDF Image LatLong 
         sub-structure 
         KEYWORD: lat_loc)
 

 LatNum
     - 
      When the latitude information is stored as
         sensor data then this is the UDF sensor number.  When the 
         latitude information is stored as ancillary data then this is 
         the UDF ancillary data set number.  It has no meaning if the
         latitude is stored as scan data.  (PIDF Image LatLong sub-structure 
         KEYWORD: lat_num)
 

 LongNum
     - 
      When the longitude information is stored as
         sensor data then this is the UDF sensor number.  When the 
         longitude information is stored as ancillary data then this is 
         the UDF ancillary data set number.  It has no meaning if the
         longitude is stored as scan data.  (PIDF Image LatLong sub-structure 
         KEYWORD: long_num)
 

 LatUnit
     - 
      The VIDF unit definition block number which converts
         the raw UDF latitude  data to degrees.  (PIDF Image LatLong 
         sub-structure 
        KEYWORD: lat_unit)
 

 LongUnit
     - 
      The VIDF unit definition block number which converts
         the raw UDF longitude  data to degrees.  (PIDF Image LatLong 
         sub-structure 
         KEYWORD: long_unit)
 

 LatDef
     - 
     The location of the latitude definition within
         pixel outline definition.  
         (PIDF Image LatLong sub-structure 
         KEYWORD: lat_def)
 

 LongDef
     - 
     The location of the longitude definition within
         pixel outline definition.  
         (PIDF Image LatLong sub-structure 
         KEYWORD: long_def)
 






  DESCRIPTION  
 This structure holds one instance of the PIDF LatLong block 
definition.  Its contents are filled in by the 
ReadPidf() routine.  The contents of this structure are held within
the PIDF Image structure under the 
LatLong field.
