GEOMLIBEXPORT MISTRING ConvertDegsToString (  double  value, DEGTOSTRFLAGS  flags )

Convert Latitude or Longitude value to MISTRING. Returns: MISTRING containing converted value. See also: ConvLatLonToString, ConvertStringToDegs Parameters: value  Value to convert in degrees flags  Flags defining format

GEOMLIBEXPORT char* ConvertDegsToString (  char *  string, double  value, DEGTOSTRFLAGS  flags )

Convert Latitude or Longitude value to char* string. Returns: Pointer to string See also: ConvLatLonToString, ConvertStringToDegs Parameters: string  String to hold result value  Value to convert in degrees flags  Flags defining format

GEOMLIBEXPORT bool ConvertStringToDegs (  const char *  string, double *  value )

Convert Latitude or Longitude string to decimal degrees. Returns: true if successful, false if not This function automatically recognizes the following formats: D ddd mm ss.sss D indicates direction (N, S, E or W) D ddd mm.mmmm and can be anywhere in the string D ddd.ddddd [-]ddd mm ss.sss Sign (+ or -) is optional [-]ddd mm.mmmm Negative values indicate West and South [-]ddd.ddddd Do not type brackets [] See also: ConvertStringToLatLon, ConvertDegsToString

GEOMLIBEXPORT void ConvLatLonToString (  double  degrees, char *  string, DMSTYPE  desttype, CONVDMSFLAGS  flags )

Convert Latitude/Longitude value to string. See also: ConvertDegsToString, ConvStringToLatLon Parameters: degrees  Value to convert string  String to hold result desttype  Destination format flags  CONVDMS_OUT_...

double ConvLatLonValue (  double  value, DMSTYPE  srctype )  [inline]

Convert double-precision value to decimal degrees. Returns: Converted value in degrees. Parameters: value  Value to convert srctype  Source format Definition at line 229 of file latlonfm.h.

GEOMLIBEXPORT double ConvLatLonValue (  const void *  srcbuf, DMSTYPE  srctype, void *  destbuf, DMSTYPE  desttype, CONVDMSFLAGS  flags )

Convert value to decimal degrees and/or another LatLon format. Returns: Converted value in degrees. Parameters: srcbuf  Pointer to source value, flags determine data type srctype  Source format destbuf  Pointer to destination location, NULL if not needed desttype  Destination format flags  Flags for input and output type

GEOMLIBEXPORT double ConvStringToLatLon (  const char *  string, DMSTYPE  srctype, CONVDMSFLAGS  flags = CONVDMSFLAG_None )

Convert string to decimal degrees. Returns: Converted value in degrees. See also: ConvertStringToDegs, ConvLatLonToString Parameters: string  String to convert srctype  String format flags  None presently used

GEOMLIBEXPORT const char** GetLatLonNames (  void   )

Retrieve list of built-in latitude-longitude string formats. Returns: NULL-terminated array of strings containing format names.

GEOMLIBEXPORT DMSTYPE GetLatLonType (  int  index  )

Get latitude-longitude format conversion type for given index. See also: ConvLatLonValue, ConvLatLonToString, ConvStringToLatLon
