GEOMLIBEXPORT ERRVALUE MapInfoExportGeoreference (  const MAPPROJPARM &  projparm,
int  xyunits,
int &  MapInfoProj,
int &  MapInfoDatum,
double  MapInfoProjParm[6],
char  ProjStr[256]
) 
 

GEOMLIBEXPORT ERRVALUE MapInfoReadTabGeoreference (  const FILEPATH &  filepath,
MAPPROJPARM &  projparm,
SIMPLE_ARRAY< CTRLPOINT3 > &  points
) 
 

GEOMLIBEXPORT double ProjDistToMeters (  const MAPPROJPARM *  proj,
double  x1,
double  y1,
double  x2,
double  y2
) 
 

Compute distance in meters between two points in specified projection.

Deprecated:
Use SPATREF classes.
Returns:
Distance between points in meters. If the coordinate system is Latitude-Longitude the distance along a geodetic is returned (actual distance over curved surface).
Parameters:
proj  Projection parameters, will use GRS-1980 ellipsoid if NULL
x1  X coordinate of first point (in meters or degrees)
y1  Y coordinate of first point
x2  X coordinate of second point
y2  Y coordinate of second point

GEOMLIBEXPORT void ProjGetArcPrj (  const MAPPROJPARM &  ProjParm,
MISTRINGLIST &  PrjList
) 
 

GEOMLIBEXPORT ERRVALUE ProjGetERMapper (  const MAPPROJPARM &  projparm,
char *  ProjectionName,
char *  DatumName
) 
 

Set ER-Mapper projection and datum names from MAPPROJPARM.

Parameters:
projparm  Projection parameters
ProjectionName  ER-Mapper projection name returned, must be at least 16 characters
DatumName  ER-Mapper datum name returned, must be at least 16 characters

GEOMLIBEXPORT bool ProjSetArcPrj (  MAPPROJPARM &  ProjParm,
const MISTRINGLIST &  PrjList,
double &  xshift,
double &  yshift,
double &  scale
) 
 

GEOMLIBEXPORT ERRVALUE ProjSetERMapper (  MAPPROJPARM &  projparm,
const char *  ProjectionName,
const char *  DatumName
) 
 

Set projection parameters from ER-Mapper Projection and Datum names.

Parameters:
projparm  Projection parameters to fill in
ProjectionName  ER-Mapper projection name
DatumName  ER-Mapper datum name
