getColumnNumber()

ossim_int32 ossimDemProfile::getColumnNumber

(

)

const

Column identification number. This is the profile sequence number.

getElevations()

ossimDemElevationVector const & ossimDemProfile::getElevations

(

)

const

Elevation values. From the DEM standard: "A value in this array would be multiplied by the spatial resolution value and added to the elevation of the local elevation datum for the element profile to obtain the elevation for the point."

getLocalDatumElevation()

double ossimDemProfile::getLocalDatumElevation

(

)

const

Elevation of local datum for the profile. Value is in units of measure given by the Elevation Units field found in the DEM header.

(

)

const

Maximum elevation for this profile.

Definition at line 93 of file ossimDemProfile.cpp.

References _maxElev.

{
   return _maxElev;
}

getMinimumElev()

double ossimDemProfile::getMinimumElev

(

)

const

Minimum elevation for this profile.

Definition at line 87 of file ossimDemProfile.cpp.

(

)

const

Location (in ground planimetric coordinates) of the first
