Typedef Documentation

typedef boost::shared_ptr<FeltGridDefinition> felt::FeltGridDefinitionPtr

typedef short int felt::word

A felt block "word" - 2 bytes.


Function Documentation

std::ostream& felt::contentSummary ( std::ostream out,
const FeltGridDefinition &  grid 
)

template<typename T>
T felt::get ( word  w  )  [inline]

boost::array<float, 6> felt::gridParameters ( int  gridType,
int  xNum,
int  yNum,
int  a,
int  b,
int  c,
int  d,
const std::vector< short int > &  extraData 
)

retrieve the 6 gridparameters from the felt-data

Parameters:
gridType id of the grid, (header[8] < 1000) ? header[8] : (int) header[8] / 1000
xNum number of points in x-direction, header[9]
yNum number of points in x-direction, header[10]
a used for different depending on gridType, header[14]
b used for different depending on gridType, header[15]
c used for different depending on gridType, header[16]
d used for different depending on gridType, header[17]
extraData data at the end of the data-region, used for high resolution information (header[8] < 1000) ? 0 : header[8] % 1000

std::string felt::gridParametersToProjDefinition ( int  gridType,
const boost::array< float, 6 > &  gridPars 
)

convert the libmi-gridparameters to proj4 strings

Parameters:
gridType type defining the projection (1..6)
gridPars array containing libmi's six gridparameters
Returns:
proj.4 string

bool felt::isUndefined ( word  w  )  [inline]

Is the given word a "missing" value? This means that there exist no valid data for the given point

boost::posix_time::ptime felt::parseTime ( const word *  data  ) 

boost::posix_time::ptime felt::parseTimeNoThrow ( const word *  data  ) 


Variable Documentation

const size_t felt::blockSize = blockWords * sizeof(word)

const size_t felt::blockWords = 1024

const double felt::EARTH_RADIUS = 6371000.

earth-radius in m, taken from libmi rearth.f

const double felt::PI = M_PI

mathematical pi
