Method Detail

getType

RadialDatasetSweep.Type getType()

Returns:

the type of the Sweep

getRadialNumber

int getRadialNumber()

Returns:

the number of radials for this Sweep

getGateNumber

int getGateNumber()

Returns:

the number of gates for all radials

getBeamWidth

float getBeamWidth()

Returns:

the beam width for all radials, in degrees

getNyquistFrequency

float getNyquistFrequency()

Returns:

the Nyquist Frequency for all radials

getRangeToFirstGate

float getRangeToFirstGate()

Get the radial distance from origin to the start of the first data gate. The radial distance to the ith gate = getRangeToFirstGate() + getGateSize() * i

Returns:

distance to first gate in meters, for all radials

getGateSize

float getGateSize()

Get the radial length of each data gate. The radial distance to the ith gate = getRangeToFirstGate() + getGateSize() * i

Returns:

gate size in meters, for all radials

readData

getMeanElevation

float getMeanElevation()

Returns:

the average elevation of all the radials in the sweep, in degrees. Only valid if getType() == TYPE_
