Method Detail

getFalseEastingScaleFactor

public static double getFalseEastingScaleFactor(NetcdfDataset ds,
                                                AttributeContainer ctv)

getGeoCoordinateUnits

public static String getGeoCoordinateUnits(NetcdfDataset ds,
                                           AttributeContainer ctv)

getFalseEastingScaleFactor

public static double getFalseEastingScaleFactor(String geoCoordinateUnits)

setErrorBuffer

public void setErrorBuffer(Formatter errBuffer)

getTransformName

public abstract String getTransformName()

readStandardParams

protected void readStandardParams(AttributeContainer ctv,
                                  String units)

readAttributeDouble

protected double readAttributeDouble(AttributeContainer v,
                                     String attname,
                                     double defValue)

Read a variable attribute as a double.

Parameters:

v - the variable

attname - name of variable

defValue - default value if attribute is not found

Returns:

attribute value as a double, else NaN if not found

readAttributeDouble2

protected double[] readAttributeDouble2(Attribute att)

Read an attribute as double[2]. If only one value, make second same as first.

Parameters:

att - the attribute. May be numeric or String.

Returns:

attribute value as a double[2]

addParameter

protected boolean addParameter(CoordinateTransform rs,
                               String paramName,
                               NetcdfFile ds,
                               String varNameEscaped)

Add a Parameter to a CoordinateTransform. Make sure that the variable exists. If readData is true, read the data and use it as the value of the parameter, otherwise use the variable name as the value of the parameter.

Parameters:

rs - the CoordinateTransform

paramName - the parameter name

ds - dataset

varNameEscaped - escaped variable name

Returns:

true if success, false is failed

getFormula

protected String getFormula(AttributeContainer ctv)

parseFormula

public String[] parseFormula(String formula_terms,
                             String termString)

getEarthRadiusInKm

protected double getEarthRadiusInKm(AttributeContainer ctv)

Get the earth radius in km from the attribute "earth_radius". Normally this is in meters, convert to km if its > 10,000. Use Earth.getRadius() as default.

Parameters:

ctv - coord transform variable

Returns:

earth radius in km
