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()

readAttributeDouble

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

Read an attribute as a double.

Parameters:

atts - the attribute container

attname - name of variable

defValue - default value if attribute is not found

Returns:

attribute value as a double, else NaN if not found

addParameter

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

Add a Parameter to a CoordinateTransform. Make sure that the variable exists.

Parameters:

rs - the CoordinateTransform

paramName - the parameter name

ds - dataset

varNameEscaped - escaped variable name

Returns:

true if success, false is failed
