Class AreaFile3

java.lang.Object

ucar.nc2.iosp.adde.AreaFile3

public class AreaFile3
extends Object

AreaFile interface with McIDAS 'area' file format image data. The data is made into an ucar.ma2.Array object. This will allow 'area' format data to be read from disk; the navigation block is made available (see GVARnav for example). This implementation does not do calibration (other than accounting for its presence in the data). Also, the 'valcode' is not checked on each line.
