How to set Latitude and Longitude range (Vis5D topography file), make it 0 ~ 360

[劉育帆]

Dear All:

I use a "McIDAS Base Map" file and a "Vis5D topography" file
to match a netcdf file. but it get some error..

My netcdf file range : 
 Latitude : -90 ~ 90
 Longitude : 0.0 ~ 357.5

I use 

 [code] 
 Vis5DTopoForm topoAdapter = new Vis5DTopoForm();
 topoImage = topoAdapter.open(new URL(topoFile)); 

 //set Latitude and Longitude range, lonRange[0] = 0.0, lonRange[1]
= 357.5
 double lonRange[] = lonMap.getRange();
    double latRange[] = latMap.getRange();            
    lonMap.setRange(lonRange[0], lonRange[1]);
    latMap.setRange(latRange[0], latRange[1]);
    
    ............

 //topoAdapter
    FunctionType imageFunctionType = (FunctionType)
topoImage.getType();
    RealTupleType imageDomainType = imageFunctionType.getDomain();
    RealTupleType imageRangeType = (RealTupleType)
imageFunctionType.getFlatRange();                        
    ScalarMap rgbMap = new ScalarMap((RealType)
imageRangeType.getComponent(0), Display.RGB);
    display.addMap(rgbMap);

 //set Vis5D topography map range
    LinearLatLonSet origin_set =
(LinearLatLonSet)((FlatField)topoImage).getDomainSet();
 int origin_length[] = origin_set.getLengths();                       
            
 LinearLatLonSet domain_set = new LinearLatLonSet(imageDomainType,
lonRange[0], lonRange[1], origin_length[0], latRange[1], latRange[0],
origin_length[1]);
 FlatField vals_ff = new FlatField(imageFunctionType, domain_set); 
 double[][] flat_samples = ((FlatField)topoImage).getValues();
 vals_ff.setSamples(flat_samples, false);
                                    
 DataReferenceImpl imageRef = new DataReferenceImpl("ImageRef");
 imageRef.setData(vals_ff);
 [/code]
            
 I try to several ways but not get right result..

 1.Anything not to do

 2.just set Latitude and Longitude range

 3.just set Vis5D topography map range(use LinearLatLonSet)

 4.both "set Latitude and Longitude range" and "set Vis5D topography map
range(use LinearLatLonSet)"
 http://unicle.netfirms.com/visad/ex0512.JPG

 I think the default range of "Vis5D topography file" is -180 ~ 180.
 so when I want set the new range 0 ~ 360, it could be error..

 Could someone give me a direction ? thanks a lot...
