Hi Daniele
There is no documentation at this stage.
There is the steps assuming that your image have only one band. If you have
more
bands, just repeat the steps for each of them.
* Create a Category using the constructor expecting the following informations:
- Minimum packed value
- Maximum packed value
- scale
- offset
* If there is a "nodata" value, create a Category using the constructor
expecting only the following information (without scale/offset):
- A single packed value.
* Create a SampleDimension with the list of above categories and
SI.CELSIUS unit.
* Create a GridCoverage2D with the above SampleDimension.
The GridCoverage that you get is ViewType.PACKED. Invoking
GridCoverage2D.evaluate(position) will give you the packed values.
In order to get geophysics values, invokes the following:
coverage = GridCoverage2D.view(ViewType.GEOPHYSICS);
Invoking evaluate(position) on the coverage returned by the above will give you
the temperature in °C, with "nodata" values replaced by NaN.
