Data type conversion
From AWF-Wiki
We may change the data type (or radiometric resolution) of a raster layer.
- Click the Add raster layer and select a single band or a multiband file dop/DOP_VI.tif. This is multiband file wit three different spectral indices created by Orfeo Toolbox --> Feature Extraction --> Radiometric Indices) with the data type Float (Check the Raster metadata). We would like to convert to data type Byte - eight bit unsigned integer, value range 0 to 255.
- Click Open.
- In processing toolbar, type dynamic into the search field to find the Orfeo Toolbox --> Image Manipulation --> DynamicConvert) tool.
- Open with a double click. Specify the input and a new output file name as shown in the screenshot.
- Set High cut quantil and Low cut quantile to 0
- Click Advanced parameters and define Output pixel type uint8.
- Click Run.
The output Image raster is now recoded and saved to unsigned eight bit.
