I’m reading a geotiff file with embedded scaling and offset, snippet from gdalinfo:
Band 1 Block=1024x1024 Type=Byte, ColorInterp=Red
NoData Value=255
Overviews: 6000x6000, 3000x3000, 1500x1500, 750x750
Offset: -1, Scale:0.008
Band 2 Block=1024x1024 Type=Byte, ColorInterp=Green
NoData Value=255
Overviews: 6000x6000, 3000x3000, 1500x1500, 750x750
Offset: -1, Scale:0.008
Band 3 Block=1024x1024 Type=Byte, ColorInterp=Blue
NoData Value=255
Overviews: 6000x6000, 3000x3000, 1500x1500, 750x750
Offset: -1, Scale:0.008
When working with the data in FME just the the 8-bit value is shown (0-255) when I was expecting values between -1 and 1. In my particular use case the scaling is constant and I can just apply a correction, but I was wondering if there is a setting I’m missing to have FME apply the scaling/offset automatically.
