I am stringing together a series of raster calculations in the QGIS process modeler in order to calculate a surface temperature dataset from Landsat and weather data.
When I use the output from multiple prior algorithms in the model as the input for a raster calculation, the result is a blank grid (-1.79769e+308 to 1.79769e+308). Calculations performed with input parameter bands work as expected.
This issues appears to have been addressed in this QGIS bug report.
However I've updated my install and the problem persists. Can anyone advise on this? I'd rather not split my model into several smaller models.
