Hi Jeff,

Testing the Contextual factors they are in line with the thresholds but when it comes to final score for Contextual aggregation factors, the value it's not averaged.

Example tested:

WD is 83.8 and the raster has the value 4.19 (correct)
RF is 100 for Pay and 40 for Parenthood and the raster gets after averaging the value 3.5 (correct)
FI is 75 an the raster value is 3.75 (correct)

The aggregated raster which has the same weights and is a straightforward average for all 3 factors is 2.56 (incorrect) and should be 3.81.

Please double-check the values and ensure they are being averaged correctly.

Hi @dragosgontariu

Thanks for picking up that. I'll take a look at it and fix it.

Contextual_score succeed with some Python error. Although the Contextual_score.tif exist but the value is incorrect, then it means the script failed to generate the correct value and save as a file.
