Question

Raster Calculator not calculating all files that were input

In my workbench I am taking points, buffering them, and using those buffered areas to clip small portions of a raster mosaic.  After clipping I then run a raster calculator on each of those points  to find the sum, mean, min, max range, etc and create an excel file with all the values calculated and collected.

 

My workbench runs successfully, however in several of my datapoints I get empty rows with no stats being calculated.  When I check the area in ArcGIS Pro there aren’t any null values in those areas and it runs without any issue.  I have tried using RasterBandCoercer to change any null values to 0, rasterbandnodataremover, and nullattribute mapper to help deal with these issues but none of them give me results that I can actually use without skewing the data and giving me invalid results.

 

Does anyone have any suggestions or ideas on how I can fix this issue?

 

Currently running FME(R) 2024.0.1.0

 

Thanks!

Are any of your buffered areas overlapping?

no, they’re all spaced quite far apart, the buffer’s themselves are quite small, from 0.5-5m in length
