Hi @GinaO_Neil and WIM users! I'm using the latest version of the archydro (3.0.50) WIM tools on groundtruth data that is multi-classed. When running the Preprocess Ground Truth Data, I'm checking that "features represent more than one target class" option and I'm unchecking the "class of areas outside of the ground truth features is known" option. The processed wetlands show up as expected with data classes of 0 and 1 and showing no data for the areas outside of my groundtruth data.
This is the groundtruth wetlands features (symbolized by class)
This is what they look like after preprocessing
The training raster looks good as well
I run into problems later in the workflow though - it seems like the 0 class of the raster gets merged with the no data section of the extents so my final predictions have 0 and 1 classes but the 0 class seems to reflect both the actual 0 class of data AND the no data areas. Once I've trained the model and built my composite raster here's what my prediction looks like
It predicts what I'd expect the 1 class to look like but the 0 class locations seem to merge with the no data areas from the groundtruth. Am I missing a setting somewhere or skipping a step?
Thanks!
