Hi everyone, This has only started occurring in the last week, and it is driving me insane. Has anyone else run into issues with rasters or feature classes randomly disappearing from geodatabases? It isn't just happening with one gdb, it is consistently happening with all of them I am working with. I'll do some processing, save the outputs to a file gdb, do whatever needs doing. Shut my computer down for the night, reopen it the next day to continue working, and half the files in the gdb now come up as having broken sources in the project. I go to check the gdb itself, and the files themselves have disappeared, so it isn't just a broken link. It's happening with rasters, tables, and feature classes. The first couple of times I assumed it was a corrupt gdb and recreated everything from scratch, but it keeps happening, even with newly created geodatabases. Anyone seen this happen before and have any ideas?  Thanks in advance! ... View more

Hi all To be clear, this error came out of nowhere. Everything was working perfectly yesterday, and today this started. No settings have been changed on my computer between yesterday and today. It occurs with every single tool I try to run, whether it be in Spatial Analyst, Data Management, Conversion Tools... Example below from when I try to run Extract by Mask. If I click yes to continue running the script, ArcMap crashes. Background Geoprocessing is disabled.  Running ArcMap Desktop 10.7 on Windows 10 (Chrome is and always has been my default browser, I do not use IE or Edge). I know this was an issue on older versions of Desktop, but I was under the impression it was resolved? And why would this randomly start occurring out of nowhere when it was working fine yesterday? Any ideas on how to fix? ... View more

I have been looking at the documentation for the Train Random Trees Classifier for Desktop 10.7 and the documentation for the Forest-based Classification and Regression tools in Pro and have a couple of questions that I hope someone may be able to answer. There is more documentation on the RF tool for Pro, however I am trying to do this on Desktop as that is what I have access to, so am just wondering how much of the information on the Pro tool applies to the Desktop version? For example, my main query relates to this. The RF tool on Pro states that By default, 10 percent of the training data is excluded from training for validation purposes. After the model is trained, it is used to predict the values for the test data, and those predicted values are compared to the observed values to provide a measure of prediction accuracy based on data that was not included in the training process. Additional diagnostics about the model, including forest characteristics, Out of Bag (OOB) Errors, and a Summary of Variable Importance are also included. Does this also apply for the RF classifier on Desktop 10.7? Is 10% of the training data also set aside and is this how the training accuracy value that shows up in the Geoprocessing results is calculated? And is there any way to get the OOB errors out of the Desktop tool? Or is that only available using Pro? Appreciate any help! ... View more
