When I’m on social media I often see comments about the need for a revolution.
Do you agree? How would you go about it if so?
I’m imagining nationwide strikes and the boycotting of major corporations.
Hello! I am very much a beginner with ArcGIS but am using it for a masters project.
I am trying to do a classification of a saltmarsh habitat, focusing on an invasive species. I have been trying different ways to train the data for 12 hours a day the last 3 days, and I am going insane, please help if you can!
- The images are 2.5cm and the area is relatively small (500m by 50m)
- I have done 'segmentation' on the images and done training samples using the circle polygon (maybe this is where I'm going wrong??).
- I have used 7 different classes (my target invasive species, 3 levels of green vegetation, creek bank, creek dark and creek light) with 60-100 training samples.
- Using Classification Wizard to do Random Forest classification.
- Results suck.
Please let me know any advice you might have, whether it's changing methodology, anything. I am trying to be very preceise with my training samples so don't think it's that.
