The unit outline says that the report should be accompanied by before and/or after images. Is this referring to the 2 NDVI images used to perform image differencing?
For some people the before and after images will be the 2 NDVI images: for other people the before and after images will be 2 classifications. Include whatever is appropriate for your chosen change detection method. 8. I have already created a couple of sliced images through different variations of the conditional statement in the practical notes, which show 5 categories. I’m wondering if devising another statement for more or less categories is suitable for the project? (I was thinking of 3.) This could be an interesting final step to the project. When you use 3 categories some of the pixels that were previously shown as “changed” will now be shown as “unchanged”. It would be interesting to locate these pixels (either visually or using another spatial model) and then comment on why these pixels fall into a “maybe” category.
