Lesson Contribution: New learner clarifications
I'm a member of The Carpentries Core Team and I'm submitting this issue on behalf of another member of the community. In most cases, I won't be able to follow up or provide more details other than what I'm providing below.
This is a small thing, but in the Introduction to Raster Data section, if the learner did not have any experience with the raster data type, it might be clarifying to add a comment during the about section or add to the first key point, that the data represented/stored in each pixel/cell/grid has a single value/attribute of the phenomenon being described. The first image helps to show this, but it might be good to highlight it at this early point in the lesson. This might also help with understanding the composite values in multiband rasters.
