In the graph, which line is most likely water, and which is most likely grass? How do you know? 

In a NIR false color composite, healthy vegetation will appear ________________________.

A ________________________ is used in remote sensing to compare, on a class by class basis, the match between the classified map and the ground truth data.

If the Kappa statistic is 68%, what does that mean?

Explain how the spectral and spatial resolutions differ between Landsat 7 and Landsat 8/9 using this figure. 

The user sets the number of classes in unsupervised classification.

Provide a remote sensing application that would require coarse spatial resolution but fine temporal resolution and an application that would require fine spatial resolution but coarse temporal resolution. 

Supervised classification uses training data to create groups of pixels.

Why does water always appear dark regardless of the band combination?

The vegetation index used in semi-arid regions where vegetation is sparse is
