Short Answer.  Answer 5 of the 6 short answer questions on this and the following  pages.

 

1.  Answer only one of the following two questions:

 a.  What are the similarities and differences in the following three file formats:

2.  Differentiate spatial, radiometric, spectral, and temporal resolution with satellite data.  How are these related to the signal to noise ratio and attempts to build spy satellites?

 3.  Explain (do more than just list) 5 functions of a scientific society:

1.        

2.        

3.        

4.        

5.        

 5.  Differentiate the Mercalli and Richter scales.

 6.  What are the similarities and differences between filtering in one dimension (as we did with the YP data) and in two dimensions (as we did with the satellite imagery)?  What is the purpose behind the procedure?

 

Longer Answer.  Answer this question.

 This data shows the distribution of record rainfalls by decade in the bin column.  The Frequency column show the count of records, the uniform column shows the expected value if each decade had the same number, and the pyramid column shows the expected value if the distribution had a peak in the 1980's . 

 The two chitest values show the results Excel calculated, comparing the two hypothesized distributions with the observed frequencies.

 What do the results of the two tests show, and what can we conclude from them?
