Question

State one advantage of storing geographic data in the raster format rather than the vector format, and one advantage of vector over raster. Save Question 16 (2 points) Portland's latitude is given by N 45 degrees, 31 minutes, and 24 seconds. Convert this coordinate from degrees/minutes/seconds into decimal degrees. Make sure to show your steps (you can paste from your Calculator app and add explanations). Save Question 17 (4 points) I have come into the possession of the treasure map above which is said to have been in the possession of Captain William Kidd, a 17th century Scottish sailor who was tried and executed for piracy. There are two very faint handwritten notes on the map: 41 degrees, 5 minutes and 72 degrees, 7 minutes. No other notes can be discerned. Briefly describe two aspects of these coordinates that will make it difficult to find the location of the treasure

Explanation / Answer

15. The main advantage of raster over vector is that due to the relative nature of the data stored in the raster format, it is easier to perform data analaysis or techniques compared to the vector form. The advantage of vector over raster is that the data is represented in the original resolution and so the output of the data analysis will be far better than the raster format

16.Given: N45 degrees 31 minutes 24 seconds

So 450= "45" in the decimal format

31 minutes= 31/60= 0.516

24 seconds= 24/3600=0.00666

Therefore 45+0.516+0.0066= 45.5226

17.

the fact that 41 degrees 5 minutes and 72 degrees 7 minutes is very difficult to locate since the quadrants are not mentioned at the first place (that is N,S,W,E). Hence there are four probable locations and each of them will be miles and miles apart, hence the exploration of these points are difficult.
