605
XXXXXXXXXX
Module 12 Quiz
Suppose we have a Z-Order Curve with interspersed latitudes and longitudes such that a point with latitude XXXXXXXXXXand longitude XXXXXXXXXXis represented by rowID XXXXXXXXXXLet us also say that latitude 90S (south pole) is represented by XXXXXXXXXXdegrees, the equator is represented by XXXXXXXXXXdegrees, and 90N (the north pole) is represented by XXXXXXXXXXdegrees. Let us say that longitude 180W is represented by XXXXXXXXXXdegrees, 90W is represented by XXXXXXXXXXdegrees, 0 is represented by XXXXXXXXXXdegrees, 90E is represented by XXXXXXXXXXdegrees, and 179.999E is represented by XXXXXXXXXXdegrees. Suppose further that the Accumulo table represents the name of the tourist site at that latitude and longitude. A sample schema for the Accumulo table that represents the Eiffel Tower in France XXXXXXXXXX, XXXXXXXXXXand the La Moneda Palace in Chile XXXXXXXXXX, XXXXXXXXXXis:
    rowID
    columnFamily
    columnQual
    time
    value
     XXXXXXXXXX
    site
    Eiffel Towe
    
    
     XXXXXXXXXX
    Site
    La Moneda Palace
    
    
Write the pseudocode for the Map and Reduce methods that find all points within a latitude-longitude bounding box. Remember that the bounds of the longitude may cross the 0 degree meridian. Part of the grade will be dependent on the efficiency of your MapReduce pseudocode. Remember that the rowID has an interleaved format for efficiency reasons.
1) Map pseudocode
2) Reduce pseudocode

SOLUTION
The concept of data analytics, which covers the vast scope of the discipline and incorporates a variety of methodologies with a wide range of objectives, describes the process of analyzing raw data to identify trends.
A Point having latitude 33.333 & longitude 55.555 is expressed by row ID 3535.35355 in a Z-order curve with intermittent latitude and longitudes, according to this example. Let's suppose that longitudes 180W-, 90W-, 0-, and 90E- are each represented by 000.000 degrees, 90.000 degrees, 180.000 degrees, and 270.000 degrees, respectively. 359.999 degrees...
