5. Export a separate map following step 5 in exercise 13b. (blue projection)
6. The two matching projections have a slight difference other than color, the Lambert (blue) and the Albers (green) have much of the same properties, but its where the cities are located on the diagrams. Its just that the cities locations are in the wrong place and the layers don't align correctly.

1. The type of projections that is used in exercise 13a were three versions of Albers equal area conic projections that depicts areas in middle latitudes for the most part.
2. A datum, a set of reference points on the Earth's of baseline measurements, it also contributes as a XY coordinate system. For all dataset/dataframes they all have the same datum as GCS_North _American_1983.
3. The largest US state in area is Alaska with a total of 663,268 sq mi
(1,717,854 km) in area.
4. Apparently in step 19 of exercise 13a, the state that appears to be the largest is again Alaska.

5. What is a Data Frame? A data frame contains different sets of data which is related to same subject that person works only more data frames are added. But not all data frame are the same, meaning they have different views of the data. For example, GIS Lab 2 ex. 4c has two data frames.
6. The main focus of the second data frame is the Area of Disapperance where Earhart and Noonan were given wrong coordinates and not enough flight info in Lae where the two paths disperse. The red path was the actual route to Howland Island, the other path is the wrong one which Nikumaroro Island.

Ch. 4 Qs- 4. The type of dataset I would use to determine the depth of the ocean from East Oceania, would be the raster dataset of seafloor elevation and its seafloor layer file.

1. Located under the map, the feature classes that is used in exercise 4a are like a group points, lines, polygons and sometimes cities/countries, for so the first 3 feature classes are also known as vector data.
2. While using the "Info" block on Australia, the info block managed to find identity results the country for instance, the population of Australia is a total of 17, 827,520.

7. In exercise 3c, while using the attribute table to find the cities, Earhart and Noonan encountered 28 cities during her flight journey.
8. While "Sorting" the length field of Earhart's flight, the shortest leg came out to be 793 kilometers (492 mi.) from Khartoum, Sudan to Massawa, Ethiopia coast to the Red Sea.
9. What was approximately the longest leg of her flight? -The longest leg of the flight was approixmately 3184 km. from Natal, Brazil across the Atlantic to Saint Louis, Dakar but the aviators were 175 km off course to Dakar , so with better flight plans it would of been 3009 km.

The South Pacific
4. Where was the end of Earhart's "planned" flight path? - The end of the "planned" flight path ends somewhere in the South Pacific in  Howland Island via to Hawaii and then to California.
5. "Measure" tool to calculate the distance between the end of the planned route and probable route. - Using the measuring tool from Howland Island (planned route/blue) to Nikumaroro Island (probable route/yellow) its about 768.552744 km. thats a rounding of about 770 km. (478 mi.)
6. What was the name of the island she should have completed her journey? - Knowingly, the last island is Howland Island via northeast to Hawaii.
