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.

1. Suggest an appropriate order for each data layer from top to bottom? An apprpoiate order for the layers that would make more sense would be putting Earharst's cities first (top), Flight route second, Countries third, and the Graticule last (bottom).
2. Name all US cities along Earhart's path: Oakland, Tucson, New Orleans, & Miami
3. Name other countries Earhart flies over: Karachi, Bangkok, Signapore, Darwin, & Natal

View Driving routes to Perquin, El Salvador in a larger map http://g.co/maps/38wyw Location Morazan, El Salvador C.A. for reasons of putting this map, it was unfinished from the original map. The map was missing a few routes and places where people/tourist can go, visit, and be aware of while going to the North Eastern outbacks of El Salvador. So then I modified it with a few details for people/tourist can convey and make use of this map to get to the town of Perquin to visit the Revolutionary Museum and Recreation Site.
