using most in this course? The types of software products that are included in ArcGIS are ArcMap, ArcCatalog, and ArToolbook. We will be using the ArcCatalog the most in this course.
2. Would it be better to perform most of your data analysis and layer symbolization in
data or layout view? Why? It would be better to perform most of the data analysis and layer symbolization data view. In data view you are able to perform more changes to layer symbolization and data analysis.
3. What are two ways to obtain help for ArcGIS Desktop? One way to obtain help for ArcGIS desktop is by using the Identify tool.
4. How are attributes linked to geographic features?Attributes are descriptions of the geographic features such as the names of a country and a city on a geographic map.
5. What is the file extension of an ArcMap document? The file extension of an ArcMap document is .mxd.
6. What are two ways to zoom in/zoom out on a map? One way to zoom in and out is by using the tools toolbar and clicking on the zoom in tool. The other way to zoom in and out is by using the magnifyng window.
7. List three operations available in the ‘context menu’ of a layer. Hint: Right‐clicking
with your mouse in the TOC should help you with this question. Three operations available in the 'context menu' of a layer are paste layers, add data, and new group layer.
8. If the check box next to a layer in the table of contents is grayed‐out, what does this
mean? How would you resolve this issue? If the check box next to a layer in the table of contents is grayed-out this means that the layer's visibility is dependent on the maps visible scale. To resolve the issue you would zoom in to make the layer visible.
9. What are the differences between large and small scale maps? Provide an example of
each. The differences between large and small scale maps is the small scale maps are more detailed and larger scale maps are more general. An example of a small scale map would be the map of planet earth. A large scale map would be a map of the Island Tenerife, part of the Canary Islands.
10. Describe the differences between features and surfaces. Provide an example for each. Features represent geographic objects of some kind. And surfaces are what is the the surface of that feature.
11. A GIS is a useful problem‐solving tool. You can do all of the following tasks with it,
except one. Which one? B. Query data.
a. Create project criteria
b. Query data
c. Display data on a report
d. Store project data
Using the existing ArcMap document “Ex03c.mxd”, and the knowledge and skills you have
gained from the Chapter 3 exercises, answer the following questions:
12. What are the minimum and maximum elevations of the cities Earhart visited? Briefly
describe how you determined these values. The minimum and maximum elevations of the cities Earhart visited are 0, and 1045. I was able to determine these values by visiting the attributes table on the cities that Earhart visited and observing the table and finding the elevations for each city.
13. On the continent of Africa, what is the approximate distance (in miles) from Dakar to
Assab? What are two techniques (one tool and one process) you could use to figure
this out? The approximate distance from Dakar to Assab is 4,895 miles. One tool I used to figure out the distance is the measure tool in the tools toolbar. The process by which I figured to distance from the two cities is by going on bookmarks, adding length and measuring the length from the cities.
14. What are two possible methods you could use to figure out the names of the cities
shown on the map? The two possible methods you could use to figure out the names of the cities shown of the map is by right-clicking on the cities Earhart visited and clicking on label features. You are also able to click on the box next to Cities Earhart visited in order for it to have a check mark in the box so the cities a visible.
15. Zoom to the extent of North and South America so that all the cities Earhart visited are
labeled. Capture a screen shot (Alt + PrtScr) of this view and paste into your Word
document (Ctrl+v). Turn in this screen shot with your answers from this sheet.
