Teacher Guide This ArcGIS activity contains one Layer with six (6) themes: Cities, Countries, Lakes, Rivers, Latitude/Longitude Lines, and World Base (used for oceans). Students follow the activity guide to create the project file on their own and use the proper tools to answer the included questions. The activity assumes a base directory of ‘C:\ESRI\Projects’ for all activity related actions. Text within this document should be changed based on local settings. Teacher Guide 2 Lesson Preparation The shapeflie layers in this project are provided in a standard installation of ArcView. They are contained in the ‘C:\ESRI\ESRIDATA\World’ directory: C:\ESRI\ESRIDATA CITIES.shp country.shp Materials Sources ESRI Installation Datasets Developed by Steve O’Connell geographilia@hotmail.com Exploring the World with GIS Exploring the World with GIS LAKES.shp latlong.shp rivers.shp WORLD30.shp


Maps come in many different forms. Most people have seen a standard road map and possibly used one to plan a trip. Paper maps such as a road map have been available for many thousands of years and have been important tools for people traveling around the globe. In our modern world, much of the information on a map can be transferred to computer-based maps. You may have used computer-based maps on online sites such as Yahoo! Maps or Mapquest to find directions. These online road maps are part of a larger collection of mapping programs known as Geographic Information Systems or GIS. In this activity, you will learn the basic tools of the GIS program ArcView. ArcView is widely used by professionals, scientists, and students in a variety of subjects. Like any computer program, it will take some time to learn how to use all of the features of ArcView. This exercise will give you a basic understanding of how to view data, find information, change the map display, and create a printable map. Some features will be easy to learn, others will require practice. As you become familiar with ArcView through this activity and others over the rest of the year, you will become more comfortable with using GIS. Exploring the World with GIS


2 Step 1 Getting Started To begin, open ArcView GIS 9.1 by selecting the icon on your desktop. At the ArcMap menu, select ‘A new empty map’ and click ‘OK’. Click the ‘Add Data’ button. Click the ‘Up One Level’ button until the ‘Look in:’ box says ‘Catalog’. Double-click on the ‘C:\’. You will need to select the following datasets: Double-click on ‘ESRI’. Double-click on ‘ESRIDATA’. Double-click on ‘WORLD’. Your Data selection should look like the list here CITIES.shp LAKES.shp latlong.shp RIVERS.shp WORLD30.shp (Hold down the ‘Ctrl’ key to select more than one item.) Once you have selected the datasets, click ‘Add’. country.shp Exploring the World with GIS


3 Step 2 Viewing Data in ArcView Your project will open with a world map in the main screen and the list of layers on the left. It should look similar to the map below. If you do not see this tool bar you will need to turn it on. To do this, click on “View” on the main menu toolbar, then scroll down to “Toolbars”. Under “Toolbars”, click on “Tools”. Your “Tools” toolbar will appear. Using the check boxes next to the layers, turn off every layer EXCEPT ‘country’ and ‘WORLD30’. To make the map easier to view, you should turn off a few of the layers. Exploring the World with GIS


4 Step 3 Changing the Map Styles It is possible to change the look of the map by changing the colors and style of the map layers in the view. Use the following steps to change the colors of the two visible layers. Double-click on the ‘WORLD30’ layer in the list on the left. Click on the ‘Symbology’ tab in the Layer Properties menu that appears. Click on the Symbol box to open the Symbol Selector menu (seen to the right). Select the ‘Blue’ option from the list (it should be the first choice in the right column). Click ‘OK’on the Symbol Selector menu. Click ‘OK’on the Layer Properties menu. Double-click on the ‘country’ layer and repeat the steps from above. Make sure that you choose a color from the list in the Selector menu that is easy for you to see. Your map should have changed slightly – the lines will have disappeared from the ocean areas. Exploring the World with GIS


5 Step 4 Saving Your Map It is always important to save a project when working in ArcView. To save your current work, follow the directions below. From the Main Menu toolbar, click ‘Save’. In the ‘Save in:’ box, select ‘Local Disk (C:)’. Double-click on the ‘Documents and Settings’ folder. Double-click on the ‘All Users’ folder. In the ‘File name:’ box, type “GIS map XXX” (replace XXX with your initials. Click ‘Save’. Step 5 Using the Zoom Tools A GIS map is useful because you can move around it at your own pace. Using the existing set of tools can be helpful. Select the ‘Zoom In’. Draw a box around Africa by holding down the left-mouse button. Use the ‘Back to Previous Extent’ tool to return to the view of Africa. Repeat the same function to zoom into the country of Madagascar (the island off the south east coast of Africa). Exploring the World with GIS


6 Step 5 (Continued) Experiment with the zoom tools seen here: Provide the name of the tool and what it does: Tool Name Function Select the ‘Find’ tool. There is one last zoom-related function to examine. A dialog box should appear (see example to the right). In the Find field, type ‘Colombia’. Select ‘country’ from the ‘In’ list. Click ‘OK’. Results will appear at the bottom of the dialog. Right-click the result. Select the ‘Zoom to feature(s)’. Exploring the World with GIS Fixed Zoom In Fixed Zoom Out Zoom to Full Extent Pan Zooms a set amount in Zooms a set amount out Shows the entire map Moves the map in the screen


7 Step 6 Identifying Map Features Select the ‘Identify’ tool. The map in front of you may not be very useful if you do not know what you are looking at. ArcView provides several ways to identify features on the map. Population Right-click on the ‘country’ layer. Select ‘Label Features’. Exploring the World with GIS An Identify Results window will appear above the map. Click on Colombia (the country in the center of the map). The Identify Results window will display a number of pieces of information about the country of Colombia. Complete the table below using the data from ArcView: Feature Field Name Value Population per Square Kilometer Population per Square Mile Currency Type Other features on the map can be revealed through other ArcView tools. The country names should now be visible on the map. List the names of the five (5) countries that border Colombia: 4. 2. 5. 3. POP_CNTRY SQKM_CNTRY SQMI_CNTRY CURR_TYPE Peso 440911.5 1141962 34414590 Panama Venezuela Brazil Peru Ecuador


8 Step 7 Moving Map Layers Use the proper zoom tool to zoom out to the entire world. Move the layer up so it is above the ‘country’ layer. Exploring the World with GIS You now know how to move around in ArcView and how to identify features of the data layers. It is possible (and sometimes necessary to rearrange the layers within the map view. Remove the country labels to make the map easier to read. (Right-click the layer and un-select the ‘Label Features’ option). Turn on the ‘RIVERS’ layer by selecting it’s check box. (You may want to change the color). Turn on the ‘LAKES’ layer by selecting it’s check box. In the layer list, click and hold on the ‘LAKES’ layer. No Lakes appeared on the map when you selected the layer, did they? This is because the ‘LAKES’ layer is underneath the ‘country’ layer in your map. You can rearrange the map layers to help view the ‘LAKES’ layer. The ‘LAKES’ layer is now visible. You can change the color if you need to.


9 Step 8 Using Your New Skills Exploring the World with GIS These are just a few of the tools that are present in ArcView. You will learn to use many more in the coming weeks, but to finish this activity you should try to use the data in this project to answer the questions below. If you have questions or get stuck, ask your teacher for help. Name the three cities displayed in the country of Iraq. 1. 2. 3. What are the names of the two rivers that flow through Iraq. 1. 2. In what country do these rivers start? - If you have time, try to use some more advanced features identify features of the world’s largest cities. (Hint: Use the right-click on the appropriate layer to open the layer attribute table. You will also need the right-click within the table.) World’s Largest City: Population of the Largest City: Number of Cities with More than 10 Million People: Name and World Rank of the Largest US City: What is the largest city in Morocco? - Is this city the capital? What is the capital? - - What country is sovereign over (owns) Greenland? - Turkey Casablanca No Rabat Denmark Tokyo 23,620,000 11 New York; #2 Mosul Baghdad Al Basra Tigris Euphrates
