To complete this project you will need to understand how to use the interactive map of Virginia shown below.
Click anyplace on the map to move the cursor to that point.
Notice the readout at the upper right gives the location of the cursor measured in pixels from the lower left corner of the map.
You can fine tune the location of the cursor by clicking on the four arrows at the left, right, top, and bottom of the map. Each click moves the cursor one pixel in the direction indicated by the arrow.
Questions:
Find the coordinates of Roanoke and of Richmond.
For our purposes we will assume the coordinates of the southwest corner of Virginia are (24,98). Locate this point on the map.
Click the blue "Mark point" button to create a point on the map at these coordinates.
Mark any 5 additional points on the northern state boundary. Record the coordinates of these points.
Assume the coordinates of the southeast corner are (474, 98). Mark this point on the map.
Click the red "List points" button. (You may need to enlarge the window that opens up.) Compare the values that you recorded to the ones in this list. Can you see how they are the same?
Click the black "Clear points" button, and then repeat steps 2-6 until you are comfortable with this process.
