7. Measuring Elevation Changes Graphing the GPS Data—Slide 7
If your teacher asks you to, you’ll make a graph similar to the leveling data graph.
For each station, plot the height for 2004 then the years when the graph is at maximum(s) or minimums. The data from GPS station OFW2 has been graphed for three dates.
Your teacher might have you graph every year.
The data is ‘messy’ so use an average height for the date.
Use a different color or symbol for each year’s data – but also make sure to use the same symbol and color for the same year on the different GPS stations.
Draw your colors and symbols in the key.
