Learn how to apply topography in geography.
Exercise Steps and Questions
1. Configure the Equipment
Make sure the GPS is working properly. Please check the battery status on
the main menu (you get there by pressing the main menu button twice). If
the power indicator is significantly below 25%, please see the instructor to
get new batteries.
2. Collect Location and Travel-Time Data
In this step, you will need to collect locational data for each point and the
time it takes to walk between each location. You should plan on taking 1 hour
to collect this data . On the table on the next page, first write down the names
of seven places (the first place should be in front of the main entrance to the
building where class normally meets) you will collect location data for. Go
outside the main entrance and wait until you have excellent GPS satellite
reception (your accuracy should be less than 30 ft). Write down the coordi-
nates displayed on the GPS receiver, the departure time, and then start to
walk at a comfortable pace to your second location. When you get there
write down the arrival time and location information. When done writing this
information, write down the departure time and proceed to the next point.
Each point should be at least 200 m from any other point—further is even
Each connection between points should only be recorded once.
If you walk in the order of your locations, your arrival and departure times are
always related. However, if you change the order, you will need to make a
note of that on the worksheet.
3. Make a Map of the Locations
On a separate sheet of paper, prepare a drawing showing the geographic
locations of the data you observed above and the routes you traveled to
