We already
know the cartographic projections and the different kinds of maps; we have also
worked with coordinates and scales in maps of paper… Now we are going to work
with Google Earth. Most of you surely already know it, so today’s exercise
should be easy ;-)
But before
start, we need to install it! You can do it quickly from this link to the free
version:
Have you
finished? Now to start using it we need to know its different areas. Have a
look to the next image and localize each area in your computer:
Have you
find out what all the areas are for? Let’s work with them! All the activities
are mandatory, OK? Make sure you write your answers in a Word document (making
sure you save it with the .doc extension). You can include images from the
exercises, using the option “Save image” from the “File” menu and pasting them
into the Word document. Once you have finished all the work, send it by email to: blogeducativo08@gmail.com
Activity 1
Here you
can see a list of coordinates… You have to find out what city each one of them
belongs to. But take care with one thing! There is a condition when completing
this activity: you cannot use the Google Earth searcher; that would be
cheating! Remember that we are here to learn and not to compete, OK?
You must
use the option “Lat/Lon Grid” from the “View” menu to display the meridians and
the parallels and their numbers, and from there you must try to identify the
element. For example:
You must
identify almost five cities from the following list. Good luck!

Activity
2: The relief of Spain
Here we will try to identify several items from
the Spanish relief (ranges, plateaus…) and their main characteristics. In fact,
you should search for: Pyrenees, Teide, Peña de Francia, North
Plateau and Guadalquivir’s Valley.
To “see” them you must
follow the next steps:
- Activate the “Terrain” layer (“Layers” section) that allows you to observe the relief in 3D (spite of a flat photography).
- Change the terrain’s viewing angle to see the relief from another perspective, different to the normal top view.
Activity
3: Measure the Strait of Gibraltar
This exercise is the
easiest one of all. It will help you to learn how to measure (in straight line)
a distance with Google Earth. To do
that, you should allocate yourselves in the south limit of the Iberian
Peninsula and measure the distance to the African coast. That can be done using
the “Measure/Line” option in the “Tools” menu. For example:
