This map section gives access to Satellite and GIS Data by using a distributed network of Web Map Servers (OpenGIS specification).
Several of the servers distributing the satellite and GIS data are running on ESA's computers at ESRIN, Italy.

About the map viewer |
|
Once you have selected the geographical region and
time period you are interested in, you can choose what information
you would like to have displayed on the map. The Layers Control
displays the data that you have selected and allows you to add and
remove layers, as well as modify the order with which these layers
are displayed.
 |
Click on "select layers" at the
bottom right of the EoPortal Web Map Server. The Layers
Control appears, which you can keep open to view the
effect. |
 |
To define a layer, you must choose
a Category, which may contain different Themes. For each
theme, one or more layers will be displayed for you to choose
from. By clicking on a layer, more information about that
layer is displayed below. Click on the arrow to select
highlighted layers. The layer appears in the list of Selected
Layers, to the right. |
 |
A highlighted layer may be removed
from the Selected Layers list by clicking on the X. Shift the
layers up and down to avoid some layers obscuring others.
Click on OK to view the map. |
