Layer Information

In this section you will learn more about layers. In the Layers section we explain how to find layers, now we want to go more in depth showing you how to explore detailed information about that.

Layer Information

As shown in the picture above, the Layer Page is divided into three main sections:

  1. the Layer Preview section, under the title

  2. the Tabs section, under the layer preview

  3. the Tools section, on the right side of the page

The Layer Preview shows the layer in a map with very basic functionalities:

Tabs Sections

The Layer Page shows you some tabs sections containing different information about the layer:

  • The tab Info is active by default. This tab section shows some layer metadata such as its title, the abstract, date of publication etc. The metadata also indicates the layer owner, what are the topic categories the layer belongs to and which regions are affected.
