As shown in the picture above, the Layer Page is divided into three main sections:
- the Layer Preview section, under the title
- the Tabs section, under the layer preview
- the Tools section, on the right side of the page
The Layer Preview shows the layer in a map with very basic functionalities:
- the Base Map Switcher that allows you to change the base map;
- the Zoom in/out tool to enlarge and decrease the view;
- the Zoom to max extent tool for the zoom to fit the layer size;
- the Query Objects tool to retrieve information about the map objects by clicking on the map;
- the Print tool to print the preview.
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.
The Attributes tab shows the data structure behind the layer. All the attributes are listed and for each of them some statistics (e.g. the range of values) are estimated (if possible).
The Share tab provides the links for the layer to share through social media or email.
You can Rate the layer through the Rating system.
In the Comments tab section you can post your comment. Click on Add Comment, insert your comment and click Submit Comment to post it.
Your comment will be added next to the last already existing comment. If you want to remove it click on the red Delete button.
