ADAM Wiki

Introduction

ADAM

In order to access the full functionality of ADAM, the Demo view needs to be deactivated, which can be done clicking the switch on the top-right of the screen.

Main Bar

Main Bar

The main bar includes three tabs and a search feature. The three tabs are:

  • Products tab
  • Geometries tab
  • Analysis tab

and will be explained throughout the following sections.

Products tab

The products tab is utilized to browse, search for and add available collections to your basket. Collections can be sorted based on sensor or application.

Adding and activating a collection

Adding a collection to your basket is simply achieved by clicking on the desired collection. The collection gets added to your basket and is activated automatically. A timebar appears on the bottom of the screen, data is displayed on the globe according to the most recent date.

The left animation shows how to browse the available collections on the platform and change the view-mode. The animation to the right shows how to add a collection and (de)activate it.

Data Discovery Adding a collection

Note! Some collections need your approval to the data's policy!

Data policy

Attention: Some collections will not get activated automatically after adding them to your basket, e.g. Landsat and Sentinel data.
Please refer to the Examples section to see how to handle those collections.

Timebar

The timebar enables you to change the data displayed on the globe according to your desired date, based on data availability. The currently activated day is highlighted using a bold font. Data availability is indicated by colored fields.
The following animation shows how to interact with the timebar, change the desired date and switch between activated collections.

Geometries tab

The geometries tab allows you to manage your location-related data, points and polygons.
The options to manage points and polygons are described as follows:

  • Remove point
  • Activate point
  • Show/hide point on globe
  • Zoom to point
  • Export point
  • Point info

Geometries tab

Adding a point

There are two ways of adding a point-location:

  • Manually adding a point:

A left mouseclick on any point on the globe will open the point settings pop-up. To save your manually added point, enter a name within the field 'Label' and click 'Save changes'. Optionally you can add tags or share your point-location with other users/collaborators. The point will be visible within the geometries tab.

  • Searching for and adding a point-location:

The easiest way to search for a point location is to utilize the search feature from the main bar (see top of this page).
A pop-up appears enabling you to save your query. After saving your point, it will show up in the geometries tab.

Adding a polygon/rectangle

As with points, polygons/rectangles can be added in two different ways:

  • Manually adding a polygon/rectangle:

To manually draw a rectangle/polygon, we need to access the 'Draw bar'. The draw bar, accessible via the pencil symbol can be found within all three tabs from the main bar. Once you have clicked on the rectangle/polygon symbol, you are ready to draw your geometry on the globe.

  • Searching for and adding a polygon:

The search feature from the main bar can also be used to locate polygons, e.g. the Peloponnese. Once saved, the polygon will appear amongst the list of polygons within the geometries tab.

Draw bar Rectangle

The following animation shows how to draw and save a rectangle and polygon.

Analysis tab

Within the analysis tab we can link collections with geometries, generate point-location time series and data layer subsets. In order to interact with data, you need to have activated a collection and at least added one point-location or polygon.

Generating a time-series from a point-location

Once a collection and a point have been loaded/activated, you will find the possibility to generate a time-series within the analysis tab. Click on the date to set your desired start and end date. Once defined, click the refresh button to generate the time-series. You can always change the date and refresh the plot following this procedure. The animation to the left shows how to generate a time-series, while the right one displays interacting with a plot.

Working with subsets

Data subsets are based on your added rectangles/polygons. When adding and activating a subset before loading a collection, the data will be served only for the subset and not globally, which enables faster visualization. A stack of subset layers can be generated to e.g. create an animation of layers. The animations below show how to work with the subsets-tab and query and add additional layers.
