Ellip is a global collaborative platform prepared for the data-driven economy. It connects consumers and producers of resources, interacting on the platform to produce software items, service endpoints, data assets. Ellip is moreover a work environment leveraging earth observation standards and an “Open Cloud” strategy.

4. About us
● Terradue is a SME based in Rome, founded in
2006 with support of ESA BIC
● From day one providing support to
application builders in Earth sciences, to
use satellite EO data as information source
● Cloud Platform-as-a-Service & APIs (ellip) for
the transfer in production of scalable
software applications
● Business model: Platform-centered (PaaS,
SaaS), collaborative workplaces for value
adders to interact & co-create
https://www.terradue.com

5. Ellip users are EO applications builders

6. Purpose
● A collaborative platform:
○ Consumers and producers of resources
interacting on the platform
○ Resources: software items, service
endpoints, data assets
● A work environment leveraging earth
observation standards
● An “Open Cloud” strategy

7. Ellip: an Open Cloud strategy
▪ The Ellip subscribers remain the owners of
their created assets, and decide how to
share these on the platform, for other users
to find and reuse these assets.
▪ They are also empowered to decide on the
target production environment of their
packaged applications (no lock in with
Cloud provider)
Producers
Consumers

32. Use Cases
● Use Case 1: Adapt my application for the
automated use of the new Copernicus
Dataspaces (CDS) data repository
● Use Case 2: Deploy an Application Package
on a ‘standardized’ Platform host, via the
OGC Process API
● Use Case 3: Configure a user dashboard
(e.g. a custom geobrowser)

33. Use Case 1
Ellip Studio
Adapt my application for the
automated use of the new
Copernicus Dataspaces (CDS)
data repository

34. Ellip Studio access Code server
From your Ellip Studio environment, edit the Application Package
“app-package.cwl” file as follows:
● Add the "entryname: config.yml" section that
contains “Plugins" and “Credentials” sub-sections,
with the information related to “CDS" config info
● Assign the config.yml file that will be generated in
the Docker container, to the variable “config_file”
● Finally, in the Stars command, you need to add the
flag -si to select the provider “CDS”, and the config
file:
Stars copy --harvest -v -rel -r 4 -si
CDS -conf=${config_file} -o ./
${reference}
https://www.commonwl.org

35. Use Case 2
Ellip Launchpads
Deploy an Application Package on
a compliant Platform host via the
OGC Process API

36. Ellip Launchpads load your Deploy Notebook
Objective: Deploy an App-Package from a private
repo into ADES
● Authenticate to access the Gitlab repository
connected to your Ellip Studio
● Define Service Name and Version
● Read the content of the App Package from
private repo
● Replace username and password for CDS
● Upload the App-Package on the deployment
space
● Deploy the App-Package CWL on the ADES
server
● Check if the service has been deployed
successfully
● Discover information on the deployed service

37. Ellip Infohubs
Configure a user dashboard
Use Case 3

38. Ellip Infohubs my communities
The initial page provides with the browse and search functions over the
communities managed by the user:

39. Ellip Infohubs my communities
The initial page provides with the browse and search functions over the
communities managed by the user:

40. Ellip Infohubs new community
Create a new community via the button “+ Create new”.
This will open an input form simply asking for basic properties: Identifier, Title, Description,
Icon url. This allows to create a new community to be saved as “private” to the user.
Once saved, the user will be able to edit more advanced properties.

41. Ellip Infohubs geobrowser editor
The default view (tab “My personal apps”) lists the previously created
applications, allows to search for such existing applications, and
allows to create a new one (cf. button “+Create new”).

42. Ellip Infohubs geobrowser editor
A second view (tab “My shared apps”) lists the previously created
applications that have been shared in the user shared indexes.

43. Ellip Infohubs editor: properties
Finally, when creating a new Application, the user is accessing a group
of input forms, allowing the configuration of the resources to be
connected to the new information hub, and the definition of some
visualisation settings for the application users.

44. Ellip Infohubs editor: basemaps
Select the styling of the map layout that will support spatial interactions
with content in the application (navigation, zoom, …).

45. Ellip Infohubs editor: map features
Currently, only OGC WMS layers can be added

46. Ellip Infohubs editor: data collections
Data collections can be grouped using a “first level” context. Each
context with several collections will appear as a dropdown menu
button on the geobrowser application.

47. Ellip Infohubs editor: data features
To enable additional data features to be presented to the users in your application:
● Data search: to allow to search over defined data collections and list search results within a Search Result tab
● Feature Basket: to allow user to temporarily save datasets returned by search results into a dedicated Feature basket
● Data Packages: to allow the user to load/save data packages
● Store Upload: to allow user to upload local data on his private storage
● Timebar: to allow user to search using the timebar
● Time series: to allow user to visualize results as time series on a dedicated view
● Geobrowser plugins: to browse a list of available geobrowser Plugins and select

48. Ellip Infohubs editor: wps services
Allow user to process new jobs from a list of available processing
services, visualize the results on the map and share it with other
users, as well as access shared jobs from other users.

49. Ellip Infohubs editor: save
To finalise the application, and save it in a personal space (my
personal apps) or in a shared space (my shared apps).
