1. We envision …
• a system with dynamic understanding of the Earth’s
atmospheric, marine and terrestrial spheres for the benefit
of all European citizens
ENVIROFI Project Vision
Copyright © 2013 ENVIROFI 3

1. Bringing Biodiversity into the Future Internet
• Enables biodiversity surveys with advanced ontologies
• Analysis, quality assurance and dissemination of biodiversity
data
2. Personal Information System for Air Pollutants,
allergens and meteorological conditions
• Enhance human to environment interaction
• Atmospheric conditions and pollution in “the palm of your hand”
3. Collaborative Usage of Marine Data Assets
• Assess needs of key marine user communities
• Selection of representative marine use cases for further trial:
leisure and tourism, ocean energy devices, aquaculture, oil spill
alert
ENVIROFI Scenarios
Copyright © 2013 ENVIROFI 4

1. Enable users to provide objective, semi-
objective and subjective observations on
biodiversity
often in remote areas and under unfavorable
weather conditions
2. Integrate additional (possible contradictory)
observations from third-party databases
3. Assess the quality and meaning of the correlated
observation collections
Through combination of automated methods
and crowdsourcing
4. Assure the users are aware of the findings and
able to use them in own activities.

FI-Ware “Generic Enablers” already fulfill several
requirements common to many environmental application
scenarios:
1. “Single sign on" and authorization (Identity
Management GE)
2. Event handling (Complex Event Processing GE,
Publish/Subscribe Context Broker GE)
3. On demand scaling (cloud hosting GEs)
4. BLOB storage and retrieval (cloud storage GE)
5. Ad-hoc applications for specific users (composition &
Mashup Ges)

ENVIROFI-BIO APP
Walkthrough
App version 0.52, from 28.02.2013

Download and documentation on: http://catalogue.envirofi.eu
Note:
• Developed and tested on Android 4.1; not compatible with 4.0
• Expected to work (but not tested) on android v 2.3.3 and higher
App Download & Instalation

Login Screen
Login
1. Login using previously
registered account
2. Select from list of accounts
stored on phone
Demo Login
1. Choose one of the
“DemoUser” accounts
2. Press login
Note2: data entered by DemoUser
accounts will eventually be deleted

Popup Messages
The app uses two types of
popups
Help Messages
Most popup messages are
educational. These popups
can be safely turned off by
the user.
Warnings
In addition, the app will warn
users before performing
some “dangerous” operation
such as deleting the data or
starting a large data transfer.

Main Menu
List Observations
Browse through Objects of
Interest (trees), report new
objects and observations, define
new areas of interest.

Adding an Area of Interest (1)
First login & Areas of Interest
On fist login, the app will show
an empty map. User has to
define some areas of interest
before proceeding.
Note: if you choose an existing
account (e.g. demo 1), the app will
immediately start downloading the
users data in the background.
Pan and zoom to define
AoI position and size,
then press “Save” button

Ready to go!
Your data and AOIs
The app will now display the
known objects of interests
(previously reported trees) within
the new Area of Interest on a
map. New AoI appears in the
AoI list and can be used to
display the same area on a map
later.
Note: from now on, you can start
using the application offline. The
app will synchronize the list of OOIs
and observations within your AoI as
needed, whenever a network
connection is available

List View and Filters
List View
List view is synchronized with
the Map View and presents an
alternative view of the trees
within currently active map area.
Hint: press on a tree name to show
tree details
Filter View
Filter view can be used to pre-
select the trees corresponding to
filter criteria. The filter is
honoured by map and list view

Tree Details View
OOI versus observations
Most Objects of Interest in our
database are trees imported
from the tree cadastres of
Vienna and Florence.
Users can add new OOIs
(trees) as well as the
observations on existing OOIs.
Note: Our app currently displays
each report as a separate block
on tree details view, starting with
initial OOI. We plan to present a
fused view on all available
information in the future

Adding Objects of Interest
Why OOI?
Object of Interest is a concept
closely aligned with OGCs’
“Feature of Interest” and a
concept of “Thing” in Internet
of Things.
OOI is one of the main data
element of the Environmental
Georeferenced Observation
Service SE, and used to
represent trees in this app.
Tap here, to enter
the „add OOI“ mode.
Pan & zoom the map to
choose OOI location
Press the crosshair to report
a new OOI at this position

Adding Observations on OOIs
Why Observations?
Concept of observation originates
from the OGC Sensor Web
Enablement.
The “Observation” data element in
the Environmental Georeferenced
Observation Service SE and in
this app corresponds to
“observation collection” rather than
to a single O&M observation.
Note: mapping to standard O&M
schema is straightforward but
working with larger documents is
more efficient in our applications.
First open a „Tree
Details“ view, e.g. by
pressing on a tree icon
on a map.
Then Press
this button

Supported Observed Properties
LTER connection
ENVIROFI-Bio app has been
designed in cooperation with
the Austrian Long Term
Ecological Research Network
(LTER).
Starting with an empty sheet
The long list of observation
properties foreseen in the
LTER data model is grouped in
logical groups and each group
can be easily displayed or
hidden as needed.

Events in ENVIROFI applications
Working with Events
Propagation of Observations
and new OOIs is faciliated by
event-driven architecture of the
Observation Service SE. This
is already used to trigger
external processing services.
TODO
• Event-driven requests of
actions from users
• Pushing of events to FI-
Ware event processing
services

Working with NFC tags
Offline User interfaces
GUI handling of mobile apps
can be frustrating, especially in
bad weather conditions. Our
idea is to provide an alternative
method for user input using
external objects such as NFC
tags and 2D barcodes.
OOI identification with NFC
User can associate a tree with
an NFC tag. This tag can be
used as a shortcut to open a
tree details view later.

• Biodiversity: plants and animal sightings,
seasonal changes, invasive species, educational
• Forestry & agriculture: invasive species, spread
of pests & infections
• Administration: state of inventory, need for
actions (e.g. „this tree is about to fall“)
• Health: environment/health correlation, allergene
plants (see ENVIROFI PEIS pilot), light & noise
pollution
• Crisis Management: augmented reality for
training, improved situation awareness,
coordination of volunteers and field workers.
Possible Future Applications

• Produce and consume FI-Ware events
• „Best guess“ fused view on OOI based on all
available observations (instead of showing all
observations).
• Request QA observations from users as needed
• GUI changes to simplify quality-assurance by
users (“this an apple-tree, not pine-tree”)
• “Find/Locate a tree” function
• Deleting own OOIs and observations, deleting
Areas of Interest
• Publicly accessible Environmental Georeferenced
Observation (Proxy) Service
And more… We are looking for new projects to
continue development beyond ENVIROFI
TODO list

Coming soon …
