ENORASIS is an FP7-ENV Project which is developing a server based system that gathers data from satellite observations and remote sensing field equipment and exploits meteorological forecasting models to provide high spatial accuracy estimations for irrigation water needs, by taking into account information on specific crops and other factors affecting the irrigation process. These estimations are transformed in optimal irrigation rules (using also FAO56 model) that are communicated to ENORASIS system end users (farmers) via web or mobile. Information about each land zone is managed by the Land Management Subsystem. In the fields, sensors and water valves are deployed. The sensors collect raw data about various parameters affecting irrigation management (soil moisture, air temperature and humidity, solar radiation, wind speed, rain gage) and send their measurements to the ENORASIS server, where are managed through a istSOS 2.1 service. The water valves which also send their status to the SOS service are controlled by the ENORASIS application server. Sites specific meteorological models, which run over satellite images, daily provide the next 72 hours forecasts. istSOS (http://istgeo.ist.supsi.ch/software/istsos) is an OGC SOS server implementation the SOS service entirely written in Python for exchanging XML requests and responses. istSOS 2.1 allows for managing and dispatching observations from monitoring sensors according to the Sensor Observation Service standard. The talk will present the latest software enhancements (version 2.1) that include the availability of a RESTful Web API written in Python for automating administration procedures and wrapping SOS functionalities and a Web graphical user Interface written in HTML/Javascript/CSS that allows for easing daily operations like service administration or data manipulation. The presentation will go through the details of the new features. Finally future challenges and plans of the istSOS project will be illustrated and discussed. IstSOS is released under the GPL License, and run on all major platforms (Windows, Linux, Mac OS X) and is entered in the OSGeo incubation process.

ENORASIS
The project
ENORASIS is a FP7-ENV project (Grant Agreement 282.949). The project duration is three years (January 2012 – December 2014).
Objective
Develop an integrated decision support system for environmentally optimized and thus sustainable irrigation management for farmers and water management organizations based on advanced technologies and models.

The idea
•
New EU policies in the field of water and agricultural policies introduce the principle of “the user pays" in irrigation water management
–
WFD (Water Framework Directive)
–
CSS (Cross Compliance Scheme) of the EU CAP (Common Agricultural Policy).
•New tools and technologies allow the usages of granular information on the present and future state of the system:
–High resolution weather prediction models
–Low cost sensors
•New devices and spread of the Internet allow easy access to information for decision-making more conscious

WHEN, WHERE, HOW MUCH IRRIGATE
Users can access the ENORASIS system mainly by a web browser. The web platform is used by all the system actors (e.g. farmers, watering authorities, consultants and administrators) to perform their daily tasks. Most of the functionalities offered by the web application are also provided by the mobile application, developed for Android smartphones.

istSOS one enabler of the IOT
11
The Internet of Things (IoT) is the collection of billions of end devices intelligently connected and interoperating with servers and services.
Combine “Things” like Lego blocks to create applications, services, values….
How to chose the blocks? what are they? how do they fits together? We need well known language: standards for machine – machine interaction!
SOS is an OGC standard to:
•
register new sensor (THING) to the Web,
•
storing new observations
•
retrieving desired data

12. DACD / IST / ISTSOS in support of ENORASIS for optimizing irrigation
The Sensor Observation Service standard
12
From http://www.opengeospatial.org/standards/sos
“The Sensor Observation Service standard is applicable to use cases in which sensor data needs to be managed in an interoperable way. This standard defines a Web service interface which allows querying observations, sensor metadata, as well as representations of observed features. Further, this standard defines means to register new sensors and to remove existing ones. Also, it defines operations to insert new sensor observations. This standard defines this functionality in a binding independent way; two bindings are specified in this document: a KVP binding and a SOAP binding (in version 2.0).”
