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 FAO56 model) that are communicated to ENORASIS system end users (farmers) via web or mobile. Identification information about each landzone is saved in 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 also send the valve activity for each landzone to the ENORASIS application server. Meteorological forecast data that derive from running meteorological forecasting models over satellite images come daily to the server and include a forecast for the next 72 hours. 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. istSOS is released under the GPL License, and should run on all major platforms (Windows, Linux, Mac OS X).

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

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.

The Sensor Observation Service standard
From http://www.opengeospatial.org/standards/sos
“The SOS 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).”
