Combining Earth Observation Data
into a Crop Meteorological
Damage Alert System
(Calamities Information System)
Calamities Information System
An integrated system for the observation of
climate hazard phenomena in agriculture
through the Internet
A data combination model to estimate the crop
damage and the farmers compensation
outline
The goal is to monitor vegetation condition and to
evaluate the impact of climate hazards on the
environment and agriculture production.
The System combines Earth Observation data with low
resolution information in a ready-to-use form.
The system alerts the users, e.g. insurance companies, to
crop damage and aids them to compensate farmers
who have suffered.
Night frost in early spring, late spring/summer drought
and heat excess are the calamities which the System
addresses.
outline
The impact of climate hazards on vegetation condition
and subsequent damage is assessed using meteorological
and Earth Observation satellite data, as well as
complementary information such as agricultural statistics,
land use maps, tables of phenological stage by region and
ground data measurements.
Many types of data, e.g. stratification maps,
administrative boundaries and risk maps per type of
crop, are used and supplied depending on the calamity
concerned.
In the case of frost and drought, data from a
meteorological network are used to aid in the
interpretation of satellite imagery.
outline
The main scheme can be described as follows:
Under normal conditions, a monitoring system runs
and systematically generates synoptic trends.
The monitoring system activates the alert system
whenever risk factors are detected.
The alert system automatically produces
temperature maps of critical geographic areas,
maps of high risk areas,
maps of potential damages indication,
maps of minimum and maximum temperatures,
maps of drought index calculation, etc.
These products are generated by a processing chain and
are put at disposal of the end-users.
The end-users consult these products using an on-line
server.
