KEY WORDS: Risks Management, Database, Data quality, High resolution images, Research support
ABSTRACT:
Following the 12th January 2010 earthquake in Haiti, the French Agence Nationale de la Recherche has funded a project named
KAL-Haiti which aims at gathering remote sensing imagery as well as in-situ and exogenous data into a knowledge base. This
database, seen as a shareable resource, can serve as a basis for helping the reconstruction of the country, but also as a reference for
scientific studies devoted to all phases of risk management. The project main outcome will be a geo-referenced database containing a
selection of remotely sensed imagery acquired before and after the disastrous event supplemented with all relevant ancillary data, and
enriched with in-situ measurements and exogenous data. The resulting reference database is freely available for research and for
reconstruction tasks. It is strongly expected that users will also become contributors by sharing their own data production, thus
participating to the growth of the initial kernel. The database will also be enriched with new satellite images, monitoring the
evolution of the Haitian situation over the next 10 years.
1. INTRODUCTION
The earthquake that struck Haiti in January 2010 is amongst the
most destructive disasters of recent years: more than 200 000
lives lost, tens of thousands injured, close to 2 million people
made homeless, the entire country must be rebuilt The
response of the international community has been
unprecedented. Over and above the emotion brought on by the
terrible scenes in the aftermath of the earthquake, our focus is
now turned to rebuilding the country. In addition, using the
abundance of data available, this case must be studied with the
aim of better understanding seismic hazard and vulnerability in
this zone and elsewhere.
During the immediate response to the disaster, tens of satellite
images, both optical and radar, covering various spatial
resolutions were acquired by satellite operators whether they be
national space agencies or private companies. To these were
added aerial photography and in situ measurements. After
photo-interpretation, these images were used by the civil
protection agencies that sent teams to the scene.
Too often limited to this « response » phase, this earth
Observation and in situ data should be available for use by
relevant agencies involved throughout the disaster management
cycle : from recovery, to mitigation, to preparedness. A
prerequisite for making all this data available (in situ
measurements, images, maps, models, reports, statistical data)
to users (decision makers for the reconstruction effort,
scientists) must be that it is accessible in an easily exploitable
form (geo-referenced, corrected, validated and dated).
This paper presents the KAL-Haiti project which has been setup
in order to propose a new resource freely accessible by
researchers, developers and final users, for developing and
evaluating new solutions in the disaster management cycle.

2. MOTIVATIONS
Researchers and solution developers must exhibit extensive
know-how and a good dose of creativity in order to devise
innovative solutions to the complex problems they try to solve.
However, this is not sufficient. Firstly it is better when the
problems correspond to real issues and are defined by the
potential users, either directly or indirectly, and secondly well
documented and qualified datasets must be available and
accessible in order to design and validate the proposed
solutions.
Taking into account the humanitarian importance of the Haiti
earthquake catastrophe and the strong demand for helping
reconstruction, as well as the huge amount of available data
related to this situation and the complexity of this crisis
management, the KAL-Haiti project's principal aim is thus to
produce and promote the use of a database of earth observation
(remote sensing and in situ) and associated data concerning the
Haiti earthquake, defined and used jointly by end users and
scientists.
The reference infrastructure that is setup by the project,
containing freely exploitable data, provides an invaluable
resource for research into developing methods of analysis for
users involved in disaster management from pre-event
preparedness to the return to normal after the event, but also
during the reconstruction phase currently underway in Haiti.
This project is aligned with current activities in the partner
organisations. These include the CNES ISIS and KALIDEOS
programmes which provides improved access for the science
and applications community to SPOT imagery, and CNES'
participation and role as project manager for the Haiti disaster
for the International Charter on Space and Major Disasters.
