DamaGIS

DamaGIS is a GIS database which aims to collect and assess flood-related damage data at the local scale. What sets this database apart is the type of sources it uses. Indeed, all types of sources are considered such as on-site observations, online media or even social networks. Moreover, the database aims to be filled out in the future by a large number of contributors for the sake of data completeness and accuracy.

The reason for creating this database was the lack of precise damage data available to calibrate and validate flood risk assessment models. To this end, DamaGIS offers highly precise and easily accessible flood-related damage data. A simplified method to easily assess damage severity is also proposed to enable data comparison across time and location.

Since 2011, 729 damage entries caused by 23 flood events in the South of France have been reported within the database. The geodatabase contains two feature classes.

The first feature class is called “EVENT”. It is a shape field containing polygon geometries for geographic features. The EVENT feature class identifies flood events that have caused damage in the South of France since 2011.

The second and main feature class of the structure is the DAMAGE database, which catalogues flood-related damage. It is a  shape field containing point geometries for geographic features.

This version of the Database includes 3 different formats to enable using the Database with both QGIS and MAPINFO software.
