Automated, web-based environment for daily fire risk assessment in New Caledonia


In New Caledonia, the increasing number, frequency, and extent of fires represent both a danger to human life and a threat to ecosystems conservation in an area considered to be a sanctuary of biodiversity. A four-year study was carried out in the framework of the INC research project to better understand why fires start and to improve fire prevention. Based on satellite observations, a model was built to calculate the risk of fire ignition, together with a Bayesian network to link data on social, environmental, and climatological risk factors. The model and environmental, geological, and topographical data can be used to assess the impacts of fire on biodiversity and erosion. The purpose of this paper is to present a tool designed to produce on-the-fly maps showing fire risk obtained. This web-based tool implements the model built during the research project and provides fire risk maps every day thanks to an automated recovery of climate data. The user only has to select the date of interest in order that the tool manages all the process of maps creation and display. Open Geospatial Consortium (OGC) is an international organization in which governments, trade research, and non-profit structures collaborate to implement open standards related to services and geospatial content, as well as GIS data processing and sharing. The presented tool has been made with some standards specified by OGC (Geography Markup Language, Web Map Service), allowing it to be interoperable with other systems that implements OGC standards. An online tool that exploits live results of the model and automated filling of a database enables identification of high fire risk sites. It then facilitates the task of land and environmental management by combining geographic data on location of water resources and roads that can be used to reach the potentially dangerous sites of fires.
