Until recently, no systematic, dynamic, and cost-effective data collection strategy has been available for use in the study of post-disaster neighborhoods. In order to address this concern, we employed a geospatial approach, ÛÏspatial video,Û which links video with coordinates acquired by a Global Positioning System receiver. This advance enables new study of the dynamic spatial and temporal scales of post-wildfire recovery.
A discussion of outcomes from the 2013 ÛÏGEOSS Future Products WorkshopÛ held at the NOAA Science Center in Silver Spring, Maryland. The focus was on connecting Sensor Webs to Model Webs to generate a wide portfolio of on-demand and near real-time products accessible through citizen-oriented applications for diverse types of GEOSS users.
Attempts have been made to model wildfire susceptibility by means of different methods. This paper focuses on susceptibility as a property of a given territory, under the assumption that even though a land parcel is not static in nature, it is sufficiently stable to support a structural approach.
By N. Kodandapani Asian Nature Conservation Foundation, Center for Ecological Sciences, Bangalore, India ABSTRACT There is uncertainty regarding the extent to which drought, fuel availability, and ignition sources contribute to the global fire regime. In 2004, sharply increased fire activity followed a severe drought, highlighting the importance of droughtÛÒfire linkages in the Western Ghats hotspot of biodiversity. The spatial extent … Read More
“Visuals touch both the mind and the heart in ways that writing alone can’t. That revelation, plus my decades-long fascination with the science of our planet, led me to create ImaGeo.Û Tom Yulsman, ImaGeo.
Climate change is contributing to larger wildfires and a longer fire season, making the need for near-real time and ultra-precise maps of fires more critical than ever. A team at the National Interagency Fire Center (NIFC), in Boise, Idaho, (USA), is responding to that demand with new and better mapping technologies.
Noise from various sources, such as clouds, is present in satellite observations. This noise, as well as low contrast in satellite images, prevents automatic tools from processing each image independently. We developed an approach which processes all images simultaneously and enforces the constraint that the burned areas can only grow in time. This allows the exploitation of temporal information not available for a single image.
Data products and tools from the LANDFIRE Program help decision-makers clarify problems and identify possible solutions when managing fires and natural resources. The Program – a joint effort between the U.S .Department of the Interior Office of Wildland Fire, U.S. Department of Agriculture Forest Service Fire & Aviation Management, and The Nature Conservancy – provides the only complete geospatial dataset describing vegetation and wildland fuel information for the entire U.S.
The National Observatory of Athens (NOA) in Greece offers operational Earth Observation services for disaster management of forest wildfire. Dedicated systems offer stakeholders online access to robust, accurate and fully operational Web-based tools to assist their Emergency Response and Emergency Support actions.
What is causing dangerously flammable seasons in the U.S. and abroad, and what can we do to address them? Remote-sensing technologies are increasingly being used to track live fires and promote prevention by identifying potential ÛÏhot spotsÛ and characterizing pre-fire conditions and risks.
