Human-guided Flood Mapping on Satellite Images
Flooding is responsible for substantial loss of life and economy. Flood mapping, the process of distinguishing flooded areas from non-flooded areas during and after a disaster, can be very useful in guiding first response resources in a disaster situation, and in assessing flood risk in future disaster scenarios. This paper involves the use of image segmentation methods and human guidance to pr...
متن کاملTowards Operational Flood Mapping with Satellite Sar
Space-borne SAR sensors are of special interest for mapping flood extent due to the possibility to acquire images in all weather conditions. In this article we review the SAR part of an operational flood mapping service. An operational service requires fully automatic methods that are able to process any available SAR data in near-real time. Mapping flood with SAR requires different approaches ...
متن کاملPotential and Limitations of Highresolution Satellite Imagery
The issue of commercial highresolution satellite images has found much interest lately within the remote sensing and geoinformation communities. Performance predictions and business expectations have come close to revolutionary changes in the geoinformation industry. Several missions have been planned but only one system made it successfully into orbit. Since the costs of images are high, only ...
متن کاملFlood Forecasting and Inundation Mapping Using HiResFlood-UCI and Near-Real-Time Satellite Precipitation Data: The 2008 Iowa Flood
Floods are among the most devastating natural hazards in society. Flood forecasting is crucially important in order to provide warnings in time to protect people and properties from such disasters. This research applied the high-resolution coupled hydrologic–hydraulic model from the University of California, Irvine, named HiResFlood-UCI, to simulate the historical 2008 Iowa flood. HiResFlood-UC...
متن کاملA Neural Network Approach to Flood Mapping Using Satellite Imagery
This paper presents a new approach to flood mapping using satellite synthetic-aperture radar (SAR) images that is based on intelligent techniques. In particular, we apply artificial neural networks, self-organizing Kohonen’s maps (SOMs), for SAR image segmentation and classification. Our approach was used to process data from different satellite SAR instruments (ERS-2/SAR, ENVISAT/ASAR, RADARSA...
