| 1 | First extensive and cost-effective quality check of Crisis Maps: presentation of assessment parameters and results显示文摘The digital representation of disaster situations into maps,mainly based on remotely sensed observations,is becoming a widely used instrument for emergency management.Thousands of maps are being produced all over the world and big attention is paid by international institutions,such as the World Bank,the United Nations and the European Commission to these tools.The quality of crisis maps is a crucial element to ensure effectiveness in the disaster response chain,but it is often neglected with respect to the need for a rapid delivery.In this paper a sample of crisis maps produced between 2005 and 2010 by world leader providers has been evaluated through around 40 parameters assessed by visual analysis and extracted from the validation protocol designed at the Joint Research Centre(JRC)of the European Commission.The maps turned out to be in most cases clearly readable,but some gaps and inconsistencies have been singled out,due to the lack of international standard references.The results are analysed in detail and some remarks are presented. | D.Carrion C.Corbane M.Broglia M.Pesaresi | 2013 | International Journal of Digital Earth2013，6，S02： | 0 |
| 2 | Development and implementation of a validation protocol for crisis maps: reliability and consistency assessment of burnt area maps显示文摘Validation is an emerging topic in the field of geospatial information for emergency response.In the framework of the Global Monitoring for Environment and Security initiative,the Services and Applications for Emergency Response project seeks to implement and validate the pre-operational version of Emergency Response Core Services.In that context,a dedicated effort has been made in the development and implementation of a comprehensive,productoriented validation protocol tailored to crisis maps and data sets.This paper presents the approach for validation of crisis maps and its application in the context of rapid mapping of forest fires in Corsica during the summer of 2009.It also discusses the main challenges and the critical aspects of validation of geospatial information in emergency response services. | C.Corbane D.Carrion M.Broglia | 2011 | International Journal of Digital Earth2011，4，S01： | 0 |
| 3 | The Generalised Settlement Area:mapping the Earth surface in the vicinity of built-up areas显示文摘Geo-information on settlements from Earth Observation offers a base for objective and scalable monitoring of the evolution of cities and settlements,including their location,extent and other attributes.In this work,we deploy the best available global knowledge on the presence of human settlements and built-up structures derived from Earth Observation to advance the understanding of the human presence on Earth.We start from a concept of Generalised Settlement Area to identify the Earth surface within which any built-up structure is present.We further characterise the resulted map by using an agreement map among the state of the art of remote sensing products mapping built-up areas or other strictly related semantic abstractions as urban areas or artificial surfaces.The agreement map is formed by a grid of 1 km2,where each cell is classified according to the number of EO-derived products reporting any positive occurrence of the abstractions related to the presence of built-up structures.The paper describes the characteristics of the Generalised Settlement Area,the differences in the agreement map across geographic regions of the world,and outlines the implications for potential users of the EO-derived products used in this study. | A.J.Florczyk M.Melchiorri J.Zeidler C.Corbane M.Schiavina S.Freire F.Sabo P.Politis T.Esch M.Pesaresi | 2020 | International Journal of Digital Earth2020，13，1： | 0 |
