Tsunami Vulnerability Mapping Using Remote Sensing and GIS Techniques: A Case Study of Kollam District, Kerala, India

Inland wetlands mapping and vulnerability assessment using an integrated geographic information system and remote sensing techniques

The understanding of inland wetlands’ distribution and their level of vulnerability is important to enhance management and conservation efforts. The aim of the study was to map inland wetlands and assess their distribution pattern and vulnerability to natural and human disturbances such as climate change (temperature increase) and human activities by the year 2080. Inland wetland types i.e. for...

Analysis of seismic vulnerability using remote sensing and GIS techniques

This paper presents a framework to integrate several sources of spatial information to derive a map of seismic vulnerability for the city of Arica, Chile, which has been historically affected by this natural hazard. The proposed method is based on generating a geographical database with different variables that are related to human activity, considering factors of potential reduction and increa...

Assessment of Tsunami Damage to Mangrove in India Using Remote Sensing and Gis

Indian Ocean is the home to rare flora and fauna that act as the bio-shield to many coastal communities. Indian Ocean experienced the world’s most deadly natural disaster “Tsunami” on 26 December, 2004, which on one hand is unparallel in the history considering its magnitude and devastation and on the other hand, caused an unprecedented impact on the aqua and aqua terrestrial ecosystems. One of...

Assessing the impact of the 2004 tsunami on mangroves using remote sensing and GIS techniques

An assessment of urban environmental issues using remote sensing and GIS techniques an integrated approach: A case study: Delhi, India

India’s cities are growing rapidly, resulting in a wide variety of environmental stresses. In this paper an integrated approach using satellite data and GIS techniques in conjunction with socio-economic data is used to assess urban environmental issues in Delhi. Delhi’s current population of 13.8 million is growing rapidly, and is projected to reach 22.4 million by 2021. The issues addressed in...

GIS and REMOTE SENSING INTEGRETED FOR MALARIA RISK MAPPING, THE CASE OF KERSA DISTRICT, Ethiopia

Every year, malaria claims over a million lives around the globe. From which Ethiopia is a predominantly malaria prone country like most of sub Saharan African countries with about 75% of the landscape being favorable for the breeding of malaria vector and putting over 50 million people at risk. Attempts have been made to control the disease by eliminating the parasite. However, unknown spatial...
