ASSESSING THE IMPACTS OF FLOODING CAUSED BY EXTREME RAINFALL EVENTS THROUGH A COMBINED GEOSPATIAL AND NUMERICAL MODELING APPROACH
Extreme rainfall Flooding Impact assessment 2D Flood modeling LiDAR Landsat
2016/12/1
In this paper, we present a combined geospatial and two dimensional (2D) flood modeling approach to assess the impacts of flooding due to extreme rainfall events. We developed and implemented this app...
ASSESSING FLOOD IMPACTS IN RURAL COASTAL COMMUNITIES USING LIDAR
coastal flooding lidar transportation
2016/12/1
Coastal communities are vulnerable to floods from storm events which are further exacerbated by storm surges. Additionally, coastal towns provide specific challenges during flood events as many coasta...
IMPACTS OF TREE HEIGHT-DBH ALLOMETRY ON LIDAR-BASED TREE ABOVEGROUND BIOMASS MODELING
tree aboveground biomass lidar allometric equations simulation regression
2016/11/30
Lidar has been widely used in tree aboveground biomass (AGB) estimation at plot or stand levels. Lidar-based AGB models are usually constructed with the ground AGB reference as the response variable a...
DETERMINING THE IMPACTS OF LAND COVER/USE CATEGORIES ON LAND SURFACE TEMPERATURE USING LANDSAT8-OLI
Land Surface Temperature Tasseled Cap Transformation Istanbul Landsat 8 OLI
2016/11/30
Due to unplanned and uncontrolled expansion of urban areas, rural land cover types have been replaced with artificial materials. As a result of these replacements, a wide range of negative environment...
ASSESSMENT OF FLOODED AREAS PROJECTIONS AND FLOODS POTENTIAL IMPACTS APPLYING REMOTE SENSING IMAGERY AND DEMOGRAPHIC DATA
Floods Climate Change Impacts Climate Change Vulnerability
2016/11/30
Assessing vulnerability and potential impacts associated with extreme discharges requires an accurate topographic description in order to estimate the extension of flooded areas. However, in most popu...
EYE TRACKING TO EXPLORE THE IMPACTS OF PHOTOREALISTIC 3D REPRESENTATIONS IN PEDSTRIAN NAVIGATION PERFORMANCE
3D photorealism eye tracking cognitive workload,
2016/7/8
Despite the now-ubiquitous two-dimensional (2D) maps, photorealistic three-dimensional (3D) representations of cities (e.g., Google Earth) have gained much attention by scientists and public users as ...
Impacts of a Resolution-Pyramid on Gibbs Random Field Classification
Segmentation Texture Classifi cation Multiresolution Hierarchical Spatial IKONOS
2016/1/25
In this paper we describe how to extend the Markov/Gibbs random field model used for texture classification to a multi-resolution
approach in the context of land cover analysis. Our metho...
REMOTE SENSING FOR ASSESSING ENVIRONMENTAL IMPACTS BASED ON SUSTAINABILITY INDICATORS
Satellite remote sensing Spatial databases Interferometric SAR Crop management Sustainability Indicators
2016/1/3
Sustainable development is that which meets the needs of the present without foreclosing the needs or options of the future. Many studies have been published on how to assess sustainability using indi...
TRACKING ENVIRONMENTAL IMPACTS AND HABITAT FRAGMENTATION ON COASTAL PROTECTED AREAS THROUGH OBJECT ORIENTED ANALYSIS.IDENTIFICATION AND CATEGORIZATION OF LINEAR DISTURBANCES IN CORRUBEDO NATURAL PARK (NW IBERIAN PENINSULA)
Monitoring vegetation classification fuzzy logic object context orthoimage
2015/8/19
The increase of tourism in coastal protected areas is potentially one of the drivers of ecosystem fragmentation with the consequent important damages to their biodiversity values. One of the key manag...
SPATIAL AND TEMPORAL ANALYSIS OF FOREST COVERS CHANGE: HUMAN IMPACTS AND NATURAL DISTURBANCES IN BARTIN FORESTS, NW OF TURKEY
Remote Sensing GIS Classification Change Detection Forestry
2015/6/1
During last two decades, Bartin Forests in northwest of Turkey have been exploited by human impacts. Easy access and the abundance of valuable and large diversity forest products have led to higher po...

all Thailand’ shrimp is now produced inlan...
A methodological approach for the evaluation of impacts on sites of geomorphological interest (SGI), using GIS techniques
Geomorphological assets Intrinsic quality GIS Analysis
2015/2/5
This paper proposes a methodological approach for the study of one component of the geomorphological asset: the
intrinsic quality. This approach is derived from the integration of two methodologies d...
