Drinking water supply and sewerage system designing and reconstruction projects are being extensively conducted in Azerbaijan Republic. During implementation of such projects, collecting large amount ...
SPATIOTEMPORAL DYNAMICS OF SURFACE WATER EXTENT FROM THREE DECADES OF SEASONALLY CONTINUOUS LANDSAT TIME SERIES AT SUBCONTINENTAL SCALE
Landsat time-series seasonally continuous surface water dynamics flooding dynamics Murray-Darling Basin Australia competing water demands drought random forest long term trends water river basin water management
2016/11/30
Surface water is a critical resource in semi-arid areas. The Murray-Darling Basin (MDB) of Australia, one of the largest semi-arid basins in the world is aiming to set a worldwide example of how to ba...
Integrated use of spatial data and learning algorithms to detect water quality trends
Integrated spatial data learning algorithms detect water quality trends
2016/5/20
This paper presents the first results of a study which investigates river basin water quality management based on the ability of GIS to integrate different data sources into a common geographical data...
A RAPID METHOD FOR WATER TARGET EXTRACTION IN SAR IMAGE
Synthetic Aperture Radar Imagery Water Target Automatic Recognition Grey Morphology Nonlinear Filter
2015/12/23
For the inherent speckles in SAR imagery, the processing of object extraction becomes more difficult. Using the traditional target extraction arithmetic for optical imagery, we can not get ideal resul...
A Study of GIS-SD Based Temporal-Spatial Modeling Spatial and Temporal Patterns of Global H5N1 Outbreaks of Water Quality in Water Pollution Accidents
Temporal Spatial Simulation Pollution Decision Support Hydrology
2015/12/1
In this paper, the one-dimension river quality system dynamics model was applied to the water quality simulation, and the conceptual GIS-SD frame was constructed. Based on the component GIS and system...
Water level and volume estimations of the Albano and Nemi lakes (central Italy)
Albano lake Nemi lake Colli Albani DTM airborne laser survey bathymetric survey GPS RTK
2015/9/1
In April 2006 an airborne laser scanning (LIDAR) survey of the Albano and Nemi craters was carried out to obtain a high resolution digital terrain model (DTM) of the area. We have integrated the LIDAR...
WFI/CBERS imagery simulation for understanding water pathways from Amazon River to the floodplain
WFI camera floodplain monitoring
2015/2/4
This paper describes an experiment performed to simulate WFI/Camera spatial features using a TM-Landsat digital
mosaic re-sampled to 258 m x 258 m, 100 m x 100 m resolution. The re-sampled mosaic and...
MONITORING AND ANALYSIS OF WATER POLLUTION USING TEMPORAL GIS
Moving objects temporal GIS temporal databases interpolation water pollution oil spill
2015/2/3
Water pollution caused by oil spills is a typical hazard scenario in which the understanding of object movement—here that
of the oil spill—may be vital for risk minimization. Oil spills do not only p...
HYDROLOGICAL MODELS FOR THE ASSESSMENT OF IMPACTS OF INFRASTRUCTURE ON WATER-DRIVEN GEOMORPHOLOGICAL PROCESSES
Predictive modelling watersheds dynamic processes erosion land cover soil conservation
2015/2/3
The construction of roads and motorways implies a variety of environmental impacts on landscape features. Some of those features are essentially static and impacts on them can be assessed using straig...
