RETRIEVAL AND MAPPING OF HEAVY METAL CONCENTRATION IN SOIL USING TIME SERIES LANDSAT 8 IMAGERY
Soil heavy metal Time series Remote sensing imagery Landsat Retrieval Model selection
2018/5/14
Heavy metal pollution is a critical global environmental problem which has always been a concern. Traditional approach to obtain heavy metal concentration relying on field sampling and lab testing is ...
BENTHIC HABITAT MAPPING AND BIODIVERSITY ANALYSIS IN THE PRIMEIRAS AND SEGUNDAS ARCHIPELAGO RESERVE
Very high resolution remote sensing Object-based image classification
2015/5/7
The Primeiras and Segundas Archipelago Reserve is a recently established marine protected area, the largest in Africa, located in the waters of Northern Mozambique. This protected area is of signifi...
Mapping the topsoil pH and humus quality of forest soils in the North Bohemian Jizerské hory Mts. region with ordinary, universal, and regression kriging: cross-validation comparison
Black Triangle digital soil mapping geostatistics map accuracy
2015/3/9
North Bohemia belongs to one of the most heavily industrialized and polluted regions in Europe. The enormous acid deposition which culminated in the 1970s has largely contributed to the accelerated ac...
Digital soil mapping from conventional field soil observations
field soil description fuzzy k-means pedometrics regression-kriging terrain
2015/3/9
We tested the performance of a formalized digital soil mapping (DSM) approach comprising fuzzy k-means (FKM) classification and regression-kriging to produce soil type maps from a fine-scale soil obse...
Building soil spectral library of the Czech soils for quantitative digital soil mapping
diffuse reflectance spectroscopy digital soil mapping soil spectral library
2015/3/3
Spectral libraries are the data archives of spectral signatures measured on natural and/or man-made materials. Here, the objective is to build a soil spectral library of the Czech soils (SSL-CZ). Furt...
Mapping soils using the fuzzy approach and regression-kriging case study from the Považsky Inovec Mountains, Slovakia
fuzzy k-means regression-kriging digital landscape data grid interpretation spatial distribution soil classification
2015/1/30
The paper introduces a method of digital mapping of spatial distribution of soil typological units. It implements fuzzy k-means to classify the soil profile data (study area from the Považsky Ino...
Object-oriented Fuzzy Analysis of Remote Sensing Data for Bare Soil Brightness Mapping
remote sensing soil colour digital soil mapping fuzzy analysis fuzzy membership function
2015/1/28
Remote sensing data have an important advantage; the data provide spatially exhaustive sampling of the area of interest instead of having samples of tiny fractions. Vegetation cover is, however, one o...
Soil mapping approach in GIS using Landsat satellite imagery and DEM data
Soil survey soil mapping soil classification GIS DEM satellite data
2010/9/14
The objective of this study was to create base soil survey maps of the studied lands using Landsat satellite imagery and Digital Elevation Model (DEM) data in a GIS framework. Specific goals were to g...
An appraisal of landuse and landcover mapping in Nigeria
Landcover landuse remote sensing biodiversity environment
2009/3/4
Land use and landcover change have emerged as a global phenomenon and perhaps the most significant regional anthropogenic disturbance to the environ-ment, especially in the 20th century. Rapid ur...
Lithological Mapping of the Unsaturated Zone of a Porous Media Aquifer to Delineate Hydrogeological Characteristic Areas：Application to Israel's Coastal aquifer
GIS mapping Unsaturated zone/vadose zone lithology confined aquifer phreatic aquifer
2009/3/3
With water quality steadily decreasing, decision-making with regard to water supply must improve aquifer management models, which are based upon various assumptions. Amongst these are assumptions c...
