1. The document compares the use of Maximum Likelihood Classification (MLC) and Sub Pixel Classification (SPC) techniques for coastal biomass mapping using Landsat satellite imagery with 30m resolution and QuickBird imagery with 2.4m resolution.
2. Analysis showed that MLC failed to separate important vegetation classes when applied to Landsat data, while SPC successfully overcame mixed pixel problems and separated saltbush and algae vegetation classes.
3. SPC was found to be more time and cost effective than MLC for coastal biomass mapping using medium resolution satellite data over large areas.
Two way data sharing between government agencies and community groups is essential to ensure effective delivery of the Water Framework Directive and many other statutory and environmental management objectives. Achieving this will require some joined-up thinking and investment in strategic infrastructure, particularly for the community groups who aren't currently covered by the INSPIRE directive.
The Rivers Trust as the umbrella body for the rivers trusts movement are key players working towards this aim.
This project used aerial and satellite imagery to assess rangeland condition and monitor trends in Kansas. Researchers aimed to characterize rangeland using spectral measurements and assess how grazing practices impact biophysical and spectral responses. Findings could help ranchers make decisions, map land use at multiple scales, and identify areas needing remediation, with the goal of determining if remote sensing can effectively evaluate rangeland condition and change over time.

Three presentations from session 4 of the 2017 Greater Mekong Forum on Water, Food and Energy which took place from Oct. 25-27 at the Inya Lake Hotel in Yangon, Myanmar. Mapping the footprint of Reservoirs in the Mekong region was hosted by SERVIR-Mekong and the Asia Disaster Preparedness Center. Dam construction along the Mekong and neighboring river systems is impacting communities and ecosystems throughout the region. Hundreds of additional dams have been proposed which will further impact communities and ecosystems in the region. To better understand these impacts, and based on feedback from stakeholders at last year’s forum, SERVIR-Mekong has refined an online tool for modeling the inundation of proposed dams. The tool has also been used to compile a dataset of the extent of all existing and planned dams along the region’s large, transboundary rivers. The tool, which requires no proprietary software to access and use, can also model the inundation area of hypothetical dams at any location along the region’s rivers in the region. This session will present the latest version of the online tool and the reservoir data set for the Mekong river followed by participatory discussions to identify how these and related resources can best address such topics as impacts on river hydrology, flood and drought mitigation, and large scale forest conversion.

This document discusses how data science and machine learning can help achieve more sustainable mineral exploration. It outlines several challenges with conventional exploration methods and provides examples of how non-invasive exploration technologies like spectral imaging can help. These technologies allow for rapid, multi-scale mapping of material characteristics in a way that is non-invasive, versatile and can provide automated real-time processing. The document also discusses using these methods from drones to map inaccessible areas and for environmental monitoring, as well as the need for multimodal 3D processing and potential for autonomous drone swarms.
The document summarizes research using the RivWidth algorithm to calculate stream channel widths in the Ohio River and its tributaries above Warsaw, Kentucky from 2001 United States Geological Survey National Land Cover Dataset raster data. The RivWidth algorithm, developed by Tamlin Pavelsky and Laurence Smith in 2008, was applied to obtain stream width values and locate stream centerlines.

Important restoration planning practices and items commonly overlooked when designing, constructing, monitoring and maintaining ecological restoration projects will be discussed.
The document discusses natural capital accounting efforts in the Czech Republic, which have focused on developing extent accounts as well as biophysical and monetary accounts for carbon sequestration, water purification, and nature-based recreation ecosystem services. It also tested applying value transfer approaches and a water retention model to ecosystem accounting. The natural capital accounting work in the Czech Republic has been supported by the MAIA project.
The document discusses piloting marine ecosystem accounts in Finland. It links species and habitats to ecosystem services to assess ecosystem extent and condition. Species distribution models and inventory data are used to map the geographical distribution and projected extent of species providing ecosystem services. The condition of these species is estimated by comparing projected versus realized distributions and assessing impacts from human activities. This information is used to develop initial biophysical marine ecosystem accounts, demonstrating the integration of extent and condition for accounting purposes. The approach provides a way forward for including ecosystem condition in marine accounts.

This document summarizes a study that used GIS spatial analysis and multi-criteria evaluation to identify areas in the East Riding of Yorkshire, UK that are most sensitive to environmental impacts from landfill leachate and to identify the three landfill sites that pose the highest risk. The methodology weighted factors like proximity to residential areas, protected sites, and water sources to produce a sensitivity map. The analysis found 11 high-risk landfill sites, and identified Carnaby (Moor Lane), Gransmoor Quarry Site A, and Thorneholme as having the highest pollution potential due to size, waste types, and nearby water sources and boreholes.
Rangeland Carbon Sequestration In Californiaandrewfynn
There are several methodological elements that could be combined to create a balanced rangeland carbon sequestration protocol, including direct soil sampling, spectroscopy methods, eddy covariance towers, remote sensing, and ecosystem models. A successful protocol may have a simple front-end using visual indicators and some direct sampling, combined with a sophisticated back-office using modeling, analysis, and new technologies to drive adoption rates. Both soil carbon and tree carbon should be considered given their interactions and impacts on ecosystem functions.

The document compares pore characteristics of soil aggregates from conventional row-crop agriculture (CT) and native succession vegetation (NS). X-ray microtomography was used to scan aggregates from both land uses. Analysis found that CT aggregates had significantly greater porosity and more complex pore networks than NS aggregates. However, NS aggregates had larger pores and pore networks that were more widely spaced, indicating greater variability in accessibility for air, water, and microbes.
This document summarizes research assessing ecosystem services over large areas in Scotland. Satellite data was integrated with other data to model various ecosystem services indicators at high spatial resolution, including net primary productivity, crop production, livestock density, water services, nutrient retention, and biodiversity. Hotspots with high levels of multiple ecosystem services were identified. Tools were developed to help stakeholders explore tradeoffs and advise on sustainable land management and land use change options based on ecosystem services priorities and spatial context. Limitations included lack of data on biodiversity's role and need for frequent monitoring to assess change over time.
Interpretation of Landscape Values, Typology and Quality Using Methods of Spa...Universität Salzburg
The main result of this work consists in determined ecological significant areas of habitats that are under protection´s system of Natura 2000 Sites. The patches quantification of habitats is the partial result that influences process of determination of ecological significance. The interpretative process examines land cover patches by the set of landscape metrics for the area, size, density and shape (NP, PD, MPS, PSSD and MSI). The output values could express a spatial processes in the landscape, such as perforation, dissection, fragmentation, shrinkage or attrition. The final ecological significance of the study area-Sitno Natura 2000 site-is at degree 3, what means that the area is represented by moderately significant land cover patches-habitats. It indicates the same value as the one at the initial level. According to the value of the ecological significance, the study area has been diversified into three zones, where each one indicates specific level of conservation. The zones and the final degree of the ecological significance of habitats are retroactively compared to historical and cultural human development that started in this area as early as in 1st century BC. Theoretically, such a long period of intense human impacts on the local environment should completely destroy natural environment. Nevertheless, this area demonstrates rather good natural ecosystems conditions and well functioning ecological processes within the habitats. The human impact is now observed only in small range of size not more than 1,50% from total area of Sitno Natura 2000 Site. It can be explained, first, by low population density within the study area comparing to other EU areas, secondly, by accurate usage of the living area by the local population in general, and thirdly, by high resilience of the elements of landscapes towards any human impacts.

Studies on seasonal variation of ground water quality using multivariate anal...eSAT Journals
Abstract
In this study the seasonal variability of groundwater quality parameters in Bidar urban and its industrial area are investigated. Three
water samples each from 35 wards were collected and subjected for physico-chemical analysis. Average of the three samples represents
each ward data. Analysis was done for pre-monsoon and post-monsoon seasons of the years 2009, 2010 & 2011. Seventeen physicochemical
parameters viz., pH, total hardness, calcium, magnesium, chloride, nitrate, sulfate, total dissolved solids, iron, fluoride,
sodium, potassium, alkalinity, manganese, zinc, dissolved oxygen & total solids were analyzed. Factor analysis is applied on the data
set to investigate the origin of the water pollution sources. FA yielded three factors for each season (combined pre-monsoon &
combined post-monsoon) with 62.8% and 61.6 % total variance respectively; in addition FA identifies anthropogenic factor (i.e.,
industrial, urban sewage and agricultural drainage) and natural factor (top soil mixture with water and percolation, weathering of
ground strata) as latent pollution sources. Hierarchical cluster analysis grouped 35 sampling stations of Bidar urban into three
clusters, i.e., relatively less polluted (LP), and moderately polluted (MP) and highly polluted (HP) sites, based on the similarity of water
quality characteristics.
Keywords: Bidar urban & its industrial area, Ground water quality, Correlation coefficients, Factor analysis, Cluster

Remote sensing and GIS are closely linked technologies. Remote sensing can be used to efficiently update GIS data layers, and GIS can improve the interpretability of remote sensing data. A widely used land use/land cover classification system developed by the USGS meets criteria such as having at least 85% accuracy and being applicable over large areas. A case study of Hyderabad City in India found rapid urban growth is resulting in loss of agricultural land and environmental issues, demonstrating the need for accurate and regular land use/land cover data.
This document discusses a project to map coastline change along Great Britain over 38 years (1984-2022) using satellite imagery. The project aims to create a database of coastline positions along Britain's 17,000km coastline at 10m resolution. The challenges include processing over 4TB of satellite data to automatically extract waterlines and integrate auxiliary data to produce consistent tide lines. The project brings together the British Geological Survey and ARGANS Ltd to provide coastal change evidence to inform coastal management and help communities adapt to flooding and erosion risks.
The document discusses using life cycle assessment (LCA) as a tool for designing more sustainable cities. LCA can help address environmental problems by assessing the full life cycle impacts of city infrastructure and design. The document presents an LCA of natural gas distribution networks in neighborhoods with varying densities. Results show the environmental impact is four times higher in a low-density neighborhood compared to medium and high-density neighborhoods, mainly due to differences in network length. LCA is presented as an appropriate tool for guiding urban ecodesign and decision-making by providing a comprehensive view of environmental impacts.
IRJET- Soil Property Mapping of Kazhakuttam Ward using Geographic Information...IRJET Journal
1. The study mapped soil properties of Kazhakuttam ward in Trivandrum, India using a geographic information system (GIS). Soil samples were collected from 10 locations and tested for properties like particle size, moisture content, density, and liquid/plastic limits.
2. Thematic maps of each soil property were created in GIS to show spatial variations across the ward. Properties varied significantly from place to place, with sandy soil near coastal areas and clayey soil farther inland.
3. Mapping soil properties in GIS provided a database for estimating properties where no samples were collected. This reduces costs and time for soil investigations, benefiting construction in the area. The analysis demonstrated GIS's ability

An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The stage 3 analysis of the landscape aggregates three
factors into a three digit code of “Distinctiveness”,
“Restoration Potential” and “Condition”. Using this
code, the end user will not only see “sensitive” areas,
but also understand why and how.
15. Stage 3

These were then stacked upon each other giving one composite
value (Figure 3). Thus providing a quantification to inform planners
and decision makers. Only Habitats with a distinctiveness of
medium and high were analysed
