GIS in modeling Environment Risk Surface

GIS-based models called Environmental Risk Surfaces (ERS) can be developed using mapped risk elements (e.g. human activities) to examine the spatial relationships between risk elements and biodiversity features. It can spatially identify habitats within low (intact) and high (threatened or disturbed) risk areas, hence helps in selecting conservation sites where the abatement of pressures on biodiversity seems less likely. All risk element features must be spatially mapped on the landscape as points, lines, polygons or raster models. Human-induced landscape features such as urbanized areas, roads, industrial areas, and indicators for human impacts such as population density, can all be inputs to ERS model. Each risk element is assigned an intensity value and an influence distance based on factors such as the likely extent, severity, and reversibility.

Remote Sensing of Wildfire using Unmanned Aerial System

Unmanned aerial system (UAS) equipped with multispectral sensor is a great approach to classify and estimate wildfire damage. The multispectral imagery collected post wildfire events can help to produce a photogrammetry-based digital surface model (DSM) and orthomosaic for object-based classification analysis. Airborne LiDAR data can be used to validate the accuracy of the DSM. Airborne imagery from pre- and post-fire can be used to estimate pre-fire health, post-fire damage, and track the vegetation recovery process. Immediate and long-term post-fire classifications, area, and volume of burned regions can be produced to track the revegetation progress. The UAS-based classification produced from normalized difference vegetation index and DSM can also be compared to the satellite based Burned Area Reflectance Classification.

GIS and Remote Sensing in Paleochannel Delineation

Paleochannels are important sources of groundwater. Radiometrically corrected optical and synthetic aperture radar datasets can be fused and the paleochannels can be extracted from the analysis of this fused output with support of normalized difference vegetative index analysis. Identification and alignment of the identified paleochannels can be validated with geophysical ground measurements (electrical resistivity,conductivity surveys) and historical records such as old wells. It can be seen that high apparent electrical resistivity with corresponding low soil water conductivity values intersects well with the paleochannels identified from the remote sensing data. Presence of meandering scars, crescent-shaped oxbow lakes, and abrupt change in vegetation tone in satellite images also indicates migratory trace of the paleochannel.

GIS and Remote Sensing in Property Tax Mapping

Most city governments depend on the revenue collection from property tax to finance their infrastructure and city operations. A GIS-based tax assessment and management system can help the city government to: asses the total tax collected for a defined area like a ward; compare this against the expected amount to be collected from the ward; re-plan tax amount based on changing urban development plan and new construction; and develop more detailed system focusing on new development areas to improve tax collection. High spatial resolution satellite data integrated with social survey helps to assess the socio-economic status of the population for tax contribution purposes at parcel levels. Satellite images can also be used to nab tax evaders and other fraud related cases.

Remote Sensing in Human Health Application

Remotely Sensing is a vital tool for the estimation of environmental variables of relevance to human health for monitoring, surveillance, and risk assessment. Association studies can be carried out between remote sensing derived environmental data and pathogen activity, host abundance, and disease outbreaks and transmission. Incorporating longitudinal series of RS data into models plays an important role in parameterizing the spatio-temporal process of disease transmission. Satellite images at different scales whether locally with very high-resolution images, or over larger areas at medium or low resolution, can be used in monitoring terrestrial habitats of disease vectors, impact of climate change on infectious disease outbreaks and transmission, global warming and non-infectious diseases, pollutants and health hazards, urbanization and health consequences. Thus the use of remote sensing in healthcare is truly multifarious.

Remote Sensing in Riparian Buffer Monitoring

Riparian and wetland buffers are important for protecting water quality and wildlife but are often nonexistent or degraded by human activities. Remote sensing help monitor changing buffer over time. High spatial and spectral resolution satellite images helps to counter the complexity of mapping hydrology and land cover of riparian buffer zone that exhibits extreme variations in width, length, spatial complexity, soil, and vegetation cover. The vegetation structural and physical form parameters that include tree height, water bodies, bare ground, streambed width, bank full width, riparian zone width, vegetation overhang, bank condition, bank slope, and bank profile can be easily mapped. LiDAR data can provide topographic derivatives and multidimensional vegetation structure.

Remote Sensing in Ground Water Quality Assessment

Groundwater is the major alternate source of domestic, industrial and drinking water supply. Remote sensing in conjunction with GIS offers great potential to determine depth to water table and hydrological conditions of vadose zone. The land use map, geological and soil map can be created for correlation between land use, geological formations, and soil types to understand the source of natural pollution that can lower the ground water quality. Thematic maps can be prepared for the physio chemical properties data of the ground water obtained from the samples collected from borehole wells and by using spatial interpolation techniques, these maps can be overlayed to obtain the ground water quality map. And finally, the mapping can be coded into potable and non-potable zones.

Remote Sensing in Weather Forecasting

Remote sensing provides information about the state of the Earth‐atmosphere system and its components in an area‐wide and continuous manner. It can measure the surface radiation value, atmospheric temperature, wave conditions and observe wind patterns and speed, detect wave currents and the chemical concentration in the atmosphere. The images of cloud systems enable forecasters to locate and monitor the movements of storms. For e.g. to record and interpret water vapor carried by the radiations, the intensity of the radiation received at the sensor depends on the amount of water vapor in the mid and upper atmosphere. If the air is moist, it appears bright to the sensor and if dry, it appears dark, thus predict the rain areas.

Remote Sensing in identifying CBM Sweet Spot

Coalbed methane is an important source of clean fossil-fuel energy which is now in demand. Remote sensing techniques can help identify the geological structure at the surface of the earth as a bench-mark in determining the CBM sweet spot. Lineament is one of the geological structure indications of the activity. DEM data help in delineating lineaments and produce fracture density map. It can also be used to identify the characteristics of higher-producing coal, gas content and fracture permeability. CBM sweet spot is an area that has a high value of fracture permeability and the trend of regional fracture direction obtained from DEM data can delineate CBM sweet spot.

Remote Sensing in Gas Flaring Estimation in Oil & Gas Operations

Flaring, or the combustion of petroleum products into the open atmosphere, is potentially a major source of hazardous air pollution. Remote sensing provides a means to monitor flaring activities, as multi-spectral satellite imageries are able to detect thermal anomalies. It provides information on flaring sites localization, gas emitted volumes over a period, consumption of CH4 and release of CO2. Gas flares typically operate at temperatures >1450 K, their peak spectral radiant output occurs in the SWIR spectral region, centered around 1.6 µm, which is the most suitable spectral for investigation. On the other hand, when sensors not able to acquire information in this region, the MIR bands (centered on 3.5 µm) are the most used.

Remote Sensing in Geothermal Potential Zone Mapping

Geothermal energy is an important component of green energy. At the earth's surface hot springs and fumaroles are evidence of geothermal zones and Remote Sensing plays an important role in mapping surface deformation, gaseous emissions, mineral mapping, heat flux measurements, temperature mapping and geobotany. Search for areas of rocks altered by hydrological action using satellite images can identify thermal fluids being discharged along faults. Thermal sensors can measure surface thermal properties which are an indicator of geothermal resources. Temperatures can also be obtained using multispectral imagery acquiring land surface temperature (LST) values. The gravimetric anomalies, such as the Bouguer anomalies also help to identify potential areas due to their relationship with aquifer zones.

Remote sensing for Ecology

Remote sensing is used to measure spatial changes in ecological conditions. Remote sensing imagery can be used to detect ecological status in various ranges because it measures reflected radiation of the earth’s surface and hence can detect different components of an ecosystem such as soil, vegetation and open water. A number of remote sensing indices have been created to quantify ecological status. Remote sensing is of value to a nearly continuous measurement of spatial distributions of ecological conditions and provides measurement metrics of the ecological processes. Besides the benefits in cost and operation, the satellites have two obvious advantages in applications, i.e., global surveying and increased revisit frequency. Airborne LIDAR remote sensing is also used for biodiversity science and conservation.
