What is the role of GIS and remote sensing technology in watershed management with a case study?

What is the role of GIS and remote sensing technology in watershed management with a case study?

The use of Remote Sensing Data for faster assessment of natural resources such as soil, geology, drainage etc. as well as assessment of economic activities through land use and infrastructure of the watershed area is well known. This is also used for monitoring of watershed development at later years.

What is the importance of geographical information system?

Today a well-developed GIS systems are used to protect the environment. It has become an integrated, well developed and successful tool in disaster management and mitigation. GIS can help with risk management and analysis by displaying which areas are likely to be prone to natural or man-made disasters.

Why is GIS important in environmental management?

GIS is a powerful tool for environmental data analysis and planning. GIS stores spatial information (data) in a digital mapping environment. GIS can provide a quick, comparative view of hazards (highly prone areas) and risks (areas of high risk which may occur) and areas to be safeguarded.

What is the role of remote sensing in agriculture?

Remote sensing gives the soil moisture data and helps in determining the quantity of moisture in the soil and hence the type of crop that can be grown in the soil. Soil Mapping: Soil mapping is one of the most common yet most important uses of remote sensing.

How GIS helps in managing watersheds?

Application of GIS in Watershed Management The analytical muscle of GIS, combined with readily available digital elevation data, can be used to automate the watershed modeling process and provide a visual representation of the watershed’s response to existing conditions and proposed improvement scenarios.

What is the application of remote sensing in forestry?

There are many forestry applications that remote sensing can be used for. Some of these applications include terrain analysis, forest management, recultivation, updating of existing forest inventories, forest cover type discrimination, the delineation of burned areas, and mapping of cleared areas.

What is the impact of geographic information systems on environment conservation?

GIS in managing natural resources The major application of GIS in natural resource management is in confronting environmental issues like a flood, landslide, soil erosions, drought, earthquake etc. It also addresses the current problems of climate change, habitat loss, population growth, pollution etc.

How remote sensing is useful in agriculture?

How can remote sensing and geographic information systems help in wetlands conservation?

Recently, remote sensing and Geographic Information Systems tools have been used to assess, monitor wetlands biodiversity, and to promote awareness providing technical support to decision-makers for conservation and sustainable development of these ecosystems.

How can geospatial technologies be used to map wetland resources?

Geographic Information System (GIS) and remote sensing technologies have proven to be useful for mapping and monitoring wetland resources. Recent advances in geospatial technologies have greatly increased the availability of remotely sensed imagery with better and finer spatial, temporal, and spectral resolution.

Can remote sensing satellite data be analyzed with GIS?

High-resolution Remote Sensing (RS) satellite data from 1990 to 2016 of equal intervals of ten years has been processed and analyzed with Geospatial Information System (GIS) environment.

What is Geo-informatics technology?

Geo-informatics technology is basically comprises of 3S component, Remote sensing (RS), Geographic Information System (GIS) and Global Positioning System (GPS).
