Use of Precipitation Data from Advanced Microwave Scanning Radiometer 2 in the Forecasting of Floods in Assam
Abstract: Flood occurs most commonly from heavy rainfall but it can also result from storm surge associated with a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels. Rainfall in the upstream of a river can also cause inundation in the downstream side of a river. Reliable and timely information is essential for appropriate flood management system. This paper explains the use of precipitation data …

Vegetation Area Monitoring Through NDVI Technique: A Case Study of Dengei Pahad Micro Watershed, Khurda District, Odisha
Abstract: Watershed treatment includes implementation of participatory micro-watershed-based soil and moisture conservation programs and income generation through proper natural resource management areas. This has led to increased productivity and income. Training and holistic management along with aforestation programs has led to reduction of silt flow to the lake. The assessment revealed that land degradation in the drainage basin not only leads to enhanced silt flow into the lagoon but also causes …

Extraction of Drainage Pattern and Watershed from SRTM Data Using GIS Tools: A Case Study
Abstract: This paper proposes a fast and an inexpensive method for delineating the drainage and watershed of a sub-basin. Planning of the water resource management is evolving from simple local-scale problems toward complex spatially explicit regional scale. Such problems have to be addressed with distributed models that can compute runoff and erosion at different spatial and temporal scales. In general, watershed can range from as little as one hectare to hundreds …

The Use of Satellite Imagery in Estimating Aboveground and Belowground Biomass of Aquatic Vegetation, The Food Source of Waterfowl
Abstract: 800x600 In this research we studied the possibilities to estimate the biomass of aquatic vegetation in a shallow lake using IKONOS image. IKONOS-2 image, with one infrared and three visible bands, was obtained on the 19th of August 2005. The study was carried out in the Lauwersmeer (The Netherlands) that Bewick’s swans use as an autumn staging site to forage on the belowground biomass of fennel pondweed. This research gave …

A GIS Based Tool to Digitize Polygon and Line Segments of a Black and White Map
Abstract: In this paper a GIS based tool has been proposed to digitize polygon and line objects throughefficient usage of RGB values of the segments of raster maps. For digitization of polygon,initially a closed loop is drawn inside the polygon segment. Beginning from the initial point ofthe closed loop, eight connected pixels calculation is incorporated to obtain the pointsexisting in between the loop and the actual boundary. The points which exist …

GIS Based Spatial Analysis for Urban Water Supply: A Case of Kedamay Woyane Sub-City, Mekelle City, Ethiopia
Abstract: Access to drinking water supply is one of the universally recognized basic socioeconomic and environmental problems as it is one of the basic needs for human survival. However, this problem is more acute in developing countries like Ethiopia where there is absence and inequity distribution of drinking water access among the society. Nerveless, the problem is more serious in the country’s urban cities like Mekelle city, where the water distribution …

GIS Based Approach for the Identification of Gaps in the Provision of Urban Amenities: A Comparison Between Srinagar and Jammu Urban Centers
Abstract: Urban amenities comprise the infrastructure, goods and services that are needed for the sustenance and growth of urban societies. Rapid urbanization and consequent unplanned growth of cities result in deterioration of infrastructure facilities and natural endowments. The reasons for the uneven distribution of urban amenities in Srinagar and Jammu are spurt urban growth and poor management planning. The paper examines provision of various urban amenities in Srinagar and Jammu cities …

Digital Elevation Model (DEM) Extraction using Google Earth and Terrain Zonum Solutions Online Tool
Abstract: Topographic data or DEM are commonly perceived as providing loaded information for various types of modeling. However, this information severely limited and most users rely on published topographic maps or DEM produced by government agencies. This paper proposes an alternative method of generating DEM by using online source of elevation data which is easier and free. Firstly, the location of the study area identified in Google Earth and marked using …

Identifying Trends in Landuse/Landcover Changes in Hisar Tehsil: A LCM Based Approach
Abstract: Land is a source of all basic human needs, (e.g., agriculture, forest, water supply etc.) which is being continuously depleted by various agents. Urban growth and urbanization are considered as one of the major factors responsible for change in landcover dynamics and depletion of land resources. As compared with other landcover classes such as agricultural land, urban land has smaller area coverage but its impact to the surrounding environment is …

Development of an Integrated System Prototype to Improve Decisions in Land Use Planning and Management in Ethiopia, Hawzen
Abstract: Constitutional land use planning provides a means of legal control over changes in land use and provides an opportunity to allocate land use to areas best suited to that activity. However, since land use planning is not surveying properly and essentially only deals with suggestions to improve land use system. Land use planning and resource management is a challenging task to many developing countries, due to limited technical resource. Currently …

Quantification of River Bank Erosion, Accretion and Its Effect on Land Use: A Case Study of the Ganges (Left Bank) Upstream of Farakka Barrage, Malda District, West Bengal
Abstract: Bank erosion is mainly a physical process of river dynamics that causes threat to the riparian and floodplain structures, engulfs fertile agricultural land, homes, means of livelihood and assets of the people. Along with physical causes, anthropogenic activities disturb the equilibrium of the river dynamics along the river stretch and accelerate the rate of bank erosion. The study focuses to quantify the decadal and mouza-wise erosion and accretion along the …

Evaluating Building Density Analysis Using Geographical Information System
Abstract: In Mekelle city, urban sprawl is continuously expanding to the surrounding hinterland at an alarming rate without considering the inner infill area of the city. Moreover, several numbers of developers and land speculator hold large tract of vacant land. This has resulted because land speculators buy large aggregation lands and develop small part of their plot and keep the land until the price rises up. And this creates low density …
