Abstract Advancement in technology has made a new sphere of geospatial exploration. Application geoinformatics Landuse and Landcover study quantitative analysis most clear. Urbanization process is an inevitable factor developing countries like India. Last 30 years eastern India also been changed itself terms urban development. Kolkata Bhubaneswar are two important cities where growth taken plac...

Flood occurs as a result of rising global temperatures, more precipitation, increased runoff, and an increase in the rate urban flooding. The goal this research is to calculate flood risk assessment selected catchment Nigerian metropolis Uyo. Secondary data were obtained from Landsat images study area using correlational design. Using supervised categorization landuse area, watershed pattern, l...

We propose a methodology for defining urban markets based on builtup landcover classified from daytime satellite imagery. Compared to defined using minimum thresholds nighttime light intensity, imagery identify an order of magnitude more markets, capture India’s population, are realistically jagged in shape, and reveal variation the spatial distribution economic activity. conclude that data pro...

Landscape structure in a forest mosaic changes with spatial scale (i.e. spatial extent) and thresholds may occur where structure changes markedly. Forest management alters landscape structure and may affect the intensity and location of thresholds. Our purpose was to examine landscape structure at different scales to determine thresholds where landscape structure changes markedly in managed for...

The critically endangered Sumatran tiger (Panthera tigris sumatrae Pocock, 1929) is generally known as a forest-dependent animal. With large-scale conversion of forests into plantations, however, it is crucial for restoration efforts to understand to what extent tigers use modified habitats. We investigated tiger-habitat relationships at 2 spatial scales: occupancy across the landscape and habi...

The Landuse / Landcover system espoused by almost all Organisations and scientists, engineers and remote sensing community who are involved in mapping of earth surface features, is a system which is derived from the united States Geological Survey (USGS) LULC classification system. The application of RS and GIS involves determining of homogeneous zones, trend analysis of land use integration of...

In recent years, elk have begun recolonizing areas east of the Rocky Mountains that are largely agro-forested ecosystems composed of privately owned land where management of elk is an increasing concern due to crop and forage depredation and interspecific disease transmission. We used a Geographic Information System, elk use locations (n = 5013), random locations (n = 25,065), discrete-choice m...

Applications of the Soil and Water Assessment Tool (SWAT) model typically involve delineation of a watershed into subwatersheds/subbasins that are then further subdivided into hydrologic response units (HRUs) which are homogeneous areas of aggregated soil, landuse, and slope and are the smallest modeling units used within the model. In a given standard SWAT application, multiple potential HRUs ...

Located in northwestern Botswana and fed by the Okavango River originating in Angola's western highlands, the Okavango Delta is the world’s largest inland delta. The floodwaters require approximately nine months to flow from the source to the bottom of the Delta due to the extremely low topographic relief. During the peak of flooding, the delta’s area can expand to over 16,000 square kilometers...
