A GIS Approach to Identify Potential Zones of Polymetallic Nodules in The Indian Ocean Region
Abstract: Mankind’s quest for metals has been growing steadily and has resulted in expanding his search beyond land, that is, in the oceans. Being in the dissolved form, metals are also formed in the ocean in the form of polymetallic nodules. They are submarine rock concretions formed of concentric layers of Iron and Manganese hydroxide around a nucleus. Nodules contain manganese and iron, nickel, copper, cobalt, lead, molybdenum, cadmium, vanadium, titanium, …

A Contribution to the Study of Geographical Displacement of Crime using GIS–Kings Cross, London
Abstract: Displacement of crime is the specter that haunts crime prevention studies, in that, the crime problem does not go away but shifts from one location to another. The fact that crime is not reduced in an area but rather moves around means that trying to change the situation and circumstances surrounding the targeted area may not fully reduce crime. Research that has been previously carried out into the study of …

Change Detection of Land Use/Land Cover in Upper Ganga Canal Command, India, Using Arc-GIS Tools
Abstract: The rapid growth of urban population in India is a cause of concern among the country’s urban and town planners for efficient urban planning. The drastic growth of urban areas has resulted in sharp land use and land cover changes. In recent years, the significance of spatial data technologies, especially the application of remotely sensed data and geographical information system (GIS) has been widely used. The present study investigates the …

Effect of Dust Storm on Phytoplankton Productivity in Arabian Sea
Abstract: Dust storm plays an important role as it triggers phytoplankton in the ocean by adding nutrients. In the present study, an attempt has been made to understand the role and relation between dust storm and phytoplankton concentration. Chlorophyll-a concentrations are an indicator of phytoplankton abundance and its biomass. Satellite data gives daily information on Chlorophyll-a concentration and so as phytoplankton abundance in the ocean as well as information about dust …

GIS Based Storm Water Management System for Rapidly Growing Urban Areas: A Case Study
Abstract: Rapid urbanization and changing land use have resulted in changes in the quality and quantity of urban runoff. A correlation between changes in land use and characteristics of urban runoff has been established. Therefore, there is a need to evolve a suitable dynamic system for stormwater management of rapidly growing urban areas. This paper demonstrates the use of remote sensing combined with GIS to model and manage stormwater in a …

Image Segmentation by Grouping Pixels in Color and Image Space Simultaneously using DBSCAN Clustering Algorithm
Abstract: In this paper, the authors propose a technique for image segmentation by integrating the spatial connectivity and color features of pixels. Taking into account that an image can be considered as a dataset in which each pixel has a spatial location and a color value, color image segmentation can be obtained by clustering these pixels into different groups of coherent spatial connectivity and color. To discover clusters in spatial databases …

Segmentation Methods for Images: A Systematic Review
Abstract: Image segmentation is the initial operation in image processing and computer vision to extract a region of interest from a still image or a sequence of images (video). Segmentation is the key operation to perform a number of applications today. Different supervised and unsupervised evaluation methods have been used for segmentation for numerous applications, but still it is a challenging task to identify which method is more accurate. This paper …
