The present study performs landcover modelling using the SLEUTH model. The urban land use changing factors are calibrated to predict the Land Use Land Cover (LULC) for a densely populated and developing smart city, Prayagraj, India. This research aims to use the SLEUTH model for simulating the future urban growth with the help of historical LULC (1...
Article
Spatial Data Infrastructure (SDI) is a framework of geospatial data, metadata, and users that primarily function for the production and sharing of large geospatial data. Metadata refers to “data about data” and the metadata related to spatial data contains information like projection, scale, resolution, reliability, data provider, and distribution...
Chapter
An innovative approach to design, develop and implement an interoperable Spatial Data Infrastructure (SDI) for health sector (acronym OpenSDI4Health) based on National Spatial Data Infrastructure (NSDI) of India and using Open Source Geospatial Resources (OSGR) is developed. The framework is designed with six core components, namely spatial data, m...

Flood is a catastrophic natural disaster event that is immensely threatening and affecting ecosystems as well as human lives all over the world. Flood frequently occurs in Indian districts during the monsoon season. Districts situated near the rivers are more prone to the flood risk. It is not possible to completely eliminate the flood risk, but it...

Full-text available
Using the Geographic Information System (GIS) technology, transportation and network analysis has become a straightforward application. An underlying problem in transportation and network analysis is to find optimal paths between different locations from sources to destination on a network. Sometimes this optimal path between source to destination...

Remote sensing is a popular technique that is using in the mapping and monitoring of earth features. Early remote sensing was predominantly passive, i.e. it depends upon the sun for energy. Till the last decade, optical imaging is mainly used in remote sensing works. Over the time, significant innovations and improvements have been made in the acti...

Land management in the limited environment of city regions with immense population pressure is a challenging task. To achieve the goal of sustainable smart cities, reliable spatial information needs to be incorporated in land governance policies. In this study, Landsat 8 satellite bands were processed to derive the land use characteristics which ar...

Urbanization is occurring at a fast rate in India. Population residing in urban areas was 11.4% according to the Census of 1901. This percentage has gradually increased to 31.16% according to the Census of 2011. Conversion of agricultural land into non-agricultural uses is the major side effect of urbanization. The objective of this paper is to ide...
