Time Series Geodata visualization in Web 2.0
Abstract Many things that happen are having space and time as major dimensions. Visual representation of these datasets and information brings out unique opportunity to identify meaningful trends like Magnitude, Shape, Velocity, Direction etc. In this paper, we present various
Geographical Weighted Regression model for improved bathymetric estimation from multispectral imageries
Abstract There is often a need for making a high-resolution or a complete bathymetric map based on sparse point measurements of water depth. The common practice of previous studies has been to calibrate a single global depth regression model for
Development of OGC WPS for Species Niche Modelling using environmental variables
Abstract Species distribution prediction modeling plays a key role in Bio-diversity research. There are increasing needs for species distribution modeling ranging from basic ecological and biogeography research to routine conservation practices. Currently forest scientists and conservationists are looking for web
A comparative study of performance analysis of MongoDB and PostGIS-PostGreSQL databases for Line Intersection Spatial Queries
Abstract With the increased shift towards GeoSpatial Web Services on both the Web and mobile platforms especially in the user-centric services, there is a need to improve the query response time. This paper attempt to evaluate the performance of an
Semantic Interoperability Model for transforming IFC & CityGML Building Models
Abstract The significance of 3D city modeling and its promising applications in the fields of city planning, cadastral mapping, urban simulations, etc. are progressively increasing. One of the major problems being faced in the applications of 3D city modeling is
