The functionality of spatial process analysis is the foundation of GIS’s comprehensive application . To realize such a goal. it is desirable that not only the data model of GIS can represent the datasets needed by spatial process models, but also GIS is able to do multitemporal spatial analysis. But most of current GISs are static in essence, they cannot represent temporal information and tempo...

We begin by congratulating Professors Yu and Meng on an outstanding paper, and thanking Professor Levine for giving us the opportunity to discuss their work. Our discussion focuses mainly on the GIS & ASIS algorithms. Section 1 concerns the relationship between the GIS and sandwich algorithms. In Section 2, we consider a family of toy GIS algorithms based on the bivariate normal distribution, a...

Advances in geographic information system (GIS) technology, developed by geographers, provide new opportunities for environmental epidemiologists to study associations between environmental exposures and the spatial distribution of disease. A GIS is a powerful computer mapping and analysis technology capable of integrating large quantities of geographic (spatial) data as well as linking geograp...

This study aims to develop a social media GIS (Geographic Information Systems) specially tailored to information exchange between regions. The conclusions of this study are summarized in the following three points.(1) Social media GIS is a geographic information system which integratesWeb-GIS, SNS and Twitter into a single system. A social media GIS was conducted for the collection of regional ...

let $p$ be an analytic function defined on the open unit disc $mathbb{d}$ with $p(0)=1.$ the conditions on $alpha$ and $beta$ are derived for $p(z)$ to be subordinate to $1+4z/3+2z^{2}/3=:varphi_{c}(z)$ when $(1-alpha)p(z)+alpha p^{2}(z)+beta zp'(z)/p(z)$ is subordinate to $e^{z}$. similar problems were investigated for $p(z)$ to lie in a region bounded by lemniscate of bernoulli $|w^{2}-1...

This paper explores the use of World Wide Web (WWW, or simply Web) as a means of designing and developing a toolkit, GeoV&A, for interactive 3D visualization and analysis of existing 2D Geographical Information System (GIS) data. The toolkit is mainly composed of two parts. One is a 3D visualization tool and the other is a 3D analysis tool, including profile creation, viewshed analysis, volumet...
