A conceptual model for structuring features in a geographic information system (GIS) is presented. The model includes spatial, thematic, and temporal dimensions and structures attributes and relationships for each dimension to build a feature-based GIs. The model is grounded in an entity-based view of geographic phenomena and requires representation of geographic entities as feature objects in ...
A Geographical Information System (GIS) is used to retrieve and explore the spatial properties of the visual structure inherent in space. The first section of the article aims to gather, compare and contrast existing approaches used to study visual space and found in disciplines such as landscape architecture, urbanism, geography and landscape archaeology. The concept of a visualscape is introd...
This paper presents an overview of GIS certificate programs available through colleges and universities in the United States and Canada. It is argued that by presenting a structured sequence of coursework, GIS certificate programs have begun to address the varied educational goals of both traditional students and non-degree professionals. A survey of certificate programs listed on the World Wid...
Without a department of geography, Harvard University established the Center for Geographic Analysis (CGA) in 2006 to support research and teaching of all disciplines across the University with emerging geospatial technologies. In the past four and a half years, CGA built an institutional service infrastructure and unleashed an increasing demand on geographic analysis in many fields. CGA servic...
GIS eased into geography without much discord until the 1990s, when a flurry of commentaries about the relative merits of GIS made their way into a number of geographic journals. The ensuing decade was marked by varying degrees of friction between GIS practitioners and their critics in human geography. Despite the methodological chasm between the two groups, little discussion of the implication...
Incorporating the temporal element into traditional GIS is a challenge that has been researched for many years and has many proposed solutions. The implemented system “Extended Dynamic GIS” or EDGIS is based on the “geo-atom” and Space Time Point (STP). EDGIS provides a platform for spatiotemporal data representation, storage, and query in order to address the need for a dynamic GIS to manage c...
Background and Objectives: Public health issues and the spread of disease correlate with geography and always have locational aspects.. Therfore, in this study the spatial analysis of malaria disease reports between 2004-2014 in Bam were investigated using geographic information system (GIS). Materials and Methods: In this cross-sectional study, information on positive cases of malaria were ...
