Geospatial information plays a vital role in today’s decision support system. Geospatial objects, the constituents of geospatial information, have both spatial representation and non-spatial/attribute values. These objects are represented as point, poly-line and polygon in maps. Though, the objects are crisply represented in geospatial maps, their region of influence depends on various factors ...

Knowledge on spatial distribution of land cover and land use is extremely important for solving applied problems in many domains such as agriculture/food security, environmental monitoring, and climate change. Geospatial data including satellite imagery play an important role since it can provide regular, consistent and objective information. Identifying geospatial patterns and quantifying chan...

Land-titling programs in low-income nations have provided the opportunity to leverage the application of geospatial technology to support low-cost titling and expedite implementation. The spatial data acquired and managed in land administration is often a cornerstone of a broader spatial data infrastructure (SDI) in a country. Geospatial technology use in land titling is often viewed narrowly i...

Three-dimensional (3D) GIS is gaining more and more acceptance among both scientists and the general public. Though powerful in data visualization, 3D GIS is comparatively weak in geospatial analysis. In order to enhance 3D GIS’s analysis capability, we present an approach for integrating geospatial processing services into 3D GIS. The architecture of our approach contains four layers which are...

Why are notions like semantics and ontologies suddenly getting so much attention, within and outside geospatial information communities? The main reason lies in the componentization of Geographic Information Systems (GIS) into services, which are supposed to interoperate within and across these communities. Consequently, I look at geospatial semantics in the context of semantic interoperability...

Cornell University Geospatial Information Repository, CUGIR, is a Web-based repository providing free access to geospatial data and metadata for New York State. Access is enhanced by transforming and re-purposing geospatial (FGDC) metadata into DC-RDF, Metadata Object Description Schema (MODS) and MARC 21 that is rendered in XML, HTML, SGML, and ASCII text on-thefly. Although libraries today ar...

A large family of real-world applications are influenced by geospatial features and known relationships between them. Also, a very large volume of geospatial data is currently available from different sources, prepared for different applications, and with different levels of uncertainty. This paper presents a brief analysis about spatial, thematic, technical and temporal aspects of uncertainty ...

Most civil engineering tasks require accessing, surveying and modifying geospatial data in the field and referencing this virtual, geospatial information to the real world situation. Augmented Reality (AR) can be a useful tool to create, edit and update geospatial data representing real world artifacts by interacting with the 3D graphical representation of the geospatial data augmented in the u...

In this paper, we propose an approach to semantically retrieve geospatial objects within an Intranet by means of their metadata. It consists of structuring a semantic repository in order to provide the inclusion mechanisms of distributed data to be retrieved, as well as the extraction of those geospatial objects with respect to their conceptual similarity. The similarity measure is based on a c...

Today’s organizations often gather large quantities of geographic and geo-spatially referenced data to support business decision-making. While there has been research into the significance of user characteristics on decision-performance when working with geospatial data, there is conflicting knowledge on the necessity of the geospatial reasoning ability of the decision-makers to ensure that eff...
