Border politics are a salient component of high international politics. States increasingly building infrastructure to ‘‘secure’’ their borders. We introduce the concept border orientation describe extent which state is committed spatial display capacities control terms penetration its national provides lens through analyze resistance globalization, growing populism, and consequences intensifie...

In recent years, multiple geospatial ontologies have been developed for a wide range of different spatial databases. In addition, the development of volunteered geographic information both challenges and provides opportunities to the traditional authenticated geospatial information. Though volunteered geographic information is typically not as reliable and structured as the authenticated geospa...

Segmentation is one popular method for geospatial data mining. We propose efficient and effective sequential-scan algorithms for higher-order Voronoi diagram districting. We extend the distance transform algorithm to include complex primitives (point, line, and area), Minkowski metrics, different weights and obstacles for higher-order Voronoi diagrams. The algorithm implementation is explained ...

The surge in availability of geospatial data sources, the increased use of crowdsourced maps and the advent of geospatial mashups have brought us to an era where geospatial information is delivered to users after integration from diverse sources. Understanding the provenance of geospatial data is crucial for assessing the quality of the data and addressing whether to trust the information or no...

This article provides an overview of the application of geospatial technologies for disaster and emergency management; themotivebehind this special issue is focusingon the importanceofhighlighting theefforts of geospatial technologies community in the field of disaster and emergency management. This issue provides an insight on the future directions of geospatial technologies for disaster manag...

Linked geospatial data has recently received attention, as researchers and practitioners have started tapping the wealth of geospatial information available on the Web. Incomplete geospatial information, although appearing often in the applications captured by such datasets, is not represented and queried properly due to the lack of appropriate data models and query languages. We discuss our re...

The creation of a National Spatial Data Infrastructure (NSDI) is of growing interest in Rwanda. The importance of NSDI in facilitating access to and use of geospatial data to support decision-making is recognised. Numerous government ministries and institutions in Rwanda produce geospatial datasets of different themes. It is challenging to know what datasets exist and how to access them. Since ...
