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 ...
This paper presents a new technique for information access based on a combination of Geographic Information Systems (GIS) and conceptual structures as modeled in relational concept analysis. It is based on the idea that traditional relational databases restrict their data types to linearly ordered scales. Since spatial data are not linearly ordered, they cannot be modeled directly in relational...
Travel diary data (TDD) is an important disaggregate data source for transportation research. It is an example of multi-dimensional data that combines spatial, temporal, and attribute information. A proper representation of TDD can help researchers extract useful information from the data set. Current GIS is mainly designed to handle spatial and attribute data, lacking the representation of tem...
Der Einsatz von Geoinformationssystemen in der Forstwirtschaft durchlebt aktuell einen Wandel. Durch die Konsolidierung der forstlichen Organisationseinheiten und die Vollmechanisierung erwächst mehr und mehr der Bedarf zur Unterstützung der forstlichen Geschäftsprozesse durch Geoinformationssysteme. Diese für den unternehmensweiten Einsatz konzipierten und in andere Business Systeme integriert...

Transportation systems exist to improve individual accessibility. However, emerging applications of GIS in transportation (GIS-T) and intelligent transportation system (ITS) focus on throughput (the amount of system flow) rather than accessibility. Throughput is related but not equivalent to accessibility. Sensitive transportation planning requires rigorous, realistic and tractable accessibilit...
Erin Aigner and Mike Engelmann, University of Oregon. Creating Atlas Graphics. The University of Oregon Geography Department is collaborating in a joint effort with Allan Cartography of Medford, Oregon to design and publish an updated, second edition, Atlas of Oregon. The UO InfoGraphics Lab, in particular, has assumed the primary role in producing maps and related graphics for the Economic Geo...
