In physics, objects can be divided into rigid and soft objects according to the object deformation capacity. Similarly, geo-object can also be classified into rigid geo-objects (e.g., building, urban) and soft geo-objects (e.g., mudflow, water, soil erosion). There are three types of approaches for 3D GIS modeling, i.e., surface-based, volume-based, and hybrids in terms of geometry. These appro...

World-system dynamics are re-conceptualized as inter-societal systems with some de-emphasis on the notions of core, periphery, and semi-periphery. This tri-part division has been useful in forcing sociology to rethink macrolevel sociological analysis and in establishing the importance of considering inter-societal systems as a fundamental unit of human social organization, but this Weberian-lik...

Geosynchronous Synthetic Aperture Radar (GEO SAR) is a possible next generation SAR system, which has the excellent performance of less than one-day revisit and hundreds of kilometres coverage. However, Radio Frequency Interference (RFI) is a serious problem, because the specified primary allocation frequencies are shared by the increasing number of microwave devices. More seriously, as the hig...

With their increasing availability and quantity, remote sensing images have become an invaluable data source for geographic research and beyond. The detection and analysis of spatial patterns from such images and other kinds of geographic fields, constitute a core aspect of Geographic Information Science. Per-cell analysis, where one cell’s characteristics are considered (geo-atom), and interac...

Protocadherin 19 (Pcdh19) is an X-linked gene belonging to the protocadherin superfamily, whose members are predominantly expressed in the central nervous system and have been implicated in cell-cell adhesion, axon guidance and dendrite self-avoidance. Heterozygous loss-of-function mutations in humans result in the childhood epilepsy disorder PCDH19 Girls Clustering Epilepsy (PCDH19 GCE) indica...

This paper introduces the concept of Ontology based Geo-Object Catalog (OGOC). An OGOC acts as a focal point for a federation of independent geoobject sources, providing consolidation services for the geo-objects represented in several, as well as access services to query geo-objects and metadata. To accomplish this task, an OGOC stores a reference ontology, which also includes reference geo-ob...

Due to popular use of internet and fast progress of communications technology, the researches related to GIS in environmental models is being focused to use Geospatial Information System (GIS) in a Service Oriented Architecture (SOA). In this architecture, the geo service requesters can access the provided geo-services through the communication network by using client/server method. Effectivene...
