This paper describes a linked-data platform to publish sensor data and link them to existing resource on the semantic Web. The linked sensor data platform, called Sense2Web supports flexible and interoperable descriptions and provide association of different sensor data ontologies to resources described on the semantic Web and the Web of data. The current advancements in (wireless) sensor netwo...
The paper presents a visualization-based approach to explore large databases of geographic metadata. The aim of the data exploration is to search and acquire expressive geographic data to create a geographic information system. Metadata repositories which provide information about available geographic data exist on the web and are usually queried to perform data acquisition task. We propose a v...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
Geography learning materials are very complex and need to take advantage of many resources tools. Technology is needed develop the skills creativity students. The use webGIS media can encourage students learn by conducting simulating geographical studies professionally through collaborative work with material applied so that they do not only memorize places. purpose this study was determine eff...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
New interactive web services are dramatically altering the way in which ordinary citizens can create digital spatial data and maps, individually and collectively, to produce new forms of digital spatial data that some term ‘volunteered geographic information’ (VGI). This article examines the early literature on this phenomenon, illustrating its shared propositions that these new technologies ar...
We present in this paper our experience in the development of a geographic information system that includes a large database (over seven GB) with information about infrastructure and facilities of the municipalities in the province of A Coruña (northwestern Spain). Three interesting aspects of the whole project are described in some detail due to its intrinsic interest for the development of th...
Spatial Information Search Engine (SISE), aiming to search the World Wide Web for online geographic information to meet the end users needs, is a totally new research area in the field of spatial information sharing. In this paper we introduce an OpenGIS WMS specification based SISE prototype system. This SISE prototype is capable of discovering available WMS Servers dynamically, choosing quali...
