The use of 3D technologies in archaeology and architectural history has grown enormously. Nowadays, 3D technologies are used to record, present, analyse and reconstruct archaeological sites. Since the used tools mostly originate from other domains, the developments are characterised as technology-driven rather than methodology-driven. The recent trend of Free and Open Source Software (FOSS) and...

This paper presents an approach for rapid assessment of sustainability for Mainland China based on a multilayer index system. Efficient assessment is conducted with the basic mapping units at county and city levels. After evaluating a comprehensive sustainable development index, SDI, for each unit, five rankings of sustainability are determined, and a zonation map produced. Regional characteris...

The lack of reliable data for ground solar irradiance (direct normal and global irradiance) is a major obstacle for the development of adequate policies to promote and take advantage of existing solar technologies. Although the radiation that reaches the outer layers of the atmosphere is well defined and can be easily calculated, the solar irradiance that reaches the ground level where solar co...

1 Department of Computer Science and Engineering, 382 Fitzpatrick Hall, University of Notre Dame, Notre Dame, Indiana 46556, [email protected] Abstract  Safety-critical software is a core topic in courses on “ethics and computing” or “computers and society,” as well as in software engineering courses. The Reagan-era Strategic Defense Initiative (SDI) was the focus of a great deal of technical arg...

Today, the existence of metadata is one of the most important keys for an effective discovery of geospatial data published in Spatial Data Infrastructures (SDI). However, due to lack of efficient mechanisms, integrated in user daily workflow, to assist users in generating metadata, little metadata is produced. This paper presents a mechanism for generating and publishing metadata with a Publica...

خشکسالی از جمله بلاهای طبیعی است که رخداد آن اثرات بسیار زیانباری بر اکوسیستم های مختلف وارد می سازد. خشکسالی هیدرولوژیکی که به مفهوم کمبود جریان آب نسبت به مقدار نرمال آن تعریف می شود. از رویدادهای طبیعی و تکرارپذیر در هر اقلیمی است. بررسی علمی این بلای طبیعی یکی از نیازهای اساسی برنامه ریزی های کشاورزی و منابع آب در اقلیم های خشک محسوب می شود. پیش بینی خشکسالی به عنوان مهمترین راهکار در مقابل...

A huge amount of geographical datasets are becoming available in distributed environments like Spatial Data Infrastructures (SDI). These datasets are very heterogeneous since they come from different independent sources and surveys and are structured in different formats. In the context of a national SDI that needs to assure an adequate quality level of the data it provides, it is necessary to ...

Objectives. Assessment of left ventricular (LV) systolic function in patients with atrial fibrillation can be difficult. Acoustic cardiography provides several parameters for quantifying LV systolic function. We evaluated the ability of acoustic cardiography to detect LV systolic dysfunction in patients with and without atrial fibrillation. Design. We studied 194 patients who underwent acoustic...

GeoWeb2.0 is the geographic embodiment of O’Reilly’s ideas and it is increasingly becoming a trend method to construct a GIS application. Spatial Data Infrastructure (SDI) is really GeoWeb applications. In the quest to establish the GeoWeb2.0, a free version of rich spatial Flex Viewer has been released by Environmental Systems Research Institute, Inc (ESRI). While the remote sensing satellite ...

Awareness of the importance of spatial data in achieving development strategies is high in Rwanda. Government and non-governmental institutions are aspiring to use Geographic Information Technologies (GITs) in their day-to-day activities. The non-existence of a National Spatial Data Infrastructure (NSDI) in Rwanda brings to light serious issues for consideration. Still lacking is a spatial data...
