In the last years, there has been a huge increment in the number of e-government services offered to the citizens and companies. However, environment-related permits are among the least developed kind of e-government services in Europe. Environmental management and government requires the use of geographic information and spatial data infrastructures (SDIs) are being providing the framework for...

The spatial data infrastructures (SDIs) which constitute a direct link between users and the large Earth observation industry, have leading role in establishing market opportunities space sector. information supplied through various forms of SDI platforms exhibits increases demand volatility. users' is unpredictable vulnerable to high evolution shifts. We study effect extreme demands for partic...

Spatial data infrastructures (SDIs) and data mining have been a key challenge of a modern society. SDIs as well as spatial data mining should become a topic of the annual conference EnviroInfo. The main objectives of our paper are: (1) To provide a short overview about spatial data infrastructures (definitions, goals, hierarchy of SDIs, and relations to other initiatives). (2) To describe the t...

Technological development and increasing awareness of geodata and its use has caused an explosion of digital content. However, this was not accompanied by dissemination and accessibility measures. Spatial Data Infrastructures (SDIs), allowing extensive reuse of geoinformation, may offer a solution. SDIs face organisational, technological, legal, cultural and linguistic challenges. The enrichmen...

The spatial information vision for most countries is to create a virtual state where any spatial information is available to any user, any time and any place. This is a simplistic vision that presents many challenges, with the major challenge being the creation of a spatial data infrastructure (SDI) to support the vision. Importantly unless we can agree on a spatial information vision for each ...

Spectral measurements are employed in many precision agriculture applications, due to their ability to monitor the vegetation's health state. Spectral vegetation indices are one of the main techniques currently used in remote sensing activities, since they are related to biophysical and biochemical crop variables. Moreover, they have been evaluated in some studies as potentially beneficial for ...

A Spatial Data Infrastructure (SDI) facilitates and coordinates the exchange and sharing of spatial data between stakeholders in the spatial data community. With this objective in mind, countries throughout the world are developing SDIs to manage and utilise their spatial data assets more effectively. These countries are developing SDIs to assist in various kinds of decision-making at different...

The basis of this study, which was put forth in order to appropriate a special area the hyperring theory, has recently been studied as generalization ring uses module theory an application field, is based on integrally closed Krasner hyperrings and (almost) integral dependence applications krasner hyperrings.

BACKGROUND Edentulism is an important issue and will remain so due to high numbers of edentate individuals worldwide. For many years, complete dentures have been the only treatment option for this population. Implant overdentures have been shown to have many advantages over conventional complete dentures. However, although dissatisfied with their mandibular dentures, some edentate elders are re...

Spatial data is a key resource for national development. There is a lot of potential locked in spatial data and this potential may be realized by making spatial data readily available for various applications. SDI (Spatial Data Infrastructures) provides a platform for the data users, producers and so on to generate and share spatial data effectively. Though efforts to develop spatial data infra...
