The article is devoted to solving the scientific problem of spatial data storage management using geoportal systems on basis analyzing patterns spatiotemporal organization complex dynamic hierarchically organized metageosystems. paper proves that integrating large arrays information in infrastructures (SDIs) can be solved by designing multi-model storages operating database different classes. T...

The field of Spatial Data Infrastructure (SDI) is developing and approaches rapidly a “critical mass” of more or less operational SDIs. The purpose of the paper is to anticipate the possible impact of the maturing SDI field on its research agenda. Initial initiatives were predominantly techno centred whereas present initiatives are generally placed within current practices and developments in t...

It is often mentioned that organisational aspects should be incorporated in SDI assessments, yet an assessment instrument is still lacking. In this chapter an approach for assessing organisational aspects of a Spatial Data Infrastructure (SDI) will be developed and used on literature covering management aspects of Geographical Information Systems (GIS) and SDIs. Organisational aspects will be a...

The ability to share and combine geographic data from different information sources in a consistent way is a key issue for enabling successful implementation of Spatial Data Infrastructures (SDIs). This can only be done through a deep understanding of databases structure and content. In this poster, we propose to do that through the elicitation and formalisation of geographic database specifica...

Topographic data sets produced by the National Mapping Agencies (NMAs) are an essential part of Spatial Data Infrastructures (SDIs). Both global and European developments will denote that the NMAs will have to adopt new strategies for managing topographic data. This paper will embrace some of the requirements and introduce a framework for topographic data management based on the analysis of stu...

The role of the GSDI Association, in essence, is to facilitate better global outcomes through utilisation of geographic information and spatial data infrastructures (SDIs). This role directly complements the proposal to establish a United Nations Committee on Global Geographic Information Management (UNCGGIM). The GSDI Association's view of the changes now taking place in the geographic informa...

The issue of water conservation and economy in its use agricultural production is one the most important issues sustainability at present time especially with crops that need to consume large quantities water, such as corn.The impact subsurface drip irrigation system (SDIS) on corn cultivars SYN-6 R-106 was observed based some technical indicators, under three distances (DID) 22,24 26cm. experi...

Data Trusts are an important emerging approach to enabling the much wider sharing of data from many different sources and for purposes, backed by confidence clear unambiguous governance. combine technical infrastructure with governance framework a legal trust. The concept Trust applied specifically spatial offers significant opportunities new future applications, addressing some longstanding ba...

HIV+ individuals with and without substance use disorders make significantly poorer decisions when information about the probability and magnitude of wins and losses is not available. We administered the Game of Dice Task, a measure of decision making under risk that provides this information explicitly, to 92 HIV+ and 134 HIV- substance-dependent men and women. HIV+ participants made significa...

Emerging standards from ISO/TC 211 convey principles for building interoperable, distributed geographical information systems. Important building blocks are UML for specifying the conceptual schema and XML for implementation-neutral exchange of geodata models. By means of a model-based approach using UML, and corresponding mapping to XML and service implementations, it is possible to provide a ...
