OPeNDAP

New Web-GIS Architecture

As the fast growth of Web-GIS produces more and more applications requiring data stored at remote databases, data access security and data transfer speed over the internet are at issue. The authors compare traditional client/server approaches with the open-source OPeNDAP data server.<P> Traditional client/server Web-GIS applications are usually based on accessing databases stored in one server machine or within a network of servers. Data transport goes as follows: -client requests data using web interface, web service or other interface -data requests sent to HTTP server, which sends pre-defined SQL statement to database -database retrieves data and sends resulting dataset back...

IDENA: Spatial Data Infrastructure of Navarre

Architecture, Metadata and Interoperability

Several years ago Navarre (Spain) implemented a Land Information System (SITNA) within its corporate Information System. Notwithstanding the success of this initiative there remains a lack of metadata, an issue highlighted over the past two years by INSPIRE (Infrastructure for Spatial InfoRmation in Europe). This is the context for IDENA (Spatial Data Infrastructure of Navarre), developed by Trabajos Catastrales S.A., to give SITNA a catalogue of meta-information, distribution of metadata and interoperability with other SDIs. The 2004 Commission of the European Community publication “Proposal for a Directive of the European parliament and of the council establishing an infrastructure for spatial... (read more)

How Historians Are Now Using Computer Technology

Investigating Spatial Effects in Architecture and Painting

Historians increasingly use the computer for analysing spatial effects and perspective spaces in ways that were hitherto impossible. The authors provide examples of their extensive work on computer modelling of Roman and Renaissance architecture and painting. The computer facilitates the analysis of ‘fictive’ spaces such as painted scenes, and the modelling of ‘anamorphism’, one of the most striking forms of perspective effect (distortion) employed in Renaissance art. Perspective scenes such as those by the Renaissance architect Sebastiano Serlio rely, for example, on vanishing points in mid-air which are impossible to model in conventional ways, and theatrical scenes such as Serlio’s...
