About the platform

Què és l'IDEAMB?
An SDI platform (spatial data infrastructure, IDE in Catalan) is a computer system integrated by a set of resources (catalogs, servers, software, data, etc.) focused on geographic information management, which are accessible via the Internet and comply with a set of interoperability conditions (standards, specifications, protocols, etc.) and that allow users to use and combine them according to their needs, simply using a web browser.

In this way, an SDI can be described as a set of computer components that interact to facilitate cataloging and subsequent access to the different geographic information resources (data sets and Web services) that an organization generates. This cataloging is materialized by a set of attributes of the resource that describe it and are known as "metadata".

IDEAMB is, consequently, the metropolitan infrastructure that facilitates the management and exploitation of the geographic information resources produced by the AMB.

What components form an SDI?
The IDEAMB platform integrates the following components:
  • Geographical data: data referring to a location on the land (georeferenced) and that represent objects from the real world (rivers, roads, land uses, contour lines, etc.).
  • Services: functionalities associated to the layers of information offered through the web, based on open and interoperable standards in order to facilitate user access to all published data. Among the most important services offered by an IDE we can find discovery, visualization, download or transformation services, collected by the European INSPIRE directive, based in many cases on standards published by the Open Geospatial Consortium (OGC).
  • Metadata: they inform users on the descriptive characteristics (content, quality, contact, etc.) of geographic resources, either data sets or geographic services. In the case of data sets, the metadata collected is specified by the ISO 19115 standard and, more specifically, the is stipulated in the AMB profile of the mentioned standard. In the case of web services, the AMB profile is derived from the 19119 standard..
  • Technology: refers to the computer architecture that supports the client-server interaction, through which the server processes requests of several clients and delivers the appropriated responses. In the case of IDEAMB, requests are made through user interfaces such as the catalog, which allows searches of geographic resources, and a set of tools that allow them to be viewed (the IDEAMB viewer, the cartography geoportal and the geoportal of the consolidated urban planning).
  • Rules and standards: they are voluntary application documents that regulate and guarantee the interoperability of the geographic information, so that data and web services can be located, interpreted and transferred through the web. The standards followed in IDEAMB have been previously specified.
  • Political agreements: they allow to establish coordinated actions between institutions, through a legal framework with legal and technical effects that support the implementation of the IDE at all levels of the organization.
  • Actors: users that have a role within the IDE, among which there are data producers, intermediaries and users.

Why is it necessary?
"It is the infrastructure that facilitates the management and exploitation of the geographic information resources produced by the AMB. The objective is to facilitate the dissemination of the geographic information resources generated by the metropolitan administration, and its creation is linked to the regulatory context defined by the European Parliament Directive INSPIRE 2007/2/CE (Infrastructure for Spatial Information in Europe).

INSPIRE defines a set of general rules for the establishment of a spatial data infrastructure (IDE) within the European Union (EU), based on the infrastructures of the different state members. The implementation of INSPIRE implies the compatibility and homogenization of geographical information that can be used and exchanged within the framework of the European Union. The exchange is based on five fundamental principles among which, for the purposes of this document, we would like to point out that "the information must be easy to locate and must specify the conditions of acquisition and use, as well as to offer detail enough so that the user can determine if it fits to the purposes".

This directive is mandatory by any government or public administration of a local, regional or national level that produces geographic information in electronic format and that is related to some of the 34 issues of the directive and that is within its competence.

The transposition of the INSPIRE directive into the Spanish legal framework (LISIGE), as well as other regulations and initiatives at the regional level, have defined the architectural and content framework of the IDEAMB.
