Infrastructure for Spatial Information in the European Community
The Infrastructure for Spatial Information in the European Community (INSPIRE ) is an initiative of the European Commission with the aim to create a European Spatial Data base with integrated spatial information services. Directive 2007/2/EC of 14 March 2007 of the European Parliament and of the Council of 14 March 2007 establishing an Infrastructure for Spatial Information in the European Community (INSPIRE ), in force since 15 May 2007, requires Member States to gradually interoperable basic geodata ( initially coordinate reference systems, Geographical grid systems, Geographical names, administrative units, addresses, parcels, transport and water networks) and geodata (initially on protected areas and geology) provide. The obligation to make data available, only applies to existing and present spatial information in digital form; the Directive does not require the reacquisition of previously non- existing digital geospatial data.
OBJECTS AND ADVANTAGES
The public institutions start due to the entry into force of INSPIRE Directive, their spatial data prepare INSPIRE compatible with the timetable initially provides for the generation of uniform metadata. Spatial data can thus be used beyond the respective administrative and national boundaries. In German-speaking countries, this structure runs under the slogan spatial data infrastructure (SDI ). Spatial data in the form of maps, aerial photographs and metadata ( information about, for example, origin and time of the survey ) are employed in the form of standards-compliant (usually based on the standards of the OGC) services and taking into account definitely agreed upon application profiles, such as the WMS - DE- profile 1.0 or AdV - profile for WMS offered.
INSPIRE directs the Infrastructure for Spatial Information in Europe, by certain specifications to be made here, to be met by services. A European, uniformly designed spatial data infrastructure barriers can be broken down by all available data will be processed accordingly and provided via portals that are tailored to the citizens of a particular European country and call further information and contact person. This ensures the long term that, for example, North Rhine-Westphalian service in Portugal or Bulgaria if required can be used. The strict alignment of certain technical specifications, for example, direct comparisons between different European countries are only possible for non-technical users. A major difficulty lies so far is that each European country has different and often multiple projection systems for the representation used, which are often uncommon abroad and thus digitally can not be presented in a cartographically correct figure. Even within Germany there are already problems, there must be resorted to different meridian systems, if a representation with a large east- west extension is to take place. With Europe unified projection systems, such as the ETRS89, which can be used for the European Area, Member countries should be prompted increasingly to dispense with regional projection systems in favor of a European solution. Of particular importance are the future not only pure image data (maps and aerial photographs), but also alphanumeric information, the " clicking " on the map display can be accessed via. General statistical data such as population growth in cities or regions will therefore be available for everyone. Another advantage of uniform spatial data is that the citizen is a very powerful instrument is given to the hand by publishing them to observe spatial processes (eg, planning, such as construction of large facilities, roads, industrial areas) and to take direct comments to can. Great importance is also obtain environmental monitoring in this regard.
