Abstract
Seamless Geospatial Reference Data for Cross Border Spatial Data Infrastructures

Today cross border projects are common. But not only national cross border projects we are also thinking in regional cross border projects. Geo-Data are seamless. There are the same landscape and data at both sides of borders line. To manage a cross border project we need the same data at both sides (nations or regions). Many cross border projects are not possible due there are not the same data (data type or data updating) in both sides, or data processing in order to set a unique dataset crossing borders is too expensive or need too much time. The easier and less expensive way to manage data for cross border projects are data and services interoperability, based on standards and common specifications, and harmonization. Interoperability is provided by Inspire Implementing Rules setting up the project in a SDI environment based on Inspire-OGC web services and interoperability of spatial data sets and services according the Commission Regulation (eu) n? 1089/2010 of 23 November 2010.

But infrastructure crossing borders is mainly data and we need to have at least a continuous back bone data all over the project crossing border zone. This is the reason why Inspire Directive is setting in a short time level of availability the Annex I group of information. This is the group of Geo-Spatial Reference Data: Coordinate Reference Systems, Geographical grid systems, Geographic Names, Administrative Units, Addresses, Cadastral Parcels, Transport Network, Hydrography, Protected Sites. But also are part of the Geo-Spatial Reference Data: Digital Elevation Models, Land Cover (and jointly Land use), Orthoimages, Geology, all of them are themes in the Annex II.

Geo-Spatial Reference Data provides an unambiguous data location for thematic databases. It provides the geospatial data framework to spatially understand the spatial information managed. It must be authoritative guaranteed information. The best practice on Geo-Spatial Reference Data crossing regional borders in Spain is sets up as an example.
br> EU and National Geo-Spatial Reference Data policy need to take into account these data gathering but in order to get common authoritative guaranteed information for any kind of project at local, regional, national or European dimension data a bottom-up approach is needed.

The words to be considered are interoperability but also harmonization.
