Abstract
This paper presents the results of the research project that presents the main guidelines must be taken into account to build SDI scale city-region in Colombia, based on the concepts of city and region applying in the country framed on the produced spatial data and geospatial standards required for the construction of SDI initiatives. The research used methodology was developed from a series of steps described below: Stage 1 "Documentation Review" investigation about the main concepts of spatial data infrastructures and their hierarchy also were considered. Exploration about the worldwide IDE initiatives, differences with Geo-graphic Information System (GIS) and revision in the definition and full of meaning of City-Region concept. Stage 2 "Development Survey": a tool to identify the situation of geo-graphic information about geographic data produced by The District of Bogotá and national institutions, spatial data producers, geospatial standards implementation, and access and sharing of spatial infor-mation; subsequently, this data was tabulated and analyzed the results. Stage 3 "Geospatial Standards": In order to guarantee the interoperabil-ity of data, geographic standards should be implement at the proposed City-Region SDI. Stage 4 "Proposed Methodology" Is relate to definition of main compo-nents of a City-Region SDI, establishing how to consolidate each com-ponent, and it is in this stage where a new component is proposed for the City-Region SDI. The research allowed a state of the current situation regarding the production of geographic data, geospatial standards implementation, accessibility and use of information technology application related to the geo web services, and thus shows a very real evidence of the problems in terms of Geographic Information Management, which lead to the design this methodology that helps to create and implement spatial data infrastructure to scale City-Region in Colombia, and is the initiative to integrate geospatial information issues and City Region.
