The Commission on Geoinformation Infrastructures and Standards of the International Cartographic Association (ICA) is working on defining models of spatial data infrastructures (SDIs). SDI models from the enterprise and information viewpoints of the Reference Model for Open Distributed Processing (RM-ODP) have already been presented. Our model from the computational viewpoint identifies the main computational objects of an SDI and their interfaces, which are modelled using Unified Modelling Language (UML) component diagrams. Presented here is the first comprehensive SDI model from the computational viewpoint, which enhances the understanding of the computational objects and their interactions in an SDI. This viewpoint complements the previous two and together, the three viewpoints contribute towards a more holistic interpretation of an SDI, which is independent of specific SDI legislation, technology and implementations. For the computational viewpoint, we identified six computational objects, SDI Registry, SDI Data, SDI Processing, SDI Application, SDI Portrayal and SDI Management, and their provided and required interfaces. We describe the interactions of the computational objects in stakeholder activities and the roles they play in the different processes of SDI development and use, which we identified as Initiation, Creation, Management, Manipulation, Access, Processing, Evaluation and Liaison. Two tables summarise the SDI services that are provided by computational objects for stakeholder activities and SDI processes. © 2013 Copyright Taylor and Francis Group, LLC.

The Inden opencast lignite mine is located some 20 km to the north-east of Aachen in Germany's Rhineland. After the end of lignite mining around the year 2030, a lake measuring some 11.8 km2 is planned to be created. It will mainly be filled with water from the river Rur flowing past in the immediate vicinity of the opencast mine. Filling the lake volume of some 800 million m3 will take 20 to 25 years. During the past ten years, the basic water management questions arising in connection with the creation of the Inden mine's residual lake were settled within the scope of the state-planning approval procedure. It could be demonstrated by means of a numeric river catchment model that the envisaged withdrawal of water from the Rur is feasible and compatible with the water body's ecological and hydromorphological targets as well as its industrial use.

Professional understanding of official geodetic spatial reference in Germany has evolved consistently with the AdVproject «Repeated measurements in the German main height network (DHHN)». Nowadays this is called the «integrated geodetic spatial reference» as holistic conception of its geometrically and physically defined components. In thispaper, the results of DHHN2016 are compared from the geodetic point of view with geological findings in the area of Eifel. As a result, the scientific potential of the DHHN results increases significantly through an interdisciplinary approach (here: Geodesy-Geology). The uplift of the Eifel region is geologically well studied. The determined uplift rates for the last 800.000 years range from 0,06 to 0,38 mm/a. Accurate geodetic measurements in the study area for the period from 1960 to 1980 determined uplift rates in the Eifel of 0,6 to 1,2 mm/a (Mälzer et al. 1983). In this study, quite identical movement patterns and uplift rates between 0,75 and 1,25 mm/a for the time period from 1983 to 2007 were observed. Therefore the geodetic uplift rates of the Eifel region are several times higher than estimated by geological records. They are comparable to the recent uplift rates of the Alps. Potentially elastic deflection of the lithosphere may be a cause for the uplift of the upland regions north of the Alps. The effect of elastic deflection was so far only applied on rift basins. The results imply an accelerated uplift of the Eifel region and also a strong, faultbound activity at the western margin of the Lower Rhine Embayment. The recent crustal movements measured during the geodetic DHHN campaign are significant. Therefore new geologic models of the recent crustal deformation are needed - models, that also take into consideration the elastic parameters of the crust.

This article describes the use of one way precise levelling in areas of ground movements in North-Rhine Westphalia, Germany. It takes into account the measurement of the German first order levelling network between 2006 and 2011. About one third of the area in North-Rhine Westphalia is affected by mining and tectonic activities resulting in partly massive changes of the surface elevation and position. Classical precise levelling campaigns, which guarantee the necessary accuracy, are not possible in these areas. In addition declining personal and financial resources of all participating parties do affect the levelling projects. For the first time one way precise levelling was tested in 2009 to partly substitute the classical two way levelling method. The occurring loss of accuracy should be restricted by the configuration of the levelling network and the use of digital instruments. First experiences and results of the levelling campaign 2009 in the open mining region Rheinbraun will be presented. Aspects will be the quality management, the economic viability and organisational issues.

In 2014 the surveying and mapping administration of North Rhine-Westphalia (Geobasis NRW, located at the Cologne Government Regional Office) provided, for the first time, a statewide national 3D-building model in the level of detail 2 (LoD2: integrated standardized roof forms). It consists of 10 million buildings. The whole derivation process was fully automatized using available reference data of the cadastre and airborne laser scan measurements. After this first derivation of the 3D-building model, additional tasks are necessary to handle existing errors. Buildings are interactively corrected by the use of oriented aerial pictures. These changes are stored in the data base of the 3D-building model.

The INSPIRE directive especially supports the objectives of the European environmental policy. In North Rhine-Westphalia INSPIRE is additionally recognised as an opportunity to accelerate the efforts of building up regional, national and European spatial data infrastructures. INSPIRE is a European directive focusing the holistic provision of spatial information in various fields, which is not only a matter of the surveying, mapping and the cadastre administration. The demand for official spatial information increases both inside and outside of the public administration and cross-border. Official spatial information has to be provided comprehensively, homogeneously and interoperably. Beside a pure data oriented view also technical, organisational and legal-administrative requirements have to be taken into account in a user-oriented way. Success and acceptance of INSPIRE therefore depend on an extensive organisation and coordination of the spatial data infrastructure.


Spatial data for topography and for touristic facilities can only deploy practical value if they are currently available for users in a suitable form. In North Rhine-Westphalia this task of the national survey is run by the Cologne district government. In order to ensure timeliness and completeness the responsible department researches the changes itself or it receives them in cooperation with other services in charge. To update the database for topography and touristic facilities a common processing system is being installed. It includes different services working together simultaneously on the update-process. Thus, the benefit of synergies will be used.


The more concrete aims of land consolidation procedures with private benefit, based on the German Land Consolidation Act, shall be adapted to the changes in rural areas. It is not only the structural change in agriculture but also the demands on an adequate and demand-oriented system of agricultural roads that do effect the proceedings and plannings in land consolidation procedures. With the land consolidation procedure in case of permissible compulsory purchase, based on chapter 87 ff. LCA, infrastructure projects shall be realized which avoid interventions in ownership and agricultural structures. These original objectives may be achieved in combination with further positive effects.
