[Vedettes matières IGN] GénéralisationRésumé : (auteur) National Mapping Agencies (NMAs) are still among the main end users of research into automated generalisation, which is transferred into their production lines via various means. This chapter includes contributions from seven NMAs, illustrating how automated generalisation is used in practice within their partly or fully automated databases and maps production lines, what results are currently being obtained and what further developments are on-going or planned. A contribution by the European Joint Research Center reports on the use of multiple representation and generalisation in the context of the implementation of the European INSPIRE directive. The chapter finishes with a synthesis of recent achievements, as well as future challenges that NMAs have begun to tackle.

[Termes IGN] spécification de contenuMots-clés libres : generalization Résumé : (auteur) In traditional generalisation flow lines, the target map is specified upstream, manually, by cartographers and is intended to answer generic, well-identified user needs. In the emerging context of on-demand mapping, maps have to be derived automatically for users whose requirements are not known in advance, and who may need to integrate their own data. The definition of suitable target map specifications thus becomes part of the service, which raises challenges that are explored in this chapter. The first challenge is to set up a formal map specifications model, rich enough to guide the whole map derivation process. The second challenge is to collect requirements and to assist the user, who is not supposed to be a map designer, in the specification of a map usable for their task and one that respects cartographic standards.

[Vedettes matières IGN] GénéralisationRésumé : (auteur) [introduction] This paper presents the results of the EuroSDR (European Spatial Data Research) research project that studied the state-of-the-art of automated generalisation in commercial software in a collaboration between National Mapping Agencies (NMAs), research institutes and vendors. The aims of the study were to learn more about generic and specific map requirements of NMAs, to show possibilities and limitations of commercial generalisation software, and to identify areas for further developments based on latest research advances. The project consisted of three main steps: requirements analysis, testing, and evaluation. The requirement analysis (carried out from Oct 2006 till June 2007) resulted in four representative test cases, formalised and harmonised NMA map specifications for automated generalisation as well as an analysis of the defined specifications that shows the similarities and differences between map specifications of different NMAs. The four NMAs who provided the test data are: Ordnance Survey Great Britain (OSGB), Institut Géographique National, France (IGNf), The Netherlands’ Kadaster (Kadaster) and Institut Cartogràfic de Catalunya (ICC). The testing was performed from June 2007 to Spring 2008 by project team members (from NMAs and research institutes) on out-of-the-box versions of four generalisation systems: ArcGIS (ESRI), Change/Push/Typify (University of Hanover), Radius Clarity (1Spatial) and axpand (Axes Systems). At the same time the vendors (except Axes systems) carried out tests with the same test cases with possibly improved and/or customised versions of their systems. The tests resulted in 35 outputs consisting of 700 thematic layers, where it should be noted that the effort to execute one test was approximately 1 week. Several example outputs with an extract of the same test case are shown in Figure 1. The evaluation, carried out from summer 2008 to spring 2009, consisted of an evaluation of meta aspects (based on information recorded by the testers) and of an evaluation of the generalised outputs themselves. The latter evaluation consisted of three parts that complemented each other: a) automated constraint-based evaluation, b) evaluation which visually compared different outputs for one test case and c) a qualitative evaluation of outputs by cartographic experts.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) : This report presents the EuroSDR research project that studied the state-of-the-art of automated generalisation in commercial software in a collaboration between National Mapping Agencies (NMAs), research institutes and vendors. The aims of the study were to learn more about generic and specific map requirements of NMAs, to show possibilities and limitations of commercial generalisation software, and to identify areas for further developments based on latest research advances. The project consisted of three main steps: requirements analysis, testing, and evaluation. The requirement analysis (carried out between Oct 2006 till June 2007) resulted in four representative test cases, formalised and harmonised NMA map specifications for automated generalisation as well as an analysis of the defined specifications that shows the similarities and differences between map specifications of different NMAs. Between June 2007 and Spring 2008 tests were performed by project team members (from NMAs and research institutes) on out-of-the-box versions of four generalisation systems: ArcGIS (ESRI), Change/Push/Typify (University of Hanover), Radius Clarity (1Spatial) and axpand (Axes Systems).At the same time the vendors (except Axes systems) carried out tests with the same test cases with improved and/or customised versions of their systems. The tests resulted in 35 outputs consisting of 700 thematic layers, where it should be noted that the effort for one test was approximately 1 week. The evaluation, carried out between summer 2008 and spring 2009, consisted of an evaluation of meta aspects (based on information recorded by the testers) and of an evaluation of the generalised datasets
themselves. The latter evaluation consisted of three parts that completed each other: a) automated constraint-based evaluation, b) evaluation which visually compared different outputs for one test case and c) a qualitative evaluation by cartographic experts. From the project results it can be concluded that all systems offer potentials for automated generalisation. However the results highlighted a few issues that identify areas for further development in both research and commercial systems. Although the results show that for many problems solutions do exist (e.g. building simplification), the algorithms are difficult to parameterise and a direct match between parameters and specifications was often missing. In addition none of the four test cases were fully solved by the out-of-the-box systems. While some problems are close to being solved (generalisation of individual buildings and roads), a few problems are far from being solved. Firstly it is impossible with the tested systems to apply different algorithms and/or parameter values in different contexts. This is either not supported or a measure to detect the appropriate contexts is missing. Another remaining generalisation software problem is operations that concern more than one object (e.g. network typification). Also, the generalisation of the topographic context in an integrated manner with the terrain is not appropriately covered in the tested systems. It should be noted that some of the missing functionalities were fixed in the vendors’ parallel tests (e.g. buildings elimination and displacement algorithms in ArcGIS and Radius Clarity). Although these results may seem disappointing, some final thoughts may help to put the results in the right context. Firstly the project had very high ambitions (i.e. many specifications were defined; the selection of test cases focused on known and complex problems; the ultimate aim of the generalisation process was high quality paper maps). Secondly, the project is well received by vendors to push internal developments. In addition it is not a surprise that out-of-the box versions are not capable of fulfilling NMA requirements, which is also shown by the fact that customised systems are used more satisfactory in practice. Consequently customisation of the systems should be further developed and should be one of the focuses in a future project.Note de contenu : 1. PRESENTATION OF THE PROJECT

The objectives of this study are to learn more about generic and specific requirements for automated map generalization, to show possibilities and limitations of commercial generalization software, and to identify areas for further research. The methodology had to consider all types of heterogeneity to guarantee independent testing and evaluation of available generalization solutions. The paper presents the two main steps of the methodology. The first step is the analysis of map requirements for automated generalization, which consisted of sourcing representative test cases, defining map specifications in generalization constraints, harmonizing constraints across the test cases, and analyzing the types of constraints that were defined. The second step of the methodology is the evaluation of generalized outputs. In this step, three evaluation methods were integrated to balance between human and machine evaluation and to expose possible inconsistencies. In the discussion the applied methodology is evaluated and areas for further research are identified.
