[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 paper describes the set up and the progress of the EuroSDR project that studies the state-of-the-art in automated map generalisation implemented in commercial out-of-the-box software. The project started in October 2006 with a project team consisting of National Mapping Agencies (NMAs) and research institutes. From October 2006 till May 2007 four test cases of four different NMAs were selected, consisting of a large scale source data set, requirements for the smaller scale output map as well as symbolisation information. Much effort has been put in specifying and harmonising requirements for the output maps. These requirements have been defined as a set of constraints to be respected in the output maps. From June 2007 the project team tested the four test cases with four commercial out-of-the-box software systems: ArcGIS, Genesys, Change/Push/Typify and Clarity. The vendors of these systems performed parallel tests on the four test cases in which they were allowed to customise their systems. An evaluation methodology has been designed and partly implemented. Results are expected by the end of 2008.
