Abstract An essential support for environmental monitoring activities is a rigorous definition of a homogeneous cartographic system, required to correctly georeference and analyse the acquired data. Furthermore, since 2007, the European Infrastructure for Spatial Information in the European Community (INSPIRE) Directive affirms the necessity to harmonise the European maps for permitting cross-border analysis. For satisfying these requirements, the authors have developed a procedure for the cartographic harmonisation in the crossborder area studied during the European project Alpes Latines-Coopération Transfrontalière (ALCOTRA)–Alpes Latines-Individuation Resources Hydriques Souterraines (ALIRHyS). It concerns the hydrogeological study of various springs and other water resources in an area between Italy and France including their constitution in a cross-border system. The basic cartographic information is obtained from existing national maps (Italian and French data), which use different coordinate systems or projection methods and are produced from different data acquisitions and processes. In this paper, the authors describe the methods used to obtain wellharmonised middle-scale maps (aerial orthophotos, digital terrain model and digital maps). The processing has been performed using geographic information system (GIS) solutions or image analysis software in order to obtain useful and correct cartographic support for the monitoring data, even if the obtained maps could be further analysed or refined in future works.

Introduction A basic issue for the European cartography, since the publication of the European Infrastructure for Spatial InfoRmation in the European Community (INSPIRE) Directive, is the harmonisation of national maps of European States to perform correct cross-border environmental analysis (INSPIRE Directive 2007). The necessity of procedures for cartographic harmonisation has produced numerous researches (Jaroszewicz et al. 2013). Various studies analyse the harmonisation of reference systems (e.g. HELIDEM project) or the maps themselves (Dabove et al. 2013b) for general purpose product, some other ones describe the harmonisation of the mapping applications on specific thematic data, for example for environmental studies (Fabbro and Haselsberger 2009). Furthermore, some studies for the harmonisation of semantic data based on INSPIRE have been performed, but often they concern specific themes: e.g. land cover/land use (Valcarcel et
