[Mapping of parasitological environmental data: the tick Ixodes ricinus--a case of study].

While the mapping of health data is not new for epidemiologists the incorporation of differentiated environmental factors, e.g., temperature, rainfall, humidity, elevation, vegetation type, host abundance and distribution, zoonotic reservoirs of infection can create a new opportunities for parasitologists. Suitable tools for spatial modeling of health problems and pathogen occurrence in space and time are provided by geographic information system (GIS). It is computer-based system which integrates, storages, edits, analyses, shares and displays information. This software system is based on connection between information--data and their location. GIS applications allow users to create interactive queries, analyze spatial information, edit data and maps. GIS is very useful to define the habitats of parasites, especially for the ticks which are strong depended on environmental conditions. Mapping not only enables to create maps based on field monitoring but also to create forecasting maps for prevention and control strategies on small and large scale. Up to now ticks and tick-borne diseases (TBD) having strong relationship with the ecosystem are highly amenable to predictive mapping. The aim of study is the characterization of procedural steps with regard to entering field environmental data to GIS database and their visualization on digital maps. The field date of tick monitoring conducted in April 2008 in the Wrocław area (the Osobowicki Forest) made possible to create digital database. ArcView as one of three separate software products of ArcGIS (a scalable framework for implementing GIS) was used to create an interactive maps. Visualization of the data which are stored in tables of attributes made possible to show legibly the distribution of I. ricinus on the analysed area. Mapping of I. ricinus occurrence on digital maps enable to indicate areas of the highest risk of biting and potential tick-borne diseases.
