摘要：The paper presents the methodology for processing and integrating data that originate from various sources and periods. In the first stage of works conducted under the research project No. N304 077 31/3060 financed by the State Committee for Scientific Research and titled "Spatial Modelling of Changes in Selected Elements of the Słowiński National Park," archival and current aerial photos from 1951-2004 were subjected to processing. The photogrammetric material was then used to prepare a Digital Terrain Model (DTM),and next,to generate orthophotomaps for all annual files. As a result,particular DTMs became the grounds for analyses of changes in land configuration resulting from dynamic eolian processes that take place in the coastal zone and in the belt of migrating dunes,which exist within the Słowiński National Park (the SNP) territory. Vectorial map layers under the "1965" coordinate system constituted an important source of information on the investigated area (including,among other things,thematic layers: geodesy,topography,geology, hydrology,flora,fauna,and other – all in the dgn format),and the same about tabular descriptive data (the MS Access format),concerning particular elements of the SNP environment. The descriptive data required proper processing and combining with thematic vectorial maps. In another stage of research, multitemporal image data for the investigated area and thematic layers were integrated in GeoMedia (GeoMedia Professional,GeoMedia Grid) environment,which allows to read and process various format data. The integrated spatial and time data enabled a comprehensive examination of those factors,which contribute to constant changes in the Park landscape and environment. Satellite photos provided a valuable supplement to the database. Images from the ASTER and LANDSAT satellite (under the UTM system) were utilised to generate images of the vegetation index,land use/coverage maps,as well as colourful compositions. The satellite data was processed with the use of ENVI (Environment for Visualizing Image) software. Finally,the database created that way made it possible to perform complex analyses of changes occurring in the SNP area.
