Statistical Analyses

Statistical analyses of environmental data are absolutely essential with rapidly expanding data volumes. Environmental statistical methods are used, for example, to interpret and visualise data flow, to fill in missing values on the basis of statistical models, and to isolate the causes of fluctuations in the data. mehr lesen


are dynamic emission registers with which largely static locations emission sources can be linked with emission-determining factors varying with time within a geographical information system (GIS), so that updates and extrapolations of registers can be carried out quickly and easily. mehr lesen

GIS Integration

IVU Umwelt integrates models and our models in Geographical Information Systems (GIS). Thus, GIS data is directly available for environmental planning, opening up new possibilities in analysis and display.
