Thematic content

As was already shown in the interaction, the thematic content of the map can either be taken from existing sources or it is being newly generated from own acquisitions or samples. The many data sources of thematic data and the detailed explanation of acquisition and sampling methods are described here (German version only).

Data quality is an important aspect, independently of the data source and mode of acquisition. Before these data are further used, the following criteria have to be evaluated:

  • Accuracy
  • Coverage
  • Completeness
  • Actuality
  • Correctness
  • Reliability & plausibility
  • Validity
  • Readability, data format
  • Maintenance
  • Provenance

Based on these criteria it is to be decided if the data are in fact suitable to present a topic in sufficient accuracy and in adequate form.
