Deadly legacy; [Tödliches Erbe]

Abstract

This article examines the lasting effects of past activities and decisions that can create serious environmental and spatial challenges over many years. The idea of a deadly legacy is considered from the perspective of how geospatial information, mapping, and digital technologies can help identify, understand, and manage risks associated with historical sites, infrastructure, land use, or environmental damage. Such problems are often difficult to assess because their causes may lie far in the past while their consequences remain visible in the present. Geographic data can provide an important basis for locating affected areas, comparing different sources of information, and supporting responsible decisions. GIS can bring together information from maps, databases, remote sensing, surveys, and other sources to create a clearer picture of spatial relationships. The article also highlights the importance of reliable data when authorities and professionals need to assess risks and communicate them to the public. Digital mapping can make complex relationships easier to understand and can support planning, monitoring, and remediation activities. At the same time, historical information may be incomplete or inconsistent, requiring careful interpretation. The discussion shows that modern geospatial methods are not only tools for describing current conditions but can also help society deal with problems inherited from earlier periods. Better spatial information can therefore contribute to safer planning, improved environmental management, and more informed decisions about areas affected by a difficult legacy. The example also underlines the need to preserve historical information and make it usable for present-day planning and risk reduction.
