Landslide risk mapping
SGI conducts landslide risk mapping along prioritised watercourses in Sweden. The work began with an investigation along the country’s largest river, the Göta River.
Maps and tools
SGI carries out GIS analyses, 3D modelling and system development related to landslides, erosion, as well as vulnerability and climate change adaptation.
Maps, GIS and geodata
Parts of our mapping and analysis work result in WMS data services. These are registered and described in our map viewing services and in the Geodata Portal hosted by Lantmäteriet (the Swedish mapping, cadastral and land registration authority).
Tools
SGI has developed tools to support this work. The tools consist of software applications or templates. A few examples of maps and tools are shown below.
Coastal vulnerability index
The coastal vulnerability index indicates the potential for coastal erosion and the societal values at risk. The tool can be used as a support in municipal planning processes, as well as in other forms of spatial planning.
Nature-based erosion protection
SGI have gathered experiences of nature-based erosion protection in Sweden to provide inspiration and ideas for how they can be designed.
Map data on landslides and erosion in a web-based map viewer
Urban and regional development must be planned and adapted to local ground conditions and future climate change. Knowledge about landslides and erosion is essential for making sustainable decisions, avoiding economic losses, and preventing accidents.
Several Swedish authorities produce map data to support analysis of conditions related to landslides and erosion. SGI Guidance 1 (in Swedish) describes how this data can be used and interpreted. The datasets are presented in a web-based map viewer and further described in related product sheets (in Swedish).
Through the map viewer, Swedish authorities jointly highlight key data on landslides and erosion in support of a more integrated digital planning process. The aim is to assist municipalities and regions in developing digital planning tools.
