What's new – New powerful tool for emergency response and coastal flood prevention

Feb 16, 2018

SCALGO Live has proven a valuable tool for emergency responses under multiple different flood events in Denmark in 2017. With this release, we enhance your ability to visualize, prioritize, and plan coastal protection. Using the new "Critical Points" analysis (available with "Sea-Level Rise" layers), users can visualize the vulnerable points where seawater can intrude and flood low-lying areas beyond. The critical points might be dimples in dykes, or a natural water path, e.g. a small stream of particular interest for flood prevention.

The feature is also available in workspaces, where users can test the effect of barriers at the critical points and generate new vulnerability maps of the critical points that may emerge after placement of these barriers.

Critical points are ranked by the size of the area at risk, that is, the area that is flooded if the seawater rises above the critical point. Using a slider, points associated with a low area at risk can be filtered out.

A critical point (black circle) marks a point that protects 1.7 hectares of land behind it and which is flooded at a sea level of 85.4cm.

Download watersheds as vectors

By popular request, you can now download vectorized watersheds in SCALGO Live. When you select the download button next to a watershed layer, the UI will ask you if you want a vectorized output or the raw watershed raster. Note that the vector output is not simplified so the polygons can be fairly large.

Denmark: Models and analysis update

We have updated the elevation models and the analysis products (flash flood map, flow accumulation, watersheds and sea-level rise) to include newer buildings from GeoDanmark - acquired on November 19 2017 from Kortforsyningen. Your existing workspaces have not been changed.
