Getting started

Search an address — type any Danish address in the search bar at the top. Pick a result from the dropdown to fly to that location and start the analysis.

Or click the map — tap any point on the map to get a full climate risk breakdown for that exact location. A pin will appear and data starts loading automatically.

Read the Assessment — once the analysis finishes, the sidebar shows your overall climate score plus individual risk factors. Click any row to expand it and see detailed explanations, data, and maps.

Explore Regional Climate Guide — scroll down in the Assessment to find the decade-by-decade regional outlook panel. Switch between 10 domains (sea level rise, AMOC, insurance, cost of living, etc.) and slide through years 2030–2100 to see how risks evolve over time.

Toggle map layers — use the floating buttons on the left side of the map to add Elevation, Flood Zones, Soil, Climate Score, Groundwater, Wind Turbines, Solar Farms, Land Use, Noise, Aerial Photo, and more. Combine layers to build a complete picture.

Use your location — tap the ◎ button on the map to analyse where you are right now.

What the score means

Every location gets a climate score from 5 to 95. Higher is safer. The score combines elevation, coast distance, soil type, topographic position, waterway proximity, and urban surface into a single number.

75–95 Good — Elevated ground, far from coast, good drainage. Low climate risk.

62–74 Acceptable — Some risk factors but manageable overall.

48–61 Moderate risk — Worth investigating specific factors before buying.

35–47 Elevated risk — Multiple risk factors present. Consider a professional flood survey.

20–34 High risk — Likely already affected or highly vulnerable to flooding.

5–19 Very high risk — Serious concern. Professional assessment strongly advised.

The 6 risk factors

Each location is assessed against six independent factors. Expand any row in the Assessment tab to see detailed data for each one.

⛰

Sea flooding — how high above sea level and how far from the coast. Below 4m and within 5km is a serious risk zone, especially as sea levels rise 0.5–1.6m by 2100.

🌧

Rain & runoff — Danish cloudbursts can drop 72mm in an hour. On clay soil, nearly all becomes surface water. Low-lying spots fill up fast.

⛰

Topographic position — whether you sit in a hollow where water collects, or on elevated ground where it drains away. Analysed using a 7×7 elevation grid around the point.

🌎

Waterways — proximity to rivers, streams, and ditches. The tool checks if the water surface is higher or lower than the property and estimates flood surge range.

🪨

Soil drainage — clay (most of Sjælland) is nearly impermeable. Sandy soil drains better. In cities, stormwater systems partially compensate for sealed surfaces.

⚓

Coast distance — how far from the nearest coastline. Properties within 3km face storm surge risk; within 8km are exposed to salt spray and coastal climate effects.

Regional Climate Guide

Below the risk factors in the Assessment, you’ll find a decade-by-decade climate outlook covering 10 domains. This goes beyond physical flooding to show how climate change may affect your property and life in Denmark over the coming decades.

🌊

Sea Level Rise — how much the sea rises decade by decade and what it means for your elevation.

🫍

AMOC — the Atlantic current keeping Denmark warm. If it weakens or collapses, winters could get 5–10°C colder.

⛈

Extreme Weather — cloudbursts, storms, and groundwater rise. Denmark faces triple water pressure.

🌽

Food Security — how warming (or AMOC collapse) affects Danish agriculture and food prices.

💲

Insurance — Denmark’s solidarity scheme and its growing coverage gaps.

🏛

Government — adaptation plans, infrastructure investments, and the implementation gap.

🔥

Tipping Points — cascading climate thresholds that could trigger irreversible changes.

🩹

Health — heat stress, tick-borne disease, wildfire smoke, and mental health impacts.

⚔

War & Conflict — Arctic geopolitics, migration pressure, and indirect risks to Denmark.

📈

Cost of Living — how energy, food, insurance, and taxes may change for your household.

How to use it: Click any domain button to switch topics. Click a decade (2030–2100) to see projections for that year. The consequence table is cumulative — later years show all earlier consequences too, so you get the full picture by 2100. Hover over any consequence for more details. Severity is colour-coded: minor, moderate, severe, critical.

Map layers

Toggle layers using the buttons in the top bar. You can combine multiple layers at once.

Elevation

Colours every point by height above sea level. Red = 0–3m (danger), yellow = ~12m, green = ~30m, blue = ~55m, violet = 100m+.

Flood Zones

Shows terrain below the selected water level. With a free Dataforsyningen token, switches to Denmark’s official river overflow model (DHM) at 0.4m LiDAR accuracy. Use the slider at the bottom to change the modelled water rise (0.5–6m).

Terrain

Contour lines showing the shape of the land. Lines close together = steep slope (water runs off). Lines far apart = flat (water may pool).

Soil / Geology

Denmark’s geological map (GEUS). Blue/grey = clay (water can’t soak in), tan = sandy (drains well), green = peat & wetland. Zoom in for field-level detail.

Climate Score

A heatmap showing the climate resilience score for every location on the map. Green = safe, amber = moderate, red = high risk. Great for comparing neighbourhoods at a glance.

Groundwater

Depth to groundwater from the TELEGRAAF model (MiljøGIS). Red = shallow (<1m, high risk for basements and foundations), yellow = moderate (2–3m), blue = deep (5m+, low risk). ~500m native resolution — looks blocky when zoomed in close.

Wind Turbines

Two data sources combined: blue circles show existing turbines from OpenStreetMap (with capacity and height when known), and the shaded zones show adopted wind turbine planning areas from Plandata.dk. Useful for assessing visual impact and noise when buying near open land.

Solar Farms

Amber circles mark existing operational solar farms (OpenStreetMap), while shaded zones show adopted solar farm planning areas (Plandata.dk). Indicates areas where large-scale solar development is permitted or already underway — relevant for rural properties.

Land Use

Municipal zoning framework (Kommuneplanramme) from Plandata.dk. Colour-coded by category: orange = residential, red = town centre, cyan = commercial, green = recreation, yellow = summer cottages. Shows what development is legally permitted in each area.

Traffic Noise

EU Environmental Noise Directive (END) data from MiljøGIS, showing road, motorway, rail, metro, and airport Lden noise levels. Yellow = 55–59 dB, orange = 60–64 dB, red = 65–69 dB, dark red = 70–74 dB, purple = 75+ dB. WHO recommends below 53 dB for sleep.

Aerial Photo

Dataforsyningen spring ortofoto at 12.5cm per pixel resolution — Denmark’s official aerial photography. Far more detail than satellite imagery. Ideal for inspecting garden drainage, proximity to waterways, and the actual building footprint. Toggle off other layers for the clearest view.

The Denmark trap

A house can be 20m above sea level and still flood regularly if it sits in a natural bowl on clay soil. Sea-level risk and rain-flood risk are separate problems — always check both, especially if the topographic position shows a depression.

Tips for buyers

• Compare several addresses in the same area — scores can vary dramatically within a few hundred metres.

• Turn on the Elevation layer and look for pockets of red/yellow near your address — these are low spots where water collects.

• Check the Flood Zones layer at 1.0m and 2.0m to see what a realistic sea level rise scenario means for the area.

• In the Regional Climate Guide, check Insurance and Cost of Living — these directly affect your long-term finances.

• Hover over consequences in the cumulative table for extended explanations with Danish-specific context.

Limitations

• Elevation data is from open satellite sources (~10–30m resolution). For precise readings, use Denmark’s 0.4m LiDAR via Dataforsyningen.
• Coast distance is estimated from OpenStreetMap coastline data.
• Clay zones are broad regional estimates — local soil can vary significantly.
• Climate projections reflect ranges from peer-reviewed literature. Actual outcomes depend on global emissions, policy decisions, and natural variability.
• This tool provides indicative guidance only, not a professional flood survey or financial advice.
