For decades, alpine ski resorts have faced a hidden million-euro challenge: efficient snowmaking under unpredictable weather conditions. At Planai-Hochwurzen in Austria, this challenge has now been transformed through automated drone operations powered by DJI Dock 3 and the DJI Matrice 4TD.
Instead of sending teams on snowmobiles into freezing night conditions, the resort now relies on automated drone missions — improving safety, efficiency, and sustainability.
Snowmaking operates most efficiently in the coldest hours - typically between midnight and dawn. But these conditions create a visibility paradox: the optimal time to make snow is also the worst time to monitor it.
Ground crews driving snowmobiles cannot see where spray is landing in darkness or heavy snowfall. By the time inefficiencies become visible in daylight, thousands of euros in water and energy have already been wasted.
Wind presents the greatest variable. A gust can redirect an entire snow gun's output onto trees or bare rock within seconds. Without real-time awareness, operators have no way to respond.
The Matrice 4TD's thermal camera solves the visibility problem by reading surface temperatures.
On the thermal display, operators see a clear temperature contrast: the warmer ground appears in one shade, while fresh artificial snow - significantly colder - shows as distinct bright spots where it accumulates.
When wind pushes snow off the intended piste, the thermal signature reveals it instantly. Operators watching the live feed can recalibrate the affected snow gun remotely, redirecting the spray back on target within minutes.
The practical impact: resources go exactly where planned, and waste drops dramatically.
Mountain weather is unpredictable—conditions can shift in minutes. The DJI Dock 3 facilitates preprogrammed daily and nightly flights that continuously record changes in snowpack and infrastructure.
The technical workflow is managed through FlightHub 2, where KML files containing the exact coordinates of every snow gun enable automated route planning. Once programmed, the system executes missions without manual intervention.
While the drone captures thermal data, operators need to know exactly which snow gun requires attention. This is where KIONIQ's SPECT software comes in.
SPECT is the platform used by Planai to overlay drone data with snow gun coordinates. The integration works as follows:
1. The Matrice 4TD captures thermal imagery with embedded GPS data during its automated flight.
2. FlightHub 2 syncs this data to software SPECT from the drone service partner KIONIQ.
3. SPECT displays the thermal footage overlaid on a map showing piste boundaries (in red) and snow gun locations (as yellow dots).
4. Operators can see clearly on the thermal image whether each snow gun's spray is directed correctly onto the piste—or if recalibration is needed.
This data integration transforms raw aerial footage into actionable maintenance decisions.
Planai-Hochwurzen spans peaks and valleys. A single dock cannot provide adequate coverage for the entire resort.
The Dock 3's dock hopping capability addresses this limitation. A drone can launch from one station, execute its mission, and land at a different dock elsewhere on the mountain. After recharging, it deploys again from the new location.
This creates a relay system where the drone moves progressively across terrain, recharging at the nearest station rather than returning to its origin. Coverage extends across the full resort without manual repositioning.
The feature also supports task transitions. A drone monitoring snowmaking on one slope can hop to a dock near the cable car system and begin infrastructure inspection on the same deployment cycle.
While the immediate focus is snowmaking, the Dock 3 infrastructure establishes a multi-purpose ecosystem. The same technical workflow is now being expanded to include:
Infrastructure Inspection: Checking cable cars and lift systems for safety.
Avalanche Prevention: Supporting artificial avalanche forecasting and pre-checking slopes for hazards.
Search and Rescue: Utilizing thermal and zoom cameras to locate missing persons in difficult terrain.
Summer Trail Maintenance: Monitoring hiking paths and mountain bike trails during warmer months.
The dock becomes a permanent piece of resort infrastructure rather than a single-purpose tool.
Ski resorts across the Alps face the same pressures: shorter natural snow seasons, rising energy costs, and tighter margins. The Planai deployment demonstrates that automated monitoring infrastructure pays for itself through operational efficiency gains.
In an era of climate variability, this digital transformation ensures that resorts remain both sustainable and economically viable. The Dock 3's versatility means the same infrastructure serves winter snow management and summer maintenance across the entire resort footprint.
