Helicopter Project to Map North Holland Soil Begins August 15
Haarlem, Monday, 11 August 2025.
Starting August 15, a helicopter-based project in North Holland will map soil up to 200 meters deep, informing environmental management and aiding local sustainability efforts.
Overview and Purpose of the Project
The helicopter-based soil mapping project is a crucial component of North Holland’s strategic plan to enhance environmental management and support sustainable development initiatives. This project aims to precisely chart the region’s underground features up to a depth of 200 meters. The information garnered from this project is expected to assist in sustainable groundwater management, safeguard public water sources, and reduce soil salinization risks, all of which are integral for the region’s long-term environmental resilience [1].
Collaboration and Execution
This endeavor is spearheaded by the FRESHEM-NL project, a collaboration between seven provinces, multiple regional water authorities, and a number of scientific bodies including Deltares and TNO - Geological Survey of the Netherlands. The project will be executed with advanced technology, using a helicopter flying at approximately 80 meters above ground with a sensor that emits electromagnetic signals to map the underground. Notably, these signals are harmless to people, animals, and nature [1][2].
Anticipated Benefits and Environmental Impact
Mapping the underground with such detailed precision is expected to yield several ecological benefits. In addition to enhancing local agricultural practices through better soil management, the project seeks to improve the region’s water systems by accurately identifying the location and composition of aquifers and clay layers. By doing so, it grants essential insights into where fresh, brackish, or saline groundwater resides, which can significantly influence water resource management and potentially curtail the progression of salinization [1].
Public and Environmental Considerations
Efforts have been made to minimize any negative impact or disturbance that could arise from the project. The helicopter routes are carefully planned to avoid flying directly over densely populated areas or during the breeding seasons of local wildlife. Despite these measures, some temporary noise disturbance may occur. The organizers assure compliance with all necessary legal permits, protecting sensitive areas and coordinating with local regulations [2].
