Client: CENTROZŁOM WROCŁAW S.A.
Location: Grodków, Poland

Roughly 60 kilometers (37 miles) south from the city of Wrocław is the town of Grodków in the Opole region of Poland. Grodków is steep in history and is the location of a former WWII German air base. Today, there is not much left of the base. Only small traces of above ground indicators hint at the location where hangars once stood and concrete slabs reveal the past existence of buildings.
In support of environmental management and cleanup efforts, GISonLine was pleased to take part in providing underground detection services to identify the location of buried objects, storage tanks, and old munitions at the Grodków site.

The Impact

GISonline performed aerial drone surveys to collect high-resolution color imagery that enabled the production of detailed orthophoto maps. The orthophoto maps provided visualization of current site conditions along with the spatial mapping of above ground objects and remaining infrastructure. Ground Penetrating Radar (GPR) surveys were also conducted to identify objects and assets that were buried beneath the ground such as old storage tanks and munitions.

The Outcome

GISonLine successfully completed the Grodków site surveys and produced key deliverables such as 2D and 3D mapping products. The up-to-date mapping products and underground detection surveys were used to identify the precise location and depths of buried objects. Together with the high-resolution aerial imagery, a complete site picture depicting above and below ground assets was made possible in support of planning and environmental management efforts.

Client: EXACT
Location: Stockholm, Sweden

In support of a planned industrial complex near the Stockholm city center, GISonLine, together with its partner (EXACT) performed above and below ground surveys to create a comprehensive digital representation of the existing and planned infrastructure.

The Impact

As part of the above and below ground surveys, the GISonLine underground detection team collected data covering an area of over 12,000m2 using multiple detection sensors and methods such as ground penetrating radar (GPR), electromagnetic locators, location probes, and inductive measurements. In addition, the EXACT team collected point cloud data using terrain laser scanning obtained from drone platforms and data collections.

The Outcome

GISonLine successfully conducted the underground surveys to provide the client with a complete survey and 3D model on the location, depth, and characteristics of the existing utilities network. Key mapping products were created and delivered that provided 2D maps and 3D models for advanced visualization of the utility networks.

The models of the underground utilities were integrated with the above ground scanning (point cloud datasets) to form a highly accurate 3D model and representation of the industrial area.
