BFPaaS – GREY

An ESA demonstration project, developed in a consortium with dlapilota and WIZIPISI. The solution evolved into a commercial portal. The project’s basic scope includes terrain profile analysis along the planned BVLOS flight route, performed using the latest Copernicus Sentinel 1 satellite radar imagery and other available data sources (e.g. national/public or commercial repositories).

The GREY tool is intended to support the aviation sector from UAVs through manned aviation and air medical services (HEMS) to general aviation and authorities, but potential use cases also include crisis management, spatial planning, infrastructure monitoring.

The basic use case involves providing actual and accuracy-adjusted terrain profiles to aviation authorities and commercial aviation companies, for example, for low altitude/low visibility flight planning or monitoring of terrain obstacles or unsupervised landing sites that require instant terrain protection for Instrumental Procedures.

GREY spatial data repository:

• DSM (Digital Surface Model) 0.5×0.5m/1x1m
• Database of topographic objects (topographic map)
• Dedicated map of identified slender objects
• Results of satellite-based terrain profile analysis
• Risk map (25x25m) – (with option to personalize risk analysis formulas)
• Option to add other data sets/layers as needed
• Currently, full coverage of Poland with option to extend to any other country
• Quick and reliable access to data and analytical results
• Continuous data updates

Selected examples of GREY use cases

• Terrain profile analyses along and in the vicinity of planned routes of UAV BVLOS missions
• Analysis of terrain objects and population-related risks
• Search and rescue operations field support for Crisis Management
• Spatial Planning support for municipalities
• Initial line-of-sight survey option for telecom microwave links planning
• Environmental analyses support.
