Heat Analysis
We identify urban heat islands, highly exposed areas and priority zones for greening, de-sealing, shading and other climate adaptation measures.

Services
Following are the all Blue4Green service
Water Monitoring
We monitor key indicators of surface water quality, including chlorophyll-a concentration, viewing depth, turbidity, algae growth, algal blooms and water temperature. This supports cities and municipalities in continuously observing, assessing and sustainably managing their water bodies.
Shading Analysis
We identify shaded and highly heat-exposed areas. This enables cities to assess where existing shading already provides relief and where additional shading measures would be most effective.
Irrigation Management
We identify drought stress and seasonal changes in urban vegetation. This enables cities to plan irrigation measures more precisely, use water resources more efficiently and prioritise the most affected areas.
Resilience Analysis
We provide timely insights into the vitality, growth and vegetation period of urban green spaces. This enables cities to identify which green structures remain resilient even under adverse weather conditions and use these insights for maintenance, adaptation and the planning of new green spaces.
Tree Mapping
We detect individual trees using high-resolution terrain and surface models, precisely locate tree positions and automatically delineate tree crowns. This helps municipalities create and update tree inventories, calculate canopy cover, and better plan and document measures.
Urban Green Tracker
We monitor urban green spaces and tree canopy cover over time and document changes and losses in urban greenery. This provides municipalities with a reliable basis for planning, reporting and measures related to the EU Nature Restoration Regulation.
Ecological Connectivity
We analyse how well green spaces, habitats and tree structures are connected across urban areas. This enables municipalities to strengthen ecological corridors, identify barriers and plan measures to support biodiversity more effectively.
Green Roof Potential
We identify suitable roof areas for greening measures and assess their suitability based on roof slope. This enables municipalities and planning offices to map potential areas, prioritise measures and prepare targeted green roof programmes – also in the context of the EU Nature Restoration Law, helping to make cities greener and more resilient.
