Airport Green Inventory

The airport green inventory encompasses a comprehensive environmental and conservation assessment aimed at accurately surveying, documenting, and cataloguing green spaces and dendrological values. This information is then implemented into an IT system to support decision-making and planning. Special attention is given to the presence of native species, both in local tree populations and grassland areas. We assess the resilience and adaptability of grasslands, shrublands, and forest habitat complexes in the context of climate adaptation. We catalogue values of natural heritage significance, examining their ecological and economic importance and health. Managing green areas—with particular focus on preserving biodiversity and maintaining ecosystem services—becomes a fundamental aspect of sustainable airport operation. Within the Greenport project, integrated information systems and spatial databases are developed to allow precise recording and comprehensive analysis of environmental data. This enables airport operators to manage green areas more effectively, reducing environmental impact and contributing to sustainability goals. The timing of interventions can be predicted, and costs become more manageable. Our IT and data collection solutions also provide opportunities for landscape rehabilitation projects and habitat reconstructions. Such assessments form the basis for developing airport environmental strategies, contributing to the protection and enhancement of local and regional ecosystems.

Different types of environmental and conservation assessments are required for airports of various sizes and categories. Our expert team assists in accurately assessing needs and determining the scope of necessary operations.

eTOD - electronic terrain and obstacle data collection

eTOD (electronic Terrain and Obstacle Data), as defined by ICAO Annex 15, covers electronic terrain and obstacle data collection for aviation safety. Surveys are prepared with remote sensing, geodetic, and geoinformatics methods, with documentation, quality assurance, and aviation-law support also connected to the professional role of Erenfield Ltd.

Terrain and obstacle data are classified according to the relevant surfaces and requirements: Area 1, Area 2a, Area 2b, Area 2c, Area 3, and Area 4. The results can be prepared for regulatory upload and can also be delivered as an airport GIS database.

Heliports (FATO)

Heliport obstacle databases are prepared around the Final Approach and Take-off Area (FATO), taking the obstacle limitation surfaces into account. Operations in the approach and take-off zones must remain safe even in crosswind conditions, so several operational scenarios need to be evaluated when defining the obstacle surfaces.
