European Landscape Classification (LANMAP) Notes
Introduction
- Europe features a long, complex coastline and diverse elevations including mountains and lowlands.
- The region showcases various geological and soil types, as well as a wide range of climates from Arctic to Mediterranean.
- Historical analyses (e.g., pollen studies) illustrate the evolution of vegetation tied to land-use changes over 7000 years.
- Characteristics of European landscapes are diverse, ranging from pristine environments (e.g., Svalbard) to engineered landscapes (e.g., Dutch polders).
- Landscapes are defined as units of Earth's surface with distinct characteristics and significant ecological interactions.
Importance of Landscape Classification
- Understanding landscapes is crucial for assessment, management, and protection due to their ecological and cultural significance.
- Current challenges include landscape homogenization and loss of character driven by demographic and economic pressures, climate change, and land-use transforms.
- The European Landscape Convention emphasizes the role of landscape as a vital element in social well-being.
LANMAP Development
- LANMAP provides a hierarchical framework for European landscape classification, addressing the need for spatially explicit and comprehensive maps.
- The classification is based on high-resolution data concerning climate, altitude, parent material, and land use.
- LANMAP features four levels of hierarchy:
- Level 1: Climate-based classifications (8)
- Level 2: Climate and altitude (31)
- Level 3: Climate, altitude, and parent material (76)
- Level 4: Comprehensive classification with land cover (350 landscape types).
- Each landscape type comprises approximately 14,000 mapping units (min. 11 km²).
Methodology and Framework
- A transparent methodology was developed that prioritizes:
- An objective and consistent approach
- Flexibility and user-oriented design to accommodate various end-user needs
- Use of GIS for handling extensive datasets efficiently.
- The frameworks incorporate:
- A common conceptual approach aligned with stakeholder inputs and scientific rigor.
- Developing a standardized classification system to aid in biodiversity and environmental assessments.
Key Components and Factors of Landscape
- Landscape components include abiotic (climate, geology) and biotic (vegetation, fauna) elements that contribute to the ecosystem's structure.
- The relationships between these components are crucial for assessing landscape dynamics and changes.
- Factors like land use, cultural history, and population density must be integrated but currently lack sufficient data for accurate representations.
Data Acquisition and Integration
- Successful landscape classification relies on high-quality datasets from various sources, including:
- Climate data: European Environmental Stratification
- Altitude: Digital Elevation Models
- Parent material: European Soil Database
- Land cover: CORINE Land Cover database and others.
- Challenges exist due to the disparity in data resolution and the need for integration across multiple datasets.
Segmentation and Typology Construction
- Object recognition techniques and segmentation methods were employed to delineate landscape units effectively from satellite imagery.
- A two-step approach was applied:
- Initial segmentation based on static layers of altitude and parent material.
- Refined segmentation including dynamic land cover data.
Validation and Comparisons
- Validation involved cross-comparisons with national landscape classifications (e.g., Dutch, Spanish).
- Observations showed LANMAP to be less detailed than some national systems but generally consistent in broader patterns.
- National classifications vary greatly in methodology and thematic emphasis, limiting direct comparison with LANMAP.
Results
- LANMAP, covering about 11 million km², represents a significant advancement in landscape classification at a European scale.
- The average landscape unit size is approximately 774 km², with notable differences in sizes across regions.
- The hierarchical classification structure aids in addressing various environmental monitoring and reporting needs.
Applications and Future Directions
- LANMAP's utility spans across educational purposes, environmental assessments, and biodiversity studies.
- Future improvements could include integrating cultural-historical data and enhancing ecological metrics.
- LANMAP aims to facilitate cross-boundary landscape management and promote consistency in landscape assessment practices across Europe.
