Tasks

Task 1: Creation of a geodatabase for a basic study area – the Carpathian Mountains

In this task we will create a geodatabase with satellite images (MODIS, Landsat, Ikonos) and satellite land cover maps; digital elevation models (SRTM DEM); road and river networks for the basic study area; the Carpathians.
The geodatabase will be used in the subsequent tasks.

Task 2: Development of a new approach for a landscape structure representation: Landscape Integrated Models

In this task we will test, adapt and combine existing mathematical and physical methods (morphological analysis, surface metrology, lacunarity analysis, texture analysis, spectral and wavelet analysis) for modeling of a landscape structure using an integrated, patch-gradient-based representation. This task will be implemented in four steps:

Task 2a: critical review and testing of methods of landscape structure investigation based on categorical- and gradient-based models,
Task 2b: development of a new integrated landscape structure representation: Landscape Integrated Models using mathematical and physical methods,
Task 2c: comparison of the new approach of landscape structure representation with the models from the task 2a,
Task 2d: assessment of scale impacts on results of the tasks 2b.

Task 3: Development of new approaches in landscape and habitat fragmentation assessment

In this task we will develop a new approach (a collection of metrics) for assessment of landscape fragmentation. The new measures will be based on the new landscape structure representation developed in task 2 (LIM) and on existing mathematical and physical methods (surface metrology, lacunarity analysis, texture analysis, spectral and wavelet analysis, morphological analysis, statistical analysis, distance analysis). This task will be executed in four steps:

Task 3a: critical review and testing of accessible approaches for a landscape fragmentation assessment,
Task 3b: development of the new approach for landscape fragmentation assessment based on the LIM and using mathematical and physical methods,
Task 3c: comparison of the new approach (metrics) of landscape fragmentation assessment with existing methods described in the task 3a,
Task 3d: Assessment of scale impact on the results of the tasks 3b.

Task 4: Development of new approaches in landscape and habitat connectivity (structural and potential) assessment

In this task we will focus on development of a new approach (e.g., a collection of metrics) for assessment of landscape connectivity. We will analyse two types of connectivity: structural and potential. The new methods will be created based on the new landscape structure representation developed in task 2 (LIM) and on existing mathematical and physical methods (surface metrology, lacunarity analysis, texture analysis, spectral and wavelet analysis, morphological analysis, statistical analysis, distance analysis, and graph theory). This task will be accomplished in four steps:

Task 4a: critical review and testing of accessible approaches for a landscape connectivity (structural and potential) assessment,
Task 4b: development of the new approach for landscape connectivity (structural and potential) assessment based on LIM,
Task 4c: comparison of the new approach (metrics) of landscape connectivity (structural and potential) assessment with existing methods described in the task 4a,
Task 4d: Assessment of scale impact on the results of the tasks 4b.

Task 5: Testing the universality of approaches developed in the tasks 2-4

In this task we will implement the methodologies from tasks 2-4 in the supplementary study areas to check universality and evaluate our models and measures. This task will be implemented in two steps:

Task 5a: Creation of geodatabases for the supplementary study areas: the Alps, the Appalachian Mountains and the Rocky Mountains,
Task 5b: Assessment of the universality of new approaches from tasks 2-4 in the supplementary study areas.
