GITAN – Global Integrated Trends Analysis Network • A multidisciplinary network of collaborators interested in understanding the types, causes, and consequences of change on the landscape • A framework for global planning and management applications • A global data development and analysis effort • An advisory resource for other networks and processes like IABIN, GEOSS, and CBD/COP-7
GITAN Approach • Build consortium-based partnerships between contributors and users • Develop information resources (satellite imagery and land use, biophysical and sociocultural data, change and trends analyses, supporting plot-level datasets, etc.) • Deliver information resources into the public domain on the web and in DVD formats • Leverage the information resources as essential components of global, continental, and regional earth observation and conservation monitoring programs (IABIN, GEOSS, etc.)
GITAN Core Information Resources • Satellite Imagery • 90 m Digital Elevation Data • Elevation Classes • Landforms • Landcover Maps • Landuse/Landcover Change Maps • Landscape Trends Analysis • Fragmentation Analysis • Ecosystems Maps and Ecosystems Services Analyses • Soils • Climate Data • Protected Area Data (WDPA) • Plot-based Measurements (STEP Database)
