  5. 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

  6. 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.)

  7. 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)

  8. GITAN – Example Indicators and Trends Metrics Land Cover, Land Use, and Ecosystems Forests (and other Land Cover) Percent Tree Cover Impervious Surface Ecosystem Extent Landscape Patch Size Distribution Patch Vulnerability Protection Percent of Ecoregions/Ecosystems Under Protection Threats Land Use and Land Cover in and near Protected Areas Urbanization and Infrastructural Development Water Surface Water Extent Socio-economic Demographic Patterns

  9. Great Basin Appalachian/Blue Ridge Cardamom Mountains/Southeastern Indochina Dry Evergreen Forests West Sudanian Savanna/ Guinean Savanna-Forest Complex Chaco

  10. GITAN Concept Matrix • Thematic Modules • Geographic Pilots • Extensible Business Model
