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
1.1. BuildBuild consortium-based consortium-based partnershipspartnerships between contributors and users between contributors and users
2.2. Develop information resourcesDevelop information resources (satellite imagery and land use, (satellite imagery and land use, biophysical and sociocultural data, change and trends analyses, biophysical and sociocultural data, change and trends analyses, supporting plot-level datasets, etc.)supporting plot-level datasets, etc.)
3.3. Deliver information resourcesDeliver information resources into the public domain on the web and into the public domain on the web and in DVD formatsin DVD formats
4.4. Leverage the information resourcesLeverage the information resources as essential components of as essential components of global, continental, and regional earth observation and conservation global, continental, and regional earth observation and conservation monitoring programs (IABIN, GEOSS, etc.)monitoring programs (IABIN, GEOSS, etc.)
