GIS Data Sources

  • International
    • Compendium of Environmental Sustainability Indicator Collections
      There have been a number of initiatives in recent years to generate indicators of national-level sustainability, resilience, and vulnerability, yet obtaining the data behind these efforts is often difficult. Even where data are publicly available for download, combining them with other indicators or ingesting them into other databases can be problematic. Through this compendium SEDAC has sought to make the acquisition, comparison, and analysis of sustainability indicators easier by compiling them in a single database, incorporating multiple country codes, and condensing the indicator descriptions into short methodological summaries in an accompanying metadata database.
