This is a collection of administrative boundaries for all NRC country field operations. Each country has varying levels of administrative boundaries.

This was compiled from various sources including: GADM, GeoBoundaries, and UN sources.¹

Administrative boundaries are organized by:

• NRC Region
• Country (ISO 3166 Alpha 3)
• Levels of granularity (i.e ADM 0-4)
• Data formats (.geojson, .shp, .csv)

¹ The main source of data is from Runfola, D., Seitz, L., Hobbs, L., Panginaban, J., Oberman, R. et al. geoBoundaries Global Administrative Database. http://www.geoboundaries.org.

How the data is organized

The collection uses the following folder structure:

• [RO-NAME]
  • [3-LETTER-ISO-CODE]
    • [ADM-LEVEL]
      • [FILE-FORMAT]

Region

Under the Region folder, a .geojson file can be found for each NRC region. These are made up of a series of country boundaries (ADM0) that were appended together for easy visualization purposes.
