  • Pacific Data Hub
    The Pacific Data Hub (PDH), is a central repository of data about the Pacific and from the Pacific. The platform serves as a gateway to a collection of data and information about the Pacific across key areas including population statistics, fisheries science, climate change adaptation, disaster risk reduction and resilience, public health surveillance, conservation of plant genetic resources for food security and human rights.
  • Pacific Environmental Data Portal
    The Pacific Environment Portal provides an easy way to find, access and reuse regional and national data. It's purpose is to provide access and safe storage for environmental datasets to be used for monitoring, evaluating, and analyzing environmental conditions and trends to support environmental planning, forecasting, and reporting requirements at all levels. The Portal is part of the Pacific Data Ecosystem, a partnership between Pacific Island Countries, SPREP and SPC. It automatically pulls in data from national repositories. The countries retain data ownership.
  • Pacific Islands Ocean Observing System (PacIOOS) Voyager
    An interactive map interface for visualizing and downloading oceanographic observations, forecasts, and other geospatial data and information related to the marine environment and beyond. Primary geographic focus at PacIOOS is on Hawaiʻi and other U.S.-affiliated Pacific Islands throughout Polynesia and Micronesia: American Samoa, Commonwealth of the Northern Mariana Islands,  Federated States of Micronesia, Guam, Hawaiʻi, Republic of the Marshall Islands, and Republic of Palau.

  • Dynamic World
    "Near realtime 10m resolution global land use land cover dataset, produced using deep learning, freely available and openly licensed. It is the result of a partnership between Google and the World Resources Institute, to produce a dynamic dataset of the physical material on the surface of the Earth. Dynamic World is intended to be used as a data product for users to add custom rules with which to assign final class values, producing derivative land cover maps." -- Dynamic World

  • Google Earth Engine
    "Google Earth Engine is a cloud computing platform for processing satellite imagery and other geospatial and observation data. It provides access to a large database of satellite imagery and the computational power needed to analyze those images. Google Earth Engine allows observation of dynamic changes in agriculture, natural resources, and climate using geospatial data from the Landsat satellite program, which passes over the same places on the Earth every sixteen days. Google Earth Engine has become a platform that makes Landsat and Sentinel-2 data easily accessible to researchers in collaboration with the Google Cloud Storage. Google Earth Engine provides a data catalog along with computers for analysis; this allows scientists to collaborate using data, algorithms, and visualizations. The platform provides Python and JavaScript application programming interfaces for making requests to the servers, and includes a graphical user interface for developing applications." -- Wikipedia
