The Gridded Population of the World, Version 4 (GPWv4): Population Density, Revision 11 consists of estimates of human population density (number of persons per square kilometer) based on counts consistent with national censuses and population registers, for the years 2000, 2005, 2010, 2015, and 2020. A proportional allocation gridding algorithm, utilizing approximately 13.5 million national and sub-national administrative units, was used to assign population counts to 30 arc-second grid cells.

The [Allen Coral Atlas](https://allencoralatlas.org/) combines high resolution satellite imagery, machine learning and field data to produce globally consistent benthic and geomorphic maps of the world's coral reefs. The Atlas is funded primarily by [Vulcan Inc.](https://www.vulcan.com) (founded by the late Paul G.

The Database of Island Invasive Species Eradications (DIISE) attempts to compile all historical and current invasive vertebrate eradication projects on islands. The vast majority of the dataset is focused on invasive mammals. Data gathered from each project includes island location and characteristics, details about the eradication including focal species, methods and outcome, plus links and or contact details for learning more about the project.
The Multi-national Geospatial Co-production Program (MGCP) is a coalition of over 30 countries dedicated to producing high-resolution topographic vector data throughout high interest areas of the world. Data is extracted from high resolution imagery in 1° x 1° cells at a scale of 1:50 000. All data produced must meet a minimum horizontal circular error accuracy of 25m and meet MGCP Technical Reference Documentation (TRD) specifications, which details extraction guidelines and feature catalogues to ensure consistency.
The GEOSS Portal is an online map-based user interface which allows users to discover and access Earth observation data and resources from different providers from all over the world.
The portal is implemented and operated by the European Space Agency and provides a single internet discovery and access point to the ever-growing quantities of heterogeneous collections of Earth observations from satellites, airplanes, drones and in-situ sensors at global, regional and local scales through the Global Earth Observation System of Systems (GEOSS).
GOA-ON works to improve our understanding of global ocean acidification conditions and ecosystem responses by making ocean acidification data easily accessible. This data portal contains platforms and products measuring ocean acidification parameters around the world.
The dataset contains a range of different Pacific regional maps developed by the SPREP GIS team and is available for use by members and partners.
The World Database on Protected Areas (WDPA) is the most comprehensive global database of marine and terrestrial protected areas, updated on a monthly basis, and is one of the key global biodiversity data sets being widely used by scientists, businesses, governments, International secretariats and others to inform planning, policy decisions and management.
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
A 10-meter resolution land surface digital elevation model (DEM) and derived hillshade for the islands of Palau from United States Geological Survey (USGS) 1/3 arc-second DEM quadrangles.
The PacificMap is a platform developed by CSIRO Data61 and the Pacific Data Hub (PDH) in collaboration with the Pacific Community Secretariat (SPC), as part of the Asia - Pacific for Development Initiative (D4D). The PacificMap is a platform for map-based access to spatial data from 22 Pacific Island Countries and Territories. It will lower the barrier and enhance access to timely, relevant and useful data for government and non-government organisations, businesses and communities throughout the Pacific.
The UN Biodiversity Lab is an online platform that allows policymakers and other partners to access global data layers, upload and manipulate their own datasets, and query multiple datasets to provide key information on the Aichi Biodiversity Targets and nature-based Sustainable Development Goals.
Open dataset of boundaries and regulations that apply to marine protected areas (MPAs) and fishery management areas in U.S. and international marine waters.
An open access geospatial data repository for the Pacific Region providing premier geophysical, geodetic, and marine spatial data sets. Developed through collaboration between the GeoScience, Energy and Maritime Division of the Pacific Community (SPC), University of Sydney, Geoscience Australia (GA), and GRID-Arendal.
The Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI) aims to provide the Pacific Island Countries (PICs) with disaster risk modeling and assessment tools. It also aims to engage in a dialogue with the PICs on integrated financial solutions for the reduction of their financial vulnerability to natural disasters and to climate change. The initiative is part of the broader agenda on disaster risk management and climate change adaptation in the Pacific region.
