The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
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.

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 Allen Coral Atlas is a global-scale coral reef habitat mapping project that uses Planet Dove 3.7 m resolution daily satellite imagery (in combination with wave models and ecological data) to create consistent and high-detail global habitat maps to support reef-related science and conservation.
Global Benthic Habitat Maps characterize different coral reef bottom types. These bottom types include communities of living organisms attached to the reef (benthos), as well as sediments and underlying substrate.

This is an economic evaluation of the compensation to which Papua New Guinea’s customary landholders -
wrongly dispossessed through Special Agricultural Business Leases (SABL) - might be entitled if they successfully sued the government. The evaluation involves the calculation of commercial loss but also, and probably more importantly, economic equivalent value loss. The framework identifies the relevant heads of value (not just priced transactions) and demonstrates appropriate methods for valuation. It does not pretend to be a price calculator but rather a tool for advocacy.
Customary land registration processes can easily be captured by local ‘big men’ and companies with disastrous consequences for local people. This is the conclusion drawn in a study on recent oil palm expansion in Papua New Guinea by academic Caroline Hambloch from the University of London.
This paper analyses the perceptions of 120 landowner-households of Nanadai Clan of Gaire Village in Central Province and Sek Clan of Madang Province concerning breaking apart of communal ownership of customary land in PNG.
