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.
Since 1972, the joint NASA/ U.S. Geological Survey Landsat series of Earth Observation satellites have continuously acquired images of the Earth’s land surface, providing uninterrupted data to help land managers and policymakers make informed decisions about natural resources and the environment.
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.

Normally, the baseline from which the territorial sea is measured is the low-water line along the coast as marked on large-scale charts officially recognized by the coastal state. This is either the low-water mark closest to the shore, or alternatively it may be an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide (like mud flats) is within 12 nautical miles (22 km; 14 mi) of permanently exposed land.
Nauru's Territorial Sea Baseline was defined using the 1993 topographic map produce by Survey Graphics Pty Ltd of Perth, Western Australia, under the direction of the Ministry of Island Development and Industry. The map is based on UTM Grid Zone 58, which is referred to the World Geodetic System 1972 (WGS 72). The WGS 72 coordinate system was then converted to WGS 84 using transformation parameters tabled on Nauru Maritime Boundaries Technical Report (TR 399).
The Maritime Zones Act 2013 states that the baseline of the territorial sea of Niue is measured from the low-water mark along the coast of Niue, or where there is a coral reef along any part of the coast of Niue, the low-water mark along the outer edge of the coral reef.
The territorial sea comprises those areas of the sea having, as their inner limits, the baseline and, as their outer limits, a line measured seaward from that baseline, every point of which is distant 12 nautical miles from the nearest point of the baseline.
The Marshall Islands Contiguous Zone was measured from the low water line of the seaward side of the normal baseline (coast), low-water line of the seaward side of the reef fringing the coast and bounding any lagoon waters adjacent to any part of that coast. MarZone delimitation software was used to generate the Contiguous zone using the World Geodetic System 1984 (WGS 84) reference datum as stipulated under the Republic of the Marshall Islands Maritime Zones Declaration Act 2016.
An exclusive economic zone extends from the baseline to a maximum of 200 nautical miles (370.4 km; 230.2 mi), thus it includes the contiguous zone.[3] A coastal nation has control of all economic resources within its exclusive economic zone, including fishing, mining, oil exploration, and any pollution of those resources.
The Maritime Zones Act 2013 states that the exclusive economic zone of Niue comprises those areas of the sea, seabed and subsoil that are beyond and adjacent to the territorial sea having as their outer limits a line measured seaward from the baseline, every point of which line is not more than 200 nautical miles from the nearest point of the baseline.
Niue's Territorial Sea Baseline was derived using the IKONOS satellite imagery taken in 2004 and Horizontal Datum used was the World Geodetic Datum 1984 (WGS 84) as stipulated under Section 12 of the Maritime Zones Act 2013.
The Maritime Zones Act 2013 states that the contiguous zone comprises those areas of the sea that are beyond and adjacent to the territorial sea, having as their outer limits a line measured seaward from the baseline, every point of which is distant 24 nautical miles from the nearest point of the baseline.
The Nauru Territorial Sea Zone was measured from the low water line of the seaward side of the normal baseline (coast) or the low-water line of the seaward side of the reef fringing the coast. MarZone delimitation software was used to generate territorial sea limit using the World Geodetic System 1984 (WGS 84) reference datum as stipulated under the Nauru Sea Boundaries Act 1997.
The combined Pacific EEZ layer are the layers gathered from gazetted datasets that the Pacific Community (SPC) has received from the project countries. In areas where there are no gazetted datasets provisional layers are being sourced from the Global Marine Regions database (https://www.marineregions.org/).
There are two layers available, he .shp file layer and the .kml layer which are being used by partners and member states in particular FFA for the Regional Fisheries Surveillance Center (RFSC).
