This is a list of countries and territories by their average elevation above sea level based on the data published by Central Intelligence Agency, [1] unless another source is cited. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1 .
Sea level. This marker indicating sea level is situated between Jerusalem and the Dead Sea. Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth 's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datum – a standardised ...
The global average sea level has risen about 25 centimetres (9.8 in) since 1880. [1] Sea surface height change from 1992 to 2019: Blue regions are where sea level has gone down, and orange/red regions are where sea level has risen (the visualization is based on satellite data).
The highest and lowest points in China constitute the greatest elevation range within any single country at 9,002 metres (29,534 ft). The elevation ranges are also great in Nepal 8,789 metres (28,835 ft), Pakistan 8,611 metres (28,251 ft), and India 8,588 metres (28,176 ft). Monaco 's elevation range is among the greatest relative to surface ...
Sea levels have been comparatively stable over the past 6,500 years, ending with a 0.50 m sea level rise over the past 1,500 years. For example, about 10,200 years ago the last land bridge between mainland Europe and Great Britain was submerged, leaving behind a salt marsh. By 8000 years ago the marshes were drowned by the sea, leaving no trace ...
Established in 1985, The Global Sea Level Observing System ( GLOSS) is an Intergovernmental Oceanographic Commission (IOC) program whose purpose is to measure sea level globally for long-term climate change studies. The program's purpose has changed since the 2004 Indian Ocean earthquake and the program now collects real time measurements of ...
Wiki to create a free world map. OpenSeaMap is a software project collecting freely usable nautical information and geospatial data to create a worldwide nautical chart. This chart is available on the OpenSeaMap website, and can also be downloaded for use as an electronic chart for offline applications.
Hypsometry. Hypsometry (from Ancient Greek ὕψος (húpsos) 'height' and μέτρον (métron) 'measure') [1][2] is the measurement of the elevation and depth of features of Earth's surface relative to mean sea level. [3] On Earth, the elevations can take on either positive or negative (below sea level) values. The distribution is theorised ...
