Metres above mean sea level (MAMSL) or simply metres above sea level (MASL or m a.s.l.) is a standard metric measurement in metres of vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level might differ from the actual elevation of a given location over sea level at a given moment.
Metres above sea level is the standard measurement of the elevation or altitude of:
The elevation or altitude in metres above sea level of a location, object, or point can be determined in a number of ways. The most common include:
Accurate measurement of historical mean sea levels is complex. Land mass subsidence (as occurs naturally in some islands) can give the appearance of rising sea levels. Conversely, markings on land masses that are uplifted due to geological processes can suggest a lowering of mean sea level.
Feet above sea level is the most common analogue for metres above sea level in the US customary measurement system, abbreviated FAMSL.

Fraser Pass is a mountain pass in British Columbia's Rockies. Its summit is 2,015 metres above sea level. Although immediately adjacent to the Continental Divide, the pass does not cross it; rather, it bridges the drainage basins of the Fraser River and Columbia River, both Pacific-draining rivers.The pass is drained to the north by the Fraser River. A dripping spring just west of a pond at Fraser Pass is the source of British Columbia's longest river. The south side of the pass is drained by Hugh Allan Creek; it flows into Canoe Reach, the north arm of Kinbasket Lake which is the reservoir behind Mica Dam on the Columbia River. Fraser Pass is difficult to reach. Access by foot requires about 40 km (25 mi) of bush-whacking from the Yellowhead Highway near Lucerne Campground. The most feasible access is by a 25-minute helicopter flight from Valemount. Beautiful British Columbia Magazine first identified the source of the Fraser River during an expedition to Fraser Pass in 1985. Group tours by helicopter to the source of the Fraser are offered every few years by Wells Gray Tours.Gummer's How
Gummer's How is a hill in the southern part of the Lake District, on the eastern shore of Windermere, near its southern end. How, derived from the Old Norse word haugr, is a common local term for a hill or mound.
Although a relatively small hill (321 metres above sea level) by the standards of the Lake District, it is the highest of the foothills in the area, and commands excellent views, particularly along Windermere (the summit looks out over the magnificent Town Head House estate towards the lake), but also across to the Coniston fells and the central fells, as well as the broad panorama of Morecambe Bay. There is an OS trig point on the summit.
The walk to the summit is usually from the road at Astley's Plantation car park, itself at over 200 metres above sea level, and only 700 metres from the summit. Although short and easy by most standards, and popular with families, it has many of the characteristics of a walk in the higher Lakeland fells, with some (short) steep slopes, rocks to negotiate, and rowan, bracken and heather. The lower slopes are forested, but the upper portion is moorland.Gummer's How is the subject of a chapter of Wainwright's book The Outlying Fells of Lakeland. He describes it as "an old man's mountain", and says of it: "And when ancient legs can no longer climb it know ye that the sad day has come to hung up the boots for ever and take to slippers".Simon Jenkins rates the Windermere panorama of the Lake District, Pennines and Morecambe Bay as one of the top ten in England.Haddersfield, Jamaica

The island spans the area between the Margaret Bridge (south) and the Árpád Bridge (north). Before the 14th century the island was called Insula leporum (Island of Rabbits). Administratively Margaret Island used to belong to the 13th district, but now is directly under the control of the city.
Its appearance today was developed through the connection of three separate islands, the Festő (Painter), the Fürdő (Bath) and the Nyulak (Rabbits), during the end of the 19th century, to control the flow of the Danube. Originally, the island was 102.5 metres above sea level, but now has been built up to 104.85 metres above sea level to control flooding.Matala, Angola
