List of surveys in Gambia

from Wikipedia, the free encyclopedia
Map from the CIA World Factbook

This is a list of surveys in the Gambia .

The shape of the Gambia is determined by the Gambia River , which flows from east to west. The river landscape is surrounded on both banks by low laterite hills . 78 percent of the Gambia lies between sea level and 20  m above sea level . Around 400 of the 11,420 square kilometers are above 50  m above sea level and form a sandstone plain with rocky, bare hills.

The highest point is at least 53  m above sea level. A rating based on information from 1966 map of the US National Imagery and Mapping Agency listed in Jah Kunda on the northern border ( 13 ° 31 '  N , 14 ° 11'  W ) and in Nyamanari entirely in the east ( 13 ° 21 '  N , 13 ° 50 ′  W ), each directly on the border with Senegal , two points with an altitude of 174 feet, i.e. 53  m . The one at Nyamanari is also marked as the highest point in the country in The World Factbook . Both are within levels that are several square kilometers over 50 meters. On the basis of SRTM data , the peakbagger.com website calculated a highest point of 64  m between Sabi and the Senegalese Vélingara ( 13 ° 13 ′  N , 14 ° 10 ′  W ) on the edge of the Vélingara crater in 2019 . The highest elevation within a reddish sandstone plain, described by USGS and USAID , the page peakbagger.com and travel reports based on false Wikipedia information as 53  m high Red Rock does not exist according to research in the Wikipedia Commity.

The Gambia is the country in Africa with the lowest point. Worldwide only a few island states are even lower, see list of the highest points by country .

at least 53 m the highest point The Gambia reaches its greatest height on the border with Senegal without a defined hill rising from the sandstone plain
49 m Kassang Hill 13 ° 44 ′  N , 14 ° 55 ′  W. Near the Gassang Forest Park .
47 m Balangar Hill 13 ° 41 ′  N , 15 ° 22 ′  W. Near the Belel Forest Park .
47 m nameless 13 ° 18 ′  N , 14 ° 14 ′  W The name of the place Basse Santa Su means something like " compound above, on the hill " ( santo "[sic]" = above, su = compound) in the Mandinka language
38 m Hill at Mansa Konko 13 ° 28 ′  N , 15 ° 32 ′  W. At the foot of a hill is the capital of the Lower River Region , whose name means "King's Hill ".
37 m Konkoba Hill 13 ° 26 ′  N , 15 ° 49 ′  W. A flat, sweeping hill in the Lower River Region near Tendaba .
33 m Cape St. Mary cliff 13 ° 29 ′  N , 16 ° 42 ′  W. On the coast from Bakau to Fajara , the cliff rises more than 20 meters above sea level.
29 m Mamayungebi Hill 13 ° 31 '  N , 14 ° 35'  W Only a single hill with a name is shown on maps. The Gambia River loops around this hill in the Central River Region , the approximately 29  m high Mamayungebi Hill or Mamayungehi Hill .
28 m Bansang Hill (or: "Gamtel Hill" ) 13 ° 26 ′  N , 14 ° 39 ′  W. Hill near Bansang . The name "Gamtel Hill" probably comes from a cell phone transmitter of the Gambia Telecommunications Company (Gamtel).

The free database for geographic objects, GeoNames , is still called the Alligator Rock . The database refers to a point around 11  m above sea level on the bank of the Gambia River ( 13 ° 22 ′  N , 14 ° 23 ′  W ). It is not clear what kind of object this database entry (of the type "hill" ) describes, a report on a British geological survey from 1927 called "Alligator Rock" a gravel bank in the river.
