List of surveys in Gambia
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 .
list
height |
Surname | coordinate | comment |
---|---|---|---|
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.
