Your challenge: How can marine geospatial data be used to assess risk and mitigate coastal inundation?

For many people around the world, coastal inundation poses a significant threat. Caused by storm and tidal surges, coastal inundation can completely submerge surrounding areas in sea water - causing substantial damage to infrastructure and harm to vulnerable communities. 

This is an existing problem for many low-lying coastal states and, with sea levels continuing to rise, many more are likely to be affected in the coming years. In fact, if left unresolved, it is estimated that coastal inundation will affect 0.2–4.6% of global population annually in 2100, with expected annual losses of 0.3–9.3% of global GDP.  To mitigate the risk of coastal inundation, governments and disaster relief agencies need access to data that can help identify areas risk and how other factors (such as weather conditions) could further intensify the effects.  

At the UKHO, we hold a wealth of marine geospatial data that can help develop a better understanding of the coastal environment, with data sets including bathymetry, seabed geology, tidal data, weather information, as well as other worldwide open source data for earthquakes, monsoons and mangroves.

Your challenge is to develop a prototype of GIS solutions that shows how these data sets can support the prediction of coastal inundation by helping disaster relief agencies and other stakeholders identify vulnerable areas and mitigate risks, while minimising impacts on the environment and communities.

ADMIRALTY data


We hold a wealth of marine geospatial data from the seabed, to the coast, offshore and beyond. The following data sets (covering Anguilla) can be accessed to help you develop your solution.

Wind speed and direction

Historical data from 1979 to the present day. 

(File name: 'wind_era5_mean_xx.nc'. Described as metres per second.)

Precipitation

Historical data from 1979 to the present day.

(File name: 'precip_era5_mean_xx.nc'. Described as kilograms per m2 per second.)

Ocean waves and swell

Historical data from 1979 to the present day.

(File name: 'sea_and_swell_mean_xx.nc'. Described as metres.)

Bathymetry survey extents

​Polygons that show the extents of bathymetric surveys carried out (method of capture includes LIDAR) .

(To download the data, click within the polygon and a download link will appear along with other useful metadata.)

Satellite-derived coastline data set

The satellite-derived coastline data set has been created using a combination of free, open source satellite data and custom automated computer vision algorithms developed by the UKHO Data Science team. Includes the intertidal ranges.

​Depth contours

A line connecting points of equal water depth which is sometimes significantly displaced outside of soundings, symbols and other chart detail for clarity as well as generalisation. Depth contours, therefore, often represent an approximate location of the line of equal depth as related to the surveyed line delineated on the source. Also referred to as 'depth curve'. 

50m gridded bathymetry

​An interpolated .tif file displaying the depth data as a stylised raster. The result can be created from the .bag files in the 'bathymetry survey extents' layer.

Soundings data

A measured water depth or spot which has been reduced to a vertical datum (may be a drying height). 

Territorial sea area

​The territorial sea is a belt of water of a defined breadth but not exceeding 12 nautical miles measured seaward from the territorial sea baseline.

EEZ polygon

The Exclusive Economic Zone (EEZ) is an area, not exceeding 200 nautical miles from the baselines from which the breadth of the territorial sea is measured, subject to a specific legal regime established in the United Nations Convention on the Law of the Sea (UNCLOS) under which the coastal state has certain rights and jurisdiction.

​EEZ coastline

​A line representing the limits and boundaries of Anguilla's Exclusive Economic Zone (EEZ).

ENC coastline

​The coastline as defined by Electronic Navigational Charts (ENCs).

​Wrecks and obstructions

​Point features for the location of recorded wrecks and obstructions within Anguilla's Exclusive Economic Zone. 

​Obstructions point data


​Land area

​Polygons of the land areas belonging to Anguilla.

​Restrictive areas

​A specified area on land or water designated by an appropriate authority within which access or navigation is restricted in accordance with certain specified conditions.

​Seabed point features

​An area of the sea where the nature of bottom is homogenous. The nature of bottom includes the material of which it is composed and its physical characteristics. Also called 'character (or characteristics) of the bottom' or 'quality of the bottom'.

​Submarine cables

​An assembly of wires or fibres, or a wire rope or chain, which has been laid underwater or buried beneath the seabed.

​Cautionary areas

​Generally an area where the mariner has to be made aware of circumstances influencing the safety of navigation.

​Obstruction areas

​In marine navigation, anything that hinders or prevents movement; particularly anything that endangers or prevents passage of a vessel. The term is usually used to refer to an isolated danger to navigation.

​Anguilla Traffic Separation Scheme (TSS)

​A routeing measure aimed at the separation of opposing streams of traffic by appropriate means and by the establishment of traffic lanes.

AIS - not for download

​An automatic communication and identification system intended to improve the safety of navigation by assisting the efficient operation of Vessel Traffic Services (VTS), ship-to-ship and ship-to-shore operations, and ship reporting.
