EFG MT3.1 Artificial shores – current maps

MT3. Anthropogenic shorelines biome

Published

June 7, 2024

This page provides information about the valid indicative distribution map for the ecosystem functional group MT3.1 Artificial shorelines. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: MT3.1.web.map v1.0.

Marine ecoregions (Spalding et al. 2008) containing major and minor occurrences of urbanized shorelines were identified from the map of night lights (see T7.4), imagery available on Google Earth and expertise of authors. Occurrences were aggregated to 1 degree spatial resolution and intersected with the coastline to exclude areas inland and in the open ocean.

Datasets

MEOW-2008 (Spalding MD et al. 2008):

How to use the data

Available files

Following maps are considered current and valid indicative distribution maps for this ecosystem functional group. Web navigation maps are optimised for use in webapps, but they have similar methods and differ only in details of format and processing.
