EFG SF2.1 Water pipes and canals – current maps

SF2. Anthropogenic subterranean freshwaters biome

Published

This page provides information about the valid indicative distribution map for the ecosystem functional group SF2.1 Water pipes and subterranean canals. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: SF2.1.web.orig v1.0.

Freshwater ecoregions (Abell et al. 2008) containing urban and industrialised areas with water transfer infrastructure were identified by consulting available ecoregion descriptions (http://www.feow.org/), maps of irrigation and other water infrastructure, and expertise of authors. Due to uncertainty and limited verification and likely limited spatial extent within mapped areas, all inferred occurrences were shown as minor at 30 arc seconds spatial resolution.

Datasets

FEOW-2008 (Abell et al. 2008):

Source of biogeographical range. Resolution: variable (polygons), static. Accuracy evaluation: qualitative (experts judgement).

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.

  • Web navigation (code: SF2.1.web.orig, version v1.0)
  • Indicative Map (code: SF2.1.IM.orig, version v1.0)
