pmlrsg/lake-polygons-PML: Lake polygons accompanying Calimnos v1.4.0 and Lakes_cci Climate Research Data Package v2.0

  • 1. Plymouth Marine Laboratory
  • 2. University of Reading


This release includes polygons of 4264 waterbodies used with Calimnos v1.4. This data set is used to delineate waterbodies in the Copernicus Land Monitoring Service (Lake Water products) and the European Space Agency Lakes_cci project (Lake Water-Leaving Reflectance). The polygons are created in Well-Known-Text format, based on the ESA Land Cover CCI project Maximum Water Extent raster v4. The polygons have been manually corrected to not include upstream or downstream rivers or dams, but do not systematically exclude islands within the maximum water extent. Polygons used in the Lakes_cci (around 2000 out of 4264) have further been harmonized with the Lake Surface Water Temperature land/water mask, based on the same source.

Identifiers used in this dataset refer to definitions from four sources, by the first four characters used for the filename: GLWD - numbering corresponds to the Global Lakes and Wetlands Database HYLA - numbering corresponds to the Hydrolakes database GLBL - lake definition was (re)defined as part of the NERC GloboLakes project CGL2 - lake definition was (re)defined as part of the Copernicus Land Monitoring Service

Metadata files in csv format are included with this release for the lakes included in the Copernicus Land Monitoring Service (cglops) and Lakes cci projects.
