This map shows different wetland types, as well as lakes and rivers, across North America. The map was made using the Global Lakes and Wetlands Database (GLWD), which was created using a variety of the best available sources for lakes and wetlands on a global scale.
This map shows different wetland types, as well as lakes and rivers, across North America.
The map was made using the Global Lakes and Wetlands Database (GLWD) Level 3, which was created using a variety of the best available sources for lakes and wetlands on a global scale.
Level 3 of the Global Lakes and Wetlands Database (GLWD) comprises lakes, reservoirs, rivers, and different wetland types in the form of a global raster map at 30-sec resolution. GLWD-3 may serve as an estimate of wetland extents for global hydrology and climatology models, or to identify large-scale wetland distributions and important wetland complexes.

Este mapa muestra diversas clases de humedales, además de lagos y ríos, de América del Norte. El mapa se elaboró usando la Base de Datos Mundial de Lagos y Humedales (Global Lakes and Wetlands Database, GLWD), creada a partir de una variedad de las mejores fuentes disponibles con datos sobre lagos y humedales en escala mundial.

Cette carte montre les différents types de terres humides, ainsi que les lacs et les cours d’eau de l’ensemble de l’Amérique du Nord. On l’a créée en utilisant la Global Lakes and Wetlands Database (GLWD), constituée à partir de certaines des sources de données les plus fiables au monde à propos des lacs et des terres humides.

The Commission for Environmental Cooperation (CEC) is an international organization created by Canada, Mexico, and the United States of America under the North American Agreement on Environmental Cooperation (NAAEC), which came into force at the same time as the North American Free Trade Agreement (NAFTA). The CEC was established to address regional environmental concerns, help prevent potential trade and environmental conflicts, and to promote the effective enforcement of environmental law. As of 2020, the CEC operates in accordance with the Environmental Cooperation Agreement, which entered into force at the same time as the CUSMA/T-MEC/USMCA trade agreement. This data set is available in several formats, including Shapefile, Map package, and a PDF Map, along with other files appropriate to particular format, such as .lyrx and .qlr files.

The dataset was compiled from various data sources, mostly dating from the 1970s to 1990s. While no explicit data lineage is provided, the dataset is widely used and cited in scientific literature. GLWD-3 is suitable for global-scale modeling and analysis, with a resolution of 30 arc-seconds. The data are considered reliable for identifying general wetland distributions but may not reflect fine-scale or recent wetland changes.
The GLWD-3 dataset was developed by Bernhard Lehner (World Wildlife Fund US) in collaboration with Petra Döll (University of Kassel) as part of the Global Lakes and Wetlands Database project. It integrates various datasets compiled from the 1970s to 1990s to generate a global raster layer at 30 arc-second resolution, representing lakes, reservoirs, rivers, and wetland types. The methodology and validation process are documented in Lehner & Döll (2004), Journal of Hydrology, Vol. 296, pp. 1–22.
