to{'en': 'The Global Lakes and Wetlands Database (GLWD) version 2 provides a comprehensive and seamless global map of inland surface waters distinguished into 33 waterbody and wetland types. GLWD v2 was developed by harmonizing the best available ground- and satellite-based data sources and has been designed to represent the maximum non-overlapping extents of aquatic ecosystems over the broad contemporary period of 1990-2020.\r\n\r\nGLWD v2 represents a total of 18.2 million km2 of wetlands at a grid cell resolution of 15 arc-seconds (approximately 500 m at the equator). The data consist of a map of the dominant waterbody or wetland type in each grid cell, as well as 33 individual class layers which represent the sub-cell fraction of each specific class within each grid cell.\r\n\r\nVersion 2 of GLWD (Lehner et al., 2025) is the successor of the widely-used GLWD version 1 (Lehner & Döll, 2004). The quality, resolution, and format of GLWD v2 significantly improves upon GLWD v1 and supersedes the older version.', 'es': '', 'fr': ''}

| 195 | provides a comprehensive and seamless global map of inland surface | ||||
| 196 | waters distinguished into 33 waterbody and wetland types. GLWD v2 was | ||||
| 197 | developed by harmonizing the best available ground- and | ||||
| 198 | satellite-based data sources and has been designed to represent the | ||||
| 199 | maximum non-overlapping extents of aquatic ecosystems over the broad | ||||
| 200 | contemporary period of 1990-2020.\r\n\r\nGLWD v2 represents a total of | ||||
| 201 | 18.2 million km2 of wetlands at a grid cell resolution of 15 | ||||
| 202 | arc-seconds (approximately 500 m at the equator). The data consist of | ||||
| 203 | a map of the dominant waterbody or wetland type in each grid cell, as | ||||
| 204 | well as 33 individual class layers which represent the sub-cell | ||||
| 205 | fraction of each specific class within each grid cell.\r\n\r\nVersion | ||||
| 206 | 2 of GLWD (Lehner et al., 2025) is the successor of the widely-used | ||||
| 207 | GLWD version 1 (Lehner & D\u00f6ll, 2004). The quality, resolution, | ||||
| 208 | and format of GLWD v2 significantly improves upon GLWD v1 and | ||||
| 209 | supersedes the older version.", | ||||
