The Randolph Glacier Inventory (RGI) is a global set of glacier outlines intended as a snapshot of the world’s glaciers outside of ice sheets. It provides a single outline for each glacier from approximately the year 2000, as well as a set of attributes and other relevant auxiliary information. Glacier outlines are distributed as Shapefiles. Hypsometric data and attributes (CSV files) and metadata (json) are also available. All RGI data are packaged both globally and by region (as defined by the Global Terrestrial Network for Glaciers (GTN-G) Glacier Regions). The RGI is not suitable for measuring glacier-by-glacier rates of area change. However, it can be used to estimate glacier volumes; rates of elevation change at regional and global scales; and glacier responses to climatic forcing. RGI version 7.0 was developed by the “Working Group on the Randolph Glacier Inventory (RGI) and its role in future glacier monitoring” of the International Association of Cryospheric Sciences (IACS). The glaciological community contributes glacier mapping data to the Global Land Ice Measurements from Space (GLIMS) database. A subset of the glacier outlines in GLIMS are then extracted and reprocessed to produce the RGI. See the RGI documentation under "User Guide" (below) for more information.

El visor de SIDS proporciona información relacionada con las aguas subterráneas en los Pequeños Estados Insulares en Desarrollo. En la actualidad, el sistema contiene principalmente información derivada del Programa de Evaluación de Aguas Transfronterizas (TWAP) sobre 43 SIDS. Los datos incluyen indicadores que describen las dimensiones hidrogeológicas, ambientales, socioeconómicas y de gobernanza de los sistemas de aguas subterráneas de los SIDS.

Los datos han sido obtenidos a partir de encuestas por cuestionario y un exhaustivo estudio documental realizado por la Universidad Simon Fraser (Canadá) y coordinado por UNESCO-IHP. La información en el sistema puede ser explorada y analizada mediante un visor basado en mapas, lo que resulta particularmente útil para realizar análisis comparativos entre múltiples SIDS. Además, también están disponibles fichas informativas de los SIDS que proporcionan resúmenes claros por cada SIDS. Se recopilarán y cargarán más datos sobre los SIDS en el visor a medida que estén disponibles.

Para cualquier consulta o comentario sobre los datos e información de los SIDS, por favor visite nuestra página del Área Focal de SIDS. (https://www.un-igrac.org/areas-expertise/small-island-developing-states-sids)

The Reference Observatory of Basins for INternational hydrological climate change detection (ROBIN) project established a new long-term collaboration of international experts to establish and sustain a global reference hydrological network (RHN), through common standards, protocols, indicators, and data infrastructure. ‘Reference Hydrometric Networks’ (RHNs), consist of gauging stations whose catchments are relatively undisturbed and record high quality data and little missing data. The concept of RHNs, their history and evolution are described in (Whitfield et al., 2012) previously and many countries have already established RHNs, however this is the first initiative to bring them together at a global level. The ROBIN Full Dataset consists of 3,060 stations in 30 countries, however the dataset described here is the ROBIN Public Dataset which contains metadata records for all 3,060 stations and daily streamflow data for a total of 2,386 stations. This tiered approached was due to data sharing restrictions in some countries. More information about the ROBIN Network and dataset can be found on the project website: https://www.ceh.ac.uk/our-science/projects/robin

Estos mapas, desarrollados por Deltares, representan el impacto de los peligros de inundación previstos en los distritos de Chimanimani y Chipinge, en Zimbabue, y han sido evaluados con una resolución de 30 metros.
