Map viewer
GloFAS map viewer is a web-mapping platform which provides easy access to the flood forecasts and
observations
of the Global Flood Awareness System (GloFAS). The products are tailored to give a fast overview of the
hydro-meteorological situation, both ongoing and upcoming hydrological events at global scale as well as
background maps.
The map viewer is designed to be an intuitive interface where a number of different products, also called
‘layers’, can be displayed on their own or overlaid on top of each other. The layers are organized in five
categories, and each associated with a short description:
-
Meteorological: summarising precipitation forecasts over the first 10-day period of
the forecast horizon in GloFAS
-
Hydrological: encompassing both the latest GloFAS foreseen floods together with their
impacts on populations and GloFAS Seasonal forecasts
-
NRT flood mapping: the seamless, global-scale, SAR-based estimate of flooded areas
provided by the GFM
-
Static: showing background information such as inundation plains, or lakes and
reservoirs
-
External WMS: where users can import new layers produced externally and available
through the WMS standard
Each layer can be ordered or switched on and off, and the date of the displayed dataset can be selected
using the date tool. By default, GloFAS map viewer is set to the current date. Note that the earliest data
available
is for the pre-operational GloFAS system, 1st January 2011.
Detailed descriptions of the products available on the GloFAS-IS mapviewer can be found on the dedicated
wiki pages.
