DFO Flood Event 4548

Albania: Maximum Observed Flooding

Layers, bottom to top: Light gray is all previously-mapped flooding. Dark Reddish Brown is flooding mapped by Copernicus. Red is flooding mapped by DFO from Copernicus Sentinel 1 data provided by the European Space Agency. Blue is a reference normal water extent. Urban areas (satellite-visible lights) are shown in dark gray.

Explanation

Event Numbers:

The Flood Observatory maintains a Global Active Archive of large flood events, 1985 to present. New major flood events are entered into this archive each week. A hand-drawn GIS polygon for each event outlines the estimated total area affected.

Event Maps:

In some cases, severe or damaging floods become the focus of Observatory flood extent mapping. As part of collaborations with other organizations, and the Global Flood Partnership, the Observatory's maps and other data are made available here to the public. With attribution, they can be used for non-commercial purposes. With permission, they can be used for commercial purposes. Consult the Creative Commons license shown below and contact Robert.Brakenridge or Albert.Kettner (at Colorado.edu) if questions. Geotif versions and GIS files are also provided.

This event is selected for Observatory production of map and GIS data products.This web page and associated image and map (GIS) files are the permanent Flood Observatory record of this event. As the flood event proceeds, additional flood extent layers and maps may be added. The objective is mapping of the maximum extent flooded.

Brief Event Description:

According to Flood List: "Almost 5,000 households have suffered flood damage in Albania since torrential rainfall on 01 December, 2017. Around 600 families are still homeless after being forced to evacuate. Over 100 road sections and dozens of bridges have been damaged, along with infrastructure such as power and water supply stations. In the latest assessment, an area of around 15,000 hectares was under water. Flooded areas of Albania. Photo: NATO EU Civil Protection Mechanism (EUCPM) was activated on 05 December after receiving a request from Albania . Priority requested items are bridge reconstruction elements, power generators, water motor pumps, water safety and rescue garments and other relief item. The Directorate-General for European Civil Protection and Humanitarian Aid Operation (ECHO) has produced a map of the affected areas in Albania."

In some cases, Copernicus Emergency Mapping Service GIS data derived from various satellite sources may be incorporated into DFO map displays and also provided in the event data directories. Please visit the Copernicus Emergency Management Service for information as to the satellites, mapping methods, and any usage restrictions. Some data may be translated into MapInfo GIS formats (available in the GISData directory) for purposes of integration with DFO-generated flood mapping results. See also citation recommendations for use of Copernicus-sourced information.

Image Data Sources:

NASA Landsat 8 and Copernicus/ESA Sentinel SAR data if used in this map were obtained from the the U.S. Geological Survey Hazards Data Distribution System. and the Sentinels Science Data hub, respectively. Landsat 8 is jointly managed by NASA and the United States Geological Survey. Copernicus is supported by the European Commission..

MODIS data processing

Click here for access to an automated daily MODIS-derived .shp file GIS record (record commences in 2011). Choose appropriate 10 deg x 10 deg map sheet directory and appropriate dates; longitude and latitudes refer to upper left map sheet corner. Not all floods are mappable at the MODIS spatial resolution of 250 m. Some DFO event maps also include these automated MODIS data. If provided in the GIS file directories, the relevant MODIS "Current" file used is renamed to show the date used. These files are an accumulation of all MODIS water for that date and 13 days prior. The data shown on the maximum flood extent maps also refer to the MODIS date range; other satellite image dates are within that date range.

Obtain the GIS Data:

Flood extent files (Shp or Mapinfo) supporting this Flood Event Map are located here.

These files may include high spatial resolution mapping such as from Sentinel or Landsat, or lower resolution files from MODIS. File names commonly include the sensor source (e.g., S1 for Sentinel 1, LS8 for Landsat, MODIS for MODIS) and the image date.

Data from the Global Surface Water Explorer is included as part of the light gray previous mapped maximum surface water extent. It is based on Landsat images at a spatial resolution of 30 m (Jean-Francois Pekel, Andrew Cottam, Noel Gorelick, Alan S. Belward, High-resolution mapping of global surface water and its long-term changes. Nature 540, 418-422, 2016). The NASA Shuttle Water Boundary Data (SWBD) surface water extent (90 m resolution), blue, was derived from NASA's the 11-day February, 2000, SRTM mission and this "permanent" water layer was also corrected using Landsat data. These data are not provided in the GIS directories.

When used in the maps, NASA NRT Global Flood Mapping maximum water extent for the years 2013-2015, at 250 m spatial resolution, provide part of the (light gray) previous satellite-mapped water extent layer. DFO creates these annual water extent layers from data provided by that project, by accumulating into one annual file all of the daily .shp files for each year. DFO has also produced flood extent files through mapping of individual floods (~ yr 2000 to present); these are also included in this layer.

When used in the maps, Copernicus Emergency Management Service data are imported as GIS files and installed in the GIS data folder.
