GlobWetland II Objectives

Contributes to the set up of a Global Wetlands Observing System (strategy 1.2 of the Ramsar Strategic Plan 2009-2015 adopted at the Conference of the Parties, COP 10 South Korea)

Facilitate the integration of remote sensing into the conservation and management of wetlands

Create standard and comparable geo-information products (principally based on EO technologies) about the status and trends in wetlands ecological character

The surface of Lake Burullus was reduced by over 20 % during this century due to large scale land reclamation for agriculture, aquaculture, housing and transportation. Therefore it was added to the Montreux Record, 4 July 1990

Excessive pumping of water from the oasis to large urban areas and illegal drilling for agriculture resulted into an environmental disaster in 1991

• The project consortium developed a GW-II toolbox on the basis of the User requirements

• The project consortium operated the GW-II toolbox (producing pilot products for 200 wetlands)

• The GW-II toolbox and the database is transferred to the hosting user organisations including training and capacity building

• The user organisations operate the GW-II Information System

Processing results based on the S2 simulation / Take 5 data Pre-processing • masking of clouds • Masking of pixels with values below 0 Water detection • Max. / Min water extend detection and water

surface calculation • Aquaculture detection • Water quality mapping (aquatic vegetation,

turbidity, … ) Agriculture detection • Irrigation mapping • Mapping of water consuming plants

Available data • Spot 4 and RapidEye time series with a 5-day revisit (from

February to June 2013) • Landsat-8 (from May 2013) • Burullus: 15 of 24 SPOT4, 11 of 23 RE usable • Azraq 21 of 25 SPOT 4 and 13 of 22 RE usable
