Spot 5 Take 5 ESA UNCLASSIFIED – For Official Use Frank Martin Seifert EO Science and Applications Division ESA Earth Observation Programmes GFOI/GOFC-GOLD Expert WS | 1 October 2014 | Wageningen

Background Spot-5 will deorbit in Q2/Q CNES has proposed to repeat the Take5 R&D activity with the Spot 5 satellite. The first 'Spot4/Take5' was done in early 2013 and consisted in lowering the Spot-4 satellite to put it in a 5- days repeat mode, similar to Sentinel-2A/B. ESA decided to support a 'Spot5/Take5’ experiment in 2015 within the mandate of the Earthnet Third Party Mission Program (TBC by PBEO) A feasibility study for sites needs to be done before year end by CNES, in order to prepare the orbit change end of Q1/2015 ESA UNCLASSIFIED – For Official Use

Simulated Sentinel-2 Time Series (in partnership with Take 5 initiative of CNES/CESBIO) 14 ESA sites, globally distributed with international partners Multi-sensor & multi-temporal data set (February-June 2013) Forest Marine Agriculture Wetlands

Forestry: Multi-temporal Methods Multi-temporal experiment will look specifically on methods to: 1.Reduce effects of clouds and cloud shadows by multi- temporal pixel mosaicking in cloud persistent areas 2.Provide early warning of deforestation and detection of forest degradation based on frequent change detection 290 km 10 meters resolution RapidEye over Congo

Combined SPOT 4 & RE Coverage 98% of the area covered by 3 images or more Gabon test site

Experiment benefits cover a larger part of the vegetation period in the Northern hemisphere (1. April to 31. August with Spot-4 it was January to June 2013 assuming a 5-day revisit over 5 months, thus resulting images per site have an improved data quality, with a variety of modes wrt Spot4/Take5 (10m, likely 5m TBC, 2.5m excluded) have a much higher number of sites that could be acquired, however a conflict-free plan has to be agreed based on a mission study executed with CNES before year’s end; The main restriction for the number of sites are the production cost for each product in addition to the funding of the experiment ESA UNCLASSIFIED – For Official Use

Next Steps Prepare a list: name, coordinate or kml/shape, number of spot products required to cover once, purpose, in-situ data, application relevant for multi-temporal? – at the end of this workshop (3 Oct)  Priority for processing: 1 = top priority, 2 = backup, 3 = you might have funds for processing ESA / CNES will contact international partners like other space agencies and international initiatives e.g. GFOI, GEOGLAM, JECAM ESA UNCLASSIFIED – For Official Use
