Background The signing of the Spot Image Data Reception and Distribution Agreement between the CSIR’s Satellite Application Centre (SAC) and SPOT Image in 2006 Funded by the Department of Science and Technology. It has continued under the auspices of the South African National Space Agency (SANSA) with the signing of a new Spot Data Direct Receiving Station Supply, Reception and Distribution (DRS) Agreement between SANSA and Airbus Defence and Space Systems in November 2013. The success of the annual SPOT 5 National Mosaic relies heavily on this data acquisition agreement 8th National SPOT Mosaic Disseminated to over 40 government departments (national, provincial, and local government). The imagery provided is utilised by all spheres of government for addressing a number of societal benefit areas, such as: agriculture, biodiversity, conservation, forestry, geology, land cover change, and regional planning, to name but a few.

National Stakeholders Government Departments Implementing DST’s mandate Data provision to government departments (Single license, multi-user arrangement) Value-added data products and services In-service personnel training

2013 SPOT 5 National Coverage Acquired between 2013/01/10 and 2013/12/31 Three scenes patched with 2014 coverage

2013 SPOT 5 National Coverage Two locations with missing coverage (minor) Missing SPOT 5 paths and rows. 121/401 140/400 140/401

2013 SPOT 5 Level 3 (ortho-bundled) Packaging Widest very high spatial resolution annual coverage of RSA since 2006 National coverage consists of 1932 ortho-bundled images 644 panchromatic images 644 multispectral images 644 pan-sharpened images Projection - WGS84 Transverse Mercator Documentation SPOT1-7 End User License Agreement Packaging Imagery Compressed Geotiff (zipped) to save space Metadata Shape files such as Index which contains acquisition metadata

2013 SPOT 5 Mosaic Packaging

2013 SPOT 5 Mosaic Packaging National coverage consists of 548 RGB image tiles Mosaicked and delivered as quarter degree tiles (1:50,000 tiles of RSA) Projection - WGS84 Transverse Mercator Seamless mosaic of pansharpened SPOT 5 imagery True colour unlike level 3 imagery (artificial or pseudo blue band) Documentation SPOT1-7 End User License Agreement Packaging Imagery Compressed Geotiff (zipped) to save space or JPEG 2000 Metadata Shape files such as quarter degree tiles

2013 SPOT 5 Mosaic Packaging Finding your area of interest using: Number of tiles: 548 Spatial resolution: 2.5 m. Spectral resolution: RGB natural colour Geographic Coordinate System: GCS WGS 1984. Datum: D WGS 1984. Prime Meridian: Greenwich. Angular Unit: Degree. File format: JPEG2000 or Geotiff Finding your area of interest using: the web map application packaged with the mosaic data

SPOT 5 Level 3 vs Mosaic imagery 1:1 1:1 Ideal for: Remote sensing applications. e.g. NDVI Ideal for: Cartographic applications. e.g. Digitising

2013 SPOT 6 & 7 National Coverage 2014 SPOT 5 national coverage will be the last SPOT 5 decommissioning, 2015 quarter 1 SPOT 6 replaces SPOT 5 national coverage Plans are currently underway to create the SPOT 6 National Mosaic Comparisons between SPOT 5 and SPOT 6/ 7 Specification SPOT 5 SPOT 6 & 7 Number of satellites 1 2 (180º apart) Spatial resolution 2.5 m pan 10 m colour 1.5 m pan 6 m colour Mission plans per day 6

Better agility means better acquisition SPOT 5 SPOT 6 & 7 Spot 6 & 7 pitch angle capacity allows to acquire targets on the same area Image source: Airbus Defence & Space

Better agility means better acquisition Latitude conflict no longer an issue! 6 mission plans per day means SPOT 6 & 7 have better weather forecasting. Less cloud cover! Image source: Airbus Defence & Space

SPOT 6 & 7 Benefits Seasonal mosaics vs annual mosaics Faster, clearer acquisitions The most available high spatial resolution annual coverage of South Africa! Image source: Airbus Defence & Space

2013 SPOT 6 ortho-bundled Packaging 1062 scenes 531 panchromatic (1.5 m) 531 multispectral (6 m) Pansharpened scenes not included 1.5 m pansharpened scenes will be delivered in 2013 SPOT 6 Mosaic Packaging Projection: WGS84 Transverse Mercator Format: Geotiff 2013 SPOT 6 Index shapefile

Economic Value of SPOT Mosaic The cost of the imagery required for the Mosaic, based on Airbus Defence and Space Systems listed price of EUR 4.6/km2 for SPOT 6 imagery, would be in the region of R192 142 3681 per annum for a single user. Through the DRS Agreement, SANSA spends in the region of R35 000 000 per annum for access and distribution rights to various government entities from the entire fleet of SPOT satellites

Economic Value… Notwithstanding the fact that not all governments would require a full national mosaic, the cost saving of the current single-license multi-user arrangement is clearly evident. As indicated previously, current distribution statistics indicate 40 National and Provincial government departments depend on the SPOT National Mosaic for fulfilling their mandates Through an extensive survey that SANSA Earth Observation conducted in 2013, various National government departments indicated that SPOT imagery contributes substantially to their ability to fulfil their mandates (e.g. disaster management, human settlements, crop monitoring, etc. Presentations from Stakeholders will demonstrate the full value derived from SPOT imagery
