1 Contribution to the Implementation of the African Space Programme: EO Data and Infrastructure *9.a) space segment - available observations (space & in-situ data) and observational gaps & *9.b) ground infrastructure – data access, archive, processing and dissemination Dr. Tendani Lavhengwa Data Systems Manager South African National Space Agency AfriGEOSS Symposium 2016_04_29 Victoria Falls

2 1 st Overview… Available Observations Our data and systems Systems Overview Multiple observation sources Available observations SANSA's growth in capacity Dissemination for societal benefit Types of deliveries Benefits and opportunities Accessing our data

3 Our data and systems ground receiving station HBK, Tshwane data systems hosts large archives

4 Systems Overview TS5 DRS ACS Tapes Lustre environment Internal FTP – DMZ Website - Catalogue Interaction with service providers External Data extractions Migration Maintenance Other ad-hoc activities Current operations

5 Multiple observation sources *Direct Reception at ground receiving station (Demodulators) *Downloads from sources, eg. USGS *Data discs *Other sources

6 Available observations **Current reception –Landsat 7 –Landsat 8 –Spot 6 & 7 –Modis (TERRA and AQUA) –NPP –CBERS-04 -P5 –CBERS-04 -P10 –CBERS-04 -MUX –CBERS-04 -WFI

7 Available observations **Large historic archive –Landsat5 –Spot1 –Spot2 –Spot4 –Spot5 –CBERS-02B –SumbandilaSAT –MISR **Planned: A mirror site for: Sentinel

8 SANSA's growth in capacity Over 200TB of sensor data Over 50% additional capacity since 2015 Challenges to consider –Over other platforms –the need to share changes as they happen –to keep community updated

9 Dissemination for societal benefit to over 40 government departments –local government, –provincial, –national, –research institutions, and –universities other requestors –private –& more

10 Types of deliveries & supported interactions Types of deliveries -raw data -processed data (multiple levels) -national products value added products -other products and services custom developed SANSA Website updates (Content, Image of the week and Articles) Online catalogue Atlas Fundisa Portal FTP updates Other internally developed systems, scripts and automation

11 Benefits and opportunities SPOT 6 & 7 –single-license multi-user arrangement for SPOT data CBERS4 –free data, following an installation in October 2015 SPOT –Heritage Program participation MODIS –Terra and Aqua data

12 Accessing our data Online Catalogue - http://catalogue.sansa.org.za/http://catalogue.sansa.org.za/

13 2 nd Overview… Ground Infrastructure Gaps in understanding challenges / realities Use of freely available datasets CBERS-4 detour Collaborations & partnerships with other institutions Discoverability of data Strategy: Development of regional level infrastructure access points and discoverability Strategy: EO architecture revision Finally, some thoughts...

14 *** Gaps in understanding challenges / realities the costs associated with spatial data management move away from data selling to sharing proactive, storage procurement delays consider lead times, 6 - 8 months for production capacity continual proactive increase in capacity need to continue availability of historic archive the costs associated with spatial data management move away from data selling to sharing proactive, storage procurement delays consider lead times, 6 - 8 months for production capacity continual proactive increase in capacity need to continue availability of historic archive *** Use of freely available datasets to increase archives for data products and comparisons Datasets options –Spot Heritage Program, SANSA is participating –Sentinel data opportunities –the case of CBERS-4 Data, to follow… to increase archives for data products and comparisons Datasets options –Spot Heritage Program, SANSA is participating –Sentinel data opportunities –the case of CBERS-4 Data, to follow…

15 *** CBERS-4 detour China Brazil Earth Resource Satellite (CBERS) Centre for Research Data Application (CRESDA) SANSA previously received CBERS- 02, still available on archive CBERS-04 was launched on 7 December, 2014 The installation is a contribution to GEO activities China Brazil Earth Resource Satellite (CBERS) Centre for Research Data Application (CRESDA) SANSA previously received CBERS- 02, still available on archive CBERS-04 was launched on 7 December, 2014 The installation is a contribution to GEO activities Some history Source: Introduction to cresda, CRESDA installation team, October 2015

16 *** CBERS-4 detour Installation –from 29th Sept 2015 to 15th Oct 2015 On-Site Installation & Acceptance Test, –completed on 15-October-2015 On-Site Acceptance Satellite Data Processing System, –completed on 15-October-2015 Satellite Data Capacities: Raw data &Processed to level-02 An average of 2 passes per day Installation –from 29th Sept 2015 to 15th Oct 2015 On-Site Installation & Acceptance Test, –completed on 15-October-2015 On-Site Acceptance Satellite Data Processing System, –completed on 15-October-2015 Satellite Data Capacities: Raw data &Processed to level-02 An average of 2 passes per day Installation and capabilities

22 *** Collaborations & partnerships with other institutions Start with national, regional, continental then global SANSA working with High Performance Computing (HPC): –processing –data storage –delivery Collaborates with: –DIRISA, responsible for data intensive research in SA –SAEON, for data discovery and link to GEO Start with national, regional, continental then global SANSA working with High Performance Computing (HPC): –processing –data storage –delivery Collaborates with: –DIRISA, responsible for data intensive research in SA –SAEON, for data discovery and link to GEO MESA, SANSA to provide data UK Space Agency & others MESA, SANSA to provide data UK Space Agency & others *** Multiple MoU’s

23 *** Strategy: Development of regional level infrastructure access points for data –access –archive –processing & –dissemination for data –access –archive –processing & –dissemination *** & Strategy: Discoverability linking and sharing of portals sharing meta data linking catalogues referrals to other data sources

24 *** Strategy: EO architecture revision address special challenges for EO data centres architecture in line with user requirements delivery of data to the end user processing of data and availing products instead of RAW *only deliver products to clients priority options: –infrastructure management/maintenance vs. –data administration vs. –software development vs. –outsourcing vs. –other? address special challenges for EO data centres architecture in line with user requirements delivery of data to the end user processing of data and availing products instead of RAW *only deliver products to clients priority options: –infrastructure management/maintenance vs. –data administration vs. –software development vs. –outsourcing vs. –other? solutions get to production faster costs are reduction operational efficiency increased solutions get to production faster costs are reduction operational efficiency increased ***matters of hyperconvergence ***additional matters virtualisation, must be part of the solution direct link between user needs and data infrastructure assist users in achieving closer access to data sources clearly linking data acquisitions to specific thematic areas virtualisation, must be part of the solution direct link between user needs and data infrastructure assist users in achieving closer access to data sources clearly linking data acquisitions to specific thematic areas

25 *** & Finally… engage in activities to establish suitability from new technologies (cloud, big data, high availability) we need to SHARE ICT EO data and infrastructure approaches across Africa The AfriGEOSS Data & Infrastructure Coordination Team (DICT) needs to work closer & implement co-ordinated projects. As a unit we can then approach projects such as the SKA engage in activities to establish suitability from new technologies (cloud, big data, high availability) we need to SHARE ICT EO data and infrastructure approaches across Africa The AfriGEOSS Data & Infrastructure Coordination Team (DICT) needs to work closer & implement co-ordinated projects. As a unit we can then approach projects such as the SKA with CBERS-4 being a product of GEO activities… can this data be broadcasted on GEONETCAST? with CBERS-4 being a product of GEO activities… can this data be broadcasted on GEONETCAST? The BIG question…
