1. Infrastructure for Assessing and Processing EO Data Sub-title: Observing and Data Receiving/Dissemination Systems Name: Halilu Ahmad Saba Professional title 15/06/2027, Sunyani

2. Nigeria Satellites 3 EO satellite
NigeriaSat1 decommissioned in 2011
NigeriaSat 2 still in Orbit with 2.5 (panchromatic, 5 (4 Bands) and 32m (4 Bands)
NigeriaSat-X 22m (Red, Green,Blue, Infrared)
NigeriaSat2 and NigeriaSatX are still in orbit and campaigning data

3. The Ground Receiving Station
This has a data storage system apart from capability to receive and download
It processes data from raw to the final stage
N2 & NX N1
7.2m Dish
Keystone and Smart-I software

4. N2 Data Product processing
L0 (Raw data)
L0R (Radiometric correction per channel of L0)
L1 -VHRI (Spectral channel combination of L0 leading to PAN sharpened colour)
L1-MRI (Spectral channel combination of L0 leading to composite colour picture)
L1R (Radiometric correction of combined channels)
L1G (Geometric systematic correction of L1 and L1R)
L1T ( Additional geometric correction of L1G using DEM and GCP)
L2A (L1G VHRI products Area scene processing)
L2S (L1G VHRI and MRI products Stereo scene processing

5. On-board Storage 4Bands 22mb each 1.2m KG sq. Low rate S-Band 8MBps.
2 x 2Gbyte data recorders

6. Practical Example with pixels
Over 2427 Tiles of 22.5 MB, = 54,607.5 mb or 54.6 GB
54.6 x 4 =218,430 MB or GB

7. Data Management and NGDI
Has Data Storage in TB that has never been filled
Working with Pink Matters in SA for automatic processing and flexible storage systems that will allow expansions in storage- Petabyte
NGDI storage running in TB
Small Disk firms within some departments

8. Advance Computation Laboratory
Cluster system
High level processors
Over 100 TB storage
Small Cluster system for Meteorological and EO processing simulations

9. Other Facilities for Processing and Storage
NASA ground station in NCRS with it storage in TB
The Servers across the country with GIS and Image processing software in our laboratories and some Universities especially the First Eight we collaborated with

10. Dissemination Bucket Approach- poor
FTP from Surrey Satellite Technology – poor
Pink Matter Console – before the end of 2017
