SEO Report to WGISS • Brian KilloughCEOS Systems Engineering Office (SEO) • WGISS-46 Meeting • October 22, 2018
COVE Tool Summary • The CEOS Visualization Environment (COVE) is a browser-based suite of tools for searching, analyzing, and visualizing actual and potential satellite sensor coverage. • COVE is FREE and OPEN for anyone to use! There is a large international user base with 4000+ users in 2017. • COVE includes 131 missionsand is linked to several mission archives to get metadata and browse images for past acquired data: Landsat-5/7/8, Sentinel-1, Sentinel-2, and CBERS-4. • Coverage Analyzer and Data Browser: New tools for coverage assessments and scene data to support data ordering. www.ceos-cove.org
Coverage Analyzer • Support for Landsat 5/7/8, Sentinel-1A/1B, Sentinel-2A and CBERS-4. • Output using discretizations for Landsat WRS, Sentinel-2 tiles, and various Lat-Lon degrees (0.10, 0.25, 0.5, 1.0). • Example Case:Ispra, Italy, August 3, 2018Sentinel-2A, MSI Instrument- COVE query results - Table with scene info- Browse image
Data Browser • Support for Landsat 5/7/8, Sentinel-1A/1B, Sentinel-2A, and CBERS-4 ... similar to Coverage Analyzer • Filtering for cloud cover threshold (optical missions) • Example Case:Italy, August 2018Sentinel-2A, <50% cloudy- Table Output with scene information and browse images- Links to view the acquisition details, zoom into footprint on the map, and order the scene
Status and Future Plans • The team has made a number of updates to the core COVE tool to improve security and enhance operating performance. Some of these changes have caused issues with a few features that will be resolved in the coming months. • Links to archive databases are a constant issue, as things change on the data provider side. Current issues with S1 archive at ASF to be resolved in 6-8 weeks. Other issues with SPOT, Pleaides, Radarsat-2, ALOS, TerraSAR-X and ResourceSAT-2 will be resolved in the coming months. • Adding a custom mission capability to support future mission concept studies • Adding coverage and revisit performance calculation capabilities • Adding cloud cover overlays derived from Landsat historical metadata (13 in total, 1 raw average, 12 monthly average files) • Adding coincident calculations for both future predictions and historical archive data
Open Data Cube News • New Africa Regional Data Cube deployed in May 2018 for 5 countries. • Attended SatSummit in Washington on Sept 19-21. The world is interested in Data Cubes, ARD, COG formats and cloud computing. • Continuing to expand our supply of Jupyter notebooks for data cube applications. • Strong desire to use ”indexed” cloud-based satellite data with data cubes. • Working on an ODC architecture framework and development of a Jupyter Hub ODC “Sandbox”
49 countries in 20 months 9 6 34 Operational Under Development Under Review or Expressed Interest Operational: Australia, Colombia, Switzerland, Taiwan, Kenya, Tanzania, Ghana, Sierra Leone, Senegal
WGISS-SEO Collaborations • Working with Lolanda Maggio (ESA) to develop an approach for an Open Source Software Inventory (database). The NASA team is investigating options. (CEOS Action FDA-10) • Maintain and expand the connections from satellite mission archives to the COVE tool. • Investigate approaches for taking advantage of USGS data hosted in the AWS cloud. Once in place, we could use help developing scripts that pre-process the data and build cubes for download.
