Agenda:  Burgeoning Role of Python for Earth Observation Data Analysis

  1. Syed Rizvi (Open Data Cube) discusses the use of recently developed Open Data Cube Jupyter notebooks for a water classification application that allowed developers to parse their code into blocks which can be run independently of each other, with variables stored in the background, saving vast amounts of time.
  2. Rich Signell (USGS) discusses how Jupyter Notebooks have been used by the US IOOS (Integrated Ocean Observing System) to do manual skill assessment of over 20 forecast models for over 1000 sensors by building standards-based Python code that uses catalog search, standard web data service access, custom skill metric calculation and interactive display of results.  
  3. Alber Sanchez (INPE)  discusses how Python is used in a web service that reduces the gap between data and analysis for EO scientists.  He will present how to retrieve time series of vegetation indexes of the Amazon forest, and how to filter these data.  

Presentations:

  1. Open Data Cube Jupyter Notebooks
  2. Automating Model Skill Assessment with Python
  3. Python Used in a Web Service

Topic: Data Cubes for Large Scale Data Analytics
Date: Monday, June 19, 2017.

Watch the recorded webinar!

Description:  Recent work by WGISS members has been fleshing out the concept of Data Cubes to enable analysis of large Earth Observation data sets.  Please join us as Rob Woodcock of CSIRO (Australia) and Brian Killough of the CEOS System Engineering Office provide an introduction to Data Cubes.  Rob will set the stage for Data Cubes with user needs, key features and basic high-level architecture, followed by Brian to talk about some more of the inner workings of Data Cubes.

Watch the recorded webinar.

As CEOS Earth Observations grow in both quantity and variety, users face increasing challenges in finding the most appropriate data for their use.  Ranking data search results by their expected relevance for the user is potentially one of the most powerful ways to help users quickly zero in on the best data for their purpose. This webinar will look at some of the techniques being used within Earth Observation data search tools, followed by a discussion of possible future directions in relevancy ranking.

Agenda:

  1. Introduction to the topic – 10 minutes – Chris Lynnes
  2. Search Relevancy in EOSDIS – 10 minutes – James Norton
  3. Search Relevancy in GEO Data Access Broker –  10 minutes – Stefano Nativi
  4. Looking forward in Search Relevancy – 10 minutes – Chris Lynnes & Stefano Nativi
  5. Questions/Discussion
