  • GMES & Africa and Copernicus Marine Earth Observation

    This is the online phase for the GMES&Africa and Copernicus Marine Earth Observation Training Course. 

    This training is co-organised by the MarCoSouth GMES&Africa consortia and EUMETSAT in collaboration with other GMES&Africa partners and guest lecturers.

    The MarCOSouth project aims to maintain, further develop and provide a sustainable platform for local, institutional, human and technical capabilities in the African countries  through the development of services focused on sustainable socio-economic development, empowering a wide range of users in the public and private sectors through the application of regionally-optimised satellite observations and model based forecasts in African marine and coastal domains.

    Through Global Monitoring for Environment and Security (GMES) and Africa, the Africa Marine and Coastal Operations projects will contribute to the implementation of the African Space Policy and Strategy (ASPS) through application of world-leading satellite sensors, e.g. the European Sentinel series, with innovative and regionally optimised products. Examples of ASPS objectives addressed are: developing indigenous infrastructure and capabilities that service an African market; provisioning regionally appropriate services and products; ensuring all levels of government are able to access data through a centralised portal.

    The goal of this workshop is to strengthen your capacities to develop Earth Observation products, services and tools that promote sustainable management of marine resources, improve marine governance, and stimulate the growth of the blue economy in Africa..The online phase will introduce you to the Copernicus Marine Data Stream (CMDS), providing you with the background knowledge of the Copernicus programme, satellites and instrumentation, data access and formats, tools and software, necessary to begin working with this data for marine applications .The aims of this training course (both the online and classroom phases) are to help you:

    • Understand the concepts around Earth Observation across the value chain;
    • Learn the underlying principals of marine remote sensing, how to access / download data and products, and how to work with various open source tools; 
    • Develop and deliver a 'mini project' so you are able to gain all the skills that are directly applicable to your research / work needs.
    This online phase will be followed by a classroom phase in Zanzibar, Tanzania from the 12th - 20th November (applications are closed).

     

Software and tools for working with marine satellite data

  • Software and tools for working with marine satellite data

    Working with marine satellite data often involves using large numbers of (often) individually large data files, of varying formats. The applications for this data are also broad, and range from exploratory, research led purposes, to routine and operational analysis for more commercial applications. As such, there are many different tools available to work with marine satellite data. Here we provide a (non-exhaustive) list and discussion of some of the more commonly used tools by the marine remote sensing community. Choosing which tool to use will be very dependent on the type of application you are working on. Key things you should consider include:

    • Do you know explicitly what you want to do with the data? Or do you want to explore and investigate?

    • Do you need to repeat your application regularly?

    • Do you need to be able to share the processes you go through with others? If so, what is their experience?

    Below you can complete some basic tutorials using software developed specifically to work with the sort of data available from the Sentinel-1, 2 and 3 satellites. 

    You can also read about other types of software available, the programming languages commonly used across the remote sensing community, and discuss the advantages and disadvantages of these.

    To complete this section you should read all content, install Acolite, install SNAP and complete the tutorials with the data you downloaded in the previous section, install python and/or post about your choice of programming language. 

     

    • Software designed for processing Sentinel-2 data for ocean applications. Please install this for use during the classroom phase. 

    • Please make a new discussion post below to confirm you have installed this piece of software. If you have had problems, please post details of these, and we will assist you. 

    • Visualizar

      This guide will help you install the SNAP software for working with OLCI and SLSTR data.

    • Visualizar

      This tutorial will give you a basic overview of using the SNAP software to work with Sentinel-3 data from the OLCI and SLSTR instruments (we will cover altimetry data and SRAL using Python, but you can also look in to the BRAT software should you wish). This is by no means an exhaustive tutorial. We encourage you to explore the software during the online phase of the course, and there will be further time to discuss SNAP in more detail during the classroom phase. You can ask questions/share useful tools you are working with in the discussion forum attached to this part of the course. We would also recommend signing up to the STEP user forum, where you can find much more information about SNAP and ask questions to both other users and the developers of the software. Further tutorials on some SNAP functionalities are available here.

      Please make a new discussion post below to confirm you have installed this piece of software. If you have had problems, please post details of these, and we will assist you. 

    • Discussion about the different programming languages used within the marine remote sensing community, and their advantages and disadvantages.

    • This book will guide you through the installation process for Python, as well as give you some ideas for the sorts of ways Python can be used to work with Sentinel-3 data and beyond.

      You may choose to not install Python if you wish to work in a different language during the classroom phase of this training. However, we will only be providing example scripts in Python.

      We would recommend installing the anaconda distribution of python 3.7, as this is the version we have used to develop training material. Please note the additional packages that need to be installed.

    • Please make a new discussion post below to confirm you have installed python/or that you would like to use a different language independently (let us know which!) during the classroom phase of this training. If you have had problems, please post details of these, and we will assist you.
