MAPEO-water: in the cloud processing for drone water applications (13 Nov 2023, 2 pm – 5 pm)

USF Student Center, Regetta Room, 1st Floor, 200 6th Ave S, St. Petersburg, FL 33701

Today drones are used in various applications, from infrastructure to mining and agriculture. Drones and lightweight cameras can be readily found on the market at low cost and can be easily operated without very specialized training. The collection of data above water and the retrieval of information on the water quality has lagged behind because of the higher complexity in data processing. The water case has some specific challenges that need to be tackled. For instance, water bodies often look dark on images resulting in a much lower signal-to-noise ratio compared to land applications. The water column is also a dynamic environment subjected to e.g. current or tide resulting in a rapidly changing scene under investigation.

Attendees will learn how to account for these challenges, the importance of flight protocols and important steps in the drone data processing workflow toward meaningful, quantitative information, like suspended sediments or chlorophyll concentrations of the upper water layers. You will be introduced to the MAPEO-water platform, a processing workflow in the cloud (AWS) for aerial drone images. MAPEO-water supports drone data upload towards the cloud environment with additional metadata, performs first quality checks on the raw data before the data processing starts. End products can be accessed through webservices. The outputs are georeferenced images with corrected quantitative values representative for the water column. This allows derivation of information such as, but not limited to, turbidity or chlorophyll concentrations.

The tutorial includes hands-on exercise where the attendees can work with raw and processed drone images and derive information on the water quality.

Objectives. Objectives of the tutorial are to learn:

• about the challenges and issues when acquiring drone images above water
• how to deal with these challenges from data acquisition towards data processing
• about the MAPEO-water platform

Requirements. A laptop with the following system requirements:

• Windows, Linux or MacOS
• QGIS installed
• Java installed, with minimally 1 GB (preferably 2 GB) of RAM.
  • Java version 11 or higher (17 LTS is recommended).
  • Go directly to https://adoptium.net to install the latest compatible Java version.
  • See section 10 Appendix A: Java/JDK setup (Windows), or section 11 Appendix B: Java/JDK setup (MacOS), for more information.
  • Allow internet access for Java – on first run some firewall/internal policies block access or present a pop up when launching Java for the first time, you must allow internet access for Java!

HyperCP: a best practice community processor for above-water radiometry (13 Nov 2023, 2 pm – 5 pm)

USF Student Center, Ballroom 1, 200 6th Ave S, St. Petersburg, FL 33701

HyperCP (HyperInSPACE Community Processor) is a toolkit designed to provide automated processing of above-water, hyperspectral ocean color radiometry data using state-of-the-art methods and protocols for quality assurance, uncertainty estimation/propagation, sky/sunglint correction, convolution to satellite wavebands, and ocean color product retrieval. This short course, designed for advanced-to-expert level attendees, will focus on teaching how to operate HyperCP. Data outputs are formatted to text files for submission to the NASA SeaBASS and OCDB and saved as comprehensive HDF5 records (Hierarchical Data Format version 5) with automated processing reports. The package is designed to facilitate rigorous, flexible, and transparent data processing for the ocean color remote sensing community. Radiometry processed in HyperCP are used for water optical characterization, ocean color product retrieval algorithm development, and orbital platform validation.

Currently, HyperCP supports Sea-Bird Scientific HyperSAS packages with and without SolarTracker or pySAS platforms and hand-held TriOS Ocean Colour Radiometers.  HyperCP is an open science, open-source Collaboration (involving NASA, EUMETSAT, the FRM4SOC-2 Project, the University of Victoria and University of Maine). HyperCP stems from NASA’s HyperInSPACE, initially designed to adhere to the best practices detailed in the legacy NASA Ocean Optics Protocols (Mueller et al., 2003) and to incorporate the advances defined in the IOCCG Optical Radiometry Protocols (Zibordi et al., 2019). In addition, HyperCP also allows incorporation of advances proposed by other partners of the HyperCP team, such as those proposed by the FRM4SOC-2 team, University of Maine, etc.

Course outcomes. At the end of the course, participants will become familiar with 

1. the best practices to acquire above-water remote-sensing reflectance measurements, 
2. the necessary processing steps to obtain remote-sensing reflectance from radiometric raw data, 
3. the uncertainty sources underlying remote-sensing reflectance obtained from above-water measurements, 
4. the use of HyperCP to process such measurements (TriOS and SeaBird OCRs), 
5. how to acquire and configure the HyperCP toolkit, 
6. (optionally) how to implement HyperCP using built-for-purpose test and own datasets of raw measurements, and 
7. (optionally) the utility of the toolkit in the context of their own workflows.

Target audience. All attendees are welcome, however, the course is predominantly aimed at:

• established and early career ocean colour researchers
• operational oceanographers performing (or intending to perform) in situ above-water radiometry measurements
• private and public sector specialists engaged in marine monitoring activities

Requirements. A laptop is required for this training (e.g. Linux/MacOS/Windows, core i5, 16 GB RAM).

There are no prerequisites for this course, but to assure the execution of HyperCP during the course you are highly recommended to perform the following in advance:

• clone HyperCP git repository in advance into your local environment from NASA’s Github shared space.
• create the corresponding conda environment following the instructions in the readme file.
• (optional) run a first blind test of the code, following the readme. 

We look forward to seeing you at the course!
