Create Satellite Imagery Tasking Schema #22

Open TJKoury opened 9 months ago

TJKoury commented 9 months ago

Overview

This issue delineates the creation of a Flatbuffer Interface Definition Language (IDL) schema tailored for orchestrating satellite imagery requests across a comprehensive array of providers. This schema aims to capture the diverse technical specifications, imaging capabilities, and tasking protocols inherent to each provider, ensuring a unified and efficient framework for satellite imagery acquisition and delivery.

Objectives

  1. Extensive Provider Integration: Develop an all-encompassing schema that integrates the wide-ranging imaging modalities, resolutions, and tasking capabilities of each provider, from the high-resolution optical and SAR imagery of Maxar and Airbus Intelligence to the unique hyperspectral and thermal imaging services offered by providers like Pixxel.

  2. Geospatial and Temporal Flexibility: Embed advanced geospatial targeting capabilities and temporal specifications within the schema to support detailed area selection, including support for AOIs (Areas of Interest) defined by coordinates, shapes, and lines, and temporal tasking options to capture imagery at specific dates and times.

  3. Imagery Specifications and Formats: Define a comprehensive set of specifications for image resolution, type (e.g., optical, SAR, multispectral, hyperspectral, thermal), and preferred data formats and compression standards, aligning with the operational capabilities and delivery mechanisms of each satellite imagery provider.

  4. Data Delivery and Processing Options: Specify data delivery preferences, including formats like GeoTIFF, JPEG, PNG, and data processing requirements such as atmospheric correction, image stitching, and mosaicking, tailored to the processing and delivery standards of each provider.

Deliverables

Timeline

The project will begin with a 10-week phase dedicated to in-depth research and schema design, focusing on the collection and analysis of detailed specifications from each satellite imagery provider. This will be followed by an 8-week development phase for schema construction and initial testing, culminating in a 4-week review and feedback period with stakeholders for final refinements.

Discussion

Engagement from satellite imagery specialists, data analysts, and industry stakeholders is crucial to this project's success. Input on provider-specific capabilities, technical challenges, and use case scenarios is highly encouraged to ensure the Flatbuffer IDL schema comprehensively serves the diverse needs of the global satellite imagery community.
