Remote Sensing Workflow: Land Cover Classification Example
This paper examines a real-world remote sensing workflow using Planet Labs' land cover classification project as a case study. It traces each phase of the workflow — from project scoping and satellite data acquisition through radiometric and geometric preprocessing, feature extraction, supervised classification, and accuracy assessment — and evaluates how closely this commercial workflow aligns with standard academic frameworks for remote sensing analysis. The paper highlights the role of confusion matrices in validating results and emphasizes the importance of transparent reporting for reproducibility. The discussion draws on Planet Labs' Dove satellite constellation and peer-reviewed literature on remote sensing image segmentation.

What makes this paper effective
- Uses a concrete commercial example (Planet Labs) to ground abstract remote sensing concepts in a real-world workflow, making the discussion accessible and applied.
- Follows a logical, step-by-step structure that mirrors the actual workflow sequence, helping readers understand how each phase connects to the next.
- Closes with an explicit comparison to an academic framework, demonstrating critical evaluation rather than simple description.
Key academic technique demonstrated
The paper demonstrates applied case analysis — anchoring a technical process description to a named, real-world example and then evaluating that example against an established academic or instructional framework. This technique shows the writer can move between concrete practice and conceptual principles, a core skill in applied science writing.
Structure breakdown
The paper opens by introducing Planet Labs as the case study, then walks through each workflow phase in sequence: project scoping, data acquisition, preprocessing, feature extraction, classification, analysis, and reporting. A final section explicitly maps the commercial workflow to an academic framework, functioning as both synthesis and evaluation. The reference list includes one peer-reviewed journal article and one industry source, reflecting the paper's blend of academic and applied content.
Introduction
A practical example of a remote sensing workflow is a land cover classification project executed by the commercial entity Planet Labs. Planet Labs uses high-resolution satellite imagery to monitor and classify land cover changes globally. The workflow begins with project scoping, where objectives such as tracking deforestation or urban expansion are defined. The next step is data acquisition, which involves the collection of high-resolution imagery from Planet's fleet of Dove satellites, enabling frequent revisits to capture temporal changes (Planet, 2024).
Data Acquisition and Preprocessing
Data preprocessing follows data acquisition, involving radiometric and geometric corrections to standardize images and remove distortions. This step includes atmospheric correction to eliminate atmospheric interference. The images are then assembled into a mosaic to provide seamless coverage of the study area. The feature extraction phase uses advanced algorithms for spectral enhancement, followed by supervised classification methods in which known land cover types are identified using ground truth data (Planet, 2024).
