About the Client
The client operates in the geospatial analytics and remote sensing sector, using satellite imagery and AI-driven segmentation models to analyze agricultural landscapes. Their solutions support crop monitoring, land-use classification, and environmental assessment, where precise spatial annotations are essential for reliable model training and actionable insights.
Challenges They Faced
To train high-performing segmentation models, the client required highly accurate and consistent annotations across complex agricultural terrains. However, several data quality and workflow challenges impacted model reliability:
- Over-Clumping of Adjacent Fields – Annotators often grouped neighboring fields and landscape elements together, reducing the granularity needed for field-level analysis.
- Ground vs. Overhead Class Confusion – Inconsistent interpretation of ground features versus overhead elements led to classification errors and reduced dataset integrity.
- Inconsistent Boundary Precision – Variations in edge accuracy affected critical classes such as farm fields, tree crops, woodlands, water bodies, and single trees.
- Annotation Conflicts at Label Intersections – Lack of clear rules for overlapping classes created conflicts, particularly where overhead features intersected ground classes.
- Low-Quality Image Segments – Portions of imagery with poor clarity required structured exclusion, but inconsistent handling led to noisy training data.
- Time Constraints on Large Annotations – Tight time limits for complex images resulted in incomplete annotations and loss of effort, impacting productivity and dataset completeness.
