BMTF study sample data: modeling and independent evaluation point sets (2025, 10-day steps)

This dataset contains two point-sample tables used in the BMTF study: 1. modeling_set.csv (n=100), used for model fitting workflows.2. evaluation_set.csv (n=100), used for independent validation. Each record includes a coded class label (class_key), sample source (source), geographic coordinates (lon, lat; WGS84), a 10-day temporal step identifier (step_name), and split role (split_role). Temporal coverage is represented by 10-day steps from 2025-04-01 to 2025-11-30. Detailed schema, distributions, and quality checks are documented in README.md within this data package.
