YOLinO TTPLA Benchmark (512×512)
TTPLA aerial imagery prepared for CAPSTONE / YOLinO polyline training and evaluation.
Each sample is a 512×512 PNG tile with matching NumPy (.npy) polyline labels.

ttpla-transmission-1536
Structure-only, 1536px detection tiles derived from grantmwilkinson/epri-transmission-ttpla, schema-compatible with
grantmwilkinson/epri-transmission-structure-1536.
Classes: transmission_structure (id 2) only.
Tiling: regular overlapping grid, native 1536px, no padding, empty tiles dropped, tight per-tile bboxes.
Split inherited per source image (TTPLA 70/15/15, seed 42). cable and void dropped; is_line always False.
