EPRI Transmission TTPLA Imagery
Aerial imagery of transmission towers and power lines with polygon (instance-segmentation) annotations, TTPLA-style.
- 1,242 images, 3,840 × 2,160 px.
- All annotations are polygons.
- 70 / 15 / 15 train / val / test split (seed 42).
Classes
| id | class | geometry | supercategory | is_line |
|---|---|---|---|---|
| 1 | cable | polygon | line | false |
| 2 | tower_lattice | polygon | structure | false |
| 3 | tower_tucohy | polygon | structure | false |
| 4 | tower_wooden | polygon | structure | false |
| 5 | void | polygon | ignore | false |
The mis-cased source label Cable was normalized to cable. void marks
ignore / occlusion regions.
Schema
Each row: image, image_id, file_name, width, height, and annotations
(columnar lists): id, category_id, category_name, supercategory,
segmentation (flat [x0,y0,x1,y1,...]), bbox ([x,y,w,h]), area, iscrowd,
is_line, subclass_id, subclass_name (TTPLA has no occlusion tag → 0 / none).
Merging with the H-frame dataset
Shares its schema with grantmwilkinson/epri-transmission-hframe.
Filter supercategory == "line" to select every wire across both datasets. Here cables
are filled polygons (is_line = false) — rasterize with cv2.fillPoly; the H-frame
wires are polyline centerlines (is_line = true, use cv2.polylines(..., thickness=k)).
Please consult the original TTPLA dataset terms before redistribution or commercial use.
