Show me the schema of the transmission lines dataset.

Show me the schema of the wildlife lands dataset.

Find transmission lines that intersect wildlife lands.

How many wildlife areas intersect transmission lines?

Which transmission lines have the greatest number of wildlife intersections?

SELECT
    t.*,
    w.*
FROM transmission_lines t
JOIN wildlife_lands w
    ON ST_Intersects(t.geom, w.geom);

Transmission lines intersecting wildlife lands

| Transmission Line | Wildlife Area | Intersection |
|-------------------|---------------|--------------|
| Line A             | Area 001      | Yes          |
| Line B             | Area 014      | Yes          |
| Line C             | Area 021      | Yes          |

Total intersecting transmission lines: 3
