TranStar's Content Usage terms prohibit copying, distribution and external framing of its images without TxDOT's prior written permission. The opt-in text only said the pack was off unless CCTV_HOUSTON_ENABLED=1, without saying what an operator needs before setting it. Say "enable only if you hold TxDOT's written permission" in .env.example, the README, DATA_SOURCES.md, CURRENT-STATE and the changelog, matching the NYC and Florida packs, and fix the column of the .env.example comment. The houston-cctv credit now reads "(Houston, when enabled)" and links the Content Usage terms, like the Florida credit. Where the docs said frames are "never stored or redistributed", they now say what happens: frames are relayed on demand, buffered only per request, sent with no-store and not archived.

- Add Houston traffic cameras from Houston TranStar as a CCTV pack. The camera
|
|
list is one keyless JSON request to
|
|
`traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js`; frames are
|
|
stills synthesized from each numeric camera id on `www.houstontranstar.org`,
|
|
so a catalog field cannot steer the proxy off-host. Cameras without a
|
|
snapshot id, and cameras outside Greater Houston, are dropped. TranStar's
|
|
`dir` field (the side of the freeway the camera sits on) seeds a
|
|
low-confidence heading along the nearest lanes' travel direction. TranStar's
|
|
Content Usage terms (traffic.houstontranstar.org/disclaimer.aspx) prohibit
|
|
copying, distribution and external framing of its images without TxDOT's
|
|
written permission, so the pack is off by default; operators should set
|
|
`CCTV_HOUSTON_ENABLED=1` only if they hold that permission. Frames are
|
|
relayed on demand with `no-store` and not archived. Once enabled, it loads
|
|
the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and
|
|
Galveston; `CCTV_HOUSTON_MAX_SOURCES` changes that cap.
|
|
Snapshots update about every 3 minutes. The catalog-wide ceiling is
|
|
unchanged; extra cameras share it round-robin with the other packs
|
|
(mvanhorn, #1125).
