‘VIHANGAM’ an Internet-based platform is associated with which field?

Static/current-affairs GK items that name a government or PSU digital initiative are resolved by identifying the launching organisation and the stated purpose of the platform — the sector is fixed by WHO deployed it and WHAT it does, not by the platform's name alone.

'VIHANGAM' is an internet-based portal integrated with a Remotely Piloted Aircraft System (RPAS/drone), inaugurated in September 2021 at Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India. It streams real-time aerial video from a Ground Control Station to authorised personnel over a secure, ID/password-gated web portal, and is used for drone-based volume measurement, environmental monitoring, and photogrammetric mapping at MCL's opencast mines (Bhubaneswari and Lingaraj, Talcher Coalfields, Odisha). Because both the deploying organisation (a coalfields company) and the stated use (monitoring mining operations) are mining-specific, the field associated with VIHANGAM is Mining.

• Excise: this field concerns duty on domestically manufactured goods such as alcohol and tobacco — VIHANGAM's documented function is aerial monitoring of mine sites, not duty assessment or goods manufacture.

• Broadcasting: this field concerns public transmission of radio/TV signals — VIHANGAM's video feed is a restricted, ID/password-gated link to a Ground Control Station, not a public broadcast.

• Taxation: this field concerns assessment and collection of levies on income or goods — nothing in VIHANGAM's drone-based aerial-survey function touches revenue assessment or levy collection.
