Relevancy of statements in maps, charts and plans
A statement in a trusted map, chart or plan — one published for public sale or made under Government authority — is itself a relevant fact, as to the matters such maps usually show.
How to read Section 30
Trusted map + usual content = a relevant fact.
Maps or charts published for public sale, or maps or plans made under Central/State Government authority.
Only the matters usually represented in such maps — rivers, roads, boundaries — not stray notes.
Such a statement is itself a relevant fact — no need to prove it through the mapmaker.
The bare Act
The section in its own words — colour-keyed by what each phrase does.
Statements of facts in issue or relevant facts, made in published maps or charts generally offered for public sale, or in maps or plans made under the authority of the Central Government or any State Government, as to matters usually represented or stated in such maps, charts or plans, are themselves relevant facts.
In short: a map that the public can buy, or that a Government made, carries a built-in reliability — so what it usually shows (a coastline, a river, a boundary) is evidence on its own. The section does not bless a private sketch, or an unusual note the map would not normally carry.
→ This carries forward IEA 1872 § 36 — the map-and-chart companion to the public-record rule in § 29.
Glossary
A graphic representation of geography or layout — a chart is typically for the sea/air, a plan for a defined site.
Commercially published and sold to the public — the market check on its accuracy.
Made by or under the Central or a State Government — e.g. Survey of India.
The things a map of that kind normally shows — only these are made relevant.
The statement stands as evidence without calling the mapmaker to prove it.
The national mapping agency — a classic example of a Government-authority map under this section.
The picture
Two trusted sources, one map → a relevant fact.

Connected provisions
Public records under duty
§ 29 trusts official records; § 30 trusts published and Government maps — the same reliability logic.
Right or custom
Maps often settle boundaries, public ways and customs — the very matters § 11 makes relevant.
IEA 1872, § 36
Carried forward — statements in trusted maps, charts and plans are relevant facts.
