A nautical chart is a map specifically designed for use by maritime navigators. It includes information on the topography and hydrography of the seafloor, as well as navigational aids such as buoys and lighthouse locations.

The Network Advertising Initiative (NAI) is a US self-regulatory association for the digital advertising industry, founded in 2000. Member companies commit to a code of conduct covering how data is collected and used for advertising, and the NAI operates a consumer opt-out covering its members.
What the code covers
The NAI code sets expectations for transparency about what is collected, for obtaining consent where data is sensitive, for limits on retention, and for how precise location and health-related information may be used. Members submit to an annual compliance review.
Self-regulation, not law
This is the important distinction. The NAI is an industry body, not a regulator: its code binds members by agreement rather than by statute, and it carries no fining power. It sits alongside binding law such as the GDPR in Europe and state privacy legislation in the US, rather than replacing either.
Related bodies
The Digital Advertising Alliance (DAA) runs a parallel self-regulatory programme in the US, and the Interactive Advertising Bureau (IAB) develops the technical standards the industry builds on.

A northing is the north–south coordinate in a projected coordinate system — the distance northward from that projection’s origin, usually expressed in metres. It is paired with an easting, the east–west coordinate, and together they locate a point on a flat grid rather than on the curved surface of the Earth.
Measured from the projection’s origin, not always the equator
Northings are measured from whatever origin the projection defines, and that origin differs between systems. In UTM’s northern hemisphere zones the origin is the equator. In the southern hemisphere a false northing of 10,000,000 m is applied so values stay positive. In the British National Grid the origin sits southwest of the Scilly Isles, again chosen so no coordinate in Great Britain is negative.
This is why a northing is meaningless without knowing its coordinate reference system. The same number refers to entirely different places under different projections.
Northing and latitude are not the same thing
Latitude is an angular measure on a sphere or ellipsoid. A northing is a linear distance on a projected plane. Converting between them requires the projection parameters; they cannot be used interchangeably.
Where you meet them
Northings appear in surveying, cadastral and engineering data, national mapping products, and any GIS working in a projected rather than geographic coordinate system.
