Ordnance Survey (Welsh: Arolwg Ordnans), an executive agency and non-ministerial government department of the Government of the United Kingdom, is the national mapping agency for Great Britain, producing maps of Great Britain (and to an extent, the Isle of Man), and one of the world's largest producers of maps with a particular both historical and architectural form in the maps resulting from the conflict at both local and world level of the scales of maps known from the 19th Century as the 'Battle of the Scales'.

The name reflects its creation together with the original military purpose of the organisation (see ordnance and surveying) in the first instance in mapping Scotland at the time of the creation of the British United Kingdom following many centuries of conflict and confirmed later during the Napoleonic Wars when there was a threat of invasion from France, and its logo includes the War Department's broad arrow heraldic mark. Ordnance Survey mapping is usually classified as 'large scale' (i.e. showing more detail) or 'small scale'. Large-scale mapping comprises maps at six inches to the mile or more (1:10,560, superseded by 1:10,000 in the 1950s); it was available in sheet-map form till the 1980s, since when it has become digital. Small-scale mapping comprises maps at fewer than six inches to the mile and includes the "leisure maps", such as the popular one inch to the mile and its metric successors, still available in traditional sheet-map form. Ordnance Survey of Great Britain maps are in copyright for 50 years after publication date. Some of the Copyright Libraries hold complete or near-complete collections of pre-digital O.S. mapping.

"Choose the right" is a saying or motto among members of The Church of Jesus Christ of Latter-day Saints (LDS Church) that is taught to children and used by members of the church as a reminder to act righteously. The phrase is taken from an LDS hymn which has that title.

The letters CTR, a reference to this phrase, are incorporated into a shield logo designed by Helen Alldredge, a Primary General Board member in the 1960s. In 1970, a church committee headed by Naomi W. Randall recommended that the shield be incorporated into official church material. Since then, both the phrase and symbol have been used in religious educational materials for LDS youth of Primary age. The symbol is also used in LDS culture by members of all ages, both as a reminder of the motto, as well as an indicator of religious affiliation. The CTR initials, displayed on the shield and in other forms, can be seen mainly on CTR rings as well as other types of jewelry, tee shirts, bookmarks and stationery.

According to the US Patent and Trademark Office, the LDS Church's stylized "CTR" abbreviation and shield with the CTR symbol are trademarked for use on finger ring jewelry by Intellectual Reserve. The phrase "Choose the Right," however, is not trademarked in the United States and may be used by anyone for commercial purposes.^{[citation needed]}
