Each feature has been assigned minimum and maximum longitude and latitude values by the Magellan project. These four values can be used to define a rectangular box in longitude-latitude space: each corner of the box is one of the four combinations of longitude and latitude. Such a box will generally exceed the limits of the feature. This file contains a row for each feature. Given in this row are four groups of coordinates, one for each corner of the box. The corners are expressed in three types of coordinates: (1) longitude and latitude, (2) image pixel coordinates defined in the cart:Cartography class, and (3) the tile/pixel coordinates that correspond to these image coordinates in the tiling scheme used to store the data.

This name uses only uppercase ASCII alphabetic characters and can be used for sorting and searching since it is unique within this table. When printing the name, the 'Diacritic Feature Name' should be used instead. Diacritic Feature Name 3 68 ASCII_String 40 The geographical feature name containing standard diacritical information. Contains upper and lower case letters. The name with the diacritical marks should be used when printing the feature name. DIACRITICALS USED IN THE TABLE The word diacritic comes from a Greek word meaning to separate. It refers to the accent marks employed to separate, or distinguish, one form of pronunciation of a vowel or consonant from another. This note is included to familiarize the user with the codes used to represent diacriticals found in the table, and the values usually associated with them. In the table, the code for a diacritical is preceded by a backslash and is followed, without a space, by the letter it is modifying. This note is organized as follows: the code is listed first, followed by the name of the accent mark, if applicable, a brief description of the appearance of the diacritical and a short narrative on its usage. \% acute accent; a straight diagonal line extending from upper right to lower left. The acute accent is used in most languages to lengthen a vowel; in some, such as Oscan, to denote an open vowel. The acute is also often used to indicate the stressed syllable; in some transcriptions it indicates a palatalized consonant. \: diaeresis or umlaut; two dots surmounting the letter. In Romance languages and English, the diaeresis is used to indicate that consecutive vowels do not form a diphthong (see below); in modern German and Scandinavian languages, it denotes palatalization of vowels. \^ circumflex; a chevron or inverted 'v' shape, with the apex at the top. Used most often in modern languages to indicate lengthening of a vowel. \~ tilde; a curving or waving line above the letter. The tilde is a form of circumflex. The tilde is used most often in Spanish to form a palatalized n as in the word 'ano', pronounced 'anyo'. It is also used occasionally to indicate nasalized vowels. \- macron; a straight line above the letter. The macron is used almost universally to lengthen a vowel. \u breve; a concave semicircle or 'u' shape surmounting the letter. Originally used in Greek, the breve indicates a short vowel. \o a small circle or 'o' above the letter. Frequently used in Scandinavian languages to indicate a broad 'o'. \ae diphthong or ligature; transcribed as two letters in contact with each other. The diphthong is a combination of vowels that are pronounced together. \, cedilla; a curved line surmounted by a vertical line, placed at the bottom of the letter. The cedilla is used in Spanish and French to denote a dental, or soft, 'c'. In the new Turkish transcription, 'c' cedilla has the value of English 'ch'. In Semitic languages, the cedilla under a consonant indicates that it is emphatic. \v check or inverted circumflex; a 'v' shape above the letter. This accent is used widely in Slavic languages to indicate a palatal articulation, like the consonant sounds in the English words chapter and shoe and the 'zh' sound in pleasure. \. a single dot above the letter. This diacritical denotes various things; in Lithuanian, it indicates a close long vowel. In Sanskrit, when used with 'n', it is a velar sound, as in the English 'sink'; in Irish orthography, it indicates a fricative consonant (see below). \' accent grave; a diagonal line (above the letter) extending from upper left to lower right. The grave accent is used in French, Spanish and Italian to denote open vowels. \_ fricative; a horizontal line through a consonant. A fricative consonant is characterized by a frictional rustling of the breath as it is emitted. Sources: Webster's New Collegiate Dictionary, G. and C. Merriam Co.
