John Purdy (hydrographer)
John Purdy (1773–1843) was an important English hydrographer. His work and influence extended beyond hydrography with the coinage of the term pharology, the study of modern lighthouses and their designs. Purdy's work ''Memoir, descriptive and explanatory, to accompany the New Chart of the Atlantic Ocean'' was adapted and improved; continuing to be released in its fifteenth edition fifty years after his death. Life The son of a bookseller at Norwich, Purdy took up the study of naval charts and similar subjects. Before 1812 he succeeded De la Rochette as hydrographer to Messrs. Laurie & Whittle, of 53 Fleet Street, London. Purdy does not seem to have taken part in hydrographic expeditions himself, and his work consisted in writing works and constructing charts based upon the reports of others; but eventually he became a leading authority of his time on hydrography. He was mainly instrumental in bringing ''Rennell's Current'' before the notice of navigators, and in 1832 James ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Of Cabotia
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring t ...

Pharology
Pharology is the scientific study of lighthouses and signal lights, their construction and illumination. The variation ''pharonology'' is occasionally attested. Those who study or are enthused by lighthouses are known as pharologists. Origin of term The term originally began as pharonology and is prevalent in many 1840s papers on the study of lighthouses. The term stems from the classical Latin or its ancient Greek etymon ''Pharos'', meaning lighthouse (Pharos was also the proper name of the famed lighthouse of Alexandria) and the Greek root “logos" (a word or discourse) in John Purdy's ''The Colombian Navigator; Or, Sailing Directory for the American Coasts and the West-Indies''. It was again used in Purdy's ''The New Sailing Directory for the Strait of Gibraltar and the Western Division of the Mediterranean Sea: Comprehending the Coasts of Spain, France, and Italy, from Cape Trafalgar to Cape Spartivento, the Balearic Isles, Corsica, Sardinia, Sicily and the Maltese Islands, ...

19th-century British Scientists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Purdy Islands (Landsat)
The Purdy Islands (or Mwilitau Islands) are an uninhabited island group in the Bismarck Sea, belonging to the people of M'Buke Island in Manus, Papua New Guinea. The Purdy Islands, Mole, Mouse, Rat, plus Bat and Alim (or North Bat and South Bat), form part of the Admiralty Islands group, in Manus Province. History The islands are owned by the Mbuke people. They were named after hydrographer John Purdy by his friend Captain Abraham Bristow on 16 February 1817. Bat Island was the site of RAAF radar station 340 RS between March 1944 and April 1944 during the Second World War. It was one of five such radar stations located within the Admiralty Islands to support the American Invasion. Bat Island proved to be a very dangerous location because it was infested with rats that carried mites which in turn carried Scrub typhus. The majority of the 30 or so strong unit succumbed to Scrub typhus and the station was abandoned after just over a month of service. A contingent of survivors a ...

Hydrographer
Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defense, scientific research, and environmental protection. History The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the private property, even closely held secrets, of individuals who used them for commercial or military advantage. As transoceanic trade and exploration increased, hydrographic surveys started to be carried out as an exercise in their own right, and the commissioning of surveys was increasingly done by governments and special hydrographic offices. National organizations, particularly navies, realized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander George Findlay
Alexander George Findlay (1812–1875) was an English geographer and hydrographer. His services to geography have been compared with those of Aaron Arrowsmith and August Heinrich Petermann. Life Findlay was born in London, 6 January 1812, a descendant of the Findlays of Arbroath, Forfarshire. His grandfather was a shipowner there, who moved his business to the River Thames. Findlay's father, Alexander Findlay was one of the original fellows of the Royal Geographical Society. The son Alexander George Findlay devoted himself to the compilation of geographical and hydrographical works. On the death of John Purdy, the hydrographer, in 1843, he took a leading position. In 1844 he was elected a fellow of the Royal Geographical Society, and was a member of its council and committees. His researches in meteorology attracted the attention of Robert FitzRoy. On the death of Richard Holland Laurie of Laurie & Whittle, the London geographical and print publisher, in 1858, Findlay took ...

A Map Of Cabotia (NYPL B20643844-5437645)
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...
