David Rumsey Map Collection
The David Rumsey Historical Map Collection is a large private map collection with over 150,000 maps and cartographic items. The collection was created by David Rumsey who, after making his fortune in real estate, focused initially on collecting 18th- and 19th century maps of North and South America, as this era "saw the rise of modern cartography." After 2004 Rumsey expanded the collection to include maps from the 16th though 21st centuries, covering more of the world. In 2008 the collections's website was cited as one of only seven websites with freely available "skillfully compiled carto-bibliographic entries with corresponding early-map images."Joel Kovarsky (2008), "Carto-Bibliography on the Web: Links Combinging Text and Image", ''Imago Mundi'', vol. 60, no.1, pp. 93–96. . At that time the site comprised 16,000 digital images. In February 2009, David Rumsey announced that the entire collection would be donated to Stanford University, including 150,000 maps and their digit ...

Historical Geographic Information Systems
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Map Collections
A map is a symbolic depiction emphasizing relationships between elements of some space, such as Physical body, 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 (language use), context or Scale (map), 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'. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joan Blaeu
Joan Blaeu (; 23 September 1596 – 21 December 1673) was a Dutch cartographer born in Alkmaar, the son of cartographer Willem Blaeu. Life In 1620, Blaeu became a doctor of law but he joined the work of his father. In 1635, they published the ''Atlas Novus'' (full title: ''Theatrum orbis terrarum, sive, Atlas novus'') in two volumes. Joan and his brother Cornelius took over the studio after their father died in 1638. Blaeu became the official cartographer of the Dutch East India Company like his father before him. Blaeu died in Amsterdam on 21 December 1673. He is buried in the Westerkerk there. Maps Blaeu's world map, ''Nova et Accuratissima Terrarum Orbis Tabula,'' incorporating the discoveries of Abel Tasman, was published in 1648. This map was revolutionary in that it "depicts the solar system according to the heliocentric theories of Nicolaus Copernicus, which show the earth revolving around the sun.... Although Copernicus's groundbreaking book ''On the Revoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-title Catalogue
A short-title catalogue (or catalog) is a bibliographical resource that lists printed items in an abbreviated fashion, recording the most important words of their titles. The term is commonly encountered in the context of early modern books, which frequently have lengthy, descriptive titles on their title pages. Many short-title catalogues are union catalogues, listing items in the custody of multiple libraries. Online short-title catalogues in fact tend to record complete (and therefore longer) title transcriptions. Examples * STC: A. W. Pollard and G. R. Redgrave, editors: ''A Short-Title Catalogue of Books Printed in England, Scotland and Ireland, and of English Books Printed Abroad 1475–1640.'' Second edition, revised and enlarged, begun by W. A.

Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...

Second Life
''Second Life'' is an online multimedia platform that allows people to create an avatar for themselves and then interact with other users and user created content within a multi player online virtual world. Developed and owned by the San Francisco-based firm Linden Lab and launched on June 23, 2003, it saw rapid growth for some years and in 2013 it had approximately one million regular users. Growth eventually stabilized, and by the end of 2017 the active user count had declined to "between 800,000 and 900,000". In many ways, ''Second Life'' is similar to massively multiplayer online role-playing games; nevertheless, Linden Lab is emphatic that their creation is not a game: "There is no manufactured conflict, no set objective". The virtual world can be accessed freely via Linden Lab's own client software or via alternative third-party viewers. ''Second Life'' users, also called ' residents', create virtual representations of themselves, called ''avatars'', and are able to int ...

(n.d.). Definition of 'digitize'. Retrieved December 15, 2021, from https://www.collinsdictionary.com/dictionary/english/digitize The result is the representation of an object, image, sound, document, or signal (usually an analog signal) obtained by generating a series of numbers that describe a discrete set of points or samples. The result is called '' digital representation'' or, more specifically, a '' digital image'', for the object, and ''digital form'', for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numeri ...

Map Collection
A map collection or map library is a storage facility for maps, usually in a library, archive, or museum, or at a map publisher or public-benefit corporation, and the maps and other cartographic items stored within that facility. Sometimes, map collections are combined with graphic sheets, manuscripts and rare prints in a single department. In such cases, the expression "map collection" refers to the whole of the cartographic collection holdings. History Even in medieval libraries, maps formed part of the inventories. According to scholars of the renaissance, maps were collected from the 15th century, either at the court or at naval academies to prepare for voyages of discovery. Over time, new techniques, such as copper engraving, reduced production costs, and assisted in spreading maps more widely. By the 17th century, private map collections were often the basis for public map collections. As early as 1571, for example, the Court Library in Munich, Bavaria, (now the Bavar ...

Digital Images
A digital image is an image composed of picture elements, also known as ''pixels'', each with ''finite'', '' discrete quantities'' of numeric representation for its intensity or gray level that is an output from its two-dimensional functions fed as input by its spatial coordinates denoted with ''x'', ''y'' on the x-axis and y-axis, respectively. Depending on whether the image resolution is fixed, it may be of vector or raster type. Raster Raster images have a finite set of digital values, called ''picture elements'' or pixels. The digital image contains a fixed number of rows and columns of pixels. Pixels are the smallest individual element in an image, holding antiquated values that represent the brightness of a given color at any specific point. Typically, the pixels are stored in computer memory as a raster image or raster map, a two-dimensional array of small integers. These values are often transmitted or stored in a compressed form. Raster images can be created by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
