MapInfo TAB Format
The MapInfo TAB format is a geospatial vector data format for geographic information systems software. It is developed and regulated by MapInfo Corporation as a proprietary format. File components The basic file components for a MapInfo Professional data set relate to the two basic environments for working in MapInfo; "Browser View" and "Mapper View". As with most other GIS packages, several files are required to allow the user to open a data set for viewing within MapInfo Professional. The most basic view would be the browser view only. This environment provides storage of attribute or object data and is represented like a spreadsheet. In this simplified scenario, no geographic information is available. Minimum files required for the basic MapInfo Professional browser environment: *.TAB (The ASCII file that is the link between all other files and holds information about the type of data set file ) *.DAT (The file that stores the attribute data. This is a dBase III DBF file) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MapInfo Corporation
MapInfo Corporation, initially incorporated as Navigational Technologies Incorporated, was a company that developed location intelligence software. It was headquartered in North Greenbush, New York. Its products included a desktop mapping application, various map and demographic data products, and some web-based applications. It acquired several other companies in order to market their software, data, or services directly. It was acquired in 2007 by Pitney Bowes, and became Precisely in December 2019 when acquired by Syncsort. History MapInfo was founded in 1986 by Laszlo Bardos, Andrew Dressel, John Haller, and Sean O’Sullivan. The four were students at nearby Rensselaer Polytechnic Institute who wanted to develop an inexpensive mapping tool for the PC. They got a contract to develop bus routes for a local school district, and used the money to develop their first product. They contacted Michael Marvin early in the company's history for advice on how to form the com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geospatial
Geographic data and information is defined in the ISO/TC 211 series of standards as data and information having an implicit or explicit association with a location relative to Earth (a geographic location or geographic position). It is also called geospatial data and information, georeferenced data and information, as well as geodata and geoinformation. Approximately 90% of government sourced data has a location component. Location information (known by the many names mentioned here) is stored in a geographic information system (GIS). There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data. Fields of study Geographic data and information are the subject of a number of overlapping fields of study, mainly: * Geocomputation * Geographic information science * Geoinformatics * Geomatics * Geovisualization This is in addition to other more specific branches, such as: * Cartography * Geodesy * ...

Vector Graphics
Vector graphics is a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing ''hardware'', vector ''data models'' and file formats, as well as the ''software'' based on these data models (especially graphic design software, computer-aided design, and geographic information systems). Vector graphics is an alternative to raster or bitmap graphics, with each having advantages and disadvantages in specific situations. While vector hardware has largely disappeared in favor of raster-based monitors and printers, vector data and software continues to be widely used, especially when a high degree of geometric precision is required, and when complex information can be decomposed into simple geometric primitives. Thus, it is the preferred model for domains such as engineering, architecture, surveying, 3D render ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographic Information System
A geographic information system (GIS) is a type of database containing Geographic data and information, geographic data (that is, descriptions of phenomena for which location is relevant), combined with Geographic information system software, software tools for managing, Spatial analysis, analyzing, and Cartographic design, visualizing those data. In a broader sense, one may consider such a system to also include human users and support staff, procedures and workflows, body of knowledge of relevant concepts and methods, and institutional organizations. The uncounted plural, ''geographic information systems'', also abbreviated GIS, is the most common term for the industry and profession concerned with these systems. It is roughly synonymous with geoinformatics and part of the broader geospatial field, which also includes GPS, remote sensing, etc. Geographic information science, the academic discipline that studies these systems and their underlying geographic principles, may also ...

MapInfo Professional
MapInfo Pro is a desktop geographic information system (GIS) software product produced by Precisely (formerly: Pitney Bowes Software and MapInfo Corporation) and used for mapping and location analysis. MapInfo Pro allows users to visualize, analyze, edit, interpret, understand and output data to reveal relationships, patterns, and trends. MapInfo Pro allows users to explore spatial data within a dataset, symbolize features, and create maps. History Version 4 of the product, released in 1995, saw the product renamed to "MapInfo Professional". Version 9.5 was released in June 2008. Version 9.5.1 was released in December 2008. The primary enhancements in these releases included the use of a new graphics engine which allows for translucency and anti-aliasing when displaying maps. A set of CAD like editing tools were also added in this release. Version 10 was released in June 2009. The primary enhancements included a more intuitive user interface, including a rewritten Layer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Set
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. In the open data discipline, data set is the unit to measure the information released in a public open data repository. The European data.europa.eu portal aggregates more than a million data sets. Some other issues ( real-time data sources, non-relational data sets, etc.) increases the difficulty to reach a consensus about it. Properties Several characteristics define a data set's structure and properties. These include the number and types of the attributes or variables, and various statistical measures applic ...

DBase
dBase (also stylized dBASE) was one of the first database management systems for microcomputers and the most successful in its day. The dBase system includes the core database engine, a query system, a forms engine, and a programming language that ties all of these components together. dBase's underlying file format, the file, is widely used in applications needing a simple format to store structured data. Originally released as Vulcan for PTDOS in 1978, the CP/M port caught the attention of Ashton-Tate in 1980. They licensed it and re-released it as dBASE II, and later ported it to IBM PC computers running DOS. On the PC platform, in particular, dBase became one of the best-selling software titles for a number of years. A major upgrade was released as dBase III, and ported to a wider variety of platforms, adding UNIX, and VMS. By the mid-1980s, Ashton-Tate was one of the "big three" software publishers in the early business software market, the others being Lotus Developmen ...

R-tree
R-trees are tree data structures used for spatial access methods, i.e., for indexing multi-dimensional information such as geographical coordinates, rectangles or polygons. The R-tree was proposed by Antonin Guttman in 1984 and has found significant use in both theoretical and applied contexts. A common real-world usage for an R-tree might be to store spatial objects such as restaurant locations or the polygons that typical maps are made of: streets, buildings, outlines of lakes, coastlines, etc. and then find answers quickly to queries such as "Find all museums within 2 km of my current location", "retrieve all road segments within 2 km of my location" (to display them in a navigation system) or "find the nearest gas station" (although not taking roads into account). The R-tree can also accelerate nearest neighbor search for various distance metrics, including great-circle distance. R-tree idea The key idea of the data structure is to group nearby objects and represent the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
