Geographic Data Files
Geographic Data Files (GDF) is an interchange file format for geographic data. In contrast with generic GIS formats, GDF provides detailed rules for data capture and representation, and an extensive catalog of standard features, attributes and relationships. The most recent extension expanded applicability further towards pedestrian navigation, 3-D map rendering, and advanced driver-assistance systems (ADAS). GDF is commonly used for data interchange in many industries such as automotive navigation systems, fleet management, dispatch management, road traffic analysis, traffic management, and automatic vehicle location. Originated as a flat plain-text file, GDF is not intended to be used directly for any large scale geographic application and normally requires conversion into a more efficient format. Consumability has been increased with most-recent developments for XML and SQL renditions. The maps in GDF format are provided by many map vendors such as HERE, TomTom, Mapscape BV, ...

Data Exchange
Data exchange is the process of taking data structured under a ''source'' schema and transforming it into a ''target'' schema, so that the target data is an accurate representation of the source data.A. Doan, A. Halevy, and Z. Ives.Principles of data integration, Morgan Kaufmann,s 2012 pp. 276 Data exchange allows data to be shared between different computer programs. It is similar to the related concept of data integration except that data is actually restructured (with possible loss of content) in data exchange. There may be no way to transform an instance given all of the constraints. Conversely, there may be numerous ways to transform the instance (possibly infinitely many), in which case a "best" choice of solutions has to be identified and justified. Single-domain data exchange In some domains, a few dozen different source and target schema (proprietary data formats) may exist. An "exchange" or "interchange format" is often developed for a single domain, and then necessar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automotive Navigation Data
GeoJunxion, formerly AND Automotive Navigation Data (AND), supplies digital map data for GPS-based applications. History AND was founded in 1984 by Hans Abbink and Eiko Dekkers. Surnames of the founders were used to create the company name: AND. The A, Hans Abbink, stepped down as member of the board of directors of AND in September 2000.

Keyhole Markup Language
Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer. It was created by Keyhole, Inc, which was acquired by Google in 2004. KML became an international standard of the Open Geospatial Consortium in 2008. Google Earth was the first program able to view and graphically edit KML files, but other projects such as Marble have added KML support. Structure The KML file specifies a set of features (place marks, images, polygons, 3D models, textual descriptions, etc.) that can be displayed on maps in geospatial software implementing the KML encoding. Every place has a longitude and a latitude. Other data can make a view more specific, such as tilt, heading, or altitude, which together define a "camera view" along with a timestamp or timespan. KML shares some of the same structura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Markup Language
The Geography Markup Language (GML) is the XML grammar defined by the Open Geospatial Consortium (OGC) to express geographical features. GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. Key to GML's utility is its ability to integrate all forms of geographic information, including not only conventional "vector" or discrete objects, but coverages (see also GMLJP2) and sensor data. GML model GML contains a rich set of primitives which are used to build application specific schemas or application languages. These primitives include: * Feature * Geometry * Coordinate reference system * Topology * Time * Dynamic feature * Coverage (including geographic images) * Unit of measure * Directions * Observations * Map presentation styling rules The original GML model was based on the World Wide Web Consortium's Resource Description Framework (RDF). Subsequently, the OGC introduced XML schemas in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GIS File Formats
A GIS file format is a standard of encoding geographical information into a computer file. They are created mainly by government mapping agencies (such as the USGS or National Geospatial-Intelligence Agency) or by GIS software developers. Raster A raster data type is, in essence, any type of digital image represented by reducible and enlargeable grids. Anyone who is familiar with digital photography will recognize the Raster graphics pixel as the smallest individual grid unit building block of an image, usually not readily identified as an artifact shape until an image is produced on a very large scale. A combination of the pixels making up an image color formation scheme will compose details of an image, as is distinct from the commonly used points, lines, and polygon area location symbols of scalable vector graphics as the basis of the vector model of area attribute rendering. While a digital image is concerned with its output blending together its grid based details as an iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business-to-business
Business-to-business (B2B or, in some countries, BtoB) is a situation where one business makes a commercial transaction with another. This typically occurs when: * A business is sourcing materials for their production process for output (e.g., a food manufacturer purchasing salt), i.e. providing raw material to the other company that will produce output. * A business needs the services of another for operational reasons (e.g., a food manufacturer employing an accountancy firm to audit their finances). * A business re-sells goods and services produced by others (e.g., a retailer buying the end product from the food manufacturer). B2B is often contrasted with business-to-consumer (B2C). In B2B commerce, it is often the case that the parties to the relationship have comparable negotiating power, and even when they do not, each party typically involves professional staff and legal counsel in the negotiation of terms, whereas B2C is shaped to a far greater degree by economic impli ...

Phonetic Representation
Phonetic transcription (also known as phonetic script or phonetic notation) is the visual representation of speech sounds (or '' phones'') by means of symbols. The most common type of phonetic transcription uses a phonetic alphabet, such as the International Phonetic Alphabet. Versus orthography The pronunciation of words in all languages changes over time. However, their written forms (orthography) are often not modified to take account of such changes, and do not accurately represent the pronunciation. Words borrowed from other languages may retain the spelling from the original language, which may have a different system of correspondences between written symbols and speech sounds. Pronunciation can also vary greatly among dialects of a language. Standard orthography in some languages, such as English and Tibetan, is often irregular and makes it difficult to predict pronunciation from spelling. For example, the words ''bough'', ''chough'', ''cough'', ''though'' and ''throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Referencing
Linear referencing, also called linear reference system or linear referencing system (LRS), is a method of spatial referencing in engineering and construction, in which the locations of physical features along a linear element are described in terms of measurements from a fixed point, such as a milestone along a road. Each feature is located by either a point (e.g. a signpost) or a line (e.g. a no-passing zone). If a segment of the linear element or route is changed, only those locations on the changed segment need to be updated. Linear referencing is suitable for management of data related to linear features like roads, railways, oil and gas transmission pipelines, power and data transmission lines, and rivers. Motivation A system for identifying the location of pipeline features and characteristics is by measuring distance from the start of the pipeline. An example linear reference address is: Engineering Station 1145 + 86 on pipeline Alpha = 114,586 fee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interoperability
Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information. Types If two or more systems use common data formats and communication protocols and are capable of communicating with each other, they exhibit ''syntactic interoperability''. XML and SQL are examples of common data formats and protocols. Lower-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all the commun ...

International Organization For Standardization
The International Organization for Standardization (ISO ) is an international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and (as of November 2022) it has published over 24,500 international standards covering almost all aspects of technology and manufacturing. It has 809 Technical committees and sub committees to take care of standards development.

Working Group
A working group, or working party, is a group of experts working together to achieve specified goals. The groups are domain-specific and focus on discussion or activity around a specific subject area. The term can sometimes refer to an interdisciplinary collaboration of researchers working on new activities that would be difficult to sustain under traditional funding mechanisms (e.g., federal agencies). The lifespan of a working group can last anywhere between a few months and several years. Such groups have the tendency to develop a ''quasi-permanent existence'' when the assigned task is accomplished; hence the need to disband (or phase out) the working group when it has achieved its goal(s). A working group's performance is made up of the individual results of all its individual members. A team's performance is made up of both individual results and collective results. In large organisations, working groups are prevalent, and the focus is always on individual goals, performan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Committee For Standardization
The European Committee for Standardization (CEN, french: Comité Européen de Normalisation) is a public standards organization whose mission is to foster the economy of the European Single Market and the wider European continent in global trading, the welfare of European citizens and the environment by providing an efficient infrastructure to interested parties for the development, maintenance and distribution of coherent sets of standards and specifications. The CEN was founded in 1961. Its thirty-four national members work together to develop European Standards (ENs) in various sectors to build a European internal market for goods and services and to position Europe in the global economy. CEN is officially recognized as a European standards body by the European Union, European Free Trade Association and the United Kingdom; the other official European standards bodies are the European Committee for Electrotechnical Standardization (CENELEC) and the European Telecommunicati ...
