GDAL
The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It may also be built with a variety of useful command line interface utilities for data translation and processing. Projections and transformations are supported by the PROJ library. The related ''OGR'' library (OGR Simple Features Library), which is part of the GDAL source tree, provides a similar ability for simple features vector graphics data. GDAL was developed mainly by Frank Warmerdam until the release of version 1.3.2, when maintenance was officially transferred to the GDAL/OGR Project Management Committee under the Open Source Geospatial Foundation. GDAL/OGR is considered a major free softw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shapefile
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products. The shapefile format can spatially describe vector features: points, lines, and polygons, representing, for example, water wells, rivers, and lakes. Each item usually has attributes that describe it, such as ''name'' or ''temperature''. Overview The shapefile format is a digital vector storage format for storing geographic location and associated attribute information. This format lacks the capacity to store topological information. The shapefile format was introduced with ArcView GIS version 2 in the early 1990s. It is now possible to read and write geographical datasets using the shapefile format with a wide variety of software. The shapefile format stores the geometry as primitive geometric shapes like points, lines, and polygo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Source Geospatial Foundation
The Open Source Geospatial Foundation (OSGeo), is a non-profit non-governmental organization whose mission is to support and promote the collaborative development of open geospatial technologies and data. The foundation was formed in February 2006 to provide financial, organizational and legal support to the broader Free and open-source geospatial community. It also serves as an independent legal entity to which community members can contribute code, funding and other resources. OSGeo draws governance inspiration from several aspects of the Apache Foundation, including a membership composed of individuals drawn from foundation projects who are selected for membership status based on their active contribution to foundation projects and governance. The foundation pursues goals beyond software development, such as promoting more open access to government produced geospatial data and completely free geodata, such as that created and maintained by the OpenStreetMap project.

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] |

ArcGIS
ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri. ArcGIS was first released in 1999 and originally was released as ARC/INFO, a command line based GIS system for manipulating data. ARC/INFO was later merged into ArcGIS Desktop, which was eventually superseded by ArcGIS Pro in 2015. ArcGIS Pro works in 2D and 3D for cartography and visualization, and includes artificial Intelligence (AI). Esri also provides server side ArcGIS software for web maps, known as ArcGIS Server. Product history Prior to the ArcGIS suite, Esri had focused its software development on the command line Arc/INFO workstation program and several Graphical User Interface-based products such as the ArcView GIS 3.x desktop program. Other Esri products included MapObjects, a programming library for developers, and ArcSDE as a relational database management system. The various products had branched out into multiple source trees and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PROJ
PROJ (formerly PROJ.4) is a library for performing conversions between cartographic projections. The library is based on the work of Gerald Evenden at the United States Geological Survey (USGS), but since 2019-11-26 is an Open Source Geospatial Foundation (OSGeo) project maintained by the PROJ Project Steering Committee (PSC). The library also ships with executables for performing these transformations from the command line. History The history of PROJ dates back to the late 1970s, and the first release of PROJ was developed by Gerald Evenden in the early 1980s as a Ratfor program. It was based on the General Cartographic Transformation Package or GCTP, which consisted of Fortran subroutines that could be used to project geographic data. The second release of PROJ from 1985 was rewritten in C to run on UNIX systems. The third release of PROJ from 1990, was expanded to support approximately 70 cartographic projections. Evenden further developed a fourth release in 1994, named P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biotop Invent
''Biotop'' is the second album by German electronic musician Asmus Tietchens, released in 1981 on Sky Records. Tietchens recorded the album at Audiplex Studios with producer and mentor Okko Bekker, who is credited as Rokko Ekbek. Departing from the musical style of the musician's debut album ''Nachtstucke'' (1980), ''Biotop'' contains sixteen short electronic pop tracks that are characterised by their immediate nature but unusual synth lines, tones and melodies. Bekker compared the music to radio time signals. Indeed, the liner notes state the album was performed by Das Zeitzeichenorchester, which translates to The Time-Signal Orchestra, although in reality this is an alias for Tietchens, the album's only performer. The first of four albums Tietchens recorded for Sky Records, ''Biotop'' was released to general acclaim, although it sat in obscurity. It was remastered and re-released on CD with bonus material via Die Stadt in 2003, bringing it renewed critical attention, and again v ...
