Maps are stored as graphs, or two dimensional arrays of objects with attributes of location and category, where some common categories include parks, roads, cities, and the like. A map database represents a road network along with associated features. Map providers can choose various models of a road network as a basis to formulate a database.
Each of these programs also created its own data file structures, primarily focused on finding innovative ways to store the spatial or geometric aspect of the data in the most efficient and error-free way. One example of this was the POLYVRT software and data structure (1973) from the Harvard Laboratory for Computer Graphics and Spatial ...
National Transfer Format (NTF) – National Transfer Format (mostly used by the UK Ordnance Survey) Shapefile – open, hybrid vector data format using SHP, SHX and DBF files (by ESRI) Spatial Data File – high-performance geodatabase format, native to MapGuide (by Autodesk) TIGER – Topologically Integrated Geographic Encoding and Referencing
A simple vector map, using each of the vector elements: points for wells, lines for rivers, and a polygon for the lake A vector dataset (sometimes called a feature dataset) stores information about discrete objects, using an encoding of the vector logical data model to represent the location or geometry of each object, and an encoding of its ...
An extension to an existing database software program (most commonly, an object-relational database management system) that creates a geometry datatype, enabling spatial data to be stored in a column in a table, but also provides new functions to query languages such as SQL that include many of the management and analysis functions of GIS. This ...
Unlike the OGC Web Map Service (WMS), which portrays spatial data as static, server-rendered images (maps), the Web Coverage Service delivers underlying data values along with their detailed descriptions. This enables a rich syntax for queries against the data and returns information with its original semantics, rather than just pictures ...
Karbon – Scalable vector drawing application in KDE; Krita – Digital painting, sketching and 2D animation application, with a variety of brush engines; LazPaint – Lightweight raster and vector graphics editor, aimed at being simpler to use than GIMP; LightZone – Free, open-source digital photo editor software application.
SOSI is a geospatial vector data format predominantly used for exchange of geographical information in Norway. [1]SOSI is short for Samordnet Opplegg for Stedfestet Informasjon (literally "Coordinated Approach for Spatial Information", but more commonly expanded in English to Systematic Organization of Spatial Information).
