general-purpose <a href="/wiki/Database" title="Database">database</a> (usually a <a href="/wiki/Relational_database" title="Relational database">relational database</a>) that has been enhanced to include <a href="/wiki/Spatial_data" class="mw-redirect" title="Spatial data">spatial data</a> that represents objects defined in a <a href="/wiki/Space" title="Space">geometric space</a>, along with tools for <a href="/wiki/Information_retrieval" title="Information retrieval">querying</a> and analyzing such data. </p><p>Most spatial databases allow the representation of simple geometric objects such as <a href="/wiki/Point_(geometry)" title="Point (geometry)">points</a>, <a href="/wiki/Line_(geometry)" title="Line (geometry)">lines</a> and <a href="/wiki/Polygon" title="Polygon">polygons</a>. Some spatial databases handle more complex structures such as <a href="/wiki/Solid_geometry" title="Solid geometry">3D objects</a>, <a href="/wiki/Coverage_data" title="Coverage data">topological coverages</a>, linear networks, and <a href="/wiki/Triangulated_irregular_network" title="Triangulated irregular network">triangulated irregular networks</a> (TINs). While typical databases have developed to manage various numeric and character <a href="/wiki/Data_type" title="Data type">types of data</a>, such databases require additional functionality to process spatial data types efficiently, and developers have often added <i>geometry</i> or <i>feature</i> data types. </p><p><b>Geographic database</b> (or <b>geodatabase</b>) is a <a href="/wiki/Georeferenced" class="mw-redirect" title="Georeferenced">georeferenced</a> spatial database, used for storing and manipulating <a href="/wiki/Geographic_data" class="mw-redirect" title="Geographic data">geographic data</a> (or geodata, i.e., data associated with a location on Earth),<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>a<span class="cite-bracket">]</span></a></sup> especially in <a href="/wiki/Geographic_information_systems" class="mw-redirect" title="Geographic information systems">geographic information systems</a> (GIS). Almost all current relational and object-relational database management systems now have spatial extensions, and some GIS software vendors have developed their own spatial extensions to database management systems. </p><p>The <a href="/wiki/Open_Geospatial_Consortium" title="Open Geospatial Consortium">Open Geospatial Consortium</a> (OGC) developed the <i><a href="/wiki/Simple_Features" title="Simple Features">Simple Features</a></i> specification (first released in 1997)<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> and sets standards for adding spatial functionality to database systems.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> The <i>SQL/MM Spatial</i> ISO/IEC standard is a part of the structured query language and multimedia standard extending the Simple Features.<sup id="cite_ref-Kresse2012_4-0" class="reference"><a href="#cite_note-Kresse2012-4"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Characteristics">Characteristics</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Spatial_database&action=edit&section=1" title="Edit section: Characteristics"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The core functionality added by a spatial extension to a database is one or more <i>spatial datatypes</i>, which allow for the storage of spatial data as attribute values in a table.<sup id="cite_ref-GISTBOK_5-0" class="reference"><a href="#cite_note-GISTBOK-5"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Most commonly, a single spatial value would be a <a href="/wiki/Geometric_primitive" title="Geometric primitive">geometric primitive</a> (point, line, polygon, etc.) based on the <a href="/wiki/Data_model_(GIS)#Vector_data_model" title="Data model (GIS)">vector data model</a>. The datatypes in most spatial databases are based on the OGC <a href="/wiki/Simple_Features" title="Simple Features">Simple Features</a> specification for representing geometric primitives. Some spatial databases also support the storage of <a href="/wiki/Raster_graphics" title="Raster graphics">raster data</a>. Because all geographic locations must be specified according to a <a href="/wiki/Spatial_reference_system" title="Spatial reference system">spatial reference system</a>, spatial databases must also allow for the tracking and transformation of coordinate systems. In many systems, when a spatial column is defined in a table, it also includes a choice of coordinate system, chosen from a list of available systems that is stored in a lookup table. </p><p>The second major functionality extension in a spatial database is the addition of spatial capabilities to the query language (e.g., <a href="/wiki/SQL" title="SQL">SQL</a>); these give the spatial database the same <a href="/wiki/Spatial_analysis" title="Spatial analysis"> query, analysis, and manipulation operations</a> that are available in traditional GIS software. In most relational database management systems, this functionality is implemented as a set of new functions that can be used in SQL SELECT statements. Several types of operations are specified by the <a href="/wiki/Open_Geospatial_Consortium" title="Open Geospatial Consortium">Open Geospatial Consortium</a> standard: </p> <ul><li>Measurement: Computes line length, polygon area, the distance between geometries, etc.</li> <li>Geoprocessing: Modify existing features to create new ones, for example by creating a buffer around them, intersecting features, etc.</li> <li>Predicates: Allows true/false queries about spatial relationships between geometries. Examples include "do two polygons overlap?" or 'is there a residence located within a mile of the area we are planning to build the landfill?' (see <a href="/wiki/DE-9IM" title="DE-9IM">DE-9IM</a>)</li> <li>Geometry Constructors: Creates new geometries, usually by specifying the vertices (points or nodes) which define the shape.</li> <li>Observer Functions: Queries that return specific information about a feature, such as the location of the center of a circle.</li></ul> <p>Some databases support only simplified or modified sets of these operations, especially in cases of <a href="/wiki/NoSQL" title="NoSQL">NoSQL</a> systems like <a href="/wiki/MongoDB" title="MongoDB">MongoDB</a> and <a href="/wiki/CouchDB" class="mw-redirect" title="CouchDB">CouchDB</a>. </p> <div class="mw-heading mw-heading2"><h2 id="Spatial_index">Spatial index</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Spatial_database&action=edit&section=2" title="Edit section: Spatial index"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>A <b>spatial index</b> is used by a spatial database to optimize <a href="/wiki/Spatial_query" class="mw-redirect" title="Spatial query">spatial queries</a>.
