  2. Spatiotemporal database - Wikipedia

    en.wikipedia.org/wiki/Spatiotemporal_database

    A spatiotemporal database embodies spatial, temporal, and spatiotemporal database concepts, and captures spatial and temporal aspects of data and deals with: Geometry changing over time and/or Location of objects moving over invariant geometry (known variously as moving objects databases [ 1 ] or real-time locating systems ).

  3. The WKT format can describe not only geographic coordinate reference systems, but also geocentric, projected, vertical, temporal and engineering ones (for example a coordinate reference system attached to a boat). The standard describes how to combine those coordinate reference systems together.

  4. Geospatial metadata - Wikipedia

    en.wikipedia.org/wiki/Geospatial_metadata

    Geospatial metadata (also geographic metadata) is a type of metadata applicable to geographic data and information.Such objects may be stored in a geographic information system (GIS) or may simply be documents, data-sets, images or other objects, services, or related items that exist in some other native environment but whose features may be appropriate to describe in a (geographic) metadata ...

  5. Geospatial PDF - Wikipedia

    en.wikipedia.org/wiki/Geospatial_PDF

    The PDF format is widely accepted and is considered the de facto standard for printable documents on the web. This means that users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard . [ 3 ]

  6. Locality of reference - Wikipedia

    en.wikipedia.org/wiki/Locality_of_reference

    Hierarchical memory is a hardware optimization that takes the benefits of spatial and temporal locality and can be used on several levels of the memory hierarchy. Paging obviously benefits from temporal and spatial locality. A cache is a simple example of exploiting temporal locality, because it is a specially designed, faster but smaller ...

    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

  8. GeoTIFF - Wikipedia

    en.wikipedia.org/wiki/GeoTIFF

    The GeoTIFF format is fully compliant with TIFF 6.0, so software incapable of reading and interpreting the specialized metadata will still be able to open a GeoTIFF format file. [ 1 ] An alternative to the "inlined" TIFF geospatial metadata is the *.tfw World File sidecar file format which may sit in the same folder as the regular TIFF file to ...

    The SAIF project was established as a means of addressing interoperability between different geographic information systems. Exchange formats of particular prominence at the time included DIGEST (Digital Geographic Information Exchange Standard) and SDTS (Spatial Data Transfer Specification, later accepted as the Spatial Data Transfer Standard ...
