The GeoPackage standard describes a set of conventions (requirements) for storing vector features, tile matrix sets of imagery and raster maps at various scales, schema and metadata. A GeoPackage can be extended by using the extension rules as defined in clause 2.3 of the standard.
It is intended as an extensible architecture; the first accelerator implemented is called tile matrix multiply unit (TMUL). [5] [6] In Intel Architecture Instruction Set Extensions and Future Features revision 46, published in September 2022, a new AMX-FP16 extension was documented. This extension adds support for half-precision floating-point ...
SQLite (/ ˌ ɛ s ˌ k juː ˌ ɛ l ˈ aɪ t /, [4] [5] / ˈ s iː k w ə ˌ l aɪ t / [6]) is a free and open-source relational database engine written in the C programming language.It is not a standalone app; rather, it is a library that software developers embed in their apps.
wxSQLite3 is a C++ wrapper around the public domain SQLite 3.x database and is specifically designed for use in programs based on the wxWidgets library.. wxSQLite3 does not try to hide the underlying database, in contrary almost all special features of the current SQLite version 3.47.2 are supported, like for example the creation of user defined scalar or aggregate functions.
SpatiaLite is a spatial extension to SQLite, providing vector geodatabase functionality. It is similar to PostGIS, Oracle Spatial, and SQL Server with spatial extensions, although SQLite/SpatiaLite aren't based on client-server architecture: they adopt a simpler personal architecture. i.e. the whole SQL engine is directly embedded within the application itself: a complete database simply is an ...
A Web Map Tile Service (WMTS) is a standard protocol for serving pre-rendered or run-time computed georeferenced map tiles over the Internet. The specification was developed and first published by the Open Geospatial Consortium in 2010.
Spatialite – a spatial extension to SQLite, providing vector geodatabase functionality. It is similar to PostGIS, Oracle Spatial, and SQL Server with spatial extensions; Simple Features – Open Geospatial Consortium specification for vector data
Vector tiles, tiled vectors or vectiles [1] are packets of geographic data, packaged into pre-defined roughly-square shaped "tiles" for transfer over the web. This is an emerging method for delivering styled web maps , combining certain benefits of pre-rendered raster map tiles with vector map data.
