====== Raster → Drivers ======

As stated in the [[:wiki:designimplementation:raster|Raster Base Concepts]] section, the Raster module provides the classes foundation for creating implementations that truly access data in a specific format or system. These implementations are called hereinafter as **Raster Drivers**. We can classify the drivers in two categories as follows.

===== Native Drivers =====

**TO BE DONE**

==== GRIB ====

The **[[:wiki:designimplementation:dataaccess:drivers:grib|GRIB native raster driver]]** allows applications to access spatial data stored in a [[http://www.grib.org|GRIB]] file. You can have [[:wiki:designimplementation:dataaccess:drivers:grib|more details about this driver here]].


==== Memory ====

The **[[:wiki:designimplementation:dataaccess:drivers:memory|Memory native raster driver]]** allows applications to manipulate rasters in memory. You can have [[:wiki:designimplementation:dataaccess:drivers:memory|more details about this driver here]].

==== PostgreSQL/PostGIS ====

The **[[:wiki:designimplementation:dataaccess:drivers:postgis|PostGIS native raster driver]]** allows applications to access data stored in a [[http://www.postgresql.org|PostgreSQL]] system with the the geo-spatial extension [[http://postgis.refractions.net/|PostGIS]] enabled. You can have [[:wiki:designimplementation:dataaccess:drivers:postgis|more details about this driver here]].

==== SQLite ====

The **[[:wiki:designimplementation:dataaccess:drivers:sqlite|SQLite native raster driver]]** allows applications to access spatial data stored in a [[http://www.sqlite.org|SQLite]] database. It can access data stored in the geo-spatial extension RasterLite.  You can have [[:wiki:designimplementation:dataaccess:drivers:sqlite|more details about this driver here]].


===== Drivers over Multi-Access Library =====

**TO BE DONE**

==== GDAL ====


The **[[:wiki:designimplementation:dataaccess:drivers:gdal|GDAL raster driver]]** is build on top of [[http://www.gdal.org/|Geospatial Data Abstraction Library (GDAL)]] and it is a multi-driver, allowing applications to access several raster data formats through GDAL. You can have [[:wiki:designimplementation:dataaccess:drivers:gdal|more details about this driver here]].
