+== '''Objective 0.1.6d - Being able to get all the properties of a raster (all the “Get” functions).''' ==
+
+'''RT_SRID(raster|geometry) -> integer'''[[BR]]
+Return the SRID associated with the raster.
+
+'''RT_Width(raster) -> integer'''[[BR]]
+Return the width of the raster.
+
+'''RT_Height(raster) -> integer'''[[BR]]
+Return the height of the raster.
+
+'''RT_PixelSizeX(raster) -> float64'''[[BR]]
+Return the georeference's X pixel size of the raster. [http://en.wikipedia.org/wiki/World_file See].
+
+'''RT_PixelSizeY(raster) -> float64'''[[BR]]
+Return the georeference's Y pixel size of the raster. [http://en.wikipedia.org/wiki/World_file See].
+
+'''RT_RotationX(raster) -> float64'''[[BR]]
+Return the georeference's X rotation.
+
+'''RT_RotationY(raster) -> float64'''[[BR]]
+Return the georeference's Y rotation. [http://en.wikipedia.org/wiki/World_file See].
+
+'''RT_UpperLeftX(raster) -> float64'''[[BR]]
+Return the georeference's X-coordinate of the center of the upper left pixel. [http://en.wikipedia.org/wiki/World_file See].
+
+'''RT_UpperLeftY(raster) -> float64'''[[BR]]
+Return the georeference's Y-coordinate of the center of the upper left pixel. [http://en.wikipedia.org/wiki/World_file See].
+
+'''RT_GeoReference(raster) -> string'''[[BR]]
+Return the georeference of the raster as a string representing the 6 doubles of an equivalent world file (including the carriage return). [http://en.wikipedia.org/wiki/World_file See].
+
+'''RT_NumBands(raster) -> integer'''[[BR]]
+Return the number of band included in the raster.
+
+'''RT_BandPixelType(raster, integer) -> string'''[[BR]]
+Return the pixel type of the specified 1-based Nth band of raster. Band index is 1-based. The function returns one of the following values:
+  * '''1BB''' - 1-bit boolean
+  * '''2BUI''' - 2-bit unsigned integer
+  * '''4BUI''' - 4-bit unsigned integer
+  * '''8BSI''' - 8-bit signed integer
+  * '''8BUI''' - 8-bit unsigned integer
+  * '''16BSI''' - 16-bit signed integer
+  * '''16BUI''' - 16-bit unsigned integer
+  * '''32BSI''' - 32-bit signed integer
+  * '''32BUI''' - 32-bit unsigned integer
+  * '''16BF''' - 16-bit float
+  * '''32BF''' - 32-bit float
+  * '''64BF''' - 64-bit float
+
+'''RT_BandNoDataValue(raster, integer) -> float32'''[[BR]]
+Return the !NoDataValue of the specified  1-based Nth band of raster. Band index is 1-based. The value is always returned as a float32 even if the pixel type is integer.
