==== Output Formats ====

Using GDAL, Dinamica EGO can write maps in the following file formats.

File formats marked with a star (*) do not define an extension. To workaround this limitation, Dinamica EGO invents the corresponding extension using the file format description.

<note>
  * The support to AAIGrid (.asc) in GDAL is read only. So, Dinamica EGO provides the writing capability itself. This format can read and write images using [[:Cell Type Type|cell types]] "Signed 32 Bit Integer" and "IEEE 754 32 Bit Real". The cell type is detected automatically.

  * The support to ERMapper (.ers) in GDAL ignores class names. To workaround this limitation, support to reading and writing this file format is provided by Dinamica EGO itself.

===== Workdir/folder Names =====

!!!FIXME


===== Virtual Format =====

GDAL support a virtual file format called [[http://www.gdal.org/gdal_vrttut.html|VRT]]. This format can be used to transform an image defining a different registration info, different classe names and a different color table. A example of a VRT file defined from a two unrelated image files can be found below.
