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.
- 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 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.
