Maps with RGB information such as orthophotographs or simulation outputs (e.g., waterflow) should be exported as PNG or JPG formats:

 # decompose raster to red, green and blue channels

 r.rgb input=texture red=red green=green blue=blue

 i.group group=texture_group input=red,green,blue

 r.out.gdal input=texture_group output=path/output.PNG format=PNG type=Byte createopt="WORLDFILE=YES"

Vector data including points, lines, and boundary features can be exported using the module v.​out.​ogr :

 v.out.ogr input=vector output=path/output.shp format="ESRI_Shapefile" lco="SHPT=POINT"
