What kinds of data?

GDAL's superpower is that it can read or write pretty much any spatial file you throw at it.

A note about the name:

 

"GDAL/OGR" refers to the combined project with both raster & vector tools

• GDAL: raster
• OGR: vector

 

Today, most refer to the combined project as "GDAL"
