I am trying to write a loop to load .adf files into QGIS and create a contour map from each one. The response to an older question about loading .adf files (here: Loading *.adf files into QGIS?) was very good but I would like to know how to perform the same action using Python.

    Not sure but as the post you linked uses the Add Vector Layer menu and since OGR supports Arc/Info Binary Coverage type files, perhaps you can try the following: layer = QgsVectorLayer("/path/to/file.adf", "layer_name", "ogr"). – Joseph Sep 15 '15 at 15:22
  • @Joseph I tried this and got the error 'Layer is not valid' – Thomas McGregor Sep 15 '15 at 17:27

    You need to find out what the layer name is, if it is a vector "coverage". Try PAL, ARC, or CNT rather than "layer_name". http://www.gdal.org/drv_avcbin.html (Also, for sanity purposes please confirm that it's not a raster ADF according to the notes on that page). – mdsumner Sep 15 '15 at 22:08
  • It is in fact a raster file 'hdr.adf', that was the problem. Thanks – Thomas McGregor Sep 16 '15 at 17:48

Turns out that the file was indeed a raster file 'hdr.adf'. The python script iface.addRasterLayer(fileName, rasterName) worked
