<div>Thanks, but I meant the format of datum shift grids used in PROJ.4 for datum conversion (for example file ntf_r93.gsb). May be I should have called it "NTv2 grid format". Meanwhile I found a document of an australian program that uses that grid format and refers a page in Canada, which is not available. Looks like there are different versions of the file format.</div>
<div>I would appreciate any information on the format of the grids available with PROJ. Thanks in advance.</div>
