'''ESRI ArcInfo Grid''' (or '''ESRI Grid''', '''ArcGrid'''; &amp;quot;ArcInfo&amp;quot; may also be spelled '''Arc/Info''') is a geospatial raster/grid format. There is a binary version ('''ADF'''), and an &amp;quot;ASCII&amp;quot; version of the format. &lt;br /&gt;
&lt;br /&gt;
== Identification ==&lt;br /&gt;
An ADF &amp;quot;file&amp;quot; is actually a directory containing multiple files (most with an '''.adf''' extension) that don't all use the same format. Some of the files start with bytes {{magic|00 00 27 0A FF FF}}.&lt;br /&gt;
