Rich, Basically all ERSI products are using GDAL since 9.2.
http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=Supported_raster_dataset_file_formats And they keep using it in 9.3: http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=3005&pid=3004&topicname=Supported_raster_data_file_types It is embedded on ArcObject so even if you write your own ArcObject code to deal with Idrisi RST files, for example, you don't need to think about what is going own under the hood. But there are some formats on the list above that they are not supporting through GDAL but by their own code, GeoTiff, img, so I don't think they are supporting Bigtiff yet. Are they? There was one request started on a discussion on gdal-dev that ESRI should release a free downloadble version of their gdal_i.lib so that programmers would be able to develop driver as GDAL plugins. That is because they added some stuff on the library that makes it binary incompatible with regular GDAL plugins. They were very receptive to the request and we are waiting... What more do you want to know?
