This is probably old news to some, but I just learned that MrSID (.sid) files have different 'generations' of file formats - so there are MrSID Generation 2, Generation 3, and Generation 4 files. Does anyone know what generation of .sid is supported in ArcGIS 9.3?

Thanks!

Generation 3 is supported: Data Formats Support in ArcGIS 9.3

Generation 4 support is targeted for 10.1 according to ESRI forums.

  • Thanks! I was on the same page earlier...strange that the same information isn't on the 'Supported raster dataset file formats' or 'About MrSID rasters' pages. – Timothy Michael Aug 8 '11 at 15:18
  • Yeah I noticed that too, a bit misleading unless you look at both pages :( – Sasa Ivetic Aug 8 '11 at 15:59

with your title and a bit of google i've got this link:

http://webhelp.esri.com/arcgiSDEsktop/9.3/index.cfm?TopicName=Data_formats_supported_in_ArcGIS

generation 3 is ok.

Generation 4 seems ok only with arcgis 10 (http://www.lizardtech.com/downloads/plugins.php)

  • Thanks...see my comment to the previous answer, I was close to finding it on my own, but there was different information on different pages. – Timothy Michael Aug 8 '11 at 15:20
  • Np, was a bit too long to check my facts and click send ^^ – Cédric Despierre Corporon Aug 8 '11 at 15:33
