Often the data is a format that is jp2 (jpeg 2000) and sid (lizardtech)
which are compressed formats.
- You must have the JP2 extension installed if you want to view imagery files in ArcView that have been compressed with the JP2 process.
- To download and view maps in the MrSID format you need a MrSID viewer. LizardTech has discontinued this viewer and no longer offers support on the product. The following location provides access to this viewer, but does not provide help or support for the product. Download the MrSID viewer.
