What is tp8 file? How to open tp8 files?
File type specification:
The tp8 file extension is associated with the MODTRAN, a narrow band model atmospheric radiative transfer code developed by US Air Force Research Laboratory.
It is a standard atmospheric band model for the remote sensing community.
The tp8 file stores spectral output data.
This tp8 file type entry was marked as obsolete and no longer supported file format.
This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
