Here is SRI’s project from 1994 that showed similar capabilities (and the same name) and was one of the reasons the court decided against the claimants in their lawsuit against Google:

I wonder why the footer said it is dated to January 26, 1995 (after ITU in Kyoto 19 September, 1994) while the first page said April 22, 1994?

This PDF file is encoded PDF format version 1.3 witch was released in 2000. It is coherent with the informations stored in the PDF heather fields telling us this file was created 02.02.2000, 10:20 and last changed 02.02.2000, 18:20 by Acrobat Distiller 4.0 .

So at lest we can say this PDF file here is not an authentic one from 1995, witch of cause not necessarily means there could not be another PDF file somewhere else(?).

Well I found in internet archive an older version of the same document in PS format that was captured at May 16, 1997 : https://web.archive.org/web/19970516152226/http://www.ai.sri...

This PS still contains same dates. On footer dates January 26, 1995 while the first page says April 22, 1994.

I also found the old SRI TerraVision homepage captured at May 16, 1997: https://web.archive.org/web/19970516142933/http://www.ai.sri...

As well as the old datacenter page referring to SRI Terravision captured at June 5, 1997: https://web.archive.org/web/19970605180747/http://www-itg.lb...

And here is the newer homepage of the later program version SRI TerraVision II captured at December 02, 2000 still containing some short promo videos of the software: https://web.archive.org/web/20001202100300/http://www.tvgeo....

I need to check this site more deep but on first impression the SRI TerraVision I in 1997 and SRI TerraVision II in 2000 as shown in the linked videos are kind of inferior in sense of performance and capability compared to Art+Com TerraVision in 1994. Especially the videos from 1997(running on SGI) looked really bad and more like an early prototype. Just the 2000(on PC) videos SGI TV looked a bit better. All the TerraVisions programs may share the same name for whatever reason(?), but I would assume they do not use the same Algorithms. If Keyhole/Google "borrowed" ideas for Google Earth I would guess they did not copy them from SRI TerraVision, but from Art+Com TerraVision. But how knows?

If Brian from SGI was the connection to Keyhole/Google he could be also the connection to the MAGIC project from SRI since they use the same SGI Onyx at the beginning as Art+Com.

Who were SRI?

Why did it have the same name as the original Terra Vision?

Stanford Research Institute https://en.wikipedia.org/wiki/SRI_International

The same name is a really good question. But since SRI TerraVision and the Art+Com TerraVision both seems to be started at the same time around 1993 and both use the same SGI hardware (an Onyx) I could image that Brian from SGI was in contact with both teams.

This SRI document is based on research funded by a ARPA grant:

"This work was supported in part by the Advanced Research Projects Agency under Contract F19628-92-C-0071."

Which implies that it was in development long before the date on the PDF.

Earth mapping was a very hot field in the 1980s with most of it being funded by intelligence agencies and classified.
