Microsoft TerraServer: World’s Largest Web Database Logs Half Billion Queries in First Two Months

Redmond, Wash., August 26, 1998 — On June 24, Microsoft gave Web users the world. Now, the world is taking notice.

Microsoft TerraServer ( http://www.terraserver.microsoft.com/ ), the world’s largest database on the Web, has become one of the world’s most popular online destinations in its first two months – recording more than a half billion queries and 700 million hits. The site is also a success with net experts, who have awarded it more than six major honors in the past eight weeks.

What has caught everyone’s attention is the world’s largest and most detailed atlas. TerraServer contains more than a trillion bytes of compressed aerial and satellite photographs of the Earth that make up nearly six terabytes of uncompressed data.

A geographer and space-industry consultant wrote,
“I think the work you have done on TerraServer is one of the most impressive things I have ever seen. You have cracked something that the space industry has struggled with for years – easily accessible image databases. Great!”

When Microsoft first launched TerraServer, the site received up to 30 million hits per day. The unprecedented demand created bottlenecks for some users trying to access it. Microsoft solved those problems by adding Web server capacity, and the site has run successfully around the clock ever since.

That performance demonstrates the reliability and scalability of both Microsoft SQL Server version 7.0 Enterprise Edition and Microsoft Windows NT Server Enterprise Edition, which can support more than 10,000 users simultaneously. It also demonstrates Microsoft SQL Server’s superb support for data access on the Web.

Key awards and honors for TerraServer include the following:

  • The Tech 10 – TerraServer called one of the 10 best technology sites of the month by the Tech Museum of Innovation in Silicon Valley

  • Digital’s Site of the Month – Top honors to TerraServer from the Digital Web Gallery

  • Best of the Net – Top honors to TerraServer from The Mining Company

  • Scout Report Selection – Chosen by the Internet Scout Project

  • S.P.A.C.E. Site of the Week from the National Space Society

  • Exploratorium Ten Cool Sites Award

Microsoft created TerraServer in partnership with Compaq Computer Corp., the U.S. Geological Survey (USGS) and Aerial Images Inc., the provider of SPIN-2 high-resolution satellite and digital imagery. SPIN-2 data is imagery acquired from SOVINFORMSPUTNIK, a branch of the Russian Space Agency. Additional partners include Legato Systems Inc., Kodak and Storage Technology Corp.


Since June, Microsoft has added another 50GB of data, including the Great Pyramids of Egypt and cities including Berlin and New Orleans .
