"Plexis Group, LLC director Scott Stephens was a featured
speaker at the North Carolina GIS Conference 2001. Stephens
addressed attendees as part of the conference's special segment on
GIS and information systems integration. He gave a presentation
entitled "Linux Powered GIS: Two Case Studies."
"Stephens' presentation illustrated two very diverse uses of GIS
through the Linux operating system. The first user, Landmark
Information Group, Ltd., employs a 1 Ghz Linux PC to run Linux
GenaMap, a product of Gena Warehouse Ltd. Using this operating
system and software, Landmark Information Group provides free
access to first edition historical ordnance survey maps of Great
Britain, between 1846 and 1899. The web site gets as many as 50,000
hits per day. Visitors can choose to simply view maps, or they may
also be purchased online. Maps are printed on parchment paper to
maintain the appearance of age."
"Stephens also talked about the city of Bloomington, Indiana, a
client of Plexis Group. Bloomington is a city of about 80 square
miles, with 2.2 gigabytes of map data and 18.4 gigabytes of image
data. Until last year the city's municipal water, wastewater and
stormwater utility had a Novell IT system powered by 14 old servers
with only 25 gigabytes of storage space. Remote and home users were
required to use a dial-up account. In 2000, Bloomington upgraded to
a new IT system with about 500 gigabytes of storage space on 12
Linux servers. They now have eight remote locations connected by
ISDN, and home users can now connect through VPN."
