Subject: "Digitizing Sanborn Fire Insurance Maps...."

Arlitsch, Kenning.  "Digitizing Sanborn Fire Insurance Maps for a
Full Color, Publicly Accessible Collection"  D-Lib Magazine 8(7/8)
(July/August 2002)

(http://www.dlib.org/dlib/july02/arlitsch/07arlitsch.html). -

This piece describes the first project to create full-color, freely
accessible versions of old Sanborn Fire Insurance MapsTM, which are
interesting and detailed historical records of U.S. communities. The
maps were scanned at approximately 5,000 x 4,000 pixels and saved as
uncompressed TIFFs (average file size 60MB). The maps are served
online
as MrSID (r) files, which requires users to have the free plug-in
installed. With the plug-in, users can either view the entire map or
zoom in on details. CONTENTdmTM was selected as the underlying
metadata
database. - RT
