Hi Jim -
Here are a few of the libraries that have Web sites utilizing our MrSID image
compression software and free image server for making available historic maps
and other digital images to online users. Enjoy.

Library of Virginia - Board of Public Works collection
The records of the Board of Public Works (1816-1903) are a unique source
of information on social history, economics, commerce, and engineering
in Virginia. The maps, drawings, and plans constitute an important
pictorial and cartographic history of Virginia, particularly during the
first half of the nineteenth century. The Library of Virginia (Richmond)
presents more than 750 digitized map images from its collection.

National Library of the Netherlands and the British Library - Atlas Van
der Hagen and Atlas Beudeker
The Atlas Van der Hagen consists of four leather bound volumes, each
containing about 100 sheets, compiled at the end of the seventeenth
century. The atlas is made up of about 450 maps in different sizes and
materials. All the images of the Atlas Van der Hagen were digitized. The
five continents are represented in maps and prints.
The name Atlas Beudeker commemorates the eighteenth-century Amsterdam
merchant Christoffel Beudeker (1675 -1756) who compiled these twenty-four
(of the original 27) large folio volumes. Each volume contains an
average of a hundred to a hundred and fifty sheets onto and between which
some large single or several smaller prints have been mounted. Only one
volume of the Atlas Beudeker was digitized. The whole forms a
comprehensive topographical display of the Low Countries.
This site is a joint project of the National Library of the Netherlands
and the British Library. It presents 584 historic atlases scanned at 400
DPI creating source files of between 80 and 150 Mb in original size
taking up 80 Gb of space. These historic atlases are now available for
multi-resolution browsing across the Internet as MrSID PIF files. The
PIF files are between 1.3 and 4 Mb and the total collection now takes
up less then 2 Gb.

The United States Library of Congress - Panoramic Map Collection
The panoramic map was a popular cartographic form used to depict U.S.
and Canadian cities and towns during the late nineteenth and early
twentieth centuries. Panoramic maps are non-photographic representations
of cities portrayed as if viewed from above at an oblique angle. Although
not generally drawn to scale, they show street patterns, individual
buildings, and major landscape features in perspective.
The digital images were created by staff in the Geography and Map Division
by scanning the original map on a large-format (24 x 34 inches) flatbed
scanner using RGB (red- green-blue) color separation. Each image was
produced by scanning the item at 300 DPI creating TIFF files which average
approximately 180Mb.
The TIFF files were compressed using MrSID at a ratio of 22:1 resulting in
files averaging 8Mb without experiencing any loss of information.

University of Montana - EOS Image Server
The University of Montana Earth Observing System (EOS) Education Project
recently launched their EOS Image Server utilizing the MrSID Web
Development Kit for Windows NT. The EOS Education Project's primary
mission is to explore interactive ways to make remote sensing imagery
from NASA's EOS missions accessible to the global K-16 education
community. The EOS Image Server and MrSID compression technology make
large remote sensing images available across the Internet and provide
a powerful file format for download.

Montana State Library - Montana Natural Resource Information System (NRIS)
Established in 1985, the Montana Natural Resource Information System
(NRIS) was designed to simplify the task of identifying and acquiring
natural resource information. As a program of the Montana State Library,
NRIS makes information on Montana's natural resources easily and readily
accessible. Serving government agencies, business and industry, and
private citizens, NRIS operates a clearinghouse and referral service
to link users with the best sources of information and service.
NRIS has reformatted the state's 24k DRGs into 60 by 30-minute tiles
corresponding to USGS 1:100,000 scale map sheets. MrSID has achieved
a significant compression ratio on the size of these files and, more
importantly, enabled direct browsing of these images over the web.

UMass Amherst Libraries - The F. W. Beers atlases
The F. W. Beers atlases for Berkshire, Hampden and Hampshire counties
are located in the Special Collections and Archives Division of the
Du Bois Library. This site contains images of historical maps of
Massachusetts, primarily from the late nineteenth and early twentieth
century. The source scanned images are approximately 20 Mb and MrSID
was used so they could be viewed directly over the Internet.

City of London, Ontario, Canada - Interactive Map
Surfers visiting the City of London's (ONT, Canada) website are
benefiting from the addition of new interactive London maps which
allow them the ability to locate addresses and gather information
about surrounding schools, parks, and other facilities. The maps,
featuring aerial photos and legal descriptions of London properties,
were used over 3,100 times during February

Boulder Public Library - Carnegie Branch Library for Local History
The Carnegie Branch Library for Local History is a special reference
branch of the Boulder Public Library. Located just north of downtown
Boulder, Colorado, it holds extensive resources for those researching
the history of the Boulder area, including over 200,000 historic
photographs. These images give an intimate and detailed picture of
what life was like in the towns, farms, and mining camps of early
Boulder County

Fairfax County, Virginia - Aerial Photography
Fairfax County Virginia has published a MrSID image file consisting
of a digital orthophoto with 8-foot pixel resolution on its web
site. Additional resolutions are planned for later this year.

University of Arkansas - Center for Advanced Spatial Technologies (CAST)
The results of the Arkansas Gap Analysis Program (GAP) project are now
on-line for viewing. This includes Tassel cap Imagery, Landsat
Thematic Mapper Imagery, and Arkansas Vegetation. Details about the
data mapsets used are also available. The Fayetteville (DOQs) are
also available for viewing.

USGS - Center for Integration of Natural Disaster Information
This site features case studies used to develop new techniques for
the rapid collection, interpretation, and redistribution of
consolidated disaster information and present representative study
results. Large file sized LandSat mosaics associated with Hurricane
Mitch in MrSID format are offered from this site.

USGS - Energy Resources Program
The USGS Energy Resources Program has developed the GEOData-Explorer.
It retrieves information from a database or databases, organizes the
information spatially, and allows the user to more effectively manage
a situation that is dependent on such data.
MrSID imagery in the form of DOQ images has been incorporated into
the display of the Powder River Basin in the Montana/Wyoming project
area. Zoom into the DOQ outlines in order to view the multi-resolution
MrSID images.

Portuguese Army Cartographic Service (IGeoE) - Aerial Photographs of Portugal
IGeoE has produced aerial photos to form a national coverage of
approximately 4,500 infrared photographs. This project is part of a
protocol signed with the NGIC to carry out the orthorectification of
4,500 1-meter false color photographs.

Hi folks,
One of my colleagues is teaching map skills to 4th-6th graders. She's
using MapQuest, National Geographic, eduplace, and Encyberpedia, but she
says she is having trouble finding "historical maps, symbol maps, isometic
maps, and comparison maps..." If in your web-surfing you come across really
good atlas or map sources that would be good for these grades, please send
the URLs to me.
Thank you!
Jim
