Elizabeth and Listers,
Here's two links for historical maps that you can easily browse and in many
cases download the data in MrSid format [note that usually such data is not
available rectified or georeferenced, although the metadata often contains
basic coordinate info indicating the geographic extent covered by the map.
Also, note that most of these maps are for the US\:
Library of Congress Map Collections Home Page
http://lcweb2.loc.gov/ammem/gmdhtml/gmdhome.html
David Rumsey Collection (Cartography Associates)
http://www.davidrumsey.com/
We are currently working with the David Rumsey Collection to provide their
historical maps in an internet GIS context with other current/modern
geospatial datasets (USGS DRG's, DOQ's, satellite imagery, air photos, and
planimetric layers such as infrastructure, streets, boundaries, hydro,
etc.). We use ESRI's ArcIMS technology along with our Java-based
Maplicity(tm) and MapImager(tm) products to provide a fully interactive,
lightweight, easy to use GIS interface for web browser clients, and includes
image analysis functionality (such as overlay/swipe, blend/fade, spectral
enhancements, create/save/download georeferenced image, etc.) With Maplicity
and MapImager, web browser-based visitors to the Rumsey Collection will be
able to conduct their own real-time interactive comparisons of historical
maps with current geospatial reference data.
We have a full-featured on-line Maplicity and MapImager demo at our website
(www.telemorphic.com) which includes a map service with comprehensive
geospatial data for the San Francisco Bay Area, as well as two Rumsey
Collection historical maps (San Fran 1914 Tourist Map and 1926 SF Bay
Navigation Chart). In the near future an additional ten Rumsey Collection
historical maps for the San Fran Bay Area will be added to the on-line site.
One obvious example of change over the past 70's years in the Bay Area can
be seen by using MapImager's image overlay and swiping function to
interactively compare the 1926 Nav. Chart and the modern DRG's or DOQ's.
You will quickly see that much of what is present day San Francisco and the
East Bay was actually covered by water in 1926 (part of the Bay itself!).
As far as these types of on-line internet GIS tools and historical maps for
Yugoslavia and the Balkans, I can't help you (unless you have the current
and historical data of interest, and want to build an ArcIMS and
Maplicity/MapImager powered site similar to our demo site). We also offer
fully customized versions of Maplicity and MapImager to meet customers'
specific needs.
Hope the above links help, and please feel free to contact us if we can be
of further assistance. I would be happy to talk you through the on-line
demo over the phone sometime, and/or discuss your specific needs for
internet GIS and integration of historical maps. Cool stuff!!
Best regards,
Todd
