2. Purpose
• Make digital representation of 1896 tornado path
and destruction through St. Louis and E St. Louis
• Use historical narrative and ArcGIS
tornados.slpl.org tornados.slpl.orgwww.usgennet.org
3. Outline
• What is HGIS?
• HGIS Background
• St. Louis Tornado
• Process of Creation
• Historical narrative
& images
• Difficulties
• Further Research
• Conclusions
tornados.slpl.org
4. Geographic Information Systems
• GIS
• Computer-based mapping and spatial analysis
technology
• Link points, lines, areas and information
• Overlay map layers to see connections
• Cluster/dispersion of spatial phenomena
5. Historical Geographic Information
Systems
• HGIS
• Map historical data
• Census
• Statistics
• Econometric data
• Digitize historical maps
• Process historical attribute
data
• Originally developed for
environmental
sciences, military, and
cartography
www.gisforhistory.org
6. HGIS Uses
• Environment
• Track species’ changing habitat
• Track migratory routes
• Social History
• American Indian agricultural irrigation
• National Historical Geographic Information
Systems
• “aggregate census data and GIS-compatible boundary
files for the United States between 1790 and 2012”
7. Benefits of HGIS
• Focus on environmental studies in a geographical
perspective
• Determine historical accuracy
• Predict spread of species
• Define spatial processes in ways historians
haven’t been able to
• Display changing boundaries of administrative
units
• Visualization
• Can allow new questions to develop
• New answers to old questions
8. HGIS Projects
• Historical GIS Canada
• National Historical Geographic Information
Systems
• China HGIS
• Electronic Cultural Atlas Initiative
• HGIS Germany
• GHIS Netherlands
• Mammoth Cave Historical GIS
9. 1896 St. Louis Tornado
• 3rd Deadliest tornado
• Most costly tornado
• $3.8 million in damages
• 255 fatalities
• Estimated F4 on Fujita scale
• Wednesday, May 27th
• Began near city hospital,
ended in E St. Louis
• Began ~5:00 p.m.
• 1 mile wide
• 7.5 miles long
10. Process of Creation
• The Great Cyclone at St. Louis
and East St. Louis, May 27,
1896
• Primary source of information
• Historical narrative primarily
from Julian Curzon
• Compiled from accounts and
photos immediately following
tornado
11. Process: Choose a Basemap
• 1914 TIFF of St. Louis
• Parker, Engraving Co.
• Not identical to 1896 streets
• Good detail
• North-aligned
• Legible
• St. Louis, St. Louis County, East St. Louis
included
12.
13. Creation: Georeference
• = to associate something with actual physical
locations
• 2010 Topologically Integrated Geographic
Encoding and Referencing (TIGER) roads
• Overlay on 1914 basemap
• Match to basemap
• 740 georeferenced points
17. Plot the Tornado
• “In a tempest of discordant sound the tornado
swooped down on the Poorhouse, worked its will
and continued on its way. The Female Hospital,
just across the street, was right in its path, but the
vagaries of a tornado are hard to understand. It
took a slight trend to the east and south…”
• Where did it actually start?
• Estimate
18. Interpreting Text
“The large furniture store of Wm. Ottenad, at
Soulard and Broadway, was completely destroyed.
Ottenad, his wife and a clerk and a driver were
buried in the wreck…”
• Interpreted: Three dead at Soulard and Broadway
20. Interpreting Text
“The roof of the Sumner High School, on Eleventh
and Spruce streets, took a vacation…”
• Interpreted: Sumner High School on 11th and
Spruce was damaged.
• Data were assigned to the center of the
intersection
27. Future Work
• Plot addresses
• Finish digitizing of all city elements
• Make accessible online
• Show path of tornado with time
• Path of destruction
• Process of creation could be extrapolated to other
studies

A database that can be used and manipulated in whatever ways needed for projects or research pertaining to St. Louis around the turn of the century, or tornadoes in general
Visualization can be more revealing than verbally discussing data
28 people died here. There were separate sections in the book that gave different numbers. One part said that three people were killed on one of the corners and 25 people were killed on another corner. Then the caption to this picture said that 28 people died at the intersection.
Multiple strands (based on historical accounts)
Uncertainty on where it actually touched down and where it actually dissipated
