In John Snow determined the source of a cholera outbreak in London by marking points on a map depicting where the cholera victims lived, and connecting the cluster that he found with a nearby water source. This was one of the earliest successful uses of a geographic methodology in epidemiology. While the basic elements of topography and theme existed previously in cartographythe John Snow map was unique, using cartographic methods not only to depict but also to analyze clusters of geographically dependent phenomena. This work was originally drawn on glass plates but later plastic film was introduced, with the advantages of being lighter, using less storage space and being less brittle, among others.

This system will assist fire managers with the mitigation of the harmful effects of wildfires by producing forest fire hazard maps and will function as a valuable planning tool for fuel reduction efforts at the European level.

It is expected that forest managers, fire professionals and land owners will be interested in the product, because it will assist with the mitigation of the harmful effects of wildfires by mapping fire hazards on a daily basis.

What are the innovative features? The tool provides the user with the ability to integrate structural fuel models, topography, etc and "dynamic" factors air temperature, relative humidity, fuel moisture content, etc into the GIS environment, to easily assess fire hazard on a daily basis.

How does it serve the European cause and promotes the philosophy of Fire Paradox?

The tool is expected to assist fire managers with the mitigation of the harmful effects of wildfires by producing maps on forest fire hazards.

It will also function as a valuable planning tool for fuel reduction efforts at the European level. Leader Contact General objectives This software can produce fire hazard maps, on a daily basis, by combining "static" structural fuel models, topography, etc and "dynamic" factors air temperature, relative humidity, fuel moisture content, etc.

It contributes to enhance the assessment of the wild-land fire risk. It is organised on five different topics: The user will be able to integrate structural fuel models, topography, etc and "dynamic" factors air temperature, relative humidity, fuel moisture content, etc into the GIS environment, to easily assess fire hazard on a daily basis.

Major results The major steps which have been realized are: Calculation of a structural index probability of occurrence by means of logistic regression 1. Choice of the most significant structural factors from a list of factors of potential significance.

Possible factors to include are: Assessment of the relative significance weight of each factor. Weights are calculated in such a way that maximizes the possibility that observed fire occurrence historic events is predicted from the observed values of factors taken into consideration.

Calculation of a daily index Fire Weather Index 3. The Composite Index is the product of the structural and the daily indices 7. Calculation of the Hazard in WUI index IR The calculation requires a polygon dataset containing values for the variables of interest WUI typology, ecological, topographical and socioeconomic data.

The index is a combination between 3 indices:Property Search. Use the WinGIS Property Search to search for parcels in Winnebago, Boone and Stephenson Counties. Search by parcel number (PIN) or parcel address to zoom to an aerial view of your property as well as view an array of property details.

What is GIS? A geographic information system (GIS) is a computer-based tool for mapping and analyzing things that exist and events that happen on earth. StreamStats version 4 is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes.

Geographic Information Systems

CRGIS is a map-based inventory of the historic and archaeological sites and surveys stored in the files of the Pennsylvania State Historic Preservation Office (PA SHPO).

The Pennsylvania Historical and Museum Commission (PHMC) has been collecting information concerning archaeological sites and historic resources for the greater part of a century. Geographic Information Systems (GIS) is a computer-based method for collecting, managing, analyzing, modeling, and presenting geographic or spatial data.

GIS software allows you to overlay maps and datasets and query them in terms of their spatial relationships to each other.
