Geography….!
Geographic Information Systems
An organized collection of computer hardware, software, geographic data, and personnel designed to effectively capture, store, manipulate, analyze, and display all forms of geographically referenced information.

GIS Life Cycle
GIS Life Cycle: Sampling & Data Model
• Data Model: A Conceptual description (Mental Model) of how data are organized for use by the GIS.
• They are not always designed to deal with the limitations of computers
GIS Data Models
Attribute Data Models
Spatial Data Models
Raster Data Model
Vector Data Model
Image Data Model
GIS Life Cycle: Data Transfer
• Data Structures: Methods of representing the data model from w/in the computer– Vector [Arc/Nodes] Data Structures – Raster [Grid] Data Structures
GIS Life Cycle: Data Analysis
Spatial Data: Geographically referenced data, identified according to Location.
Points Lines Polygons
Non-Spatial [Attribute Data ]: The attributes refer to the properties of spatial entities.
Spatial DataCommunity-
developed data sets
Framework Data sets
GIS Life Cycle: Reports
• Mapping is a key feature of a GIS but it is NOT the whole story.
• Spatially Intelligent Reports : Provides links between point, lines, areas, grids & Attributes in a database.– Identify trends on the data.– Create new relationships from the data.– View complex relationships between data sets.– Make better decisions.

Weather Dashboard
Objective of the tool?– Develop a web interface that allows Travelers to visualize the
weather data by day, zoom into areas of significant “Impact” to provide appropriate metrics related to the weather, policies, and claims.
Targeted Users– Application will be utilized primarily by the “CAT Center” to
enhance event response activity.
