Geography is…

Information about the earth’s surface and things on it (which we all share)

Framework for organizing data Science behind GIS

Geography matters to all of us!

GIS is…

Geographic Information System

Tool to create, visualize, integrate, and analyze data from a geographic perspective

Automated map making to support business functions

GIS is…

Process for creating information that supports the actions and decisions of individuals and organizations

System of hardware, software, data, people, and methods that supports program and resource planning, inventory, management, and evaluation activities

View, interpret and understand data in ways not possible with other tools!

A picture is worth…a thousand rows of data!

Dairy Farms

GIS is used to…

Facilitate communication Promote coordination Solve problems Measure resources Make decisions Understand past and present situations Anticipate future scenarios

GIS is a way to model our world!

REAL WORLD

Integrate data “layers” of different “themes” to model YOUR real world.

GIS is an iterative process…

Think about a place or topic… Ask a question about it… Make a map… Explore patterns that appear… Try different analyses…

Maps that tell a story…

Where is ____? How many/dense ____? What’s inside/outside ____? What’s near ____? How has ____ changed? How do ____ relate? What if ____?

Where is ____?

Find places and things

Determine optimum routesCalculate driving timeEfficiently plan site visitsDefine service areas

See where to take action

Where is ____?

All of us have used a map to figure out where “it” is and how to get there.

Google

Where is ____?

GIS helps us identify the best responder and best route in emergency situations.

Where is ____?

Orthophotography helps us visualize where we are in relation to other features.

How many/dense ____?

Map the quantity of features find places with the “most” or “least”find places that meet specific criteria

Map concentrations of features by area (density) to see distributions

Prioritize and manage actions based on number, least/most, or density

How many/dense ____?

Patterns emerge when you look at the distribution of features.

Earthquake hazard maps are essential for creating and updating building codes. earthquake.usgs.gov

How many/dense ____?

2005 Deer Population Density

Wisconsin DNR

per square mile deer range

What’s inside/outside ____?

What's located or happening inside or outside an area of interest

Prioritize and manage actions based on the location of features within a region, district, zone, territory, etc…

What’s inside/outside ____?

Green Bay city ordinance uses buffer zones around places where children are likely to congregate.

What’s inside/outside ____?

2006 Bio-based Industry Opportunity (BIO) Grants

by Senate District

Use GIS to help inform legislators about what’s happening in their districts!

What’s near ____?

What's located or occurring within some distance of a feature

Prioritize and manage actions near or around a feature

What’s near ____?

Find the closest ATM location to the restaurant you’re eating in before the bill arrives!

What’s near ____?

Potential Critical Facilities in the 100 Year Floodplain

Sheboygan County

How has ____ changed?

Evaluate results of an action or policyHow things behave over time Map conditions before and after an

action or event to see the impact

Decide on a course of action based on historical perspective

How has ____ changed?

How do ____ relate?

Overlay and analyze data that can only be combined by location or areaIntegrate informationDevelop modelsSee in 3-D

Decide on a course of action based on spatial analyses

How do ____ relate?

This groundwater contamination susceptibility model integrates:- Bedrock depth

- Bedrock type

- Soil characteristics

- Surface deposits

- Water table depth

What if ____?

Integrate data from different sources to develop “what if” scenarios

What if ____?

What if the Greenland Ice Sheet melts?

Red areas of southern Florida are susceptible to a five-meter rise in sea

level, based on elevation. Yellow denotes urban areas.

What if…

…state agencies could easily share GIS resources and coordinate GIS activities to support their mutual interests and customers?

…state agencies had a common data “view” that each could use to conduct its business?

State Agency Coordination

Public expects and deserves efficient and effective state government services

Number of citizens, government agencies, and businesses using geospatial technologies (e.g., web maps, GIS, GPS) is increasing

State Agency Coordination

BenefitsSave time and money (in many ways)Send unified message about

geospatial issues to decision makersCollaborate on business needs

assessments, strategic plans, etc…Collect “official” data once – use it

many timesShare training, services, expertise

State Agency Coordination

Data sharing is critical!What exists? Who’s the custodian?How can it be accessed?How easy to integrate with other data?What’s missing? a lot…

Examples: Emergency Response, Homeland Security Infrastructure Program (HSIP)
