3 Mapping seems trendy when did it start?

4 Why use maps A map is worth a thousand numbers

5 Why use maps continued

6 Why use maps continued Explore your region/test ideas: Show the geographical location and spatial distribution of data Compare different areas

20 GIS versus free mapping software GIS means geographic information systems Most organizations work on issues that are geographic neighborhoods, cities, counties, regions, states, etc. Using Geographic Information Systems (GIS) can help groups be more effective in carrying out their programs.

21 How do I decide what program to use? Consider what you need to know to answer your question How many layers of data will you need? more layers = more complex software How much capacity does your organization have? training, software, etc.

22 More considerations for choosing mapping programs Do you need to publish the image? How much do you need to customize the map? How often do you need to make maps?

23 Questions so far?

24 Ok! Let s make a map!

25 Step 1: Go to PolicyMap.com

26 Step 1: Go to PolicyMap.com And register for a free account!

27 Step 1: Go to PolicyMap.com Take a second to look at this beautiful creature

28 Step 2: Enter your city

29 Step 2: Or zip code (for more specificity)

30 Any questions so far?

31 Step 3: Start adding data

32 Step 3: Start adding data PolicyMap has pre-loaded data layers and data points

33 Step 3: Start adding data Data layers and data points are created from public data sources, primarily the Census and American Community Survey (ACS) You can combine data layers and data points and multiple data points, but cannot display more than one data layer at a time Most data layers are accessible on the free version

34 Step 3: Start adding data

35 Curious about where the data comes from? Click on this data descriptor for a full breakdown of what data sources are used

36 Step 4: Lookin at your data On the left side of the map, you ll find a breakdown of what you re looking at with a key for what the different colors mean These aren t changeable with the free version

37 Step 4: Lookin at your data Play around with different data layers the more data you look at, the better you understand your community These data can be used to better articulate your community s needs, risk factors, and differences from other communities to your coalition, stakeholders, and wider community

38 Step 4: Lookin at your data Some data layers and points that may be particularly helpful: Age (15-17, 18-20) K-12 schools Colleges and universities Beer, wine, and liquor stores per 100,000 people

39 Any questions?

40 Discuss with a neighbor! What data are most interesting to you? Is this sort of mapping helpful in your work? How so? If not, why not? What data are most applicable to your work? Who would benefit from seeing mapped data about your area?

41 Limitations of PolicyMap Nothing s perfect, and PolicyMap is no exception. With a free account, you can t: Map your own data points Access some of their data Do 3-layer maps

42 Other resources Google Earth Pro Is now free, but offers very limited demographic information (median income and average age not much else) BatchGeo Allows you to map addresses from Excel onto Google Maps, doesn t have data layers or points internally
