  1. GIS Resources For Journalists

  2. Outline • What is GIS? • Why use GIS? • How are journalists using GIS? • Data driven journalism • What do you need to make and share maps • Data • Software • Online Apps • Some coding skills (python, html)

  3. What does GIS stand for? • Geographic Information Systems • often defined as a computerized database management system for capture, storage, retrieval, analysis, and display of spatial data. - www.cml.upenn.edu/what_is_gis.htm • allows the user to create visual displays using tabular information.

  4. GIS is in reality nothing more than a large database with a geographic component. The power behind GIS is in the attributes attached to the features...allows for more complex analysis based on more than just geographic location.

  5. How GIS works • GIS breaks anything that has a geographic location into: • Vector Data: • Points - GPS points, address points, treeocations, etc. • Lines – rivers, railroads, streets, corridors, etc. • Polygons – political boundaries, lakes, building footprints, etc. Image Source: www.esri.com 2013

  6. Why Use GIS/Maps • Layer the different datasets to do geographic analysis (analysis based on geographic location) • Map Where Things Are – Where is the Ukraine located? • Map Quantities – The total number of acres devoted to coal mining in the state of West Virginia. • Map Densities - Population per square mile. • Find What’s Inside - How many historic homes are located within a proposed neighborhood rehabilitation zone. • Find What’s Nearby - How many parks/recreation areas are there within a ¼ mile from my house? • Map Change – Urban Sprawl, Rainforest depletion Source: www.esri.com 2013

  7. Random GIS Fact • In 1854 Dr. John Snow analyzed geographic data to determine the source of a cholera epidemic in London. • The earliest recorded uses of Geographic Information techniques • The source was a contaminated well.

  8. First, You need:1. data (your own or someone else’s)2. software to filter and map complexdata3. apps to visualizeand share the map with others Making a Map

  9. Data • What makes data “spatial”? • Must have a geographic component • Address • Lat/Long coordinates • Tied to a location such as a state, city, region, service area, census block. • When should you create and share maps of your data? • Only if it enhances the data and makes it easier for users to understand and comprehend!! • A picture is worth a thousand words!

  10. Maps need base or “reference” data • helps those viewing the maps figure out exactly what and where they are looking at. • Orthophotography • Streams • Watershed Boundaries • Jurisdictional Boundaries • Streets • …..and many more datasets, such as parcels, zoning boundaries, contours, soils, etc. Source: www.esri.com 2013

  11. Your data • GPS points • Georeferencing - a historic map or image • Geocoding addresses • Heads-up-digitizing • Analysis Tools with GIS Software • Mobile Mapping – cellphones, tablets • Upload from a database (Excel, Access, etc.) • Stream from Twitter or other social media

  12. Government data sources • Data.gov • ARDA – the association of Religion Data Archives • Census.gov • CIA World Factbook • Eurostat • Global Health Observatory • Harvard Dataverse Network • HUD.gov • International Monetary Fund (IMF) Data • NOAA • IndianaMap (or other state GIS data collection) • UNdata – United Nations Statistics Division • Community Commons

  13. You can use a GIS Software Program or Online Applications.The number of options is daunting! You have data, now to analyze and create the map…

  14. GIS Software

  15. Esri ArcGIS Desktop

  16. Quantum GIS (QGIS) • Open Source GIS- which means FREE! • Runs on Linux, Unix, Mac OSX, Windows and Android. PostGIS • Adds spatial support to the PostgreSQL database program. • Allows you to write queries based on Geographic location. • QGIS can connect to a PostGIS database for viewing and editing free of charge.

  17. Map Maker • Map Maker Gratis – free GIS for Windows • Fully functional map production program • Doesn’t have an online map sharing component • http://www.mapmaker.com/v3/products.htm

  18. Visualizing and Sharing Your Data

  19. Google Maps http://www.walkscore.com/score/94043

  20. Google Earth http://www.brocku.ca/maplibrary/digital/War1812/WarOf1812.php

  21. Tableau Public • Free data visualization tool • http://www.tableausoftware.com/public/gallery

  22. MapBox • Powered by Open StreetMap • Foursquare • Evernote • Financial Times • Pinterest http://www.mapbox.com/showcase/ Source:mapbox.com/showcase, 2013
