  1. JayOSpatial (Twitter) Jaredleeware (LinkedIn) QGIS for the Humanities and Social

    Sciences “Using Open Source Data with Open Source Software” Jared Ware, GISP
  2. Agenda • Purpose • Background • A Sports Example Using

    QGIS and Open Source Data • A Public Policy Example Using QGIS and Open Source Data • Resources • Questions
  3. Purpose • Provide ideas for using open source software and

    data • To create geospatial products • In social sciences and the humanities • Use recent geospatial projects dealing with public policy • Texas policy • Texas data • Build a credible data set from open source data • Obtained from a validated public entity • GIS process provides a solution
  4. Background • Academic • Workshop - Harvard Center for Geographic

    Analysis • Conference - Gerrymandering GIS Project (NACIS 2017) by UT-Austin • Accreditation - open source requirements for undergraduate curriculum • Practical • Research: Addresses needs for humanities and social science crowd • Visualization: Data on a map is more optimal than data in a table • $$$$: Free Software / Free Internet / Free Storage / Free Data Workshop Conference Accreditation Research Visualization $$$$
  5. What Color Is A Tennis Ball? • https://www.theatlantic.com/science/archive/2018/0 2/what-color-tennis-ball-green-yellow/523521/ •

    “Yellow, obviously, I thought, and voted…Of nearly 30,000 participants, 52 percent said a tennis ball is green, 42 percent said it’s yellow, and 6 percent went with “other.” • “…how we label a tennis ball is determined both by perceptual and cognitive factors: the actual physical light entering your eye and ... knowledge about what people have typically labeled the objects.” • What does this mean for a GIS practitioner, a Digital Cartographer, or a Data Scientist?
  6. What Color Is A Tennis Ball? • https://www.rapidtables.com/web/color/Yellow_Color.html What color

    does it need to be to get the point across? Using software and data to create the desired effect. Color Scheme Symbology
  7. Potential GIS Projects: Sports (Tennis) • Types of Humanities Projects

    • University of Texas Men’s Tennis Team – “2019 National Championship Season” • Proliferation of tennis court construction in the late 1970s • Top 100 professional players each year by country • Types of Social Science Projects • Tennis industry revenue by state • Most popular tennis shoes by geolocated Instagram posts • Tennis facility locations and socioeconomics Data Mining Data Formatting GIS Product
  8. QGIS and Open Source Data From Sports to Public Policy

    • …proposed well site is located within 1500 feet of the property line of a child care facility, private school, or primary or secondary public school. • Executive Agency: Railroad Commission of Texas (RRC) • Data Sources: • Railroad Commission of Texas • Texas Education Agency (TEA) • Texas Department of Family and Protective Services The Spatial Component
  9. QGIS Map Options & Plugins • Open QGIS • Version

    3.10 • Plugins • Manage and Install Plugins • MMQGIS • Add a Map • OSM • OSM Type
  10. Schools (Texas) • Go to the TEA Website • Select

    the Current Schools file • Download the file (zip) • Spreadsheet • KML • Shapefile • Geodatabase • Unzip and Import into QGIS • Layer - Add Layer – Add Vector Layer • Click the box next to the layer to make it visible • Double click the layer to open the Layer Properties and Symbology • Select a symbol and color scheme • Determine opacity (0% to 100%) and size • Open the attributes • Right click on the Layer • Open attribute table
  11. Wells (Texas)

  12. Child Care Centers (Texas) Use QGIS to geocode the address

    information & Convert it to a shapefile The child care centers are now features and attributes in QGIS
  13. QGIS – Layers of Information

  14. Reprojection and Buffer Reprojected from geographic (degrees) to a projected

    system (New projection: NAD83 / Conus Albers) “proposed well site is located within 1500 feet of the property line of a child care facility, private school, or primary or secondary public school.”
  15. QGIS Buffer Tool

  16. MMQGIS Buffer Tool

  17. • Focus on the specific issue and communicate the solution

    visually • Familiarity with GIS software and functionality (QGIS videos / blogs) • Data mining, data downloading, data conversion, data formatting • Create a credible data set • Document the process (repeat the process as a quality check) Keys to GIS Project Success “Open source data and open source software”

  19. Questions “how we label a tennis ball is determined both

    by perceptual and cognitive factors” Thank you for attending
