    What is (a) GIS? Let’s find out in twenty-minutes or

    less (or more)! Matt Kenny August 7th, 2012

    The Flow • Overview of GIS Components • GIS at

    RIDOLFI – Current Projects • GIS at RIDOLFI – Future Goals • Conclusion 2
  3. 3.

    From the Literature • “A computer based system to aid

    in the collection, maintenance, storage, analysis, output, and distribution of spatial data and information.” – Bolstad, 2005 • “A computer system for capturing, storing, querying, analyzing, and displaying geospatial data.” – Chang, 2008 • “[The] integration of data, hardware, and software designed for management, processing, analysis, and visualization of georeferenced data.” – Netler and Mitasova, 2005. 3

    From the Practitioners • “GIS is the name given to

    ‘doing nifty things with spatial data’…” – Dave Bouwman • “GIS works hand-in-hand with other disciplines and domains in order to solve problems, just as the hammer works hand-in- hand with other disciplines, e.g. structural, HVAC, electrical, plumbing – to create a building.” – Dave Smith 5

    With Great Power Comes…. 8 • Maps can provide a

    sense of legitimacy. – Improper understanding of data, or personal bias can misrepresent the mapped phenomena. – It’s the job of the GIS Analyst to properly represent those phenomena.

    With Great Power Comes…. 12 • Intentionally, maps can be

    used to alter spatial perceptions and promote points- of-view.

    Yakama Nation Site Prioritization • Effort undertaken through EPA’s Tribal

    Response Program • Question: “Of all the hazardous sites along the Columbia River, which should we target for cleanup?” 15
  10. 17.

    Collection 17 Storage Analysis Display Collection Data Sources • EPA

    Facility Registry System (FRS) • WA Ecology Facility/Site Database • OR DEQ Environmental Cleanup Site Information (ESCI)
  11. 18.

    Collection 18 Storage Analysis Display Collection Supporting Datasets • EPA’s

    Enforcement and Compliance History Online (ECHO) • EPA’s Risk-Screening Environmental Indicators (RSEI) dataset • Lower Columbia River Estuary Partnership’s (LCREP) Estuary Partnership’s Program Database • National Land Cover Database 2006 (NLCD2006) raster dataset
  12. 19.

    Storage 19 Storage Analysis Display Collection • Microsoft SQL-Server Makes

    Basin Wide Analysis Possible • ~ 114,000 Sites Evaluated • > 18 GB In Size • Data Conflation is Key

    Analysis 20 Storage Analysis Display Collection Master Site List Within

    1/4-Mile to the CR; Downstream of Bonneville Dam Target Specific Federal- Or State- Level Programs Remove Sites In Developed Areas (NLCD) Exclude Superfund or Portland Harbor Sites Filtered Master Site List Include EPA ECHO Violators Include Existing YN TRP Sites Calculate Proximity to Restoration Sites (LCREP) Final Site Prioritization List Dataset GIS Process Database Process Legend

    Looking Forward for RIDOLFI • Continuing to Perform Innovative Analyses

    – E.g. Eric’s work with the City of Yakima. • Creating, Analyzing Large-Scale Datasets – E.g. Yakama Nation TRP; Hanford PED. • Decision Support Tools 22
  15. 23.

    Decision Support Tool • Empower the Decision Maker to Utilize

    GIS without knowing it – GIS/Database workflows are complicated! Remove the learning curve. – Answer a focused question through the execution of a parameter-based model. • Empower the GIS Staff to focus on the data, not the deliverables 23
  16. 24.
  17. 26.

    Decision Support Tool • Question: “As a planner, what are

    the tradeoffs associated with a given shoreline development and its conservation potential?” 26
  18. 28.

    What is GIS? • I think it is a set

    of tools, people, and practices in a state of radical-change. • Moving from desktop only GIS to a hybridization of desktop-web based tools, depending on the user. • “We are probably at a similar point in GIS evolution as word processing was 30 or 40 years ago.” – Don Meltz, “GIS Is Dead – Long Live GIS”. 28
  19. 30.

    What is GIS? • “GIS is the name given to

    “doing nifty things with spatial data”. For a long time, these nifty things were a black art that required special software, and arcane training. These days are ending.” – Dave Bouwman • The barrier to entry will become lower, but the specialized tools and users will never go away. 30

    Digital/Paper Confluence • FieldPapers.org • Create a paper atlas, collect

    information via markup, upload as georeferenced image to traditional GIS software. 32
