What is the IGI?• Iowa Geospatial Infrastructure (IGI) is Iowa’s
contribution to the National Spatial Data Infrastructure (NSDI)
• IGI’s central focus is on the collection of consistent, common, integrated, standardized local, state, federal and other GIS data layers (“framework” data layers in NSDI terminology) that are freely available to the public through the Internet
• IGI will follow NSDI practices for metadata and data standards, and use Iowa’s data clearinghouse for data discovery
• IGI includes people, technology and agreements to make this happen
Iowa Geological Survey
Components of IGI
1) Framework GIS Data2) Infrastructure Technology3) People4) Community
Iowa Geological Survey
IGI Framework Layers1. Geodetic control: county GPS control monuments and
NGS benchmarks - counties2. Ortho imagery: BW, color and CIR orthorectified aerial
imagery – counties, state, federal3. Administrative boundaries: city, county and state
boundaries - counties4. Cadastral data: public land survey section corners,
section lines and parcel boundaries - counties5. Transportation: road centerlines, railroads, trails, airports,
waterways – counties and state6. Elevation: digital elevation models and contours - state7. Hydrography: rivers and streams, water bodies,
watershed boundaries - state8. Address points – counties and state9. Structures: 2D building footprints, bridges, towers –
counties and state

ROI Study – Costs Benefits of IGI
• Interviewed Counties with GIS
• Interviewed Counties without GIS
• Interviewed State and a few Federal Agencies
• Utilities and others
Iowa Geological Survey
Benefits to Counties with GIS Participating in IGI
• Using lidar in county engineer office for road maintenance $12k-90k/yr
• Using lidar in county engineer office for surveying and design $10k-50k/yr
• Cost avoidance for web mapping server $10k/yr
• Cost avoidance for aerial photography $20k/yr through participation in IFTN
From $50k to $150k in benefits per county per year
Iowa Geological Survey
Costs to Participate in IGI
• County GIS staff has to provide data to IGI
• County Staff – learning to use IGI layers, ie. lidar elevation
• Participate in Imagery for the Nation (IFTN)
~ $5k-6k in real costs per county per year to participate in IGI
Iowa Geological Survey
IGI County GIS Service Bureau
• Gets county data into IGI, helps counties do GIS more effectively
• Job functions: about 4 FTEs– County IGI coordinator– County ortho-imagery coordinator– GIS web application developer– GIS tech/training specialist
• Funded by the state – free to counties who participate in IGI

ROI Results:Counties WITHOUT GIS
• Typical approach for counties wanting to adopt GIS:– Initial outlay of $200k to $500k for GPS control,
orthos, centerlines and parcel conversion project– GIS staff: coordinator and half-time tech– 2 or more copies of desktop GIS software; GIS
hardware, servers, plotter– Web mapping server– OR all above services provided by a vendor
• Many of the remaining counties can’t afford startup or maintenance costs of GIS

Problems• “Standard” GIS approach is not cost effective for
smaller counties if parcel maintenance and tax assessment are the only applications of GIS
• Many counties WITH GIS are not getting all the possible benefits of their GIS if all they do is parcel maintenance and tax assessment
• May feel compelled to sell data to recoup costs • IGI (and therefore NSDI) won’t happen without
major assistance to local data producers to lower their ongoing costs, and expand their overall benefits of having a GIS
Iowa Geological Survey
IGI Benefits
• IGI County Coordinator helps with regional approach starting a GIS– Sets up agreement to share a GIS person among
3 counties– Assists with contracting for GIS data conversion
among 3 or more counties; parcel maintenance outsourcing
– Data hosting and web application by service bureau
• Benefits of access to IGI data (lidar contours, etc).

IGI State GIS Service Bureau*
• Helps get state data into IGI and helps state agencies do GIS more effectively
• Job functions – 4 FTEs– GIS database/clearinghouse administrator– Web application developer– GIS tech/training specialist– IGI state agency coordinator
probably located at state emergency management agency• Funded by the state – free to state agencies• Geocoding is a big need for state agencies
* Not equivalent to a state agency “bureau”
Iowa Geological Survey
The IGI ROI Calculation – 20 year cost scenario
• 20 counties w/o GIS will build county GIS programs, phased into GIS/IGI over 10 years
• 79 counties w/ GIS, will participate in IGI, phased in over 10 years
• State and federal agencies will provide funding GIS service bureaus and IFTN
• Costs of participating were phased in over first 10 years, then full cost of maintaining for next 10 years
Iowa Geological Survey
Summary of IGI Costs• $385k/yr state service bureau• $600k/yr new orthos and lidar• $385k/yr county service bureau• $300k/yr county data projects• $2M one time data projects (hydro,
structures, address points)• 1M/yr county data costs (new and existing)• (1M/yr federal contribution to IFTN –not
counted in analysis)Total of about $3M/yr average cost over 20
years (2M state, 1M county)

Major Findings – ROI Spreadsheets
• The 20 year analysis shows Net Present Value of $271M and Return on Investment of 24.21%. Present value of total 20 yr costs is $56M (about $3M a year).
• Sensitivity analysis shows that delayed adoption of GIS, with counties phasing in GIS capabilities over 20 years instead of the desired 10 year span, does not result in extreme detriment to the project. NPV is reduced from $271M to $230M and ROI is reduced from 24% to 22%.
Iowa Geological Survey
Major Findings – Economic Development Interviews
• A Chamber of Commerce interview cited GIS as contributing more than 50% of the resources needed to bring in new business
• Estimate of $13.5M/year in benefits to a community of modest size
• Did not use this in the ROI spreadsheets but it certainly shows the potential for growth in this area
Iowa Geological Survey
ROI Study Summary!
• IGI is possible, and financially compelling
• Everyone benefits by participating in IGI
• Move ahead to funding sources in the next year
