Iowa Geographic Information Council 2007 NSDI 50 States Cap Grant A Business Plan for the Iowa Geospatial Infrastructure (IGI) Jim Giglierano james.giglierano@dnr.iowa.gov August 28, 2008
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
IGI Framework Layers • Geodetic control: county GPS control monuments and NGS benchmarks - counties • Ortho imagery: BW, color and CIR orthorectified aerial imagery – counties, state, federal • Administrative boundaries: city, county and state boundaries - counties • Cadastral data: public land survey section corners, section lines and parcel boundaries - counties • Transportation: road centerlines, railroads, trails, airports, waterways – counties and state • Elevation: digital elevation models and contours - state • Hydrography: rivers and streams, water bodies, watershed boundaries - state • Address points – counties and state • Structures: 2D building footprints, bridges, towers – counties and state
Framework layers – elevation – digital elevation models and 2’ contours
ROI Study – Costs Benefits of IGI • Interviewed Counties with GIS • Interviewed Counties without GIS • Interviewed State and a few Federal Agencies • Utilities and others
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
Costs to Participate in IGI • GIS Coordinator – providing data • County Staff – learning to use lidar elevation, other data layers • Participate in Imagery for the Nation (IFTN) ~ $5k-6k in real costs per county per year to participate in IGI
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
One County Stand Alone $3,000,000 $2,500,000 $2,000,000 Cumulative Costs $1,500,000 Cumulative Benefits $1,000,000 $500,000 $0 2008 2017 2026 2011 2014 2020 2023 Counties adopting GIS: parcel maintenance and tax assessment only
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
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).
One County with IGI $3,000,000 $2,500,000 $2,000,000 Cumulative Costs $1,500,000 Cumulative Benefits $1,000,000 $500,000 $0 2008 2011 2014 2017 2020 2023 2026 County Adopting GIS with IGI Assistance – sharing costs with 2 other counties
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”
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
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)
Cumulative Benefits Equal Cumulative Costs Subtract Costs from Benefits Break Even NPV ROI Pay Back Divide Benefits by Cost Time from Now to BreakevenPoint Quantitative Measures
Multiagency Cumulative Costs and Benefits $350,000,000 $300,000,000 $250,000,000 Cumulative Costs $200,000,000 $150,000,000 Cumulative Benefits $100,000,000 $50,000,000 $0 2008 2011 2014 2017 2020 2023 2026 Multi-agency IGI Study
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%.
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
ROI Study Summary! • IGI is possible, and financially compelling • Everyone benefits by participating in IGI • Move ahead, cautiously optimistic, to funding sources in the next year
Things to Consider • This analysis is fairly conservative – only measured the value to county, state and limited number of outside groups – DID NOT INCLUDE BENEFITS TO CITIES/TOWNS • Did not fully include Federal benefits • Did not fully include Private benefits • Did not fully include benefits to economic development and emergency management efforts
