Iowa Geological Survey
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
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

Iowa Geological Survey
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
![Page 24: Iowa Geological Survey Iowa Geographic Information Council 2007 NSDI 50 States Cap Grant A Business Plan for the Iowa Geospatial Infrastructure (IGI) Jim](https://reader035.vdocuments.net/reader035/viewer/2022062518/56649e005503460f94aea17f/html5/thumbnails/24.jpg)

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
![Page 28: Iowa Geological Survey Iowa Geographic Information Council 2007 NSDI 50 States Cap Grant A Business Plan for the Iowa Geospatial Infrastructure (IGI) Jim](https://reader035.vdocuments.net/reader035/viewer/2022062518/56649e005503460f94aea17f/html5/thumbnails/28.jpg)
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)

Iowa Geological Survey
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%.
![Page 32: Iowa Geological Survey Iowa Geographic Information Council 2007 NSDI 50 States Cap Grant A Business Plan for the Iowa Geospatial Infrastructure (IGI) Jim](https://reader035.vdocuments.net/reader035/viewer/2022062518/56649e005503460f94aea17f/html5/thumbnails/32.jpg)
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

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

Status of statewide 2’ pixel 4-band spring ortho-imagery program
• USGS provided $200k for 17 counties in NW Iowa, flown Spring 2007 – viewable on ISU Ortho Server (a few areas had to be reflown this year)
• Nothing new flown in 2008 (too rainy anyway!)• $500k from Pooled Technology Fund available this
year for Spring 2009 flights• July 14 - Applied for additional $500k for Spring 2010
flights• For new flights, DNR looking at RFP or RFI on COE
contract by the end of summer

National Hydrography Dataset
• Create a local resolution stream and water body dataset using NHD attributes conflated to lidar-based high-resolution stream networks – include NWI attributes
• $50k for USGS for pilot for 27 12-digit HUCs. Only 1750 HUCs left to go!

Iowa Geological Survey
Planning Ahead for IGI• 2009 Pooled Technology Grant submitted
July 14• Asking for $650,000 to create GIS coverages
for address points and structures for 30-50 counties
