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


Elements of IGI


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


Framework layers – ground control


Framework Layers – high resolution orthophotos


Framework Layers – transportation – road centerlines


Framework Layers – hydrography - streams


Framework Layers – cadastral – parcelsand right of ways


Framework Layers – address points


Framework Layers – structures – building footprints


Framework layers – elevation – digital elevation models and 2’ contours


Framework Layers – what we need


Framework Layers – what we have now


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

• 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

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


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”


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)

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

Structures• Building

footprints from lidar

• $50k CAP grant to build web editing tool

• Structures and roads into IGI


Structures (BTW: Lidar Status)


Moving Ahead with IGI

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


Moving Ahead with IGI

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!


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

• Develop a web-based geocoding service that can validate and standardize addresses, perform single and batch geocoding, web-tools to update and maintain databases

• If approved, money available July 2009• Apply again next year for second half


Planning Ahead for IGI

Local Government Innovation Fund• $800,000 available (though funding

may disappear into flood relief efforts)• Use ROI data from GITA study to build

pieces of COUNTY GIS SERVICE BUREAU

1. Work with counties that do not have GIS2. Coordinate joint ortho-imagery

acquisitions3. Training county staff to use GIS

IGI Outreach

• Talk to Rebuild Iowa Office about GIS and IGI

• Talk to Lt Gov and “big” agency heads• Talk to State CIO• Talk to county supervisors - ISAC Fall

School – Nov 19-21 Coralville• Talk to ICIT• Get towns and cities involved in next
