IGI and Related GIS Activities

Status July 15, 2010

Ongoing IGI Framework Data Projects

  • Statewide Lidar Project – all 57k square miles of the state have been collected!!! Three deliveries are left - July 15, July 30 and end of August? Some reflights may be necessary this fall and winter.
  • Iowa Geocoding Project – create address points (E911 driveway points and rooftop points) for 50 counties using $650k from pooled technology fund
    • address points for 25 is goal for first year of project, many to be released by GIS Day Nov 17
    • Contract with ISU GIS facility for address points for 15 counties by December 2010 - 10 students working this summer, making good progress
    • Contract with Geocomm to get E911 data from 33+ county dispatch systems - completed
    • Possible contract with ICIT for data repository intern to help collect parcel data - contract still pending
    • Contour shape files, 3 meter DEMs and 1 meter hill shades were created as by-products, and are available on the NRGIS library for 59 counties (19 are partially complete)
    • ISU GIS is setting up an ftp distribution point for IGI files which should be ready by Nov 17 GIS Day - will include orthos in state plane from the 2' statewide project, 2' contours and other data
    • DNR has called all 99 counties to inventory basic framework data layers, with results stored in Ramona tool. Counties wishing to maintain their inventory data please contact us.
    • Project workers from Iowa City and Ames will do a crowdsourcing GPS pilot August 10-11 in Ida County. Using handheld cameras and GPS units, we will photograph buildings and addresses in the towns of Galva, Battle Creek, Holstein, Arthur and Ida Grove and sync GPS location using open source GPicsync software. Ida does not have parcel polygons or address point GIS data. Volunteers are welcome to come and help.
  • Collection of the 2010 2’ 4-band orthos for eastern 41 counties is completed. Delivery of 2' orthos as uncompressed tiles has begun. Delivery should be complete by end of summer.
    • Dan Corbin, Inc. is again providing a horizontal accuracy assessment
  • Iowa County Engineer Association Service Bureau is rebuilding the control point server (county GPS monuments and NGS control markers) - Jon Lubke is collecting control point data from county engineers for inclusion on server

New IGI Projects

  • IGIC's application for $50k to do a 2010 FGDC CAP ROI Case Study was successful. This grant will fund an ROI study of a public-private partnership to build and maintain the IGI, called Iowa One Map - will include ROI data from cities, COGs and utilities – with added emphasis on economic development. GITA is our major partner in this project again. Project has commenced with interviews of city GIS programs and rural electric coops.
  • 2010 NAIP 1 meter color is currently being flown again this summer with federal funding. Iowa partners are contributing an additional $91k for 4th infrared band. Should have county color mosaics around November, 4-band deliveries unknown.
  • Grant from USGS State Liaison office to DNR for updating critical infrastructure structure layers and GNIS database using geocoding products for 10 counties in central Iowa - $50k total, will start late summer.
  • DNR, DOT, Homeland Security and Emergency Management, and Public Health are developing a pilot project for sharing data and web services among state agencies. The pilot project will initially provide DOT and DNR services through ITE's SOA appliance. Hopefully this will provide a basis for future IGI web services that can be used directly or within other applications.
  • Pooled Technology Application for 2 FTEs for 2 years to start a state agency GIS service bureau - awarded $320k. DNR and others will hire contractors for a service bureau to begin work this fall to begin working with state agency GIS projects.

IGI Outreach

  • State agency GIS steering committee and GIS users group met June 17, discussed service bureau, IT consolidation and other projects
  • GIS Day Nov. 17 2010 hosted by ISU and others will celebrate the progress of the Iowa Geospatial Infrastructure. Accomplishments and plans for the future will be presented in Ames and on the Web.

Related GIS Projects

    • High-resolution land cover for state – 1 meter from NAIP, leaf-off, lidar and other input layers - IGWS working on pilot, Lyon and Osceola Counties with 2007 NAIP data, 2' orthos and lidar - there may be some funding from a DNR habitat mapping effort in the near future
    • Floodplain Mapping - $15M to complete floodplain maps for the state – should create hydro-enforced DEMs, contours and hydrography layers as well as approximate DFIRMs for all Iowa counties - two staff persons hired, program manager and GIS analyst – pilot project with Iowa Flood Center for floodplain models for Poweshiek County. Contracting for DFIRMs will start later year. DNR will produce stream centerlines derived from the lidar.
    • ARRA Broadband Mapping - Iowa Utility Board contracted with Connected Nation to map broadband availability in Iowa, view the pdf. Online mapping application was made available at the end of June.
    • Statewide parcel GIS data layer - Ray Willis of Polk County is developing a pilot data set of parcels using FGDC core standard, to be distributed on the ICIT Data Repository. Polk, Linn and Dubuque Counties are available.
    • ICIT Data Repository revamped - Currently 21 counties have some data available in the data repository.
    • DNR completed last summer the 1950's historical aerial photography layer for the state. Both 1950s and 1930s are available on the ISU Ortho server and NRGIS Library. Currently working on scanning and orthorectifying the 1960's data set, which is about 53 counties completed. Check availability in the NRGIS library.
    • USGS is currently producing The National Map US TOPO products for Iowa this year. Most areas of the state are available now at the

USGS Map Store

Possible Future Projects

  • Crowdsourcing event in Fall 2010? Envisioned to be an educational event attracting non-GIS as well as GIS professionals to either a county-wide or community-wide volunteer mapping exercise. Emphasis on mapping the "community fabric" (what makes a place interesting and unique), not just infrastructure or collections of things. Look at using free internet-based mapping applications to display the results of the exercise. Looking for sponsors and volunteers. (DNR is doing a mini-GPS pilot in Ida County towns August 10-11 with summer staff from the geocoding project)

Projects looking for funding

  • NHD attribute conflation on lidar-derived stream network.
  • Geocoding Phase 2 – address points for 50 or so remaining counties, apply for PT funding in July 2010, for July 2011 project continuation
  • County GIS Service Bureau - 4 FTEs requiring about $300k per year of ongoing funding
