IGI and Related GIS Activities

Status Oct 20, 2010

Ongoing IGI Framework Data Projects

  • Statewide Lidar Project – all 57k square miles of the state have been collected!!! All the data has been delivered. Initial processing to blocks is completed. Derivative products continue. 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 counties 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 completed 12 counties so far.
    • Contour shape files, 3 meter DEMs and 1 meter hill shades created from lidar for all 99 counties, and most are available on the NRGIS library, to be completed by Nov 17
    • 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
    • Project workers from Iowa City and Ames completed a crowdsourcing GPS pilot August 10-11 in Ida County. Using handheld cameras and GPS units, we photographed buildings and addresses in the towns of Galva, Battle Creek, Holstein, Arthur and Ida Grove and sync GPS location using open source geotagging software. Ida does not have parcel polygons or address point GIS data. 13 volunteers helped out.
    • 2nd GPS crowdsourcing event held Oct 16 in Greenfield, in Adair County. Six project staff and 12 volunteers had a good time with Ginny Kuhfus, Greenfield Chamber of Commerce director.
  • Collection of the 2010 2’ 4-band orthos for eastern 41 counties is completed. Delivery of 2′ orthos as uncompressed tiles is complete and CIR and RGB mosaics are available on the NRGIS library.
    • Dan Corbin, Inc. is again providing a horizontal accuracy assessment
  • IGIC’s application for $50k to do a 2010 FGDC CAP ROI Case Study was successful. We are doing 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, rural electric coops and other utilities.

New IGI Projects

  • 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. County color mosaics are currently being delivered and becoming available on the NRGIS library. 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, started fall 2010, 2 staff persons hired.
  • 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. Will contract with ISU GIS facility for service bureau staff. Project to start January 2011.
  • DNR is working with the Iowa Dept of Education and UI Geography Dept to published updated school district boundaries on the NRGIS library. IDE has contracted with UI Geography to update school boundaries and perform other analysis. School boundaries should be available by the end of the 2010.

IGI Outreach

  • 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. Online mapping application was made available at the end of June.
  • 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. 99% of the state is available now at the USGS Map Store Copy will be available on IGI website by Jan 2011.
  • Rebuild Iowa Office (RIO) is recommending creation of a state office of planning and GIS (OPGIS) to help various groups perform “smart planning” efforts.

Possible Future Projects

  • Applying for 2011 FGDC CAP grant for metadata training, $25k. Emphasis on creating metadata for IGI framework data layers including county GIS files on ICIT Data Repository, and state agencies data layers.

Projects looking for funding

  • NHD attribute conflation on lidar-derived stream network.
  • Geocoding Phase 2 – address points for 50 or so remaining counties, applied for PT funding in July 2010, for July 2011 project continuation. Project rated 4th on list, should happen if legislature appropriates funding for PT account next spring.
  • County GIS Service Bureau – 4 FTEs requiring about $300k per year of ongoing funding



If you have any relevant progress on statewide or local framework data layers, web services, training or coordination efforts to add to this list, please contact me at james.giglierano@dnr.iowa.gov


Next update in January 2011
