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 are complete and stored in county folders on NRGIS Library. Some reflights are supposedly happening.
  • 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 the first goal - we are using a US Postal Service address validation tool to correct and find errors, which is turning out to be a bigger job than previously thought. Planning to get 25 counties out this spring.
    • Contract with ISU GIS facility for address points and structure points for 15 counties by December 2010, work completed with some funds left, contract extended to next June - 10 students worked this past summer, will have a new contract for 2nd year soon.
    • 2 ft contour shape files, 3 meter DEMs and 1 meter hill shades created from lidar for all 99 counties, look in the county directories
    • Last spring, DNR has called all 99 counties to inventory basic framework data layers, with results stored in Ramona tool. The county inventory can be viewed on Google docs. County folks are urged to update their line in the spreadsheet.
    • 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.
    • 3rd Crowdsourcing event will likely be in May 2011, probably in either Fremont, Ringgold or Osceola Counties. We will collect address information using geotagged photos in one of those counties.
  • 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 and web services on the ISU Ortho Server..
    • 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. Project is currently moving slowly.


New IGI Projects

  • 2010 NAIP 1 meter color was flown again this past summer with federal funding. Iowa partners are contributing an additional $91k for 4th infrared band. County color mosaics are currently available on the NRGIS library and ISU Ortho Server. 4-band DOQQ were deliverd in December, will be available soon on the IGI ftp server. We will not be participating in the 2011 buy-up.
  • 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, working on Story County pilot.
  • 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 to start a state agency GIS service bureau - awarded $350k, but got cut back to $302k. DNR is contracting with ISU GISSRF for two GIS service bureau staff to begin work this spring to begin working with state agency GIS projects. Will contract with ISU GIS facility for service bureau staff. Project to start March 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.

IGI Outreach

  • GIS Day Nov. 17 2010 was hosted by ISU and celebrated the progress of the Iowa Geospatial Infrastructure. Accomplishments and plans for the future will be presented in Ames and on the Web.
  • Earth Day Event on Saturday, April 23, 2011 we are planning a GIS Crowdsourcing Event in Johnson Co, doing trail mapping, probably at the Corps of Engineers Coralviille Reservoir properties. We will use the geotagging methodology developed for the address point mapping last fall. Saturday morning for 2-3 hours, call Jim G if interested.
  • We are planning to develop IGI training workshops for users to get hands-on experience with new lidar elevation derivatives, 2' orthos, address and structure points, and maybe some web services. Looking at a training session in SW Iowa in March (Creston?), a half-day workshop at the IGIC conference in April and another half-day training at the ICIT Mid-year in June.

Related GIS Projects

  • High-resolution land cover for state continues. Contact Pete Kollasch at DNR (pete.kollasch@dnr.iowa.gov)
  • 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. Contact Chris Kahle for details at chris.kahle@dnr.iowa.gov.
  • 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. County based maps in PDF form are now avaiable (beta version).
  • ICIT Data Repository revamped - Currently 23 counties have some data available in the data repository. Cedar County recently added.
  • 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 75% completed. Check availability in the NRGIS library. 1970s and 1980s have been started.
  • USGS completed The National Map US TOPO products for Iowa this past year. 99% of the state is available now at the USGS Map Store Copy will be available on IGI website by March 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. The current form of the bill in the 2011 Iowa Legislature can be viewed.

Possible Future Projects

  • Applied for 2011 FGDC CAP grant for metadata training, $25k, about $30k in match from the Geocoding project. Named the Iowa Metadata Outreach Project or IMOP, the emphasis is on creating metadata for IGI framework data layers including county GIS files on ICIT Data Repository, and state agencies data layers. Project is linked to the Iowa Geocoding project and the State Agency GIS Service Bureau project. Grant funds will be used to hire a metadata training assistant. Metadata records will be loaded on an updated Iowa Geospatial Data Clearinghouse, using Geoportal Technology. Four workshops planned, three targeted to specific data producer communities, one for the general GIS community. Maybe we will know if funding is available in February or March, with a June 1 start.

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 April 2011

Eric Abrams contributed this info about DOT's Geonexus Project.

DOT has connection with DAS Data Power Box and will be putting some time wrapping the DOT test environment. Patrick and I will be getting together January 20th to compare notes. Once test is done DOT will determine what mapping and LRS services to expose.

DOT is equipping snow plows with GPS. Eventually plow locations and data will be exposed to DPS through the MACH system.

On Jan 13th, the DOT rolled out our new arc GIS server environment. This new architecture will help complete DOT’s portion of IGI.
