Ongoing IGI Framework Data Projects
- Statewide Lidar Project – 47k sq miles collected out of 57k were collected last spring but many areas have to be reflown – new deliveries started in Sept but not all areas are available from spring 2009. 2010 flights and reflights have started in NE Iowa and east central Iowa
- Geocoding Project – to create address points for 50 counties using $650k from pooled technology fund
- address points for 3 counties in review – Story, Decatur and Osceola
- started production of address point layers for Emmet, Cherokee, Warren, Pottawattamie, Hardin, and Sioux Counties.
- Contract with ISU GIS facility for address points for 15 additional counties by December 2010
- Contract with Geocomm to get E911 data from county dispatch systems
- Possible contract with ICIT for data repository intern to help collect parcel data
- Contour shape files, 3 meter DEMs and 1 meter hill shades were created as by-products, and are available on the NRGIS library for 43 counties – Adams, Allamakee, Appanoose, Boone*, Bremer*, Buchanan’, Cass, Chickasaw, Clarke, Davis, Decatur, Delaware*, Emmet*, Fayette*, Fremont, Howard, Iowa, Jasper, Jefferson, Johnson*, Jones*, Keokuk, Lucas, Lyon, Madison, Mahaska, Marion, Marshall, Monroe, O’Brien, Osceola, Page, Polk, Poweshiek, Ringgold, Sioux, Story, Taylor, Union, Van Buren*, Wapello, Warren, Wayne, Winneshiek (* = partial counties)
- ISU GIS is setting up an ftp distribution point for IGI files which should be ready this summer – will include orthos in state plane from the 2′ statewide project, 2′ contours and other data
- DNR is calling county GIS coordinators to inventory basic framework data layers, with results eventually stored in Ramona tool http://ia.gisinventory.net/ (http://ia NULL.gisinventory NULL.net/)
- Collection of the 2010 2’ 4-band orthos for eastern 41 counties has started. Three counties exercised buy-up option: Des Moines, Lee and Wapello. Parts of Jackson County will also be done at higher resolution. Delivery of 2′ orthos will begin later this summer.
- Dan Corbin, Inc. will again provide 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 a 2010 FGDC CAP ROI Case Study Grant was successful ($50k). 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 – added emphasis on economic development. GITA will again be our major partner in this project. Should commence in June or July.
2010 NAIP 1 meter color will be flown again with federal funding. Iowa partners will contribute 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 using geocoding products for 10 counties in central Iowa $25k, start this 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.
- ROI presentations at MAGIC Conference April 18-22, 2010 Kansas City
- 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.
- ARRA Broadband Mapping – Iowa Utility Board contracted with Connected Nation to map broadband availability in Iowa http://broadband.iowa.gov/board_information/docs/Connect-Iowa-Presentation-10.02.2009.pdf (http://broadband NULL.iowa NULL.gov/board_information/docs/Connect-Iowa-Presentation-10 NULL.02 NULL.2009 NULL.pdf) Data will be delivered in at the end of May 2010, basically census block group level info.
- Iowa state agency projects – assistance to IDPS Fusion Center and State Police dispatch software upgrade, with data and web services from DOT, DNR and HLSEM.
- 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
- ICIT Data Repository revamped – https://www.iowagisdata.org/ (https://www NULL.iowagisdata NULL.org/) Currently 19 counties have some data available in the data repository.
- DNR completed this past 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 50% complete. Check availability in the NRGIS library.
- USGS is currently producing The National Map products for Iowa this year. Should be available by next January. Check here for status: http://nationalmap.gov/ustopo/about.html#status (http://nationalmap NULL.gov/ustopo/about NULL.html#status)
- Pooled Technology Application for 2 FTEs for 2 years to start a state GIS service bureau – rated 3rd out of all PT projects. Funding was allocated by legislature for PT, but status is unknown due to state IT consolidation bill.
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.
Projects looking for funding
- Hydrography 1) high resolution stream centerlines extracted from lidar DEMs for floodplain mapping work 2) 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
