Iowa Geospatial Infrastructure Birthday Party

  • IGI is Iowa’s contribution to the NSDI
  • Originated out of a business plan in 2008 (after the flood)
  • IGI: Collecting, organizing, and delivering consistent framework on data.
  • Framework layers
    1. Geodetic Control: county GPS control monuments & NGS benchmarks – Counties & Federal
    2. Ortho Imagery: BW, Color, and CIR orthorectified aerial imagery – Counties, State, & Federal
    3. Administrative Boundaries: city, county, and state boundaries – Cities & Counties
    4. Cadastral data: public land survey section corners, section lines, & parcel boundaries
    5. Transportation: road centerlines, railroads, trails, airports, & waterways – Cities, Counties, & State
    6. Elevation: digital elevation models & contours – State & Federal
    7. Hydrography: rivers & streams, water bodies, & watershed boundaries – State
    8. Address Points – Cities, Counties, & State
    9. Structures: 2D building footprints, bridges, towers – Cities, Counties, & State
  • 2′ orthos for the WHOLE STATE of Iowa!
  • 5 counties that don’t have GIS programs in Iowa! That is IMPRESSIVE! (June 2010)
  • Geocoding Project (Western half FY 2010-11 & Eastern FY 2012-13)
  • 1960’s Historic Ortho Photography Project (as of Nov. 15th) – January/February 2011 all of 1960’s should be done
  • 1950’s Ortho is complete
  • 1980’s Ortho most likely will be next
  • 2010 NAIP RGB (should be ready in a couple days on IDNR, but is on USDA site)
  • 2010 NAIP 4-Band will come as DOQQ’s (Delivered in next 2 months)

9:50-10:15 – Lidar Completion – Jim Giglierano, IDNR
– Includes lidar derivative demo – county based DEMs, hillshades and 2’ contours
– Stream centerline demo
– Floodplain mapping demo

  • WHOLE STATE of Iowa’s Lidar has been COMPLETED! Avail. from UNI server
  • Some using lidar for flood plain mapping
  • Q:Why are we doing this?? A:So we are ready for the next time.
  • “Why do people want frickin contours??????!?!?!?!?!?!?” (Talking about people DEMANDING contours)
  • Iowa Flood Center is creating the flood layers… (Received $10 Mil from Iowa Gov’t to start creating shp files)

10:15-10:45 – Statewide ortho completion – Andy Asell, IDNR
– 4-band 2’ spring and 4-band NAIP 2010 demo
– Historical aerial photography demo
– High-resolution land cover demo

  • Terrago (Toolbars & Resources)
  • Must use Acrobat to unlock layers
  • 3-D Geopdf
  • import geomarks
  • Can’t do Animations w/ Geopdfs… yet

10:45-11:15 – Statewide Geocoding Project update – Zeb Squires and Evan Koester, IDNR
– Demo of address point collection process

  • Over 1/2 Million Points placed so far! (A little under-half done)
  • Pick up on shadows & use to classify
  • Doing this ALL by hand! WOW!
  • Future: maintained w/ next generation 911 system or county guys maintain

– GPS crowd-sourcing demo – Tyler Johnson

  • Fun, inexpensive solution to collect address data for the geocoding project
    • Take pics or notes of houses
  • Crowd-sourced counties (Completed)
    • Adair County (greenfield)
    • Ida County (Ida Grove, Holstein, Battle Creek, Galva, Arthur)
  • Equipment
    • Camera (res not to big, not to small)
    • GPS w/ track capability (track every 5 sec)
    • Clipboard (papermap w/ assigned route)
  • Data collection
    • Carried GPS & photographed buildings
    • Captured the address & building function
  • Transfering
    • EasyGPS
    • Photo program
  • Used GPS Photo Link (Bought a license, since it worked good for them.)
  • Couple hours of Post Proc.

11:15 – 12:00 – Web services
– DOT transportation web services – Matt Rohlf, IDOT

  • All services are internal (for now)
  • GeoNexus
    • ArcGIS Server 9.3.1
    • Uses esri flex api
  • Jetfire
  • Demos Apps
    • Lidar finder
    • Imagery finder
  • Future
    • Geonexus
      • ArcGIS Server 10
    • “Flat” architecture
      • Improved performance
      • Improved redundancy/failover
      • Reduce servers
    • Exposing jetfire services through datapower SOA State of Iowa App

– Elevation services and NRGIS Library – Casey Kohrt, IDNR

– ISU Orthoserver services, and using ArcGIS Explorer Online – Gregg Hadish, USDA NRCS

  • Iowa GIS Data Repository
  • Server runs on opensource
  • You can request access to view/download files, and the administrator will approve/deny request
  • Used in 08 floods
  • Good redundancy in emergencies
