Aerial Services Inc, has two articles about “flood” imagery taken by ASI after the 12-15” rain in Dubuque County last summer:
Iowa 4-H and GIS
David Runneals (david@runneals.com)
AMES, Iowa – Teenage 4-H scientists say they are “restoring something old with something new.” The something old is a bur oak savannah in the Neal Smith National Wildlife Refuge. The something new is geographic information systems (GIS) mapping using mobile phones.
The
Iowa 4-H’ers are one of four teams of 4-H members in four states that
are carrying out GIS mapping with national wildlife refuges, fish
hatcheries or other ecological services offices, said Jay Staker,
director of Iowa State University Extension Science, Engineering and
Technology (E-SET). ISU Extension is leading the effort with the
National Institute of Food and Agriculture (USDA NIFA) and the U.S. Fish
and Wildlife Service. Kansas, Minnesota and New York also are involved
in the project. The four states are sharing the $73,000 U.S. Fish and
Wildlife Service grant that funds the effort.
The
U.S. Fish and Wildlife Service has stated that GIS soon will become so
prevalent in natural resources management that organizations without
some GIS capability will be at a severe disadvantage.
Karen
Viste-Sparkman, a wildlife biologist at Neal Smith National Wildlife
Refuge, was glad to receive the call from Staker. “He was working with
4-H groups and they had a grant to work on a national wildlife refuge.
We got excited about it because they wanted to do GIS work … and that’s
one of the things we really need more of here,” Viste-Sparkman said.
The
Iowa 4-H’ers are using GIS on iPhones to map the locations of remnant
bur oak and shagbark hickory trees that have been invaded by exotic
non-fire tolerant trees in the wildlife refuge.
“We
have an iPhone app that talks with the ISU GIS department server, so we
get real-time interaction,” said 4-H Tech Team member David Runneals.
“What’s cool about this project is we actually get to use technology and
that we also get out in the field to get experience.”
Volunteer
4-H leader Debbie Stevens noted the need for GIS, “but a lot of folks,
especially nonprofits or governmental entities cannot afford to just
hire someone. Our youth in 4-H are learning real world skills. This is a
professional-level occupation now. … So not only are they having fun,
they’re gaining knowledge, they’re learning technology skills,
information management and personal development for future careers.”
The
4-H’ers will continue to do GIS mapping over the summer months to
identify the locations of as many bur oaks, hickories and other species
as possible, Stevens said. Then in the winter months when the ground is
frozen, the refuge staff can do maintenance, removing dead or diseased
trees as well as trees that don’t belong in a bur oak savannah.
“This
GIS mapping project engages 4-H youth as citizen scientists to conduct
relevant research that will have an impact for both the Fish and
Wildlife Service and the 4-H’ers,” Staker said. “The Fish and Wildlife
Service gets data for habitat protection, conservation, restoration and
other uses. The youth get opportunities to serve their states with
meaningful research. They also develop skills that could lead them to
pursue degrees and careers such as wildlife biology, natural resource
management, science, community planning, recreation or agriculture.”

IGIC Public Health Committee
Simon Geletta (Simon.Geletta@dmu.edu)
The
IGIC health committee has a new member - Ms. Meghan Harris who is
Executive Officer II - Data Warehouse Coordinator at the Iowa Dept of
Public Health (IDPH). We hope to hold a teleconference to do some
planning this coming November.
Des Moines Area Regional GIS
Anna Whipple [awwhipple@dmgov.org]
The
City of Des Moines recently completed enhancements to the Des Moines
Area Regional Geographic Information System (GIS) to support hazard
identification and risk assessment. The Regional GIS participants
included Polk County, Des Moines, and several Des Moines suburbs, and
the project was funded in part through a FEMA subgrant. A consultant
team from Indiana University, University of Iowa, and University of
Northern Iowa was hired to assess local GIS data, to map hazards and
assets in the region, and to develop a GIS-based
methodology for modeling vulnerability and estimated losses from hazards. The consultants and Regional GIS participants:
• Developed quality local GIS data for buildings, infrastructure, facilities, and populations exposed to potential hazards
•
Deployed and trained on HAZUS-MH, FEMA’s standard GIS software
for hazard risk assessment, and other applicable GIS analysis methods
• Created processes for updating regional asset data from many sources and packaging the data in a HAZUS-ready format
HUD Grant Ideas
Herb Kuehne [hkuehne@cableone.net]
Several
weeks ago, Jim Giglierano invited me to help him write a HUD grant that
would enable IGIC to assist 16 southeastern Iowa counties in assembling
a battery of GIS data that could be used for community development
planning in the region. Jim decided that we didn’t have time to write
the grant, but the idea got me started exploring other ways that IGIC
might seek grant money. Health care is huge preoccupation in our
culture (who wants to die?) and ways to deliver it more effectively
would probably be of interest to grant-funding organizations. I’m
currently researching about how IGIC might propose GIS work that would
provide geographic data important for suggesting ways to deliver health
care more effectively. Collecting extensive geocoded data on
residences, medical care facilities, pharmacies, grocery stores, and
lots of 2010 demographic data might provide the kind of information that
could then be analyzed. I sometimes feel that we don’t do enough
“analysis” of the data we collect. Analysis of a complex set of data on
something like rural health care delivery might really show why GIS is
such a powerful tool….and why IGIC is such a great group of people, too!
Low Distortion Projections
Roger Patocka [patocka32@yourstarnet.net]
The
State Land Surveyors of Iowa and the IDOT group working on LDP’s
apparently reached a consensus that a 20 ppm (1:50,000) distortion
design is acceptable as long as ten to twelve zones could be developed
to cover the state.
This
means that 20 ppm would be the maximum distortion that would be
expected, however most of the LDP coverages would display less
distortion. Stated differently, most of each zone coverage would have
distortions between 0 to 20ppm (between 1: infinity and 1:50,000)
distortions by design. Distortions of 200 ppm (1:5000) are approximately
1’ per mile. Distortions of 20 ppm (1:50,000) are approximately 0.1’
per mile (or 0.6’ per typical “township,” or 2.4’ per typical “county”).
LDP’s
allow us to be more confident that we only have a maximum distortion of
approximately 2.4’ that is attributable to grid to ground (g/g)
projection across the distance mapped for a typical “county.”
The
goal is to make GIS use more simple. The value of LDP’s will be
realized if we work together to publish and use parameters for these
“standard” projections.
ESRI,
AutoCAD, Microstation and data collector manufacturers likely will
integrate Iowa’s standard LDP zones into their products. This should
allow surveyors and other GIS users to push a button to move from one
projection to another without worrying about excessive distortion of
their map caused by the issue of grid to ground.
Users
of GIS who need precise locations for property boundaries may have
needs to account for distortions beyond the designed 20 ppm LDP.
Typically, as GIS and CAD displays are zoomed in, distortions become
more noticeable. But by establishing datums that provide a 20 ppm
maximum distortion attributable to g/g projection, those users will be
able to develop a better sense of confidence in when these distortions can be ignored for their particular application.
Details
concerning the organizational structure and finding appropriate
resources to support implementation in Iowa will continue to emerge. The
major stakeholders in this endeavor will likely be Professional Land
Surveyors and Engineers, SLSI, ASCE, ISAC, ICEA, IDOT, NGS, IGIC, state
agencies, counties, cities and private enterprise. Have I missed
anyone?
2011 USDA NAIP Imagery and 1980s Historical Orthos
Gregg Hadish - NRCS (Gregg.Hadish@ia.usda.gov)
If you haven't already added it: the 2011 NAIP is available state-wide through the USDA Data Gateway:
http://datagateway.nrcs.usda.gov/ Gregg will be working on getting these on to the Iowa Geographic Map Server soon. http://ortho.gis.iastate.edu/
Also state-wide 1980s CIR image services (ArcGIS and WMS) are available through ISU GIS Facility.

City of Johnston GIS “News-not-worthies”
David Croll [dcroll@ci.johnston.ia.us]
We
have been doing extensive classification of our county’s parcel data
for use in a Stormwater Utility Billing Scheme. A summer intern was
tasked to classify parcels based on Landuse and structures etc. This
will enable us to join parcels to our billing system to appropriately
bill if a stormwater utility goes into effect.
Polk
County Emergency Management has asked the help of the Des Moines Area
Regional GIS participants in implementing a universal Grid for Polk
County. Early suggestions from the GIS constituents is that we will
probably use the U.S. National Grid. Ideally within 6 months we will
have a U.S. National Grid Atlas for all of Polk County in .pdf form at a
couple of different scales. We plan to use ESRI’s Data Driven Pages
functionality in 10.1 to drive semi-automated creation of the Atlas.
Work
continues with the Johnston Police Department on mapping the photos
taken inside schools for the Critical 360 Project using Pictometry
Online. We now have 3 schools photographed and 1 school completely
online within Pictometry Online.
With
2010 Census data available, we have been using those population numbers
to derive populations within Census blocks for emergency planning and
evacuation routes and target marketing for bond referendums.
That’s all from Johnston
Cedar County GIS
Joshua Sales - Cedar County GIS [gis@cedarcounty.org]
We
finally launched our online viewer, which helped put GIS out there a
little more than before. Most response have been positive so far: https://cedar.integritygis.com/
Moreover,
we picked up Spatial Analyst and I have been able to utilize toolboxes
for more advanced analysis. Much of this work has been put online via
ArcGIS Online and the Iowa GIS Data Repository, including forest
morphology and slope position layers. I have been anxiously awaiting
the new DNR land cover to redo the forestry analysis.

State Agency GIS Service Bureau
Evan Koester (Evan.Koester@dnr.iowa.gov) -
(editor’s note, Evan was recently hired to work as the state agency GIS
service bureau, with funding from a State Agency Pooled Technology
grant through December of 2012)
The
Iowa GIS Service Bureau is winding down the initial interviewing
process and is starting to identify and address common GIS related needs
in state government. We have met with several state agencies and a
handful of other state government groups.
Many
users, previously isolated, are already taking advantage of new
interagency relationships, and overall, people have been very receptive
towards efforts to establish an all inclusive clearinghouse of metadata
and/or data. People have started using the GIS Service Bureau resources
to find datasets, develop general or specific GIS skills, get
assistance with data development, and in one case reduced a data
processing timeline from three months to six hours.
Overall the project is growing in a positive direction and looks to be a valuable resource for state government in the future.

2011 NSGIC Annual Conference
The
2011 NSGIC annual focused on many of the same themes as years past.
Collaborative efforts and increased communication on the Next
Generation 911, addressing, and For the Nation (FTN) initiatives are the
leading advocacy items for the upcoming year. The U.S. Census Bureau
discussed increased efforts to partner on addressing with local
governments and is looking for the states to get more involved to help
coordinate.
The
NextGen 911 and Geospatial Preparedness committees were very active
during the meetings. The NextGen 911 group has put together a couple of
informative handouts on NextGen 911 and coordination ideas for the
states. Iowa may be taking part in a NSGIC pilot project for
Stewardship and Maintenance of Critical Infrastructure & Facility
GIS data. There are currently 8 states interested in utilizing
Indiana’s maintenance application to accomplish this pilot.
Voter Geocoding Project
A
unique project that HSEMD is currently working on is the Secretary of
State’s voter geocoding project. There is an obvious need to geocode
all 1.9 million voters ahead of the caucus. We are currently in
discussions regarding the accuracy of the data and their overall
expectations. I have reached out to the DNR and ISU to potentially
become leads on this project if funding is available.
The
Next Generation 911 project for Iowa has begun. There are 5 pilot
counties yet to be determined, we are in the beginning stages of data
collection. ICIT is assisting our efforts and send out a message on
behalf of HSEMD. Data has been received from 20 plus counties.
DOT GIS moving towards asset management
Eric Abrams (Eric.Abrams@dot.iowa.gov)
DOT moving toward asset management philosophy to sustain infrastructure investment. This philosophy asks five core questions
What is the current state of our assets?
What is the required level of service?
Which assets are critical to sustained performance?
What are the best Operations & Maintenance and capital improvement plan strategies?
What is the best ling-term funding strategy?
New
GIMS system will be operational soon and next spring will be the last
time DOT road network will be segmented by multiple attribute
properties. Road data will be dynamically segmented for each 30+
features.
DOT sign inventory is functioning. See Brad C. for information.
DOT asset collection pilot is starting with a vendor. See Shawn B. for information
