County & Municipal Cooperation Cost Sharing of Data & GIS Iowa County, City of Dodgeville, Village of Avoca, Village of Highland

Statistics v County Population 2000 Census - 22,780 v 2 Cities and 13 Villages and 14 Towns v Largest City - Dodgeville - Population 4,220 v 21 Supervisory Districts v Economic Base - Farming/Agricultural, Tourism - House on the Rock, Pendarvis House, Rustic Scenery, Governor Dodge State Park, Blackhawk Lake v Businesses - Land’s End, Walnut Hollow, Silicon Sensors, Nelson Muffler

History v Southwest Consortium was created to obtain grant funds for 7 counties to begin their Land Records Program. Orthophotography and equipment were purchased from the Consortium Grant. Thus initiating the County’s whole cost sharing philosophy! v Iowa County Land Records Program began in v Iowa County Land Records Committee and County Board determined the need for Land Records and developed a budget for Land Records which included staff, equipment, & supplies. v The Iowa County Land Records Modernization Plan was developed which showed dedication to Land Records, WLIA, and a development of a GIS System.

History Cont. v A Pilot area including 18 sections in the Southwest region of the County was contracted out in v Iowa County hired it’s first full time employee to develop and maintain the Iowa County Land Records - GIS Technician v With the use of interns and LTE’s Iowa County completed rural parcel mapping within 3 years and completed mapping of Cities and Villages with a year after that. Wha-La! We had Data and something to Show the local Municipalities

Goals v Keep the Momentum Going! v Obtain recent orthophotography v Develop GIS System v Get it to the County Departments v Get it to the local Muncipalities v Eventually, get it to the Public v Become Data Junkies, get more data, the more the better!

Problems v Budget Contraints v Establishing Need for Orthophotography update and GIS System v How to get more data

Orthophotography Plan v Utilize 2002 Grant funds to obtain 2002 Orthophotography. v Fly both High Flight and Low flight orthophotography v Develop both high and low at lower resolution than the original 1995 flight - 18 inch pixels for high flight and 6’ pixels for low flight v Request local municipalities contribute by targeting their municipality in preparation of low flight v Keep low flight negative in the ‘box’ until each municipality is wants to pay for having them ortho- rectified.

Orthophotography Plan Cont. v Request municipalities to share low flight orthophotos with the County in return for the County covering: Targeting costs – High flight & some low flight$ 5,775 Aerial photography – High & Low flight$15,195 Digital ortho-rectification - High flight$36,540 $57,510 Total costs for Iowa County$57,510 v Cost to Municipalities to digital ortho-rectify low flights: v Villages - $1,800 - $3,700 each, dependant on number of tiles & size - 13 Villages total v Cities - $5,500 - $6,000 each, dependant on number of tiles & size - 2 Cities Total

Implementation of Orthophotography Plan v Held a “Foto-Fly 2002” Open house and invited Municipalities to attend. v Explained the Cost sharing and benefits to each municipality v Received help from Ayres in demonstration and providing cost quotes for each municipality

Project Outcome v County received updated orthophotography with higher resolution at 40% cost savings compared to the original 1995 flight. Mostly due to changes in technology and maintaining original DTM. v County obtained updated low flight orthophotography from 2 Villages and 1 City. v Village of Avoca - purchased and contributed their low flight orthophotography. Purchase price - $2,630 v Village of Highland - purchased and contributed their low flight orthophotography. Purchase price - $2,100 v City of Dodgeville - purchased and contributed their low flight orthophotography and also contracted Ayres to develop DTM’s with 2 foot contours. Purchase price - $6,000 orthophotgraphy & an additional $14,000 for new DTM with 2 foot contours.

Project Outcome Cont. v Standing offer for all other local municipalities to purchase low flights and share with County. v Periodical contacts from Ayres and the County to help local municipalities understand and realize the potential of the orthophotography and cost savings and benefits. v Improvement on accuracy of the Municipality parcel mapping due to higher resolution orthophotography.

GIS Website Plan v Implement Web-based GIS v Service over web to eliminate need for multiple software licenses using ArcIMS v Add County data: parcel data, orthophotgraphy, topographic raster images, soils, road centerlines, etc. v Allow County departments to access the information immediately with the use of user name and password. v Allow local municipalities to access website with use of user name and password. v Eventually establish a public access site which withholds personally identifiable information without the use of a user name and password.

GIS Website Plan Cont. v Expand Web-based GIS v Place municipality purchased low flights on website on behalf of participating Municipalities. v Offer Municipalities to add their data to our website for simply the cost of installing in onto our existing ArcIMS website at a cost of $75-$100 per layer. v Offer Municipalities the option of ‘locking off’ their data from the public or others so that only they have access to their data from our site. v Cover the cost of installing regional data onto the site: data that covers the entire county such as wetlands, MFL, topography, mining, etc.

Implementstion of GIS Website v Contracted with Ruekert-Mielke to design and implement Iowa County GIS Website using ArcIMS v Attended every Muncipality’s Board Meeting and demonstrated the functionality and uses for the GIS website and how it would benefit them. v Gave each Municipality a user name and password for access. Allowed access free of charge. v Offered each Municipality to add data at any time.

GIS Website Outcome v Test ran the site internally and with Municipalities for about a year. v Provided Training to each Municipality and Department on how to use the system v Initiated ‘Public Access’ site on December 31, Municipalities aided in notifying the public of the website by adding the GIS brochure to the tax bills being sent out. v Obtained data from Village of Highland: water, sewer, zoning and land use. Installed onto website. By request of Village of Highland, locked off these layers from the public access site. v County updates parcel mapping at least once a year.

GIS Website Outcome Cont. v Continuous input is being received from municipalities in order to improve the system or correct errors in the data supplied on the website such as unknown parcel owners, parcel addresses, road names, etc. v Increasing number of hits on the website every day. Calls from public concerning errors in the data. v Increasing number of people inquiring about how to use the site. v Decrease time spent on special order maps since we can refer customers to the website which allows them to print their own maps.

Summary of Benefits For both projects, the County benefited by substantial cost savings. v We were able to obtain low flight orthophotos without purchasing them ourselves v We were able to save money on targeting for the orthophotography since local municipalities targeted in there region. v We will eventually save money as these municipalities add their data to our website. Data which we will not have to develop. v We formed an alliance for future projects

Summary of Benefits Cont. For both projects, the Municipalities benefited by substantial cost savings. v They were able to obtain low flight orthophotos without incurring the high costs of the airplane flight and negatives. v We were able to save money on targeting for the orthophotography since the County targeted in nearby regions. v They have access to all the County’s data as well as the option to add their data for very little cost. v They were able to access the County’s GIS without incurring software licenses. v They formed an alliance for future projects and realize the County’s efforts to help provide them with useful information with little cost to them.

Wish List for the Future v Create a complete County-wide GIS website with all Municipalities adding their data. v Continue with Cost sharing for future orthophotography project - next one being in v Continue to use these cost sharing ideas on future projects so that users of land and spatial information data will be able to get more bang for the buck.
