[May 29, 2012]  Logan County's Geographic Information System coordinator, Will D'Andrea, has just completed upgrades to the county's GIS. D'Andrea came before the Logan County Board this month to give a brief explanation of the expanded and redesigned mapping site. This was a follow-up to a demonstration that he promised six months ago when he said major upgrades were in the works that would greatly improve the site.

D'Andrea was pleased to announce the completion of the "redesign, revised and expanded GIS mapping site." The new tools are available for those who are looking to find information about properties in Logan County. Any computer user can view the dozens of mapping layers that have been created over the past few years. No special software is required. He said there are about a dozen new features running on the site now.

D'Andrea then quickly demonstrated a few of those.

The site is readily findable anytime for anyone by going to the Logan County website, http://www.co.logan.il.us/. Choose "GIS" from the bar at the left side and then "Internet Mapping."

You may want to open your browser to the site now and follow along at http://www.centralilmaps.com/LoganGIS/.

On the right-hand side:

There are several navigation tools you will use for zooming in and out of the big picture, panning, moving screens, and also for zooming in and out of different scales in order to get closer to whatever property you want to look at.

It might take a little practice to get acquainted with these, and you will learn that you will need to allow a moment for some of the tools to respond.

Going to the top toolbar:

Across the top toolbar you will see eight icons that offer:

  • The ability to identify parcels by number as well as find owner information on a particular property.

  • An enhanced search for information, allowing you to look for a property by address.

  • Expanded drawing and measuring tools that help calculate acreage or distances.

  • Buffering tools to help you to find a particular distance or point from a property, such as 200 or 500 feet away.

  • The street view feature is a Google view. With this you can see what the property looks like at the street level and pan around.

To the left side you will find the overlay options:

Each of these overlays also has sublayers you can choose. Where you find a plus button (+), click, and it opens additional layers. You can keep all the layers on once you turn them on, or you can turn them off as preferred.

The primary overlay sections are Transportation, Environmental, Political, Property, Tax Districts, Miscellaneous GIS Data, Aerials. Below is an abbreviated review.

  • Under transportation you'll get highways, streets, roads and railways.

  • Environmental has flood plain, soils, waterways.

  • Property shows parcel boundaries, addresses for rural areas, structures, driveways and more. Every subdivision is now recorded, color-coded and labeled. This is a great feature that is good for property research.

  • Political shows city, village and township boundaries. Precincts have been added.

  • Tax districts provide a lot of useful information with a quick click. Using these tools gives you quick information on school, drainage, library, park, voting and TIF districts.

The addition of K-12 schools and all the colleges in Logan County is new, as is the precincts layer.

Did you know that we have three TIF districts in the county: Mount Pulaski, Elkhart and Atlanta? Turning that on, you can go in and see which parcels are in the TIF districts.

These tools are great for potential homebuyers and businesses with specific needs when they want to buy, rent or lease property.

"So, all that is available just at the click of a button now," D'Andrea noted.

Under miscellaneous data, there is a category just for wind farms. Rail Splitter is in place, and room has been left for Sugar Creek. Precise tower locations are shown. Survey data for the control points, sections and township range can be turned on and off.

Another important layer that took considerable effort is zoning. The default layer is for unincorporated areas of the county. Additionally, it is also available for the communities of San Jose and Hartsburg.

"I'm also working with other municipalities to get their (zoning) layers on as well," D'Andrea said. "This is parcel-specific parcel zoning,"

Something new that is of special interest is the historical data that has been added. D'Andrea went to the Illinois Department of Transportation site and found aerial photography of all the populated areas, going all the way back to 1940. "I thought it was kind of fun," he said.

He also found some original township plat maps from the 1800s. Combining the plat maps with different years of aerial photography, "you can see how things looked and changed and compare to today's parcel layouts."

The above information was delivered in about a 10-minute introductory session. D'Andrea explained that he took an hour showing the site to the Logan County Regional Planning Commission earlier this month. He would welcome sitting down with others who would like to see more about how to use the site.

There are many uses for the GIS system for both governmental agencies and the private sector. You are welcome to contact D'Andrea to explore the possibility of adding layers or how to use what is already in the system.

The GIS committee has regularly hosted an open house with demonstrations each year in November.

Several board members commented on their appreciation of what D'Andrea has accomplished and uses of the site:

The finance chairman, Chuck Ruben, who is a hog farmer and staunchly anti-computer, complimented D'Andrea.

"This has been a lot of hard work for Will," Ruben said. He added: "You'd be amazed at all the information on this (site). I know you guys are going to find this hard to believe -- I've even pulled this up on the computer and looked at it a little bit."

In response, there was a genuine-sounding "Wow!" and laughter through the room.

Sally Litterly, county clerk and recorder, said her office has a lot of searchers who come in and use that feature now.

Kevin Bateman said, "It's nice when you want to buy a house." He particularly likes looking for rental property. He said that when checking real estate that is available, "you can find the address, zoom in on it, see the boundary lines and what it looks like before you even go look at it."

Litterly added that with subdivisions added, you can now find out which school districts the property would be in.

D'Andrea can be contacted at the Logan County Zoning Office, 529 S. McLean St., Lincoln, IL 62656; or by calling 217-732-8835.
