GIS Manager Named One of XYHT's 40 Under 40

Dec. 1, 2015 -- Cook County GIS Manager Amber Knapp was named one of XYHT Magazine's 40 Under 40. Amber Knapp is in charge of one of the largest GIS enterprises in the U.S.—Cook County, Illinois, which encompasses much of the megalopolis of Chicago—where she’s overseen the launch of comprehensive GIS apps that provide a variety of information to residents and municipalities, such as Connect to Cook.

Before coming to Cook County, Knapp was the GIS manager of Montgomery County, Texas, where her duties included providing 24-hour support during Hurricane Ike and the infamous Tri-County Wildfire of 2011. She also worked with law enforcement agencies using GIS to catch criminals. She is a much-requested speaker for geospatial conferences and events.

Amber graduated from Central Michigan University in 2001 with a triple major: geospatial science, Earth science, and environmental analysis land planning. In her spare time she competes in marathons and triathlons.

County GIS Receives Esri's Special Achievement Award

July 29, 2015 -- Cook County's Department of Geographic Information Systems (GIS) was honored by Esri this week with a Special Achievement in GIS Award for establishing an enterprise approach to GIS which provides a framework for County departments to collect data, share information, collaborate, and conduct cross-departmental analysis.

Cook County Enterprise GIS goes beyond Cook County Government, and extends vertically to other levels of government (federal, state, municipalities), private sector businesses and, most importantly, to the public. Publicly available applications such as: Cook Viewer, Connect to Cook, and Cook County's TIF Viewer provide a wide variety of information to County residents and those who want to visit or do business with Cook county.

"The SAG Awards identify the organizations and people who are using the power of geography to make our world a better place," says Esri president Jack Dangermond, who presented the awards at the 2015 Esri International User Conference in San Diego. "At Esri, we are always deeply inspired by the passion and innovation of our users. They deserve recognition for their invaluable contributions to their communities and the continued evolution of geographic science."

In addition to Cook County GIS, Esri honored more than 170 organizations from around the world and across a variety of industries including agriculture, cartography, climate change, defense and intelligence, economic development, education, government, health and human services, telecommunications, and utilities.

History of Cook County GIS

On an enterprise level beginning in 1997, Cook County has successfully researched, planned, designed and implemented an enterprise GIS with the intention of delivering data to and improving the services of its constituent agencies and moreover, to enhance and streamline the taxpaying public's access to vital information. This established GIS administers and coordinates land-based information across all County agencies utilizing a geography accurately developed from a photogrammetric base, in conjunction with sophisticated information management tools. The GIS is the vehicle that regulates internal data and work flows as regards spatial information, enables the development of higher-level applications, and provides long-term and stable management.

Cook County, including its seat, the City of Chicago, is the most populated county in the State of Illinois and the second most populous county in the United States. It has a population of over 5.2 million (2010 Census) within its 956 square miles situated in Northeastern Illinois. There are over 1.8 million parcels and more than 12,000 centerline miles of roadway contained within its boundaries.

Cook County has a history with GIS dating back to 1987 with the automation of the Cook County Highway Department's road base. Other departments such as Cook County Zoning Board of Appeals, Cook County Clerk Elections, and Cook County Planning were using GIS to accomplish project-specific tasks.

In the mid-1990s an initiative began to automate the Cook County parcel layer in conjunction with an office automation project at the Cook County Assessor's Office. For over three years specifications were discussed that emphasized an enterprise wide collaboration among a wide number of agencies that would utilize the GIS. This activity would culminate in an RFP that was released and awarded in 1998. By 2004, a comprehensive parcel, planimetric, and imagery data repository was completed along with a parcel maintenance application that mirrored the work flow of the Cook County Clerk and Cook County Assessor's offices.

The County has also allowed all constituent municipalities the ability to receive, free of charge, all data pertinent to their respective geography.

The County continually makes significant upgrades to the infrastructure to allow and promote the use of GIS. This includes enhanced servers, networking environment, desktop machines and web map applications.
