Will County is bordered by Cook, DuPage, Kendall, Grundy and Kankakee counties in Illinois, and Lake County in Indiana. The latest Census projection estimates Will County’s population as just under 691,000. Will County is 849 square miles where just over 12 square miles is not land based. Our project area will consist of approximately 887 square miles as referenced by the county buffer polygon.
Will County agencies that will directly benefit from this effort to acquire LiDAR include the Information, Communication, & Technology (ICT) Department, 9-1-1, Assessor’s Office, Board of Review, Geographic Information Systems Division, Division of Transportation, Emergency Management Agency (EMA), Land Use Department, Forest Preserve District, Health Department, and Sheriff. As part of Will County’s ongoing regional collaborative presence, external agencies and the general public will also realize benefits and access to this data as well. |

<DIV STYLE="text-align:Left;"><DIV><P><SPAN>The Will County, IL lidar project area covers approximately 887 square miles. The lidar data was acquired at an aggregate nominal point density (ANPD) of 10. Project specifications are based on Will County requirements. The data was developed based on a horizontal projection/datum of NAD83(2011) / Illinois State Plane East Zone (ftUS) (EPSG Code: 3435), and vertical datum of NAVD88 - Geoid18 (US Survey Feet)--ISGS comment: all the data uses Geoid 18--. LiDAR data was acquired using a Optech Galaxy T2000 sensor from March 29, 2021 to April, 13, 2021 in 8 total lifts. Acquisition occurred with leaves absent from deciduous trees, when no snow was present on the ground, and with rivers at or below normal levels. Note: ISGS QAQC review found that there are numerous noise points on the DSM, making that DSM unusable in some areas.</SPAN></P></DIV></DIV> |
