The file is a geospatial coordinate system definition (TileIndex.prj) related to a digital orthophotography and LiDAR data acquisition project for Greenville County, South Carolina. The county is soliciting sealed proposals for a one-year contract with four optional annual renewals, covering the 2026 through 2030 flying seasons. The project encompasses 986 square miles, involving 1,100 tiles measuring 5,000' x 5,000', with the primary objective of generating high-resolution geospatial data to detect changes in county building structures and features. Proposals are due on November 14, 2025, at 3:00 pm, with a tentative award date of November 26, 2025, and final orthoimagery and LiDAR data deliveries required by April 15th each contract year.

The project requires vendors to produce natural color digital orthoimagery with six-inch ground resolution in uncompressed TIF/TFW format and LiDAR point cloud data classified according to ASPRS standards in LAS specification 1.4-R15 format. The county will provide 45 ground control points and may participate in statewide orthoimagery projects in 2026 and 2029. Pricing follows a multi-year approach with year-by-year cost submissions from 2026 to 2030, and payment terms include monthly invoicing with a 10% withholding until project completion. The total project price will not exceed the amount specified in Attachment A, and the county reserves the right to terminate the contract if funds are not appropriated in the current or subsequent fiscal years.
