GIS Data Updates & Maintenance

The City of Edmond, Oklahoma, is seeking a qualified GIS services vendor to update and maintain a wide array of spatial data layers—including parcels, easements, water, wastewater, storm infrastructure, zoning, and fiber—on an ongoing basis as new development occurs, capital projects are completed, and field corrections are identified. The contractor must perform data conversion from hard‑copy or digital plans, conduct high‑accuracy GNSS field surveys (±3 cm horizontal, ±1 ft vertical), verify legal descriptions within 24‑48 hours, and deliver updates in ESRI geodatabase format while preserving critical attribute IDs for integration with the City’s asset‑management systems. The contract is expected to be renewable annually and will involve regular monthly or bi‑monthly data deliveries, with an eight‑week turnaround for each update set, plus optional GIS programming services. • Update and maintain core GIS layers (parcels, easements, water, wastewater, storm, zoning, fiber, annotations, project areas). • Perform field surveys using survey‑grade GNSS equipment to meet ±3 cm horizontal accuracy. • Verify legal descriptions and deliver results within 24‑48 hours of receipt. • Deliver data in ESRI geodatabase format, preserving FacilityID/ObjectID attributes. • Provide a data dictionary, QA/QC documentation, and optional GIS programming support. • Contract term initially one year, renewable annually; anticipated annual budget in the mid‑hundreds of thousands to low millions.
