2026 Big Sky GeoCon - From Data to Design

This presentation will focus on the GIS methods and challenges involved in structure surveying and inventory in the Yellowstone River Basin for Montana DNRC for the purpose of updating regulatory floodplain maps and how our GIS team utilized ArcGIS Field Maps to deploy structure and data forms for field crews to reference and collect data in the field. GIS field solutions proved themselves invaluable for daily and long-range planning for this project. Data collected was delivered in FEMA complaint databases comprised of structure location, information, and dimensions for 482 structures and 1446 bathymetric cross sections on 641 miles of river.
