Bannock County GIS manager updates commissioners on 911 work, imagery and data projects
Summary
GIS manager Heather Sedley briefed the commissioners on work to support next‑generation 911 services, recent EagleView imagery collection, mapping for public works, and efforts to align address data with elections and neighboring counties.
Heather Sedley, Bannock County GIS manager, told commissioners on June 17 that her office has nearly completed the initial mapping and data creation for a mapping application Public Works is implementing and that day‑to‑day GIS work focuses on addresses, subdivisions, records of survey and new roads.
Sedley said the GIS team is engaged on two parts of 911 work: ongoing coordination with the county’s Motorola contractor to keep the 911 system current (addresses, roads, boundary changes) and preparations for NextGen 911 core services. She said the county held a meeting about NextGen core services the prior week and is working to make sure boundary lines and datasets align with state requirements.
Sedley reported an EagleView/Pictometry aerial imagery flight had just been completed; product delivery is expected in about two months and the county will distribute the dataset to partner agencies once received. She said the GIS office also participates in state geospatial committees and a national Geospatial Professional Network, and described community outreach including a geocaching event for middle and high school students at ISU’s STEM day.
On addressing, Sedley described the county’s address-assignment process: addresses are usually issued when building permits are submitted, take 20–40 minutes in routine cases, and follow a grid system that assigns roughly 1,000 addresses per mile from a defined origin point. She said roughly 80% of addresses are straightforward; the remaining 20% can take days when complicated.
Sedley said the county’s address database is authoritative for local operations but that third-party mapping providers do not always update from county data. She noted county efforts to improve data sharing with nearby cities (including Pocatello and Chubbock) and work to help Power County with their 911 data.
Commissioners asked about timelines for address updates and background imagery refresh rates; Sedley said background imagery refreshes vary by vendor and that rural areas see longer delays. She said the county is trying to align elections address data with the county database so voterregistration addresses will appear correctly.
No formal actions were taken; the presentation was an informational departmental update.
