MXR-CS-e911n 11/20 Committed to evolving 911 services, NCT9-1-1 sought to improve their mapping products with more comprehensive data. However, they needed an affordable solution that could easily integrate with their system, plus provide the resolution and coverage to scale their region. Ecopia Building Footprints, powered by Maxar delivered on quality and price point. Using our building footprints, the NCT9-1-1 GIS team is able to distinguish building polygons without an address point (is it an addressable location or a barn?) and classify them to determine which structures are larger than a set threshold, giving the team a good indication of building occupancy and building use such as apartments, office suites, etc. While aerial imagery remains a primary component to their mapping validation, NCT9-1-1 is able to quickly identify new developments or unmapped structures and use aerial budgets more cost-efficiently. Additional value An added benefit of working with the building footprints is change management. The GIS team and Addressing Authorities can now compare new footprint data with archived copies to cross-check address point data for improved accuracy. This level of collaborative innovation is expediting work that previously took years, and was oen lacking valuable context that saves time and lives. Building polygons can distinguish office space from building space, as well as identify where in a large building the caller is located. info@maxar.com maxar.com Building footprints Poor quality images like this one can be enhanced with precise building footprint polygons for a more reliable and accurate dataset. "We wanted footprints for dispatch because in many cases the aerial imagery is outdated. With no address, the building footprints enable the call takers to determine if there is a structure at or near the location of the caller. And now, the call takers can also notify responders about the location of the caller inside a large building and give them a better idea of where to access the property." — Rodger Mann 9-1-1 GIS Manager, NCT9-1-1 Actual incident location Subsequent landline call Phase 2 hit (1/3) ~30 sec Phase 2 hit (2/3) ~30 sec Phase 2 hit (3/3) ~30 sec Real 911 Call in NCTCOG, TX (1/22) 15-Year-Old Girl Wounded in School Shooting in Italy, Texas In real incident during pilot period, School Principal called from a landline, verbal dialogue to confirm address, Phase 2 plots all outside of school.
