Eugene, Oregon

Every Oregon ash in Eugene, found before the borer.

For the City of Eugene we mapped 390 acres across 13 designated areas and classified 12,632 crowns, 5,261 of them Oregon ash, at 85 percent accuracy on crowns the model never saw, delivered as hosted products the city's GIS and forestry staff work from. Lane County is where the tree inventory work on this site was proved.

The ground

Eugene and Lane County

Eugene and Springfield sit where the McKenzie meets the Willamette at the south end of the valley, with the Coast Range timber to the west and the Cascades up the McKenzie to the east. The city's urban forest is one of the state's largest, with Oregon ash along every creek and slough, which is why the ash question came here first. The 2020 Holiday Farm fire ran down the McKenzie corridor, and the watershed that feeds the city's water starts there.

Who buys mapping here

  • City of Eugene: Parks and Open Space, Urban Forestry, Public Works, the GIS group
  • City of Springfield and the Willamalane Park and Recreation District
  • Lane County: Parks, Public Works, Emergency Management
  • Eugene Water and Electric Board and its McKenzie watershed program; Springfield Utility Board
  • Lane Council of Governments, which holds the regional GIS
  • McKenzie Watershed Council, Long Tom Watershed Council, McKenzie River Trust
  • University of Oregon and its campus grounds
  • Eugene Springfield Fire and Lane Fire Authority
  • The timber owners and the mills in the Coast Range and up the McKenzie

Getting there

From Medford

About two and three quarter hours up Interstate 5 from Medford. A day trip for a site, a few nights for a citywide flight.

The public lidar

What exists, and what it misses

Lane County has some of the best public lidar in Oregon, flown more than once by the state consortium, and the county and the cities use it well for terrain and floodplain work. What it does not carry is this year's canopy: species, health, crown by crown, in October when the ash gives itself away. That is the flight we add on top of it.

Every service

Everything we do, in Eugene

  • Tree inventory and canopy Start here

    Every crown in a city, a park system or a campus, with height, species and health, checked against trees on the ground.

  • GIS consulting and data Start here

    Hosted data, web maps and dashboards, Survey123 field apps, scripted reporting, and the cleanup of the data you already have.

  • Rivers, riparian and habitat Start here

    Species along a river corridor, wetlands and habitat, cold water seeps found with thermal, and baselines for restoration work.

  • Drone LiDAR

    Bare earth under the canopy, contours, surface and canopy height models, classified point clouds and line corridors, PPK controlled and checked.

  • Forestry

    Stand inventory, species and health classes, downed woody debris counted and measured from the air, post harvest monitoring.

  • Wildfire fuels and CWPP support

    Canopy height, ladder fuels and structure exposure for a Community Wildfire Protection Plan, citywide when the plan needs it.

  • Night infrared on active fires

    Heat perimeters and hotspots in the incident team’s hands before the morning briefing. The pipeline that builds the package runs at the UAS Wildland Fire Collaborative, the nonprofit we founded.

  • Farm planning

    Terrain, drainage low points, slope and sun, canopy, and plan overlays drawn on a current orthomosaic of the whole farm.

  • Property and site design

    Design ready contours, tree points and surface models, in the formats and coordinate system the engineer specifies.

  • Multispectral imaging

    Five calibrated bands, vegetation indices, and species and health classification with its accuracy reported.

  • Thermal infrared

    A calibrated temperature in every pixel, flown as a mapping mission: fire heat classified in degrees, prescribed fire mortality, cold water seeps.

  • Federal and agency work

    Fire infrared, LiDAR on abandoned mine lands and forest data for federal land managers. Registered in SAM.gov.
