Software and tools

FieldWork on a computer and a phone: the dashboard with a tree inventory, planting beds, paths and punch list items over a georeferenced planting plan, and a phone showing tree T-114's record

Client tool

FieldWork

A field data app for landscape architects. Record tree inventories, planting beds, punch lists and site observations on your phone during site visits, right on top of the project's own site plans, with or without signal.

It runs as an Android and iPhone app or straight from the browser. Records, photos and plans stay on the phone and sync when there's signal, and an offline edit is never silently overwritten. Data goes back out as DXF for CAD, Shapefile, GeoJSON and CSV, as site visit reports and as read-only client links.

Sign-in required. Screenshots show a sample project.

Work with me

How a project works

I work directly with agencies, nonprofits and design firms, and as a subconsultant on larger teams.

  1. 01

    Intro call

    A short call about the place, the audience, the data you have and the schedule.

  2. 02

    Scope and quote

    A written scope with deliverables, schedule and a fixed fee.

  3. 03

    Drafts and review

    Base map and design drafts, reviewed with your team and revised.

  4. 04

    Final files

    Print-ready files, web maps or 3D assets, and the GIS data where agreed.

What I make

  • Park, trail and recreation maps
  • Interpretive panels and trailhead kiosks
  • 3D and illustrated views
  • Interactive web maps and story maps
  • Planning, site analysis and base maps
  • Exhibit, wall and print maps

Small maps usually take a few weeks. Map series, signage packages and interactive maps usually take one to three months.
