Platform
Everything you need
to draw on a real parcel.
Stratum pulls a Boston property onto the canvas with its real lot lines and zoning data, then gives you the drafting tools to work on it in real-world feet.
Parcel import by address
Type a Boston address and Stratum draws that property's real lot lines on the canvas, with zoning data and setbacks from the city record. One click; no survey upload required.
Sketching on the parcel
Draw directly on the imported parcel — building footprints, massing studies, notes. Lines snap to the lot and measurements read in real-world feet.
PDF import
Drop a PDF of a sheet, survey, or report into the project. Pages render on the canvas and in the viewer tab; you work from the real document, not screenshots.
Image scaling to real-world scale
Scale any imported image to real-world dimensions by drawing one calibration line. Every measurement on top of it reads in feet, correctly, every time.
Infinite canvas
Arrange parcels, sketches, PDFs, and images on an unlimited spatial board. Pan, zoom, and organize by project phase or discipline.
