Satellite Takeoff
Draw the clearing boundary on satellite imagery and Mastiff computes the acreage from the geometry — never from a number somebody typed. Split a tract into zones by density, price each one at its own rate, and send the customer the same marked map your crew works from.

The problem
The landowner says five. The appraisal district says eight. You bid five, clear eight, and eat three. Every acre you guess at is margin you're gambling with — and the argument at the end of the job always happens on ground nobody drew a line around.

How it works
Search the address and the map lands on the property. Rural addresses that geocoders miss can be found by dropping straight onto the imagery instead.
Click the boundary of what you're actually clearing — not the parcel line, the work line. Pull vertices around the keep-trees, the stock tank, the pond edge.
Heavy cedar on the front eight, medium brush along the fence: draw them as separate zones and name them. Each carries its own acreage and prices at its own rate.
The marked map rides on the quote the customer approves, the work link the crew opens, and the PDF that gets filed. One drawing, every surface.
Capabilities
Draw the boundary over current imagery of the actual property. What you see is the cedar you're quoting, not a plat drawing from 1994.
Area comes off the polygon with the same spherical-excess math PostGIS uses, rounded to two decimals. The figure that prices the job is derived from the shape, so it can't drift from what you drew.
A tract is rarely one density. Split it, name each zone, and let the rate card price heavy and medium separately instead of averaging your margin away.
A saved quote keeps its acreage even if the formula is tuned later — same reasoning as storing quote totals. Read-back revalidates the numbers against the geometry and refuses a map whose acreage disagrees.
The largest zone's centroid gives the distance to site, so the travel charge is computed from where the work actually is rather than from a guess at the driveway.
One drawing renders everywhere without booting a map: a composed snapshot for the documents, the zone chips and acreage on every surface that shows the job.
FAQ
The area is computed geodesically from the polygon you trace, using the same approximation turf.js and PostGIS use — the error is negligible at parcel scale. The accuracy that matters is how carefully you trace the boundary, which is why you draw the work line rather than the parcel line.
Yes — that's what zones are for. Trace the heavy cedar as one zone and the light brush as another, name them, and each prices at its own per-acre rate. A twelve-acre job that's eight heavy and four medium bids as exactly that.
Yes. The marked map rides on the quote they approve and the tracking portal they follow, and your crew opens the same drawing on the work link. Everyone is looking at one boundary.
For a lot of jobs, no — the takeoff is enough to quote from. Walk it when you need to see what imagery can't show you: ground conditions, access, what's actually under the canopy.
Trace the boundary, let the geometry do the arithmetic, and send the customer a map instead of a number.
