Vastu Plan Tracer

Turn a floor-plan image into the plot.polygon geometry the Vastu API accepts. Your image never leaves this page — it is read in the browser and only the coordinates you review are sent when you choose the sandbox.

There is no scale-calibration step. The API normalises your traced ring onto the real width × length you enter, so the trace only has to carry the shape — raw image pixels are a valid submission.

Local assist works on one clear, closed, axis-aligned outline. It does not read room names, dimensions, or north. Open walls and unclear plans need manual tracing. Maximum file: 8 MB / 16 million pixels.

Load a north-up plan. Choose Suggest outline for a clear, closed outer wall, or click its corners by hand.
Check the dashed suggestion against the image. Use it only if it follows your plot boundary, then drag or edit its points.
Optionally add rooms and trace each one — you get per-room directional occupancy.
Enter the real east–west width and north–south length. Confirm north alignment, then copy the JSON or try it live.

Edit point coordinates

Image pixels: X goes right, Y goes down. Changes affect the selected outline or room.

Directional resolution

I checked that the image top points north. Width and length are real dimensions in the same unit.

POSTs to the keyless sandbox at /sandbox/astrology/vastu/plan/analyze. The sandbox computes from your body within its published limits and never charges.

Coordinates are a local plane in your units: +X east, +Y north, origin anywhere. This page handles the screen-to-north flip for you.
