Field notes
The workflow starts with a floor plan in PNG, JPG, or PDF; the page says vector PDFs exported from CAD give the best results. Users can model wall materials and access-point placement, then optionally collect real scans and compare them with predictions using difference maps and statistics. The site lists IDW and kriging for survey interpolation, and provides a SHA-256 checksum for its 23.7 MB Windows download.
