UAV Change detection using FME and QGIS
summary
Automated workflow uses FME automation to compare yesterday’s base DEM with each new UAV flight over a 10‑hectare site flown daily for six months, producing a 2 cm grid cut/fill raster; noisy objects (vehicles, containers, ponds) are removed by operators using QGIS digitize and then zonal statistics sum the raster cells. Volume calculation multiplies the cell-value sum by (0.02 m)^2 to generate daily cut/fill reports and JPEG time‑lapse images.
