A drone survey of a cemetery follows a planned flight path at a consistent altitude, capturing overlapping photographs that cover every part of the property. The images are processed through photogrammetry software that stitches them into a single orthorectified map, correcting for the distortion that occurs in any single aerial photograph. The result is a dimensionally accurate image of the entire property that can be measured and mapped against.
CemSites uses the orthorectified output as the base layer for the cemetery's digital map. The accuracy of the drone capture means that plot boundaries drawn on the map align with physical features visible in the image, giving staff and visitors confidence that the map reflects reality.
