Illegal dumping, embankments, burnt areas, watercourses: surveyed, measured and dated in a format your GIS reads.
Land changes faster than mapping. A flight returns the state of things on the day it was flown: georeferenced, measurable and reopenable in two years to say exactly what has changed.
Figures for this sector
Area occupied, estimated pile volume, access tracks: all measured on the orthophoto, with date and coordinates that hold up in a formal report.
A heap right up against the houses: area, volume and access measured, with date and coordinates.
Surveys repeated over the same perimeter: erosion, slips and scour become measurable differences between two terrain models.
A watercourse loaded after the flood: erosion and scour compared against the previous survey.
Perimeter of the burnt area mapped right after the event, in a format the authority's GIS opens without conversion.
A burnt slope: the perimeter is closed right after the event, in the format the authority opens without conversion.
Counts and censuses on the high-resolution orthophoto; the thermal camera separates an animal from the background when a temperature difference exists — at night almost always, in full sun almost never.
Riparian strip and woodland: counts are made on the orthophoto, where every canopy stays where it was.
