Geomorphology is the study of land forms and the different processes which shape them. Environmental assessment is the most common application of geomorphology, namely in the areas of landslide prediction, earthquake prediction, volcanic activity monitoring, and coastal deformation.
Gathering info from the sky has been an approach that’s been utilized for a long time now, but the costs associated with traditional manned aircraft makes the endeavor extremely expensive. UAVs offer a cost effective alternative with far more flexibility in terms of being able to get into the air quickly and without as much logistical support.
Mapping is typically used to portray scaled geographical features forests, roads, and water. It is generally an ongoing process because regular changes in climate conditions and structural developments make it necessary to carry out regular mapping.
Surveying refers to the detailed inspection of an object or area in order to define its boundaries, establish its characteristics, and determine its potential.
Using traditional ground-based survey methods, a 60-acre site could easily take two or even three weeks to survey. But using drone mapping reduces that process to four days or less.
One project has taken about 18 days to perform a manual survey of the 90-acre site, process the data, and finalize the deliverable. With a drone, they were able to cut this process down to just 3 days, making their drone survey workflow 6X more efficient than traditional surveying.
By acquiring faster data from the sky – in the form of geo-referenced, ortho-corrected digital images, with resolutions down to 1.5 cm / 0.6 in per pixel – millions of data points can be gathered in one short flight.
