After deciding on the area or structures needing to be mapped, we use automated flight systems to plan a grid route that covers the area.
We set the drone flying at a constant speed with the camera pointing vertically downwards capturing images every couple of seconds. If extra detail is required we carry out additional flights at lower altitudes or different approaches.
This data is then processed using different software systems that measure the similarities and differences between each image and stitches them together into a high-resolution, satellite-style image.
We can then accurately overlay this image using geo-referenced data, or manually position over existing maps.
Aerial systems are a cost effective and accurate way of documenting and surveying historical and archaeological sites. 3D models generated from the aerial data can be used for many different types of analysis, or further developed into 3D tours showing what sites looked like at different periods in time (like our Wheal Prosper example above).
3D aerial mapping provides much faster and detailed methods of carrying out geological / landscape surveys. It's also a safer alternative for locations that are difficult or dangerous to reach, such a cliff erosion inspections. An automated remote system also means that the data can be analysed again in the future from the same survey points.
For outdoor leisure businesses, such as golf courses showing customers what you have to offer is vital. Interactive 3D tours of individual elements of your site, or a map of the whole location is a great way to encourage visitors and show key information about your services. Combined with photos and videos, customers get a useful and memorable experience prior to and during their visit.
