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 can carry out additional flights at lower altitudes or from different approaches.
The 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.
Using remote aerial systems has many benefits compared to traditional ground-based survey methods and practices.

Aerial systems are a cost-effective and accurate way of documenting and surveying historical and archaeological sites. Orthographic maps generated from the aerial data can be used for many different types of analysis, or further developed into 3D visualisations showing what sites looked like at different periods in time.
UAVs (drones) are arguably the fastest and most versatile method for capturing data for 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. Satalite imagery from Google is often lacking in detail especially at higher zoom levels. Orthographic aerial maps are a great way to show visitors the layout of your site and when combined with markers pinned to the terrain it serves as an interesting way to show key information about your services. With the addition of photos and videos integrated into the map, customers get a useful and memorable experience prior to and during their visit.
