Aerial surveying

Aerial Surveying

Using Enterprise-grade RTK surveying drone, XAG is able to provide CM-level precision aerial mapping with in-house high-resolution RGB and multi-spectral cameras. Our services include aerial orthographic mapping, digital surface model mapping, precision control mapping, multispectral mapping and aerial photography.

These services are invaluable when identifying issues you might not even be aware of as our high resolution maps provide advanced details of your property, saving you time and money and monitoring events such as crop stress. In addition, having a birds-eye view of your land will afford you greater insight into how to better utilise your acreage, make highly informed decisions and affect how you plan and manage your crops.

Precision Contour Mapping

Water management on farms requires accurate measurements of contours for diverting water flows, building dams and leaky weirs and for irrigation purposes. Autonomous drones can fly large areas with accuracies of 1-2cm in both the vertical and horizontal dimensions if required. The contour maps can be displayed by individual contours at any spacing or as a banded colour visual between contours.

Aerial Orthographic Mapping

An orthophoto, orthophotograph or orthoimage is an aerial photograph geometrically corrected (“orthorectified”) such that the scale is uniform: the photo has the same lack of distortion as a map. Unlike an uncorrected aerial photograph, an orthophotograph can be used to measure true distances, because it is an accurate representation of the Earth’s surface, having been adjusted for topographic relief, lens distortion, and camera tilt.

Digital Surface Model Mapping

This picture of a research field of wheat is a digital surface model and represents the earth’s surface and includes all objects on it. This can then be used for analysis of say the height of the vegetation and measure the variation in height across a grass paddock, the roughness of a wheat crop surface or difference in growth rates between varieties. This is of a paddock in Boorowa NSW.

Multispectral Mapping for Crops

Light of different wavelengths reflected from crops can be measured and it represents the nature of the the surface, i.e. plants can be distinguished from ground. Depending on the plant and it’s state, different leaves can reflect differently at different wavelengths.

Hyperspectral detection can measure hundreds of specific wavelengths between 350-750 nm and multispectral cameras 4 or 5 bands. Red here is ground, with different shades of green for the vegetation. Wheat crop, Boorowa, NSW

Aerial Photography of Property

Normal RGB cameras can be used to get aerial views of property, plants and animals which can be used as a normal record of a place or an event or the consequence of say a weather event. They can also be used to count vegetation or to get 3D reconstructions of the property. Orchard, Kulnura, NSW

Drone Inspections of Property

Drones can be used to inspect and analyse a wide range of issues. These could include on farm water structures or off farm, wind turbine generator blades, solar panel, water infrastructure, power-line and towers.

XMission is an industrial level surveying drone which can be equipped with two cameras, the XCAM RGB which captures high resolution images of landscapes (1 cm/pixel) and the multi-spectral camera which can capture numerous spectral bands including green, red, red edge, and near infrared.

This versatile, state-of-the-art model is invaluable to capturing outstanding images which can be processed through XAG Cloud or third-party data processing tools to generate NDVI and other index maps and ensuring data is acquired with extreme accuracy.
