Light Detection and Ranging (LiDAR) sensors use light energy, emitted from a laser, to scan the ground and measure variable distances. The end result is a rich set of elevation data that can be used to produce high-resolution maps and 3D models of natural and man-made objects.
Compared to other survey methods, LiDAR collection yields the highest fidelity data.
Visual sensors are instrumental in surveying and land use applications, plant counting and volume measurement, surveillance, photogrammetry, 3D reconstruction and emergency response.
We consider many variables to consider when choosing the appropriate visual sensor including how the outputs will be used, the level of accuracy needed and anticipated flight conditions.
Video sensors capture high definition footage during aerial surveys and inspections, streamlining documentation. They’re ideal for aerial mapping and imaging, photogrammetry and 3D reconstruction, plant counting, volume measurement, surveillance, emergency response, surveying and land use applications.
Our sytems allow HD video footage to be live-streamed to multiple devices on the ground. As a result, we’re able to make informed decisions, in real-time.
The ability to geotag video footage (live during the flight or afterward) ensures data from multiple surveys can be accurately aligned and compared.
Thermal sensors measure the relative surface temperature of land and objects beyond the scope of human vision.
A microbolometer is a specific type of resistor used as a detector in a thermal camera. When long wave infrared radiation emitted from objects strikes the microbolometer, it heats up and this changes its electrical resistance. These changes are converted to electrical signals and processed into an image.
Our thermal sensors have many applications including surveillance and security, water temperature detection and water source identification, animal detection and heat signature detection.
A standard visual sensor collects red, green and blue wavelengths of light. Multispectral sensors are able to collect these visible wavelengths as well as infrared radiation and ultraviolet light (non-visible wavelengths).
Multispectral sensors are instrumental in plant health and management. They can pinpoint nutrient deficiencies, identify pest damage, optimize fertilization and assess water quality. Detailed insight can also be secured using algorithms from Vegetation Indices.
Our multiband sensors are manufactured specifically for multispectral data collection. Each band is collected separately so there is no need for multiple flights. Multiband sensors also enable us to mix different band combinations to meet our client’s needs.
Hyperspectral sensors collect hundreds of narrow bands of data along the electromagnetic spectrum. The sensors produce narrow bandwidths (5-10 nm) and secure roughly 100 to 200 spectral bands of data per image pixel. The data is collected as a three-dimensional hyper-cube with x, y and λ values.
Each pixel gets its own spectral profile containing location data, followed by hundreds of digital numbers that align with the corresponding spectral bands.
These sensors can detect and identify minerals, vegetation and other materials that are not identifiable by other sensors. They are used in plant nutrient status, plant disease identification, water quality assessment, foliar chemistry, mineral and surface chemical composition.
Hyperspectral sensors have two methods for scanning: Push Broom and Whisk Broom.
Our Push Broom sensors, have been selected as they are ideal for drone use, capturing the full spectral data simultaneously as the drone moves forward using a line of sensors that runs perpendicular to the drone’s flight direction. With this method, the scanner is able to look at a particular area for a longer period of time enabling more light to be gathered.
