ISR is the coordinated and integrated acquisition, processing and provision of timely and accurate information and intelligence to support command and control’s management of live events in real time. ISR encompasses multiple activities related to the planning and operation of systems that collect, process, and disseminate data in support of current
and future operations. ISR gimbals provide you with 360˚ coverage of any domain you are operating for PNG and usually Infrared and or thermal imagery.

Multispectral imagery employs broad wavelength bands over the visible, near infrared and short-wave infrared spectrum. Utilising the differing spectral reflectance of different substances, multispectral imaging can clearly detect vegetation, soil moisture and even fires within a single image.
Indices are used to categorise the data collected and will return differing data depending on the application. A common index is the NDVI which can measure the photosynthetic activity of a scene, with healthy plants appearing green, stressed plants, which may indicate a lack of water will appear redder and non-photosynthetic material appearing red. This can allow farmers to focus their efforts on the correct section of their land.
This is just one example of the multitude of applications of multispectral imagery.
Hyperspectral poses an advantage over multispectral when specific molecular absorption data is required due to the detailed spectral resolution. It can provide an inference to the biological and chemical processes occurring within a scene as well as identifying surface compounds.

Photogrammetry utilises the full visible spectrum to produce real colour, 2D or 3D maps and models. Using many overlapping photographs of an area of interest the images are stitched together in post processing software to develop the final product. Since photogrammetry uses natural light to collect all RGB images, products are an accurate depiction of the real world and can provide unparalleled details with centimetre spatial resolution.
Photogrammetry is used for developing detailed orthomosaic maps of areas that can aid in management and monitoring. Famously Google Earth and Google Maps use photogrammetry to produce the 2D and 3D images of Earth.

A LiDAR system measures the precise distance to an object which can be utilised to gather 3D information about the Earth’s surface with centimetre resolution. To achieve such precision, a LiDAR system employs laser pulses and measures the time for the pulse to return, coupled with extremely accurate GNSS receivers.
Due to the LiDAR system actively illuminating the target with laser pulses, distance measurements are possible even through canopies and foliage.
The detailed focus of a LiDAR system allows it to be applied to the desired industry across the specific terrain or elevation map.
