Abstract
“A pixel is worth 1024 bits”! Captured from the right perspective, every forest manager now sees aerial images as essential in their toolkit! Converting the data bits from a drone or a Remotely Piloted Aircraft System (RPAS) to actionable information bytes for supporting forest operations had been the journey FPInnovations took over the last 6 years. The objective was to assess whether RPASs represented a suitable platform for forestry operations and whether their use provided added value to various applications. Diff erent types of RPASs and miniaturised sensors have been tested in the forestry environment.

Abstract
In recent years, when high-resolution and low-altitude imaging of forests is needed for surveillance, inventorying or continuous monitoring, the tool of choice is an unmanned aerial system (UAS), commonly known as a drone. Especially useful are vertical take-off and landing (VTOL) systems, which can take off and land vertically, and which can provide detailed information in confined or hard-to-reach areas. However, when it comes to forest operational needs, one question is frequently asked: Do the added advantages of high-end systems justify their cost ($60,000), or do low-end systems ($6,000 plus a tablet) provide similar or acceptable output?
Abstract
Ces dernières années, lorsqu'une imagerie haute résolution et à basse altitude des forêts est nécessaire pour la surveillance, l'inventaire ou le suivi continu, l'outil de choix est un système aérien sans pilote (UAS), communément appelé drone. Les systèmes à décollage et atterrissage verticaux (VTOL), qui peuvent décoller et atterrir verticalement et fournir des informations détaillées dans des zones confinées ou difficiles d'accès, sont particulièrement utiles. Toutefois, lorsqu'il s'agit des besoins opérationnels des forêts, une question revient fréquemment : Les avantages supplémentaires des systèmes haut de gamme justifient-ils leur coût (60 000 $), ou les systèmes bas de gamme (6 000 $ plus une tablette) fournissent-ils un rendement similaire ou acceptable ?

Abstract
A new era of remote sensing has emerged with the arrival of unmanned aerial vehicles (UAVs) for civil applications, especially in small area imaging, monitoring and analysis. Advances in miniaturisation of instrumentation enabled development of several robust, light-weight and autonomous sensors that can be easily installed into these microcrafts. Initiating with a simple visible-RGB camera, these mini-imagers have progressed to include sensing in multiple spectral regions of the electromagnetic spectrum, both in the reflected and emitted regions, which are useful for remote sensing. With an interest in expanding the scope of applications of UAV in forestry beyond the use of orthomosaics/simple mapping and 3D modeling with an RGB camera, FPInnovations wished to have a first impression of the new radiometric cameras that are commercially available in the market. Radiometric cameras accurately measure irradiance, illuminance or reflectance from an object that can help in detecting features on the image characteristics (e.g. vegetation) like vigor, stress, moisture, temperature.

Abstract
Most often UAV data is acquired to have a single overview of the area of interest through stitching of several images that are corrected for the terrain/topographic effects called ortho-mosaicking. This requires post-processing of the data using specialized software. Terrain is estimated from 3D point clouds generated through photogrammetric procedures (image matching) on the overlapping images. There are multiple challenges associated with processing of imagery acquired using a UAV for generating an orthomosaic.
