We will work with you to collect the terrain information from the ground and from the sky with drone mapping to create accurate digital terrain models (DTM), digital elevation models (DEM) and photogrammetric maps of your property using unmanned aerial vehicles (UAV) to capture the surface data from above.
The unmanned aerial vehicle (drone) will fly a pre-programmed flight path of your property to capture data with the onboard sensors. This data can be combined with a ground survey using equipment such as an RTK enabled GNSS system to generate ground control points which which will be included in the post-production workflow to ensure that the positioning is accurate.
Through post-processing of the data with the ground control points we can achieve sub-centimeter RMSE in our imagery and consistent sample distance of 2 CM or less. Once processed we can output the surface data in a variety of formats depending on your target application and which software you are using i.e. AutoCAD, ARCGIS, QGIS, Google Earth etc.
Output formats include: GeoTIFF (TIFF), RAW Images (JPG), Google Earth (KML), Colorized DTM (TIFF)
Normalized Difference Vegetation Index (NDVI) Imaging
NDVI compares Near Infrared and Red light. It is great for measuring healthy, green vegetation over a wide range of conditions. We have equipped our drones with a multispectral IR sensor to efficiently capture this data in combination with normal RGB bands.
NDVI is a an index that describes the difference between visible and near-infrared reflectance of vegetation cover and can be used to estimate the density of green on an area of land.
UAV Ontario provides aerial survey for farms, provincial/municipal conservation areas and land trusts to gather information pertaining to plant population, disease, flowering, pest detection, plant height and condition.
