Drone Based Mapping, using a range of photographic sensors and photogrammetry software, an area can be mapped in high quality.
The postprocessing results in an orthophoto mosaic, with the edition of a 3D model and Digital Elevation Models (DEM’s) as standard output.
Measurements include basic measurements of any object visible in the imagery besides more complex measurements, e.g. 3D based volumetric measurements in comparison to the ground level; this can include excavations and stockpile measurements.
Near-Infrared or Red Edge spectral images can be used to extract among other, vegetation. With a combination of the Red spectrum, NDVI’s can be calculated. The NDVI provides plant health status and can be of great value for the agriculture and conservation community, where the health status of vegetated areas are of importance.
Client-specific, customised automated object extraction for a range of visible object within the surveyed data are available. Examples include wildlife counting and morphometric data extraction, Vegetation species-specific data extraction, geographical feature extraction and habitat mapping.
Digitising drone base imagery data to be used in a GIS. The data include raster and vector data types. In a range of file formats like KML, .shp, .tiff & PDF. With customised projection as per the customers needs to ensure easy integration with existing geo-databases
A GIS analysis of post-processed drone-based data can include the following: Cut and fill analysis, watershed, contour, point pattern analysis and hotspot analysis.
