Unmanned Aerial Vehicles (UAVs) popularly known as Drones have become proven technology in the sphere of Aerial Mapping and Survey. The use of Drones/UAVs and aerial mapping services are increasingly becoming the go-to solution for many Geospatial professionals and industries. At Orbital Africa, we're at forefront in employing latest drone/UAV technology incorporating SenseFly hardware (drones) and Pix4D software products. Below is a simple workflow of Drone Images/Big Data processing. At Orbital Africa, we also offer Training on Drone/UAV/UAS Mapping encompassing flight planning, flying the drone, data download and processing using software such as Pix4D, Agisoft, Drone Deploy etc.

Orbital Africa is the leading drone/UAV mapping company based in Kenya with branches in Ethiopia, Tanzania, Uganda, south Sudan, Rwanda, Botswana and Africa at large.. We employ a number of drones e.g. DJI Phantom 3, eBee SenseFly from various manufacturers across the globe. Several software available in the market for processing drone images and creating orthomosaics and Digital Surface Models (DSMs), Digital Elevation Models (DEMs) etc. include Pix4D, Agisoft among others. Drones for mapping normally fly at an altitude of 100 metres to 300 metres.
Notably, the spatial resolution of the drone images decreases considerably with increase in altitude but the drone is capable of capturing large image scenes. With the drones, one can obtain an image of up to 2cm Spatial Resolution! We also hire, rent or lease all types of drones at affordable rates.
At Orbital we use various drones such as DJI Phantom 4 RTK, eBee X and SQ. The eBee SQ is an advanced Agricultural Drone that takes professionals such as crop consultants, growers and researchers from drone to action, simply and efficiently. The eBee SQ can fly for up to 55 minutes on a single battery charge. This performance enables it to cover up to 500 acres in a single flight at 120 Metres above ground level—up to 10 times more ground than small quadcopter drones—for extremely efficient crop monitoring and analysis. The result is fewer flights per project, for less time spent collecting data and more time acting on it.
Arguably, with a large increase in the amount of physical data being collected, this does mean an increase in office time spent processing and utilizing this data. However, this expansion is canceled out many times over by the huge time savings a drone produces out in the field. Many of senseFly’s surveying customers say, for example, that large jobs that once took weeks can now be completed in just a few days, and that a week’s worth of traditional data collection is now achieved in just one day. Last but not least, less time spent on the ground means staff safety is improved by minimizing risk to surveying teams when measuring sites such as mines, unstable slopes and transport routes. Simply choose take-off and landing locations that are out of harm’s way.
Orbital Africa has successfully carried out many Drone/UAV Mapping projects in Kenya and Africa region at large. Recently, we conducted drone mapping project in a 17-acre parcel of land in Kiambu County. The outputs of the project was a 3cm resolution Orthomosaic, a DEM, DSM and Contours. The sample Orthomosaic can be viewed here: >>Kiambu Drone Project.
