Drone images specifications

The Globhe standards for drone images

The Globhe standards will be applied if others are not specified in your order.

Drone images, also known as aerial images, refer to photographs or data captured by drones from an elevated perspective. Drones are equipped with cameras or sensors that enable them to capture high-resolution images and collect geospatial data over vast areas with remarkable precision and flexibility.

These images offer a unique perspective, allowing for comprehensive visual documentation and analysis of various landscapes, structures, and environments. Utilizing drones allows you to access crucial data for applications such as mapping, surveying, inspection, environmental/climate monitoring, and more. By leveraging the power of accurate and accountable drone images, you can gain valuable insights, make informed decisions, and unlock new possibilities across a wide range of industries and sectors.

Deliverable specifications

Flight height

Definition: the altitude or elevation at which a drone operates during an aerial mission or flight.

Globhe standard: 110 meters AGL*, in line with national and local regulations in place.
*Above Ground Level = the altitude or vertical distance between the drone's current position and the Earth's surface.


Definition: the rate at which the drone can travel through the air or move from one location to another. It is a measure of how quickly the drone can cover a certain distance within a given period of time. The speed of a drone is typically expressed in terms of a linear velocity, often measured in meters per second (m/s). The speed of a drone can vary depending on various factors, including its design, size, weight, propulsion system, flight mode, and external factors (such as wind speed and direction).

Globhe standard: 3 - 5 m/s and adjusted to meet the technical requirements.

Spatial resolution / Ground Sampling Distance (GSD)

Definition: the level of detail and clarity with which the physical features on the Earth's surface are captured and represented in drone images. The spatial resolution defines the size of the smallest object that can be distinguished in drone images and it is typically measured in terms of the ground sampling distance (GSD), which represents the physical distance on the ground covered by each pixel. The GSD achieved is a function of the drone sensor/camera specifications and the flight height.

Globhe standard: 2 - 3 cm/px.

Data format

Globhe standard: RGB images: geotagged JPEG (.jpg) - digital images captured by the drone's camera which, between the others, contain information about the embedded geographical metadata known as geotags.

Definition: geotagging consists in adding geographic information to the image file, such as the latitude and longitude coordinates of where the image was taken. Overall a geotagged drone JPEG combines the visual information captured by a drone's camera with embedded geographical metadata, providing valuable location-based context to the captured image.

Drone models and sensors

Globhe relies on a wide range of commercial drone models available through our Crowddroners, including but not limited to multirotors (i.e. quadcopters, hexacopter, octocopters) and fixed-wing, mounted with every sort of commercially available sensor as payload*.

*Payload = the additional equipment or devices that are carried or attached to a drone in order to perform specific functions or tasks. These payloads can vary depending on the purpose and capabilities of the drone. The most common drone payloads are RGB cameras for aerial photography or videography, sensors for data collection (such as thermal, multispectral imaging, or LiDAR sensors), and specialized equipment for tasks like seedlings, crop spraying, or search and rescue operations.

If the drone model and/or sensor are not selected, the GLOBHE team will choose the suitable drone needed to meet technical requirements, also based on availability.
