The versatile SLAM based mapper, making data capture fast and simple.
Emesent Hovermap Payload

Hovermap is a smart mobile scanning unit which can be hand held or mounted to a drone to provide autonomous mapping in challenging inaccessible areas. Equally capable above ground or underground, indoors or out, Hovermap is your complete mobile LiDAR mapping solution.

Hovermap’s quick release mechanism makes it easy to switch from drone to handheld use, enabling the collection of critical data both in the air and on the ground, with the ability to automatically merge the results. Weighing only 1.8kg, it is easily portable and compatible with smaller drones such as the DJI M210.

With this powerful combination you’ll be on your way to capturing LiDAR data like never before.


Hovermap Above Ground Rapid Scanning
Collision avoidance

Hovermap acts as a virtual safety bubble around the drone to prevent collisions. LiDAR data is processed on-board in real-time to produce a local 3D map of the surroundings.

Obstacles such as telecom towers, fences, trees, poles, wires and people can all be detected and avoided.

SLAM based 3D mapping

World leading Simultaneous Localisation and Mapping (SLAM) allows mobile mapping even when GPS is unavailable.

Hovermap Above Ground Rapid Scanning
GPS-denied flight

Drones usually rely on GPS for localisation, navigation and flight control. Hovermap uses LiDAR data and advanced algorithms on-board in real-time to provide reliable and accurate localisation and navigation without the need for GPS.

This allows drones to fly autonomously in GPS-denied environments, enabling a host of new applications such as flying and mapping in underground mines, inside warehouses or inspecting underneath bridges.

Unique Design

Hovermap has been designed to allow it users to switch easily from drone to handheld use enabling the collection of critical data in challenging areas.


Hovermap is lightweight, and yet robust enough to withstand the demands of environments such as underground mines. Made from a machined aircraft-grade aluminium frame combined with carbon fibre composite panelling, the Hovermap payload is light yet strong enough to support its rotating LiDAR while remaining stable in flight. Switching between drone to hand held scans can be done with the click of a button using Hovermap’s quick release mechanism.
