LiDAR Surveying and Photogrammetry
ACI has advanced measuring equipment for LiDAR Surveying and Photogrammetry that includes airborne LiDAR, airborne LiDAR unmanned (drones), terrestrial LiDAR (mobile and static), aerial photogrammetry, and echo sounder technology.
Selecting which 3-D scanning technology to use for a particular project can be challenging. ACI compares technologies to select the option that will quickly capture the necessary surveying data at the lowest cost to the client.
Terrestrial LiDAR provides a higher point density and accuracy in comparison with any other 3-D scan technology. However, time requirements and limited access to project sites can complicate the collection of terrestrial LiDAR information. By using airborne LiDAR, surveying data on all types of terrain, whether flat, wavy, or mountainous with or without vegetation, can be acquired.
Mapping generated through aerial photogrammetry also provides a cost-effective method of establishing an accurate digital base for tasks such as urban planning, terrain analysis, and forest management.
ACI uses bathymetric information from echo sounder technology to obtain surveying data near coastlines, in harbors, and near shores and banks, as well as to locate objects on the ocean floor.
The word LiDAR is an acronym for Light Detection and Ranging. It is a powerful system that integrates laser technology with GPS and inertial measurement unit to generate a point cloud, which can be used to extract surveying data for different uses and to create 3-D digital models of all kinds of terrains and urban areas.

Why use LiDAR?
LiDAR offers the following advantages compared with conventional topographic methods:
- Highly precise topographical surveys in a faster manner
- Day and night operation
- Fast processing
- Fully Digital Data Collection
- Very discreet measurement method capable of accessing remote areas
- Environmentally friendly since it does not require invasive openings in dense vegetation zones
