If you're looking to collect LiDAR data, ArcGIS offers several free options. But if you want to do it yourself, you'll need the right equipment and technology.
LiDAR
systems are designed to capture LiDAR data, and depending on the data you need, you can use a portable LiDAR scanner for walking, an airborne LiDAR, or a scanner mounted on a vehicle. A LiDAR instrument is composed of a laser, a scanner, and a specialized GPS receiver.Airplanes and helicopters are the most common platforms for acquiring LiDAR data in large areas. There are two types of LiDAR: topographic and bathymetric. Topographic LiDAR typically uses near-infrared laser to map the land, while bathymetric LiDAR uses green light that penetrates the water to measure the elevations of seabeds and riverbeds. By sending out repeated pings, a LiDAR device can also detect how nearby objects move, their speed, and whether they are facing the LiDAR device or not.
3D at Depth, a global provider of advanced subsea LiDAR solutions, has continued to validate the LiDAR market for the upstream oil and gas industry. In this article, we will explore three innovative ways to collect LiDAR data: portable LiDAR scanners for walking, airborne LiDAR systems, and vehicle-mounted scanners. Portable LiDAR Scanners for Walking Portable LiDAR scanners are designed for walking applications. They are lightweight and easy to use, making them ideal for collecting data in urban areas or other areas with limited access.
Portable LiDAR scanners can be used to map buildings, streets, sidewalks, parks, and other features in detail. They can also be used to measure distances between objects or points of interest. Airborne LiDAR Systems Airborne LiDAR systems are used to collect data from large areas quickly and accurately. These systems are mounted on airplanes or helicopters and use lasers to measure distances between objects on the ground.
Airborne LiDAR systems can be used to map terrain features such as mountains, rivers, lakes, forests, and other natural features in detail. They can also be used to measure distances between buildings or other man-made structures. Vehicle-Mounted Scanners Vehicle-mounted scanners are designed for collecting data from roads or other areas with limited access. These scanners are mounted on vehicles such as cars or trucks and use lasers to measure distances between objects on the ground.
Vehicle-mounted scanners can be used to map roads in detail or measure distances between buildings or other man-made structures. In conclusion, there are several ways to collect LiDAR data depending on your needs. Portable LiDAR scanners are ideal for collecting data in urban areas or other areas with limited access. Airborne LiDAR systems are used to collect data from large areas quickly and accurately.
And vehicle-mounted scanners are designed for collecting data from roads or other areas with limited access.
