Using lidar for vegetation cover estimates: A guide

Lidar is a surveying technology that has been used for many years to map the earth’s surface. Recently, lidar has also been used to estimate vegetation cover. This guide will explain how lidar is used to estimate vegetation cover, and will provide some tips on how you can use lidar data for your own vegetation cover estimates.

Lidar works by sending out a laser beam and measuring the time it takes for the beam to bounce back. The lidar system then uses this information to create a three-dimensional map of the earth’s surface.

Vegetation cover can be estimated using lidar data in two ways:

  • By looking at the density of vegetation canopy
  • By looking at the height of vegetation canopy

The density of vegetation canopy can be estimated by looking at how much of the lidar signal is scattered by vegetation. The more dense the vegetation, the more scattering there will be. The height of vegetation can also be estimated by lidar, by looking at how far away from the ground the lidar signal returns. taller plants will cause the lidar signal to return from a greater height.

Both of these methods have their advantages and disadvantages. The advantage of using lidar to estimate vegetation cover is that it can be done from a distance, without having to physically enter the area. The disadvantage is that lidar data can be expensive, and it can be difficult to interpret.

If you are interested in using lidar data for your own vegetation cover estimates, there are a few things you should keep in mind:

  • Make sure you have high-quality lidar data. Low-quality data will not give accurate results.
  • Be prepared to spend some time interpreting the lidar data. This is not a quick or easy process.
  • Work with an experienced lidar analyst to ensure that you are using the data correctly.

If you follow these tips, you can use lidar data to accurately estimate vegetation cover. This guide has only scratched the surface of what lidar can do – there are many other uses for this versatile technology. So if you’re looking for a new way to collect data, be sure to give lidar a try.
