TREE LOCATION

LiDAR technology has revolutionized forestry management, particularly in the GeoTagging of trees. It can be done more efficiently and accurately since it will be done at the comfort of an office instead of the conventional manual fieldwork of Forest Surveys which is labor-intensive and highly dangerous. LiDAR enables rapid data acquisition that minimizes cost, time, and more importantly protects lives.

TREE IDENTIFICATION

There are two definitions of Tree Identification: one refers to a tree's identity or Tree ID (i.e., what kind of tree is it), while the other refers to the process itself of identifying what kind of trees there are in an area through examining their tree type, leaves, flowers, fruits, barks, twigs, and forms. Since our LiDAR is mounted on a Cessna 172k aircraft, Forest Survey through LiDAR mapping helps identify trees faster and store the data gathered in a comprehensive and accurate inventory. From the data produced by LiDAR scanning, you may get the tree’s height, diameter at breast height or DBH, as well as the tree’s species. The inspection of woodlands and forests to ascertain different trees in a location can now be conducted with less time-consuming and less hazardous conventional fieldwork.

DIGITAL SURFACE MODEL (DSM)

A Digital Surface Model or DSM is a canopy model that contains only the top buildings, trees, and vegetation. Points on the ground are shown when there is nothing on top or over it. Basically, a DSM is a three dimensional representation of the Earth’s surface that includes the natural terrain and the heights of vegetation, buildings, and other above-ground structures. Canopy models show the amount of forest cover and tree’s height. Forest Survey with DSM helps in identifying areas for reforestation. However, DSM should not be confused with Digital Elevation Model or DEM, which is a representation of the bare terrain with elevations.
