Foresters and forestry planners utilise GIS in many ways to help plan tree harvests, often years in advance, to ensure they have the right infrastructure in place, when it is required. Planning where to put new roads, locations for logging equipment (e.g. cable haulers) and work sites, terrain modelling, identifying hazards and forestry mapping are all done using GIS.

An emerging development in Forestry is the use of LiDAR (Light detection and ranging). Using LiDAR data in a GIS, foresters are able to create very accurate models of trees and the terrain beneath them. This allows them to calculate and identify ground heights, slopes, tree volumes, vegetation density, wood products and hazards with immense precision. Combined with the ability to model vegetation and canopy cover, LiDAR has become a very powerful dataset. The high resolution and accuracy of LiDAR provides foresters with the best available information, allowing them to make better decisions and ultimately save on costs.

People who work in forestry often have a forestry related qualification, and supplement this with geospatial software and solutions.
