The attention and interest in LIDAR data has grown considerably during the 2000s. As a well-established distance analysis method, it presents results to study and the critical question is "How good is the result to study?". I several previous publications there often is an uncritical and positive attitude to the technology. Beneficial results are emphasized instead of critical reviews of the whole technology. Early in the process, there are several different aspects, which can be disruptive moments. How the scan of LIDAR is organized, as well as the post-treatment process. The chosen ancient type of fossil arable land can be problematic. The complex systems of the fossil farmland can be hidden with incorrect visualization. Combining altitude models based on Hillshade and Slope prevents the fossil farmland system from being concealed. Another aspect to consider is vegetation. In our question we want to investigate how common types of vegetation affect visibility. We chose to use the Swedish Environmental Protection Agency's ground cover data and have looked at three different vegetation types. Spruce forest (outside wetland), Nobel deciduous forest (outside wetland) and Temporary non forest (outside wetland). Of the three vegetation types, Temporary non forest (outside wetland) presents difficulties in visualization, the quality of the ground surface in the height model varies considerably. Spruce forest (outside wetlands) has opportunities, however the results can be varied. Noble deciduous forest (outside wetland) has the simplest material for interpreting, with remains that have not previously been registered with FMIS.
