Aerial Lidar is a great way to compile past and current data to view changes in the earth’s surface. There are many reasons why individuals decide to choose aerial Lidar over other types of GIS surveying techniques. In fact, many people have started using aerial Lidar and topographic maps together to complement one another. These individuals have discovered that more information can be gained if the two resources are being used together, rather than alone. But if you were to pick one way of navigating the earth’s surfaces to view changes, it’s important to understand that there are reasons in doing so.

Advantages of choosing aerial Lidar photos over traditional topographic maps.

  1. Lidar photographs provide users a current pictorial view of the earth that no other map can equal.

  2. It’s easy to get your hands onto. Typically, after a Lidar photograph is taken, the user will have access to the photos within the next few hours. When a topographic map is made, it can take weeks, if not months to prepare.

  3. Users can have pictures of areas taken that are inaccessible by foot.

  4. A Lidar photo can show day-to-day comparisons of certain areas.

  5. A Lidar photo can show objective and permanent record of day-to-day changes in certain areas.

Unfortunately, with every advantage there is a disadvantage.

  1. Position of the Lidar photo are approximate to location and scale.

  2. There are times when detailed variations of terrain and other features are not readily apparent without a stereoscopic viewing instrument on hand to avoid overlapping photography.

  3. Aerial Lidar photographs may be difficult to use during poor lighting conditions.

  4. Lidar photographs may lack in marginal data.

  5. Interpretation of each Lidar map takes more training.
