1 What are TLS and LiDAR?

TLS stands for terrestrial laser scanning, which is a method of using a laser scanner mounted on a tripod or vehicle to scan a scene or object from a fixed position. LiDAR stands for light detection and ranging, which is a method of using a laser scanner mounted on an aircraft or satellite to scan a large area or terrain from above. Both methods produce point clouds, which are collections of 3D coordinates that represent the shape and surface of the scanned target.

To ensure stakeholders grasp the terrain clearly, I emphasize showcasing 3D data, which includes visualizations, detailed point clouds, and high-resolution imagery. Post this, it is beneficial to provide detailed reports explaining our methodology, data quality, and analysis. For presentations, I like to explore online platforms and software like Potree, which enables stakeholders to explore data from anywhere. Another way to involve your stakeholders for better comprehension according to me is utilizing video conferences for live demonstration and discussions to ensure real-time interaction and clarification.

TLS is technically is a subset of LiDAR group, which consist of any technology using light to detect and measure. Even though these terms are often use in your suggested way, many professionals would probably disagree.

2 How to visualize TLS and LiDAR data?

One of the main challenges of working with TLS and LiDAR data is how to visualize them in a way that is clear, accurate, and engaging. Depending on the purpose and audience of your presentation, you may need to use different tools and techniques to display your data. For example, 2D maps and images can be created with software such as ArcGIS, QGIS, or Photoshop to apply color, shading, texture, or symbols. You can also overlay other data sources, such as aerial photos or satellite images. 3D models and animations can be created with software such as SketchUp, Blender, or Maya to show the details, dimensions, and dynamics of your data. Additionally, charts and graphs can be created with software such as Excel, Tableau, or Power BI to show the distribution, trends, or relationships in your data. Interactive dashboards or widgets can also allow your audience to explore your data and filter by variables or criteria.

3 How to report TLS and LiDAR data and results?

Communicating and presenting TLS and LiDAR data and results requires concise, informative, and persuasive reporting. Depending on the scope and format of the report, it may include an executive summary, introduction, methods, results, discussion, and conclusion. The executive summary should be a brief overview of the main purpose, methods, findings, and recommendations of the report. The introduction should provide background information on the context, objectives, and scope of the project. The methods section should explain the data collection and analysis methods used in the project. The results section should use visualizations to illustrate the data and results obtained from the project. The discussion should compare and contrast the data with existing literature or theories. Finally, the conclusion should summarize the main points and outcomes of the report.

There are a few platforms that allow you to upload point clouds and overview maps to a browser, allowing you to share directly with clients and stakeholders. In order to communicate the data effectively, tell your stakeholder how they can use it and why it's "better than the old way."

4 How to tell a story with TLS and LiDAR data and results?

When communicating and presenting TLS and LiDAR data and results, it is important to tell a story. A story connects data and results with a larger theme, message, or purpose. It can help engage your audience emotionally, intellectually, or creatively, as well as persuade them to take action or change their behavior. To tell a story effectively, you must define your audience, goal, structure, and style. Know who your audience is, what they care about, and what you want to achieve with your presentation. Then determine how you want to organize your presentation and what tone and language you want to use. Finally, use humor, emotion, analogy, metaphor, or imagery to make your story memorable and relatable.
