Introduction to Forest LiDAR: Transforming Forest Management Modern forest management faces multiple challenges, from monitoring large areas of land to the need for accurate inventories of biomass and tree cover. LiDAR (Light Detection and Ranging) technology has emerged as an essential tool to address these challenges, allowing highly accurate three-dimensional data of the natural environment to be obtained without the need for physical contact with the ground. In the forestry context, LiDAR allows modeling of entire forests with unparalleled resolution and detail. Thanks to its ability to penetrate the vegetation canopy, this technology reveals the upper canopy structure as well as the lower layers and soil, providing a comprehensive representation of the forest ecosystem. Fundamental Principles of LiDAR Technology LiDAR works by emitting pulses of laser light from a mobile, aerial or terrestrial platform. These pulses bounce off objects in the environment and return to the sensor, which measures the return time to calculate the distance. Applied to forest environments, this system generates millions of georeferenced points that make up a three-dimensional point cloud. Each of these points contains altitude and reflection information, making it possible to distinguish between the tree canopy, intermediate branches and the ground. This unique penetration capability makes LiDAR an ideal technology for dense forested environments where other remote sensing methods are limited. LiDAR Applications in Modern Forestry Forestry LiDAR applications are broad and cover multiple areas of environmental management, land planning and conservation: Automated Forest Inventory: Allows estimating parameters such as tree height, diameter at breast height (DBH), aerial biomass and forest density accurately and quickly. Vertical Forest Structure Mapping: Thanks to LiDAR’s ability to capture multiple returns per pulse, different vegetation strata can be identified, which is useful for characterizing habitats and biodiversity. Digital Terrain Models (DTM): Through the filtering of the point cloud, vegetation elements are eliminated and a terrain relief model is obtained, which is essential for hydrological studies and infrastructure planning. Forest Change Monitoring: By comparing LiDAR flights in different years, it is possible to accurately quantify changes in tree cover, logging, regeneration, fire and pest damage. Logging and Conservation Planning: With three-dimensional data, areas of high ecological value, more accessible areas for logging and critical areas for conservation can be identified. Key Benefits of LiDAR Use in Forest Environments Implementing LiDAR technology in forestry projects brings benefits that far outweigh traditional methods: High Resolution and Accuracy: The models generated allow working with millimeter details, which is key for fine inventories and structural analysis of vegetation. Operational Efficiency: Large tracts of land can be scanned in a single flight, which saves time and reduces operating costs compared to manual field surveys. Under Canopy Detection: Unlike satellite imagery, LiDAR can capture ground data even under dense vegetation cover, improving accuracy in topographic models and ecological surveys. Interoperability: LiDAR data can be easily integrated into GIS systems and with other sources of information (photogrammetry, multispectral imagery) for integrated analysis. LiDAR Implementation in Spain: Projects and Advances Spain has made a firm commitment to LiDAR technology in its territorial and environmental planning strategies. One of the best examples is the National Aerial Orthophotography Plan (PNOA), which includes the generation of LiDAR data on a national scale. Thanks to this program, forestry professionals have access to high-resolution digital elevation models for the entire territory. Many autonomous communities are using LiDAR to develop precision forest mapping, assess forest fire risk and calculate the carbon storage potential of tree ecosystems.

LiDAR: the Laser Technology that is Transforming the World’s Mapping
What is LiDAR and how does this laser technology work? LiDAR (Light Detection and Ranging) is a remote sensing technology based on the use of laser light pulses to measure distances with millimeter precision. It works by emitting thousands of pulses per second from a sensor, which upon impacting objects or surfaces, return to the device. By calculating the round-trip time of each pulse, the system determines the exact distance and generates a three-dimensional representation of the environment known as a point cloud. Thanks to this capability, LiDAR makes it possible to obtain accurate models of terrain, structures or vegetation, even in conditions of difficult access or low visibility. This technology is essential in sectors such as topography, cartography, archaeology, engineering, forestry management and autonomous navigation. LiDAR point cloud: the heart of geospatial data One of the main outputs of the LiDAR system is the point cloud, a massive collection of points with spatial coordinates (X, Y, Z) that represent in great detail the surface of a scanned area. These points allow the generation of digital elevation models (DEMs), digital terrain models (DTMs), 3D topographic maps and advanced geospatial products. LiDAR point clouds are essential for projects that require accurate terrain information, such as urban planning, environmental monitoring, infrastructure works and risk analysis.

Cartography and Projections: History, Types and Current Applications
The Importance of Cartographic Projections in the Representation of the World Cartography is key to understanding the world, but the representation of the Earth on a plane requires the use of cartographic projections. These techniques make it possible to transform a sphere into a map, but involve certain distortions. Today, projections are essential in navigation, urban planning, education and geographic information systems (GIS). If you want to know more about this discipline, we invite you to read our article on what is mapping?. What is a Cartographic Projection? Definition of Cartographic Projection and its Primary Function A cartographic projection is a method of transforming the curved surface of the Earth into a flat map. Each projection seeks to maintain some property (shape, area or distance) by sacrificing others. For example, some projections preserve navigational routes, while others highlight actual proportions between continents. History of Cartographic Projections: From the First Maps to the Digital Era The Origins of Cartography and the First Projections Civilizations such as the Babylonians and Egyptians already used primitive representations of their environment. Over time, cartography evolved thanks to geographers such as Ptolemy, whose maps included the first forms of conic projections. Mercator’s Legacy and Navigation Routes In 1569, Gerardus Mercator designed a cylindrical projection ideal for maritime navigation, since straight lines corresponded to routes of constant bearing. However, it distorted the size of land masses near the poles. Types of Cartographic Projections: Characteristics and Relevant Examples 1. Cylindrical Projections: Mercator and Peters Cylindrical projections project the Earth as if it were enveloped in a cylinder: Mercator projection: ideal for navigation but exaggerates the size of polar regions. Peters projection: maintains real proportions of areas, although it distorts shapes. 2. Conic Projections: Albers and Lambert Conic projections project the surface onto an imaginary cone. They are useful for representing large regions in mid-latitudes: Albers projection: maintains proportional areas and is ideal for climate maps. Lambert projection: frequently used in aviation and meteorological maps. 3. Azimuthal Projections: Gnomonic and Stereographic Azimuthal projections represent the Earth from a central point. Gnomonic projection: useful for planning air routes, since straight lines are the shortest paths. Stereographic projection: widely used in polar and astronomical navigation maps. How Projections Distort the World: Truths and Myths One fascinating aspect of cartographic projections is how they influence our perception of the world. Many people grew up believing that Greenland is almost as big as Africa because of the Mercator map. In reality, Africa is 14 times larger. This distortion is not an error, but an inherent consequence of the projection used. Therefore, cartographers and educators must choose carefully which projection to use depending on the purpose of the map. The Digital Age: Cartographic Projections in Digital Maps and GIS The advent of geographic information systems (GIS) has revolutionized mapping. Thanks to digital platforms, it is possible to switch from a cylindrical to an azimuthal projection in seconds, integrating data layers such as roads, hazard zones and points of interest. When we use mobile applications such as Google Maps, we are interacting with multiple map projections, automatically adjusted according to the zoom level and function required. Applications of Cartographic Projections in Everyday Life Urban Planning and Navigation Cylindrical projection maps are commonly used for transportation and maritime navigation systems. In urban planning, topographic maps based on conic projections allow the analysis of heights and slopes for infrastructure construction. Geomarketing and Business In the business world, digital mapping plays a crucial role in market analysis and logistics. Maps based on accurate projections help companies strategically locate branches and plan more efficient distribution routes. Tourism and Education Interactive maps and augmented reality applications allow tourists to explore cities before visiting them. Educational mapping uses simplified projections to explain geographic concepts clearly and effectively. Current and Future Challenges of Cartographic Projections Artificial Intelligence and Predictive Modeling Artificial intelligence has improved the analysis of geographic data, making it possible to create customized map projections based on real-time data. These advances are critical in areas such as emergency management and smart city planning. Interactive Projections and Augmented Reality Augmented reality allows virtual maps to be superimposed on our physical environment, opening up new possibilities for tourism and education. This technology turns any device into an interactive window into the geographic world, combining accuracy with visual exploration. Conclusion: The Fundamental Role of Projections in Modern Society Cartographic projections have been and continue to be an essential component in understanding our environment. From ancient paper maps to today’s complex GIS systems, cartography has constantly evolved, adapting to the needs of each era. Thanks to advances in AI and geolocation, cartographic projections continue to facilitate accurate representation of the Earth at multiple scales and contexts. By understanding their limitations and strengths, we can appreciate their relevance to everyday life and their potential to transform the way we interact with the world.
