Digital Elevation Models - Variations in Resolution

Caption: Figure 1A: A high-resolution (1 meter Lidar) close-up of a pinnacle, showcasing detailed structural features. In contrast, Figure 1B, captured at a coarser resolution (10 meter 3DEP), appears pixelated and cannot accurately be described for its geological structure. Figure 2 demonstrates the same structure at a larger scale, with Figure 2A (1 meter Lidar) revealing intricate topography and detailed features. In contrast, Figure 2B (10 meter 3DEP) appears blurry even at this scale. Legacy elevation models, characterized by lower resolutions (10 & 30 m), are often inadequate for precision management activities. A great example of this is the difficulty in generating an accurate least-cost path in steep and rugged terrain. A 10m resolution model may be too coarse, leading to paths that traverse features that are not manageable or within specifications. In contrast, a 1m resolution model can accurately identify even the smallest rock outcroppings, enabling the creation of a precise and effective least-cost path.
