LASbased

LASbased refers to a method or approach that utilizes a LAS file as its foundational data source. LAS files are a standard digital format for storing and exchanging airborne laser scanning data, commonly known as LiDAR (Light Detection and Ranging). This data typically consists of a collection of 3D coordinates, intensity values, and other attributes representing points on the Earth's surface and objects upon it.

When an application or process is described as LASbased, it implies that it directly processes, analyzes, or derives information from the raw point cloud data contained within a LAS file. This could involve various geospatial operations such as elevation modeling, feature extraction (e.g., identifying buildings or trees), change detection, or creating topographic maps. The LAS format's widespread adoption in the remote sensing and GIS communities makes LASbased workflows common for projects involving airborne LiDAR data. Its structure is designed to be efficient for storing large point clouds and is supported by numerous software packages. Therefore, a LASbased system leverages the rich, spatially explicit information captured by LiDAR technology in its native format.
