    1. Traditional Photogrammetry vs. LiDAR

    2. What are some of the LIDAR data products available? Digital Ortho-Rectified Imagery Some LiDAR providers collect digital color or black-and-white ortho-rectified imagery simultaneously with the collection of point data. Imagery is collected either from digital cameras or digital video cameras and can be mosaiced. Resolution is typically 1m. Intensity Return Images Images may be derived from intensity values returned by each laser pulse. The intensity values can be displayed as a gray scale image. LIDAR Derived Products Topographic LiDAR systems produce surface elevation x, y, z coordinate data points. There are many products that can be derived from raw point data. Most LiDAR providers can derive these products upon request: Digital Elevation Models (DEMs) Digital Terrain Models (DTMs) (bald-earth elevation data) Triangulated Irregular Networks (TINs) Breaklines - a line representing a feature that you wish to preserve in a TIN (example: stream or ridge) Contours Shaded Relief Slope & Aspect
