Elevation
Various forms of elevation data exist for Texas. Forms of these data include digital contour lines (hypsography), digital elevation models, and the latest elevation technology that involves airborne sensor technology and is known as Light Detection And Ranging (LiDAR). This technology uses a laser and sensor to transmit and receive pulses reflected from surfaces. These return pulses form a point cloud which represents elevation heights of features such as vegetation, buildings, and bare earth (ground).
