The current ASPRS PE & RS has an important article on estimating LiDAR point position errors using a simplified analytical model. (You must be an ASPRS member to download the full article from the site.) The authors – Triglav-Cekada, Crosilla and Kosmatin-Fras are attempting to provide a method for predicting the expected average and maximum [...]

1. The September issue of PE & RS has an important paper on the work being done by Dr. Habib and others.
2. A mathematical methodology is being proposed to assess the quality of derived lidar data and the associated system parameters.
3. The goal of this important research is to produce a set of standards for judging the quality of the derived lidar data.

1. There is an opportunity for sensors to become more intelligent.
2. The new Z/I RMK-D digital aerial camera may some day be integrated with a laser scanner to extract features at the sensor.
3. NASA’s High Resolution Stereo Camera is capable of automatically producing stereo images, including quality checks.

The need for breaklines has been debated for a number of years without a clear standard being developed.
Producing contours from a LiDAR survey causes additional issues in the area of breaklines.
Should we still be using contours in a 3D world?
