ASPRS recommends that all mapping professionals adhere to and follow these guidelines when generating or contracting for mapping products derived from LiDAR data. As part of the LiDAR Committee's Working Group efforts, the ASPRS guidelines were harmonized with the relevant sections of the Guidelines for Digital Elevation Data (Version 1.0) released by the National Digital Elevation Program (NDEP).
The guidelines cover the recommended methods for measuring and reporting the vertical accuracy of elevation data recorded by airborne LiDAR mapping instruments. Essentially, they outline necessary steps to analyze the vertical accuracy of elevation data generated using airborne light detection and ranging or laser radar (LiDAR) technology. In addition, the Guidelines cover determining what level of accuracy can be associated with a mapping product, such as a contour map, that is generated from a given LiDAR data set (or conversely, what level of accuracy is required in the LiDAR data to support a given contour interval map). Finally, they also include recommendations for the proper planning and implementation of appropriate ground checkpoints to support a LiDAR data set, including how to handle different land cover classes across a project site.
ASPRS strongly encourages all LiDAR stakeholders to incorporate these guidelines into their LiDAR mapping projects. A copy of the guidelines can be downloaded from the LiDAR Committee section at www.asprs.org (under the Photogrammetric Applications Division) or requested from email@example.com . Other LiDAR guidelines currently under development by ASPRS for release in 2004 and 2005 include "Horizontal Accuracy Reporting," "Sensor Calibration," and "Laser Eye Safety.
