of any 3-dimensional x,y,z tuplet. LAS is a binary file format that maintains information specific to the lidar nature of the data while not being overly complex. • RMSE – abbreviation for root mean square error; a measure of the accuracy of the data similar to the measure of standard deviation if there is no bias in the data. • Accuracy. zFrom Las specification. X, Y, and Z scale factors: The scale factor fields contain a double floating point value that is used to scale the corresponding X, Y, and Z long values within the point records. The corresponding X, Y, and Z scale factor must be multiplied by the X, Y, or Z point record value to get the actual X, Y, or Z coordinate.
