A bar-coded ruler (Sierra RapidScan Ruler) and a mobile computer application system (Sierra DigiTally) are developed to efficiently measure and capture dimension, type, quality, and quantity data of objects with three dimensional measurements, particularly of lumber and similar products. The ruler contains bar codes for measuring and inputting related data. The ruler and the system are mobile and they are carried to field of operation for capturing data electronically. Collected data may be transmitted to another computer by cabled or wireless connection.
