Lesorub Pro is a leading mobile system and professional timber volume calculator for loggers, sawmill operators, surveyors, log buyers, foresters, and timber truck drivers.
Calculate the volume of roundwood, sawn timber, and tree-length logs with maximum accuracy right at the logging site—the app is completely autonomous and works without an internet connection!
🌲 PROFESSIONAL LUMBER CALCULATION SYSTEMS AND STANDARDS:
• GOST 2708-75 — a complete official reference book on roundwood volumes (basic calculation, top diameter calculation, mast timber, and pit prop).
• ISO 4480-83 — international standard for calculating the volume of roundwood.
• OST 13-232-87 — log-length volume calculator by wood species.
• Professor Anuchin's Tables — calculate the volume of tree trunks by height class.
• Tree-length Volume — precise tables for coniferous and deciduous trees.
• Lumber — calculate the volume and quantity of edged and unedged boards, beams, squares, and slats.
• Smart "Pieces ⇄ Cubes" converter — instantly convert pieces to m³, linear meters, and square meters.
• Wood weight calculator — calculate the weight of a batch for 19 species, taking into account 4 moisture levels (for overload control of timber trucks and road trains).
🪓 CUTTING CALCULATION ON A SAWMILL:
• Interactive geometric modeling of board and beam yield from a log.
• Accounting for kerf thickness (saw cut), slabs, and process waste.
• Percentage of useful yield of finished products tailored to your sawmill parameters.
📷 NEURAL NETWORK AI-BASED LOG SCANNER FROM PHOTO:
• Scans log ends in a stack or truck body using a smartphone camera.
• Automatic recognition of contours, diameters, and number of trunks.
• Calibration ruler (in cm) for precise scale adjustment at any distance.
• Calculation of the stack's full-wood content coefficient and the total cubic capacity of the batch.
• Manual marking and adjustments possible directly on the screen.
• Board package scanner for quick lumber counting.
🤖 AI CONSULTANT "LESORUB AI":
• Built-in expert assistant on forestry, GOST standards, coefficients, and technology.
• Assistance in solving non-standard inventory and sawmilling problems.
📊 ACCOUNTING, ARCHIVING, AND EXPORTING (PDF, EXCEL, CSV):

• Generate ready-made specifications and reports in Excel (XLSX), PDF, and CSV.
• Instantly send statements to customers, partners, or the accounting department via instant messaging and email.
• Cloud synchronization to protect your data when changing devices.
🚜 EQUIPMENT GARAGE AND LOG MAP:
• Special equipment log: harvesters, forwarders, logging trucks (KAMAZ, Ural), skidders, sawmills, chainsaws.
• Monitor maintenance, engine hours, mileage, spare parts, and fuel costs.
• Interactive logging site map: GPS coordinates of logging sites, boundary polygons, area calculations, photo reports, and notes.
• Specialized weather forecast for planning timber haulage on winter roads and unpaved roads.
