Combination of Multifunctional Laser Measuring Instruments and GPS
In the initial introduction, multifunctional laser measuring instruments were primarily used in combination with GPS. In terrain‑constrained areas, GPS assists the multifunctional laser measuring instrument to complete field surveys.
Specific Applications
Rectification and Inventory of Illegally Reclaimed LandThe integrated application of laser measuring instruments, GPS, GIS and supporting software, combined with portable computers for environmental monitoring, has become a highly popular research project among academic institutions. In forestry, this solution is applied to the investigation and regulation of illegally reclaimed land. However, GPS signals are often restricted by complex terrain, requiring further research and field testing. Digital cameras can also be integrated to photograph illegal activities for archiving and regulatory evidence.
Leased Land InventoryCombining multifunctional laser measuring instruments with GPS for leased land inspection delivers high working efficiency and superior accuracy. Digital maps can be preloaded into portable computers for on‑site comparison and verification during field operations.
Inventory of External Protected ForestsAt present, electronic mapping tablets are adopted for the inventory and stake layout of off‑administrative‑area protected forests. Insufficient triangulation points often slow down overall progress.If high‑precision GPS is used for control point layout, paired with laser measuring instruments for field measurement and coordinate programs for stake positioning, inspection efficiency can be greatly improved, while reducing subsequent map digitization workload.
Compared with traditional compasses, multifunctional laser measuring instruments feature higher accuracy, on‑site data storage, no manual drawing, no measuring ropes, and no manual vegetation clearing. They significantly save time and labor, and support computer‑aided data processing and mapping. Field tests and practical operation have proven their comprehensive advantages over conventional survey tools, making them worthy of wide promotion and application.
