Discussing the application of multifunctional laser measuring system in forestry
(1) Forest measurement
Due to the combination of laser ranging and electromagnetic digital compass in a multifunctional laser measurement system, its ranging and angle measurement accuracy is much higher than that of compasses and measuring ropes, making it the best new instrument for forest measurement.
The advantages of using a multifunctional laser measuring instrument for forest measurement are:
1) Easy to operate, fast measurement locking, and high accuracy. The instrument can automatically record data, transmit it through a computer, and there is no human error.
2) The digital dashboard automatically displays without any human visual error.
3) Save manpower and time.
4) Equipped with processing software, it can handle points, lines, and wires, calculate closure errors, areas, etc., and can be connected to printers or plotters to directly draw measurement graphics.
(2) Multi functional laser measuring instrument combined with GPS
The introduction of multifunctional laser measuring instruments was initially mainly combined with GPS, that is, GPS was used in conjunction with multifunctional laser measuring instruments for measurement in terrain restricted areas.
Specific application:
1) Prohibition and investigation of excessive land reclamation
The combination of laser measuring instruments with GPS, GIS and their software, combined with portable computers for environmental monitoring, is currently the most popular research project in various academic institutions. In forestry, it is used for the prohibition and inventory of overexploited land, but further research and testing are needed due to terrain limitations when using GPS. In addition, digital cameras can also be used to capture and archive violations as evidence for enforcement.
2) Land rental inventory
The combination of a multifunctional laser measuring instrument and GPS for land rental inspection is not only fast, but also has a high degree of accuracy. In addition, digital image files can also be pre inputted into a portable computer and carried to the site for inspection and comparison work.
3) Clearing of security forests outside the area
At present, the security forest outside this area is being inspected and piled up using electronic flatbed machines. However, due to insufficient triangulation points, the inventory work is often slow. If centimeter level GPS can be used for point layout, then laser measuring instruments can be used for surveying, and the target coordinate program function can be used for pile placement work, it should accelerate the inventory work and reduce the post mapping and data collection work.
