Discussion on the application of multifunctional laser measurement system in forestry
(A) forest land survey
Because the multifunctional laser measuring system combines laser ranging and electromagnetic digital compass, its ranging and angle measuring accuracy is much higher than that of compass and rope measuring, and it is really a good new instrument for forest land measurement.
According to the test, the advantages of multifunctional laser measuring instrument applied to forest land measurement are as follows:
1) Simple operation, fast measurement and locking, and high precision. The instrument can automatically record data and transmit it by computer, and there is no human error.
2) The digital dashboard automatically displays, and there is no human visual interpretation error.
3) Save manpower and time.
4) Attached with processing software, it can process points, lines and wires, calculate the closing difference and area, and can be connected to a printer or plotter to directly draw measurement figures.
(B) Multi-function laser measuring instrument combined with GPS
At the beginning, the introduction of multifunctional laser measuring instrument was mainly combined with GPS, that is, GPS cooperated with multifunctional laser measuring instrument to measure in areas with limited terrain.
Specific application:
1) Banning and checking of land reclamation.
At present, the combination of laser measuring instrument with GPS, GIS and its software and portable computer for environmental monitoring has become a hot research project in various academic institutions. In forestry, it is used to ban and check the wasteland, but because GPS may be limited by terrain, it needs further research and testing. In addition, it can also be combined with a digital camera to photograph and archive the violations for evidence of banning.
2) Land lease inventory
Multi-function laser measuring instrument combined with GPS is not only fast, but also accurate. In addition, you can also pre-input digital drawings into a portable computer and bring them to the site for inventory and comparison.
3) security forest inventory outside the area
At present, electronic flatbed instrument is used to check and put piles in the security forest outside the area of this bureau. However, due to the lack of triangle points, the inventory work is often slow. If we can use centimeter-level GPS to arrange points, then use laser measuring instrument to measure them, and use the function of target coordinate program to put piles, it should speed up the inventory work and reduce the post-event database work.
