Discussion on the application of multifunctional laser measurement system in forestry
(1) Forest land survey
Since the multifunctional laser measurement system combines laser ranging and electromagnetic digital compass, its distance measurement and angle measurement accuracy are much higher than those of compasses and measuring ropes. It is actually the best new instrument for forest land measurement.
According to the test, the advantages of using the multifunctional laser measuring instrument for forest land measurement are:
1) Easy to operate, fast measurement locking and high accuracy. The instrument can automatically record data and transmit it to the computer without human clerical errors.
2) The digital instrument panel displays automatically without human error in visual interpretation.
3) Save manpower and time.
4) Comes with processing software, which can process points, lines, and wires and calculate closing errors, areas, etc., and can be connected to a printer or plotter to directly draw measurement graphics.
(2) Combination of multifunctional laser measuring instrument and GPS
The introduction of multi-functional laser measuring instruments was initially mainly combined with GPS, that is, GPS was used in conjunction with multi-functional laser measuring instruments for measurement in areas with restricted terrain.
application:
1) Censorship and inventory of illegally cultivated land
The use of laser measuring instruments, combined with GPS, GIS and their software, and portable computers for environmental monitoring is currently the most popular research project in various academic institutions. In forestry, it is used for illegal land clearing and inventory. However, since the use of GPS may be restricted by terrain, further research and testing are needed. In addition, it can also be combined with a digital camera to take photos of violations and archive them to provide evidence for banning.
2) Land rental inventory
The combination of multi-functional laser measuring instrument and GPS to carry out land lease inspection is not only fast but also highly accurate. In addition, the digital drawing files can also be pre-entered into a portable computer and brought to the site for inspection and comparison.
3) Inspection of security forests outside the area
At present, the bureau uses electronic flat-panel instruments to conduct inventory and stake placement work in security forests outside the area. However, due to insufficient triangulation points, inventory work is often slow. If centimeter-grade GPS can be used to lay out points, and then a laser measuring instrument can be used for measurement, and the target coordinate program function can be used for staking work, it should be able to speed up the inventory work and reduce the subsequent work of digitizing maps.
