Multi-function laser surveyor combined with GPS
The introduction of the multifunctional laser surveyor was initially combined with GPS, i.e., GPS was used in conjunction with the multifunctional laser surveyor in areas where the terrain was restricted.
Specific applications:
1) Abusive Land Reclamation and Inventory
The use of laser measurement instruments in combination with GPS, GIS and its software, together with portable computers for environmental monitoring is currently a popular research project in various academic institutions. In the forestry industry, it is being used for the suppression and inventory of abandoned land, but since the use of GPS may be limited by the terrain, further research and testing is needed. In addition, it can be combined with a digital camera to capture and archive illegal situations for evidence of enforcement.
2) Leased Land Inspection
The combination of multi-functional laser surveyor and GPS can be used to conduct land survey, which is not only faster, but also with a higher ** degree. In addition, we can also input the digitised maps into a portable computer in advance and carry them to the site for inspection and comparison.
3) Outside Security Forest Inventory
At present, the Bureau adopts the electronic tablet device to carry out the inventory and staking work of the security forests outside the district. However, due to insufficient triangulation points, the work is often slow. If we can make use of the public grade GPS to lay out the points, then use the laser surveyor to carry out surveying, and make use of the function of the target coordinate programme to release the stakes, it should be able to speed up the inventory work and reduce the aftermath of the cadastral data processing work.
Multi-functional laser surveyor has the advantages of high accuracy, record-free, drawing-free, rope-free, grass-free, time-saving, labour-saving and computer processing, drawing, etc. Compared with the traditional compass, it has been tested in the field and operated on the spot, and it has exceeded the previous instruments, which is worth to be promoted.
