In order to further demonstrate the error and accuracy in the application of GPS area measurement area, this study first used a compass to measure the area of ​​five forests with different sizes, gradients, and uses, in order to accurately set the average of three replicates. The known area is compared and compared several times, and then the statistical calculation method is used for error calculation and accuracy analysis.
The absolute error of forestry area measurement in traditional forest forest compasses is generally between 0.030 and 0.044. The precision of forest land area increases with the increase of area, and the accuracy increases accordingly. The error is opposite to this, that is, it becomes smaller accordingly. In the conventional cutting area survey design, the compass is used to measure the wire and measure the boundary and area of ​​the cutting area. This method is greatly affected by environmental factors. In particular, the cutting class is usually tree-lined and shrub-grown, and conventional measurements are conducted. The operation is very difficult and it is much more convenient to use a mobile GPS area meter to measure the area.
The GPS area measuring instrument adopts dynamic threshold method to improve the survey design of cutting area surveys, which can overcome the difficulties caused by vegetation invisibility and slope of the slope. The instrument system makes it easier for survey and design personnel to record the boundary coordinates of the cutting area in real time. The GPS area meter can be easily divided to find the area of ​​the cutting area. In short, the effectiveness of the instrument's measurement work in the forest has been greatly improved, and the improvement of work efficiency is a clear advantage.
Brief Introductions of Reaming Shells
Reaming shell is used to couple the drill bit with the core barrel. It is suitable for use on all conventional and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This type of diamond tool is physically longer than the standard type. So for the compensation of the difference in reaming shell length, an appropriate inner tube extension is necessary to be used.
Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use.
Features of Reaming Shells
1) Acts as a stabilizer for drill bit.
2) Be set with natural or synthetic diamond.
Our reaming shells enjoy the best quality and most special design in the industry. With several different types, we try our best to satisfy any of your requirements.
Traditional measurement is difficult to measure in the forest. GPS area measurement instrument developed with the advancement of science and technology can play a unique role and unique advantages. Through this technology, the precise location and the area size of the forest can be satisfactory applications. . At the same time, the analysis of the distribution and density of the forest can be further completed. The GPS area meter plays a crucial role in the forestry work. Its application has provided strong support for the management models of information forestry and digital forestry. Gradually improving the application of GPS area measuring instruments in forestry will bring about certain economic benefits.
