Problems solved by technology

[0002] In the traditional forest measurement technology, since it is necessary to grasp the detailed information of each sample tree, each sample tree is numbered and a steel hang tag is fixed at the tree height of 1.3m. Retesting is carried out, but due to the long interval between retesting, often due to human or natural factors, the number of the sample wood cannot be confirmed due to the loss of the listing, which has a great impact on the forestry investigation work, but there are obviously good methods to solve this problem at home and abroad

Embodiment Construction

[0010] The reset method of forest sample trees using total station as a tool is different from the existing methods, specifically in that:

[0011] (1) Establish a measurement control point at point O in the center of the forest stand. It is required that the cement pouring steel nails can be permanently preserved, and a prism-free total station is installed to measure the coordinates of each sample tree in the stand, and store them in the PDA in real time while ensuring The number of each sample tree corresponds to the coordinates one by one;

[0012] (2) When the sample wood information was measured for the second time, it was found that the sample wood numbered P was lost, and the sample wood could not be found. Using the control point O, the coordinate information of the sample wood P and any sample wood A, use the polar coordinates Model ① β = α OP - α OA = ...

Abstract

The invention discloses a forestland sample tree resetting method treating a total station as a tool. The total station is treated as the tool to accurately measure the coordinates of all sample trees in a forestland, all the sample trees are listed and numbered, data storage is carried out through PDA (Personal Digital Assistant), and sample trees losing numbers can be accurately found through resetting the sample trees by utilizing the polar coordinate method of the total station when the second-time sample tree information measurement is carried out, so the forestland sample tree resetting method is a new technology for solving the sample tree position loss problem in the forestry field investigation work.

Description

1. Technical field [0001] The invention relates to a technology for resetting a sample tree in forest investigation, in particular to a method for resetting a sample tree by using a total station together with a PDA (Personal Digital Assistant, personal electronic assistant). 2. Technical background [0002] In the traditional forest measurement technology, since it is necessary to grasp the detailed information of each sample tree, each sample tree is numbered and a steel hang tag is fixed at the tree height of 1.3m. Retesting is carried out, but due to the long interval between retesting, often due to human or natural factors, the number of the sample wood cannot be confirmed due to the loss of the listing, which has a great impact on the forestry investigation work, but there are obviously good methods to solve this problem at home and abroad . [0003] The present invention obtains the coordinate information of each sample wood by using a total station, and at the same ...
