Water and soil loss dynamic monitoring field investigation information mobile acquisition system and method

Abstract

The invention relates to the field of water and soil loss dynamic monitoring, and discloses a water and soil loss dynamic monitoring field investigation information mobile acquisition system and method. The method comprises the steps of: carrying out water and soil loss dynamic monitoring field investigation and field information acquisition through a mobile terminal; and managing, storing and processing massive spatial data and recheck information through a cloud server, and enabling a mobile terminal to quickly call and display thematic data and monitor remote sensing images in the same period. According to the system and method, flexible calling and rapid display of tens of thousands of soil erosion land parcel data are realized through GIS algorithm optimization, the reasonability of the data can be rechecked and verified synchronously on site, and reference and basis are provided for soil erosion calculation and result analysis. According to the traditional technology, a paper mapand a paper table is printed to record different thematic investigation information, and as a result, accurate positioning and analysis cannot be achieved, and efficiency is low. With the system andmethod adopted, the above problems can be solved.

Description

technical field [0001] The invention relates to the field of dynamic monitoring of water and soil loss, in particular to a key technical method for the construction of a mobile collection system for field investigation information of dynamic monitoring of water and soil loss. Background technique [0002] Water and soil loss monitoring is one of the main contents of ecological environment monitoring. The dynamic monitoring of water and soil loss is based on remote sensing monitoring based on satellite remote sensing and GIS technology. Due to the high accuracy requirements, in order to accurately grasp the information of water and soil loss, it is necessary to rely on the staff to collect a large amount of data and take images on the spot. At present, most of them use manual records to conduct on-site surveys. In the later stage, relevant data and on-site images need to be manually sorted and managed. The monitoring of water and soil loss in the prior art is costly, cumbers...

AI Technical Summary

Problems solved by technology

The dynamic monitoring of water and soil loss is based on satellite remote sensing and GIS technology. Due to the high precision requirements, in order to accurately grasp the information of water and soil loss, it is necessary to rely on the staff to collect a large amount of data and take images on the spot. At present, most of them use manual records to conduct on-site surveys. In the later stage, relevant data and on-site images need to be manually sorted and managed

The monitoring of water and soil loss in the existing technology is costly, cumbersome and time-consuming

In addition, in the dynamic monitoring of water and soil loss, each working unit is composed of tens of thousands of soil erosion plots with spatial information. After the soil erosion plot data is downloaded to the mobile terminal, each data call will The device generates a lot of stress and cannot display as quickly as needed

Existing auxiliary tools only support on-site positioning and navigation of a single pre-selected small number of maps, and cannot classify and review special tasks such as interpreting signs, water and soil conservation measures, and human-disturbed maps and record on-site information

Existing similar mobile terminals cannot support the rapid display and editing of massive vector data, nor can they perform simultaneous verification of on-site soil erosion intensity and vegetation coverage
