Partition-Based Complete Surface Object Surveying and Mapping Operation Method

Abstract

The invention relates to an integral ground feature mapping working method based on partitioning. The integral ground feature mapping working method comprises the following steps: (1) partitioning ground features: partitioning the ground features to be detected to form measuring units, wherein all the measuring units take a cadastral street, a lane boundary line, a water system central line and a road central line as boundary lines so as to maintain the integrality of the ground features and corresponding side boundaries between the adjacent measuring units are overlapped; (2) carrying out field measurement; and (3) carrying out office work treatment. Aiming at a current working manner, the integral ground feature mapping working method is convenient for field annotation / mapping and the edge snapping work amount of office work is reduced; the partitioning is reasonable so that river-spanning and road-spanning work is reduced to the greatest extent and result data is prevented from being cut; the edge snapping work amount is eliminated basically and the integrality of the ground features is maintained to the greatest extent. The integral ground feature mapping working method based on the partitioning is applicable to a field working mode; the edge snapping work amount is nearly zero and the edge snapping work amount of traditional framing data accounts for 1%-3% of the working amount of a whole picture; the integrality of the ground features is effectively maintained and the integral ground feature mapping working method is applicable to data management.

Description

technical field [0001] The invention belongs to the field of surveying and mapping operations, in particular to a partition-based complete surface object surveying and mapping operation method. Background technique [0002] At present, my country's basic surveying and mapping operation mode can be roughly summarized as: field surveying / repair surveying by map sheet-in-house processing-arrangement and storage. The framing in the existing surface object surveying and mapping method adopts rectangular framing or trapezoidal framing according to the "National Basic Scale Topographic Map Framing and Numbering". This kind of framing method has the following problems in surveying and mapping operations: 1. For example, if the house to be measured crosses the framing line, there is a part in each of the two pictures. If the two pictures are distributed to different survey teams for side repair, then in order to ensure the integrity of the ground features, the house It will be measu...

The framing in the existing surface object surveying and mapping method adopts rectangular framing or trapezoidal framing according to the "National Basic Scale Topographic Map Framing and Numbering". This kind of framing method has the following problems in surveying and mapping operations: 1. For example, if the house to be measured crosses the framing line, there is a part in each of the two pictures. If the two pictures are distributed to different survey teams for side repair, then in order to ensure the integrity of the ground features, the house It will be measured once by two surveying teams; due to the limitation of framing and natural conditions, field surveying / mapping is often transferred to the opposite bank because the map crosses the river, and the results of the piece-by-piece measurement need to be cut into framing results , which increases the workload, also causes inconvenience to the work, and destroys the integrity; 2. In the office, whether it is new surveying, editing, repairing, or downsizing, edge joining is a necessary process, and the work of edge joining The amount of data is very large, which takes up a lot of time for data processing, and errors and errors in the joining process are unavoidable, which will artificially lose data accuracy and hinder the improvement of data quality
