Electric transmission line house distribution graph generating method based on GIS mode

Abstract

The invention relates to a house distribution graph generating method applied to a power system, in particular to an electric transmission line house distribution graph generating method based on a GIS mode. The method includes the specific steps of recording and managing properties of a house, automatically numbering the house, renaming batches of house photos, manually grouping of the house, outputting batches of distribution graphs and automatic loading and typesetting of correlated photos. The mode of outputting a house distribution graph in a flat profile graph in the prior art is changed and a GIS data processing method is adopted for directly editing and managing house graphs and property data in a plane graph. The house distribution graphs are output in batches according to a line path and the photos are automatically loaded. The electric transmission line house distribution graph generating method based on the GIS mode has the advantages that the automatic house numbering method is provided, efficiency is improved and subjective errors are avoided. Names of house correlated photos are stored in the house property, the photos are renamed in batches according to the serial number of the house, the house distribution graph is directly output from the house plane graph, middle files are not needed, and therefore house graph processing is more flexible.

Description

technical field [0001] The present invention relates to a method for generating a house distribution map used in a power system, in particular to a method for generating a house distribution map for transmission lines based on a GIS model, which manages data based on a geographic information system (GIS) model and directly outputs power transmission from a plan The method of line house distribution map combines engineering survey and geographic information system technology in the surveying and mapping discipline. Background technique [0002] Explanation of basic terms: [0003] Line coordinate system: An engineering coordinate system with the center line of the line as the horizontal axis and the vertical center line as the vertical axis. It expresses the coordinates of ground objects in terms of accumulative distance and offset distance relative to the center line of the line. Usually, the backsight direction is also called the small direction, and the frontsight directi...

Problems solved by technology

In addition, when outputting a house map, most of the existing public house distribution maps display and output are automatically framed by accumulative distances. Outside the range of starting and ending cumulative distances, some houses may appear at the edge of the frame

2. When there are many houses in the map frame, it is not convenient for the typesetting of house photos
