Abstract

A method for extracting and analyzing spatial information of a control and protection zone of rail transit with multiple threshold constraints, including the following steps: 1, performing format conversion on a data file and extracting a plurality of coordinate points; 2, selecting key points from the plurality of coordinate points for data simplification to obtain a simplified limit line, a simplified outer structure edge line and a simplified boundary line of construction; 3, programming the simplified limit line, the simplified outer structure edge line, and the simplified boundary line of construction, calling a database, and reading data therefrom for spatial relationship comparison; 4, determining whether the construction of a rail-involved construction project intrudes into a control and protection zone of rail transit according to a result of the spatial relationship comparison, thus completing the extraction and analysis of the spatial information of the control and protection zone of rail transit.
