A time-space conversion method of flight sequencing information aims to solve a problem that a flight sequencing suggestion generated by an arrival management system has poor effect in practical application due to abstract characteristics, comprising: generating a sequencing time and a delay suggestion of a flight in each key point in a terminal area and each runway by using a flight sequencing technology; predicting a flight status of the flight according to a current position and 4D trajectory information of the flight, and filtering a delay-consumed flight segment, and on that basis, generating a flight segment delay allocation strategy with reference to an aircraft performance and sequencing information, and obtaining a flight segment delay allocation result; and generating a visual spatial position reference target according to the flight segment delay allocation result and an operation deviation limit.

The present invention discloses a method and an apparatus for extracting mountain landscape buildings based on high-resolution remote sensing images. The method comprises: segmenting a remote sensing image, and extracting non-vegetation areas from the remote sensing image by using NDVI; segmenting the non-vegetation areas, and extracting building areas by using NDBI; segmenting the building areas again, and calculating a normalized difference build shadow index NSBI of each patch; calculating NSBI separator of each patch in the non-vegetation areas and setting a separator threshold, and extracting landscape building areas based on the threshold. In the present invention, by introducing a near infrared band in the remote sensing image spectrum, in which there is a significant difference between shadows and non-shadows, the influence of large shadow areas in mountainous shady areas in the remote sensing image on the result of extraction is reduced.
