Projection coordinate system setting method for framing geographic space data

The invention discloses a method for setting a projection coordinate system of framing geospatial data, which comprises the following steps of: S1, analyzing the file composition and naming mode of the framing geospatial data in a specified folder, judging whether the file composition and naming mode meet data processing requirements or not, and determining the longitude range of a research area; s2, different projection coordinate system templates are created according to the longitude range, and plane coordinates of the maximum longitude and the minimum longitude of the research area under different projection coordinate systems are calculated; s3, determining projection coordinate systems according to respective file naming modes for framing geographic space data files meeting data processing requirements; s4, according to the projection coordinate system of each framing geographic space data file, updating coordinate system information of each framing geographic space data file; and S5, repeating the step
