Construction project data connection method based on geographic spatial position

The invention relates to the technical field of data security and protection of information technology, in particular to a construction project data connection method based on a geographic spatial position. Comprising the steps of dividing independent units, generating a geographic spatial position index database, extracting a code set of a land parcel, generating an index database of the land parcel, matching project data, generating a project associated data index database and the like. According to the method, the spatial geographic position is associated with the building project data, the characteristic that the keyword of the original building project data can only be digital is created, the advantage of the GIS spatial position is integrated, the current situation that the building project data is difficult to match and associate is changed in an unconventional mode, unified and effective utilization of the system data is realized, and the construction project data matching efficiency is improved.
