Abstract: A global spatial modeling system and architecture are provided. Each of a plurality of georeferenced boxels provides a whole number georeferenced representation of a location on earth. Each georeferenced boxel has a latitude component, a longitude component, and an altitude component, and can be represented by 10-characters using base64 en coding. A plurality of building element components each represent space or equipment in a building, each building element component being associated with one of the plurality of georeferenced boxels. In an implementation, a method is provided of converting a two-dimensional (2D) building model to a three-dimensional (3D) georeferenced building model. In another implementation, a method is provided to creating a selectable, or clickable, 2D plan.

Abstract: An electronic file certification, validation or comparison method and system. The method includes the steps of: a) receiving a first file at a server from a first user; b) encoding with an electronic tattoo the first file with a first unique serial code to thereby certify the first file; c) encrypting and storing the first file in the server; d) receiving a second file at the server from a second user, the second file having a second unique serial code; and e) comparing the second unique serial code to the first unique serial code. If the serial codes mismatch an e-mail is sent to the second user indicating that the second file is not certified, or else decrypting the first file, and comparing the second file to the decrypted first file. If the files match an e-mail is sent to the second user indicating that the second file is a true copy of the first file, if not it indicates that the second file is not a true copy of the first file.
