Abstract: A method of producing an interactive map using a computer system. The method includes determining graphic data indicative of a visible representation of a map of a geographic area and determining an identity. The computer system then generates coded data indicative of the identity and of a plurality of reference points of the map, and records an association between the identity and a page description, the page description being indicative of a layout of the coded data and the graphic data. The computer system then causes the map to be printed by printing of the graphic data and the coded data onto a surface using the layout.

Abstract: A data structure encoded on a surface of an object, and a method of generating such a data structure. The data structure includes a plurality of block data regions. Each of the block regions includes an encoded data region containing data in encoded form, a clock mark structure located adjacent a first peripheral portion of the encoded data region, and a target structure located adjacent the clock mark structure. Each of the block data regions further includes an orientation data structure indicative of an orientation of the data structure.
