Enclosing wall type geographic information data processing method and device

The invention discloses an enclosing wall type geographic information data processing method and device. The problem that in the prior art, enclosing wall type geographic information symbolic expression and entity storage are not unified is solved. The invention discloses an enclosing wall type geographic information data processing method, which comprises the following steps of: in response to a GUI (Graphical User Interface) instruction, generating a data cluster of enclosing wall ground feature elements; a first data structure of the data cluster comprises spatial position information of at least two nodes, enclosure ground feature element codes, primitive codes and primitive attributes; the primitives comprise line primitives forming enclosing wall skeleton lines, line primitives forming enclosing wall auxiliary lines and surface primitives forming wall surfaces. According to the method and the device, the enclosing wall elements with various widths and shapes are realized and are expressed by an independ
