In this paper, we present 3D vector watermarking for GIS (geographic information system) digital map based on DXF file format. 3D GIS digital map consists of various layers including vector data of geometric components, topology and metadata and rater data of satellite data. The proposed scheme selects the area distribution of polygon component and the line distribution of polyline component to the embedding target, which they are base components in GIS vector data. Experimental results verified that the proposed scheme has the robustness to RST, data or layer cutting and rearrangement and other geometric attacks as well as the invisibility of the watermark.
