Several Algorithms about GIS Functions Based on ObjectARX.net
Liu Miaolong · Geomatics & Spatial Information Technology · 2009
Although ObjectARX.net is one of the powerful development tools of the AutoCAD,its ability to treat GIS operations is very limited.Several algorithms are developed about acquiring of the application identifier of one polygon entity,computing the area of one polygon entity and computing the overlapped area between polygon entities during the development of the land information system based on ObjectARX.net.They are realized by programming,and are tested with practical data.The result shows these algorithms are right and feasible.
