摘要：The updating of digital maps has always been a time consuming task, one that many organizations either haveavoided or deferred for years. Digital mapping technology offers the promise of easier-- and therefore,the potential for more frequent updating.lmprovements have been made in creating interactive graphic editingand updating capabilities, yet not all updating scenarios have lent themselves to make such updating fromthe database management system ( DBMS ).We have tested non-graphic updating procedures in a pilot area of 1.5 square kilometers in Giza city inEgypt using ESRI'S ARC/INFO on Micro-Vax computers. The Users recognize that coverage's graphics are maintainedseparatly from the user-accesable attibute database ( INFO files). This is done for good reasonswhich are not questioned here. What we have tested here is an alternative technique for allowing updatingto coordinates and topologies through INFO DBMS without low-level binary management of the graphic files.The proposed technique uses ARC AMLs only and allows linkage to be managed entirely by high-level arcroutines.The primary advantage of such technique is that it allows the updating to be expressed as automatic coordinateschanges with topologies and vise versa. In addition, the developed technique will have significantpotential in improving the inter"races between existing digital maps and any external non-graphic databaseor digital information from external updating sources such as total station, remotely sensed imagery, •. etc
