Processing of digital map data continues to be time consuming and subject to various types of errors. This paper describes a process, designed and developed by the author, for building topological networks that reduce processing time while significantly increasing data accuracy. The RAND Topological Editor employs a semi-automated editing system with human supervision to enhance the accuracy of geographic data. RTE has been used to build a large transportation network, a project that involved more than one hundred maps.
