Abstract:Performing meaningful network analyses is greatly dependent upon accurate and
complete transportation network models, which are digitized into a Geographic
Information System (GIS) or, more often, imported from another GIS.
Transportation networks can be converted thoroughly between different GISs if
they model semantically similar features. Such is the case with Arc/Info
Network (by ESRI) and MGE Network (by Intergraph). The graphic features modeled,
associated attributes, topology, and metadata can be translated between the two
GISs via the Spatial Data Transfer Standard (STDS). In particular, the draft
Transportation Network Profile (TNP) of the STDS has been used to experiment
with this type of conversion. This paper compares the two GISs' transportation
network modeling capabilities, briefly discusses the functionality of a
software utility (written for a Geography Masters' thesis) to convert
transportation networks between the two GISs, and assesses the usefulness for
the Transportation Network Profile of the STDS. 12p.
