Introduction:
Optimization of using railway in each country is essential for political and economical development ,Because large amount of goods and passenger and commercial and economical exchange by railway.
In each system essential assets like, construction, installation, machines, factories and so on, can cause growth and progress, so for accurate proper management and precise and updated information is necessary.
After analyzing, recognition and primitive design, one of the important things for GIS Implementation is data acquisition. Collecting and organizing data in digital format is necessary for creating GIS in each system [5].
Spatial data acquisition, storing and organizing them can be done by different methods and have important role in the GIS activities.
Available information in railway industry such as, plane and profile of track, stations, features (objects) in the buffer of rail track, geometric information (Superelevation, Curve, slope, ?) technical construction (Tunnel, Bridge, Drainage, Territory walls, Buildings ,?), train and wagon have spatial attribute characteristics that can be organized by GIS.
In this article we introduce a method that work by integrating of GPS and Multimedia system. This can be used as a tested and successful method by different organization.
Data Acquisition And Information Management In GIS There are different methods for data acquisition from field, Using Traditional or digital maps, satellite images, Global positioning system(GPS), each of this methods have advantages and disadvantages. for example preparing digital railroad map by digitizing the paper of them can
