Figure1 :Methods of spatial and attribute information input in GIS
Although satellite Images can cover the information of large amount of ground, using satellite images with fit spatial resolution need high charge and creating relation between image and ground is time consuming. Therefore , using GPS and computer with fast process rate is suitable [1], but selecting a fast and accurate way that reduces cost, need a special process. In this research a program was written in Visual Basic language, which have relation with a database in SQL Server and can get information of eight GPS with eight external ports. By this method we can collect spatial data from the field quickly (figure2).
Figure2: Designed Software for collecting data by GPS
Some countries like England and Japan have been using the integration of multimedia and GPS method for data collection in their railway.
Omnicom System In England
This system can make information of track and can be used to evaluate the failure of track by integration of film and GPS. this system can make a report of failure of track (Figure 3).
A new and innovated track inspection system solves the problem of walking the track without risk on high speed lines under new safety roles and provides maintenance people with a
