4. Landsat TM data were set to classify land 
covers with the surpervised maximum- likelihood 
classify. These classification categories were forest 
area; agriculture area; urban area and artificial 
building area; water and road systems. The classified 
vegetation map store in the system. 
5. Field investegation data input to the 
system. 
CREATING A GIS SYSTEM FOR 
RAILWAY DESIGN 
This GIS information system for railway deign 
contains 7 information planes (IPS) 
1. Topographic information plane. 
This is the basic map to determine the railway 
line location and profile. This IP can garantee the 
engineering design accuraccy. 
2. Geological and hydrological information 
plane 
737 
On this IP, the designer keeps the railway line in 
“the strongest geological foundations and avoids natural 
hazards. 
3. Vegetation information plane. 
On this IP, the designer can calculate that how 
many argriculture and forest areas are in the route 
corridor. 
4. House and artificial building information 
plane. 
On this IP, the designer can calculate how many 
area of the house and artificial building have to move 
out from this route corridor. 
5. Water and road system information plane. 
On this IP, the designer can determine the 
railway line, how to across the river and road 
system. How many bridges will be built in the route 
corridor.
