Kathaiguri are proposed in addition to proposed Rajapur- 
Bogibilgaon site as shown in the maps. The major portion of the 
proposed road and rail alignment passes through agricultural land, 
but the railway line near its joining with the existing railway line 
at Chaulkhowagaon between km 9 & 10 passes through 
Chaulkhowa and Jamtara Tea garden, between Km 6 and 7, it 
passes through the Rajabheta Tea garden. Moreover, the proposed 
Dhamalgaon railway station lies in grassland and this part of the 
area upto km 18 of proposed railway line comes under relatively 
low lying area which retains water after heavy rains. This factor 
needs to be consider properly during planning and construction 
stage. Further, bridges are be constructed for railway line 
alignment near Km 17 crosses Larua Jan Nala, between Km 34 & 
Km 35 of proposed railway line and between Km 22 and Km 23 of 
proposed road alignment crosses the Tangani river near Chitalmari 
village. Except above problems, the study indicated that proposed 
rail and road alignment sites for connecting it to existing road and 
rail network appears to be safe. 
5. CONCLUSION 
The results of the above study revealed that landuse/land cover 
information obtained through PAN data would help RITES in 
planning strategies, designing suitable structure, preparing cost 
estimates & financial plans, and drawing rehabilitation programme 
in the vicinity of proposed road and rail alignment sites in the 
study area. Further, it is observed that single crop practice in 
Kharif season mostly paddy is the most common in the area. A 
vast tract of 
alluvial land is used for planting tea in the tea gardens. About 53 
tea gardens were mapped from PAN data in the study area. As 
compared to tea garden area shown in the SOI toposheets of 1963- 
70 period, it is evident from PAN data of 1997 that tea plantation 
area has increased over a period of 30 years as large part of 
cropland and forest land was converted in to tea gardens.
