Introduction:
It is observed that the relocation of an existing service is not only difficult but also not viable economically (especially in Indian context). But if some rational criterion such as demand weight distance is followed for additional locations geographical accessibility and efficiency level of services can be improved. Here we want to show the distribution of services and proposed additional services.

Terrain Analysis of Study Area
Road from Laigi village to Achumpara (Arunachal Pradesh) has been tentatively identified on topo map no.83 1/5 of SOI & by remote sensing satellite the same needs to be confirmed or suggest other alternative alignment, road elevation near laigi village is 720 m. since the maximum water level of lower Subansiri hydro electric project is fixed at 208.25m, bridge across site has to be fixed at a suitable location above the submergence zone, say 220m, where firm bank is available. The road will have to negotiate along high hills of Rela-Modi to arrive at south facing hills near Achumpare tentative alignment proposed on topo map is as follows:

• On feasible, evaluate earthwork and draw the road alignment on a map drawn to a suitable scale.
• Contour map at 2meter interval considering gradients of 1:15 to 1:20, (a tentative alignment has been drawn on topo map no: 83 1by 05.)

Image Identification.

Scope:

1. Assessment and feasibility of road alignment through Rela-Modi hills by interpreting the Remote Sensing Images (IRS-Id pan & Liss) data.
2. Slope and Terrain analysis of the proposed road alignment on a map drawn to a suitable scale for development project.
3. Preparation of Contour Map at 2-meter interval.
4. Ground control points to be determined and verified with the Clint’s representative by field survey / ground survey.
5. Estimation of Bio-Mass & Local utilization ratio in those areas.
6. Preparation of logistic Master plan for those areas.

Inputs:

1. Topo Maps, Block Maps and Base line information on Road.
2. Remote Sensing Data (images). To collect various data for individual Block level information on Project area, it is required 5m resolution images in black and white and 20m (Liss) resolution images in color to determine Forest cover, Digital Terrain Model (DEM) and various Physical data by Image Processing methodology.
3. If required Topographical maps (1:50,000 scale), cadastral (block) maps to be provided be prepared (available maps can be taken from the department).
4. High-density base line information.
5. Existing road map of the area.
